decision maker preferences for international legal cooperation why do some decision makers prefer big multilateral agreements while others prefer cooperation in small clubs does enforcement encourage or deter institutional cooperation we use experiments drawn from behavioral economics and cognitive psychology along with a substantive survey focused on international trade to illustrate how two behavioral traits patience and strategic reasoning of individuals who play key roles in negotiating and ratifying an international treaty shape their preferences for how treaties are designed and whether they are ratified patient subjects were more likely to prefer treaties with larger numbers of countries and larger long term benefits as were subjects with the skill to anticipate how others will respond over multiple iterations of strategic games the presence of an enforcement mechanism increased subjects willingness to ratify treaties however strategic reasoning had double the effect of adding enforcement to a trade agreement more strategic subjects were particularly likely to favor ratifying the agreement we report these results for a sample of 509 university students and also show how similar patterns are revealed in a unique sample of ninety two actual us policy elites under some conditions certain types of university student convenience samples can be useful for revealing elite dominated policy preferences different types of people in the same situation may prefer to approach decision making tasks and reason through trade offs in materially different ways

voting over economic plans we review and provide motivation for a one sector model of economic growth in which decisions about capital accumulation are made by a political process if it is possible to commit for at least three periods into the future then for any feasible consumption plan there is a perturbation that is majority preferred to it furthermore plans that minimize the maximum vote that can be obtained against them yield a political business cycle if it is impossible to commit voters select the optimal consumption plan for the median voter

option value of gasification technology within an emissions trading scheme investment analysis is mostly implemented with discounted cash flow dcf methods such as the net present value npv the problem in a typical application of these methods is the limited ability to value real options management s ability to adapt to changing market conditions or to revise decisions this paper presents a simulation model in which the investment is regarded as a single firm problem in an operating environment with multiple exogenous and stochastic prices the simulation model is used to explore the impact of emissions trading and in particular the european union emissions trading scheme eu ets on investments in integrated gasification combined cycle igcc plants two real case studies are presented modifications of an existing condensing power plant and a new combined heat and power plant the benefit of the selected approach is that it can take into account the value of multiple simultaneous real options better than a standard dcf analysis the results show that a straightforward application of dcf analysis can lead to biased results in competitive energy markets within an emissions trading scheme where a number of uncertainties potentially combined with several real options can make quantitative investment appraisals very complex

a statistical model for multiparty electoral data we propose an internally consistent and comprehensive statistical model for analyzing multiparty district level aggregate election data this model can be used to explain or predict how the geographic distribution of electoral results depends upon economic conditions neighborhood ethnic compositions campaign spending and other features of the election campaign or characteristics of the aggregate areas we also provide several new graphical representations for help in data exploration model evaluation and substantive interpretation although the model applies more generally we use it to help resolve an important controversy over the size of and trend in the electoral advantage of incumbency in great britain contrary to previous analyses which are all based on measures now known to be biased we demonstrate that the incumbency advantage is small but politically meaningful we also find that it differs substantially across the parties about half a percent for the conservatives 1 for the labor party and 3 for the liberal party and its successors also contrary to previous research we show that these effects have not grown in recent years finally we are able to estimate from which party each party s incumbency advantage is predominantly drawn

investment risks under uncertain climate change policy abstract this paper describes results from a model of decision making under uncertainty using a real options methodology developed by the international energy agency iea the model represents investment decisions in power generation from the perspective of a private company the investments are subject to uncertain future climate policy which is treated as an external risk factor over which the company has no control the aims of this paper are to i quantify these regulatory risks in order to improve understanding of how policy uncertainty may affect investment behaviour by private companies and ii illustrate the effectiveness of the real options approach as a policy analysis tool the study analysed firms investment options of coal and gas fired power plants and carbon capture and storage ccs technologies policy uncertainty is represented as an exogenous event that creates uncertainty in the carbon price our findings indicate that climate policy uncertainty creates a risk premium for power generation investments in the case of gas and coal fired power generation the risk premium would lead to an increase in electricity prices of 5 10 in order to stimulate investment in the case of ccs the risk premium would increase the carbon price required to stimulate investment by 16 37 compared to a situation of perfect certainty the option to retrofit ccs acts as a hedge against high future carbon prices and could accelerate investment in coal plant this paper concludes that to minimise investment risks in low carbon technologies policy makers should aim to provide some long term regulatory certainty

valuation of marginal co2 abatement options for electric power plants in korea the electricity generation sector in korea is under pressure to mitigate greenhouse gases as directed by the kyoto protocol the principal compliance options for power companies under the cap and trade include the application of direct co2 emission abatement and the procurement of emission allowances the objective of this paper is to provide an analytical framework for assessing the cost effectiveness of these options we attempt to derive the marginal abatement cost for co2 using the output distance function and analyze the relative advantages of emission allowance procurement option as compared to direct abatement option real option approach is adopted to incorporate emission allowance price uncertainty empirical result shows the marginal abatement cost with an average of 14 04 ton co2 for fossil fueled power plants and confirms the existence of substantial cost heterogeneity among plants which is sufficient to achieve trading gains in allowance market the comparison of two options enables us to identify the optimal position of the compliance for each plant sensitivity analyses are also presented with regard to several key parameters including the initial allowance prices and interest rate the result of this paper may help korean power plants to prepare for upcoming regulations targeted toward the reduction of domestic greenhouse gases

incomplete information and ideological explanations of platform divergence one of the paradoxes of formal spatial voting models is the robustness of the theoretical result that candidates will converge toward centrists positions and the empirical observation of persistent policy divergence of candidates a solution is that candidates are ideological have policy preferences when candidates have policy preferences and incomplete information about voter preferences then platform divergence is theoretically predicted experimental tests of the ideological model are presented it is shown that platform divergence is significant when candidates are ideological and have incomplete information about voter preferences however candidate positions are more convergent on average than the theory predicts suggesting that subjects value winning independently of the expected payment

income risk of eu coal fired power plants after kyoto coal fired power plants enjoy a significant advantage relative to gas plants in terms of cheaper fuel cost this advantage may erode or turn into disadvantage depending on co2 emission allowance price financial risks are further reinforced when the price of electricity is determined by natural gas fired plants marginal costs we aim to empirically assess the risks in eu coal plants margins up to the year 2020 parameter values are derived from actual market data monte carlo simulation allows compute the expected value and risk profile of coal plants earnings future allowance prices may spell significant risks on utilities balance sheets

decarbonising the power sector via technological change differing contributions from heterogeneous firms abstract in the power sector technological change is a key lever to address the decarbonisation needed to avoid dangerous climate change policy makers aim to accelerate and redirect technological change by targeting relevant firms via climate policy e g the european union emissions trading system eu ets and climate relevant technology policies e g feed in tariffs changes in firm s behaviour i e their research and development r d as well as diffusion activities are at the heart of technological change however firms are heterogeneous actors with varying attributes which perceive policy differently hence they can be expected to react very heterogeneously to these new policies based on an original dataset of 201 firms we perform a cluster analysis grouping firms along their r d and diffusion activity changes we then compare these clusters with regards to the characteristics of the contained firms our analysis results in seven clusters showing very diverse contributions to low carbon technological change suggesting potential for policy to become more effective a comparison of the firms characteristics allows us to derive indicative recommendations on how to adjust the policy mix in order to induce contributions from most firms in the power sector

considering risks in early stage investment planning for emission abatement technologies in large combustion plants fossil fuels will continue to be the most important energy source for electricity generation in most parts of the world for the next decades therefore emission abatement technologies in large combustion plants are an important measure to reduce the emission of pollutants and to lower the negative effects thereof for humans animals and the environment investment decisions for emission reduction measures are however facing various kinds of risks and uncertainties caused by political technological economic and legal influences the consideration of these risks in early stage investment planning is often complex yet important for investors this paper investigates the possibilities to consider risks and uncertainties in early stage investment and cost calculation methodologies of different complexity the real options analysis is presented as well as less complex methods such as monte carlo or sensitivity analyses that lower the calculation effort the application of a specifically developed risk portfolio is recommended before quantitatively investigating risks this portfolio helps to identify the most critical risks and to focus on them reducing again the calculation effort the presented approach is not only of interest for investors but also for policies especially if data is scarce or uncertainties exist regarding specific plant parameters or cost and price components the content of this paper is presented using the example of nitrogen oxide emission reduction measures it is however possible to transfer the results to other pollutants or technologies in a related context

money talks deterring quality challengers in congressional elections j 4t e examine the role of incumbent fundraising in deterring strong challengers we construct vf v a signaling model in which incumbents can use fundraising strategically to ward off w v quality challengers we show however that only under very limited circumstances will there be an observable relationship between fundraising and challenger quality therefore previous empirical tests for deterrence have systematically underestimated the effects of fundraising in decreasing electoral competition our analysis also suggests that by making fundraising easily observable federal election commission regulations may encourage candidates to overinvest time and resources accumulating large war chests instead of governing

barriers to competition and the effect on political shirking 1953 1992 economists and political scientists have offered a variety of explanations for why legislators might rationally choose to ignore the preferences of their constituents political parties and presidents the broad conclusion of this literature is that there is an element of shirking in congressional voting the objective of this paper is to suggest that the effects of shirking in congressional voting may have increased over time largely in response to the raising of barriers to competition in congressional elections thereby enabling legislators to vote their own preferences without fear of losing reelection we use a quasi experimental design that controls for the effects of party region electoral safety presidential control of the white house and constituency factors in isolating the causal effects of barriers to entry on a continuous series of roll calls regarding the raising of the debt limit between 1953 and 1992 we find that shirking in legislative voting on debt limit legislation is a post 1970s phenomenon

review of renewable energy investment and financing in china status mode issues and countermeasures abstract with the support of national policies china s renewable energy generation industry has experienced a rapid development period and entered the world forefront level especially in the aspects of installed capacity and speed of newly installed capacity however with the rapid development of renewable energy the power generation industry is facing more and more challenges particularly in investment and financing as for wind power industry there are also some problems such as single financing channels blindness of projects investment and so on which will result in financing difficulties for some advanced projects in addition the problems for the investment of photovoltaic pv power generation leads to vicious competition and a tumble in international market thus the overcapacity of china s entire pv industry emerges generally speaking the renewable energy industry is facing a seemingly contradictory predicament of funding deficiencies and blind investment which is derived from the government centered renewable energy investment and financing this government centered mode has promoted the development of renewable energy industry in the early stage but it cannot be adapted to the requirements of sustainable development in view of these the problems of renewable energy investment and financing are deeply studied in this paper this paper proceeds as follows firstly the overview of the development of china s renewable energy industry is briefly introduced secondly the status quo of china s renewable energy investment and financing is explored in detail based on overview of the following five perspectives investment situation investment and financing bodies investment and financing means sources of funding and financing channels secondly the patterns and characteristics of renewable energy financing are summarized and a comparative analysis of wind power and photovoltaic power generation financing means is carried out finally renewable energy investment and financing issues are discussed and further feasible proposals are put forward in all this paper is of great significance in the sustainable and healthy development of china s renewable energy

why did the incumbency advantage in u s house elections grow theory a simple rational entry argument suggests that the value of incumbency consists not just of a direct effect reflecting the value of resources such as staff attached to legislative office but also of an indirect effect reflecting the fact that stronger challengers are less likely to contest incumbent held seats the indirect effect is the product of a scare off effect the ability of incumbents to scare off high quality challengers and a quality effect reflecting how much electoral advantage a party accrues when it has an experienced rather than an inexperienced candidate hypothesis the growth of the overall incumbency advantage was driven principally by increases in the quality effect methods we use a simple two equation model estimated by ordinary least squares regression to analyze u s house election data from 1948 to 1990 results most of the increase in the incumbency advantage at least down to 1980 came through increases in the quality effect i e the advantage to the incumbent party of having a low quality challenger this suggests that the task for those wishing to explain the growth in the vote denominated incumbency advantage is to explain why the quality effect grew it also suggests that resource based explanations of the growth in the incumbency advantage cannot provide a full explanation

compliance choice analysis for india s thermal power sector in the market based energy efficiency regime abstract india has recently introduced a market based scheme perform achieve and trade to realize emission reduction by enhancing energy efficiency in the case of thermal power plants investment in energy efficiency projects using clean coal and buying energy saving certificates are the available compliance options for complying with the scheme these options are associated with specific forms of cash flows that depend on the uncertain price of energy saving certificates and clean coal premium this paper uses a monte carlo based decision tree approach to find the optimal compliance options for an efficient and a less efficient thermal power plant the decision tree evaluates different sequences of compliance options in three consecutive pat cycles by using the discounted cash flows and their associated probabilities the study shows that investment in energy efficiency is optimal in the first pat cycle for the inefficient plant only the threshold certificate price for the efficient plant is substantially higher than the inefficient plant implying that the real efficiency improvement is likely to take place in the low efficiency plants the study also indicates that the investment in high efficiency plants is not optimal over a wide range of certificate prices and the incremental cost of clean coal

time dependent opportunities in energy business a comparative study of locally available renewable and conventional fuels this work investigates and compares energy related private business strategies potentially interesting for investors willing to exploit either local biomass sources or strategic conventional fuels two distinct fuels and related power production technologies are compared as a case study in terms of economic efficiency the biomass of cotton stalks and the natural gas the carbon capture and storage option are also investigated for power plants based on both fuel types the model used in this study investigates important economic aspects using a real options method instead of traditional discounted cash flow techniques as it might handle in a more effective way the problems arising from the stochastic nature of significant cash flow contributors evolution like electricity fuel and co2 allowance prices the capital costs have also a functional relationship with time thus providing an additional reason for implementing real options as well as the learning curves technique the methodology as well as the results presented in this work may lead to interesting conclusions and affect potential private investment strategies and future decision making this study indicates that both technologies lead to positive investment yields with the natural gas being more profitable for the case study examined while the carbon capture and storage does not seem to be cost efficient with the current co2 allowance prices furthermore low interest rates might encourage potential investors to wait before actualising their business plans while higher interest rates favor immediate investment decisions

the effect of candidate quality on electoral equilibrium an experimental study when two candidates of different quality compete in a one dimensional policy space the equilibrium outcomes are asymmetric and do not correspond to the median there are three main effects first the better candidate adopts more centrist policies than the worse candidate second the equilibrium is statistical in the sense that it predicts a probability distribution of outcomes rather than a single degenerate outcome third the equilibrium varies systematically with the level of uncertainty about the location of the median voter we test these three predictions using laboratory experiments and find strong support for all three we also observe some biases and show that they can be explained by quantal response equilibrium

candidate quality the personal vote and the incumbency advantage in congress most political observers agree that incumbent legislators have a considerable advantage over nonincumbents in modern congressional elections yet there is still disagreement over the exact source of this advantage and the explanation for its growth over time to address this debate we utilize a unique set of historical elections data to test for the presence of an incumbency advantage in late nineteenth century house elections 1872 1900 we find a modest direct effect of incumbency and a substantial candidate quality effect moreover the cartel like control of ballot access by nineteenth century political parties created competition in races that the modern market like system simply does not sustain our results suggest that candidate quality is a fundamental piece of the puzzle in understanding the historical development of the incumbency advantage in american politics

emissions trading and investment decisions in the power sector a case study in finland abstract organizations which consider investment in or divestment of power production licences capacity within the european community are exposed to the impacts of the european union emission allowance trading scheme eu ets in this paper the consequences of the eu ets on investment decisions are explored in a country specific setting in finland first we review the general mechanisms through which the eu ets influences size timing and cashflows of an investment next we discuss the projected changes in finnish power producers investment environment and examine the financial impacts due to the eu ets on a case investment decision a hypothetical condensing power plant 250 mwe the standard discounted cash flow dcf analysis is extended to take into account the value of two real options the option to wait and the option to alter operating scale in a quantitative investment appraisal the impact of emissions trading not only depends on the expected level of allowance prices but also on their volatility and correlation with electricity and fuel prices the case study shows that the uncertainty regarding the allocation of emission allowances is critical in a quantitative investment appraisal of fossil fuel fired power plants

estimating incumbency advantage without bias in this paper we prove theoretically and demonstrate empirically that all existing measures of incumbency advantage in the congressional elections literature are biased or inconsistent we then provide an unbiased estimator based on a very simple linear regression model we apply this new method to congressional elections since 1900 providing the first evidence of a positive incumbency advantage in the first half of the century incumbency advantage is the most frequently studied factor in the last 15 years of congressional elections research discovery of the increase in incum bency advantage has sparked controversy over its origins historical pattern cur rent magnitude and electoral democratic and policy consequences even the most basic descriptive information about incumbency advantage is flawed be cause every previous measure based on aggregate data in this literature is plagued by selection bias inconsistencies and inefficiencies we prove this result and also propose a new unbiased and statistically efficient measure that is very easy to calculate congressional elections from 1900 to the present fit our theoretical model our empirical reanalyses do not challenge the existing scholarly consen sus that incumbency advantage is much larger than it once was however we do challenge the prevailing belief that incumbency advantage was nonexistent and the evidence that it was negative in house elections during the first half of this century alford and brady 1988 we show instead that the average advantage of incumbency in these elections was about two percentage points in section 1 of this paper we define incumbency advantage and section 2 gives an intuitive sense of the problems identifying it even in ideal electoral sys tems section 3 formally proves that sophomore surge and retirement slump are biased estimates of incumbency advantage and section 4 briefly reveals the flaws

field experiments testing the impact of radio advertisements on electoral competition results from previous studies of campaign spending imply that equal sized grants to both incumbents and challengers are a net benefit to challengers who on average spend less money and derive greater marginal returns from each additional dollar this study provides an experimental test of this proposition cities holding mayoral elections in november 2005 and 2006 were randomly assigned to broadcast nonpartisan radio ads that stated the names of the mayoral candidates reminded listeners about the date of the upcoming election and encouraged them to vote consistent with the findings of previous studies on the differential effects of incumbent and challenger campaign spending on election outcomes we find that these radio ads produced substantially more competitive elections the borderline statistical significance of our results however invites replication of this experiment

stick to the fundamentals and discover your peers the use of industry as a criterion for selecting peers for multiples based valuation rests on the notion that companies operating in the same industry are more likely to share fundamental value drivers i e profitability growth and risk however such companies may not have similar characteristics in terms of these drivers and thus should not be traded at the same multiple we analyze this issue by developing the sum of absolute rank differences sard approach the sard approach can account for an infinite number of proxies for profitability growth and risk while remaining independent of industry classifications our results indicate that the sard approach yields significantly more accurate valuation estimates than the industry classification approach

the glass ceiling in politics formalization and empirical tests there is a scarcity of women at the apex of political power as well as a lack of methods to disentangle the potential sources of this under representation this article suggests a four step method to test for whether women s under representation can be explained by the existence of a glass ceiling we emphasize that this concept implies discrimination in promotions within the political organization that the discriminatory promotions increase in severity at the top levels of power and that they increase in severity during an individual s career trajectory the proposed method is applied to subnational politics in sweden a long standing world leader in women s descriptive representation the results support the conjecture that a glass ceiling is hindering elected women s rise to political power in this context

explaining patterns of candidate competition in congressional elections the low probability of defeating incumbent members of congress deters potentially strong rivals from challenging them yet almost all incumbents are challenged usually by opponents who lack previous experience in office and run underfinanced ineffectual campaigns but if strong challengers are deterred from challenging incumbents why are not weak challengers who have even less chance of unseating an incumbent the model developed in this paper indicates that there is a simple reason why weak candidates choose to run against incumbents they do so in order to maximize their probability of getting elected to congress together with the findings of previous researchers the results of our analyses of congressional primary data from 1980 through 1984 provide strong support for the major hypotheses derived from our model

carbon capture and storage investment strategies for the future abstract the following article deals with real options modeling for investing into carbon capture and storage technologies herein we derive two separate models the first model incorporates a constant convenience yield and dividend for the investment project in the second model the convenience yield is allowed to follow a mean reverting process which seems to be more realistic but also increases the model s complexity both frameworks are to be solved numerically therefore we calibrate our model with respect to empirical data and provide insights into the models sensitivity toward the chosen parameter values we found that given the recently observable prices for carbon dioxide an investment into c o2 storage facilities is not profitable

applying real options in investment decisions relating to environmental pollution abstract this study focuses on how to assess the optimal environmental investment decisions under economic and ecological uncertainty and establishes the continuous time model using the real option approach to optimize environmental pollution policy unlike traditional cost benefit analysis this work extends the model of pindyck r s 2002 optimal timing problems in environmental economics journal of economic dynamics and control 26 9 10 1677 1697 and attempts to identify the storage threshold of pollution stocks and the optimal timing for implementing environmental pollution decisions

a cost benefit analysis of generating electricity from biomass abstract a key challenge internationally is the design of future electricity systems which will bring about emissions savings and fuel security at least cost peat is used to generate electricity in several eu countries mainly to take advantage of indigenous resources and increase fuel mix diversity the irish government has introduced a target of 30 cofiring of peat and biomass by 2015 this paper assesses the feasibility of achieving this target by calculating the available indigenous biomass resource capable of being cofired the cost of meeting the target the benefits in terms of carbon abatement and finally the present value in economic terms of meeting the target results demonstrate that ireland has only half the necessary resource to meet the 30 target and that the net cost of doing so is greater than the cost of what is currently being paid for peat in all of the scenarios considered thus it is concluded that while it may be technically possible to meet the target by combining national resources with imported biomass this is never the least cost option and as a result the targeted focus of government policy may need to be reconsidered

estimating the price of tradable permits for greenhouse gas emissions in 2008 12 abstract many attempts have been made recently to predict the prices of tradable permits for greenhouse gas ghg emissions in the first commitment period of the kyoto protocol 2008 12 in this paper we attempt to refine these price estimates based on i the results of economic models and identification of factors which influence prices but are not fully reflected in the models ii lessons from price forecasting experience in the us sulfur dioxide market and iii current price data from the nascent international market for ghg permits we expect ghg permit prices to be at the lower end of the broad spectrum of existing predictions this implies among other things that resource transfers to developing countries associated with emissions trading will be relatively low nevertheless even a modest price will have a significant influence on the decisions of consumers and investors in energy markets around the world

electoral contributions and the cost of unpopularity when considering electoral campaigns candidates receiving contributions from relatively unpopular industries should be regarded less favorably by voters that have information on the sources of funding to offset this unpopularity effect politicians may either demand more money for campaign advertising from these industries in order to persuade less informed voters or shy away from unpopular contributors to avoid losing the support of the informed electorate our model predicts that the first effect dominates and electoral contributions are increasing in industry unpopularity by using u s house elections data and different identification strategies we provide robust evidence in favor of our predictions jel d72 p16

an intertemporal general equilibrium model of asset prices this paper develops a continuous time general equilibrium model of a simple but complete economy and uses it to examine the behavior of asset prices in this model asset prices and their stochastic properties are determined endogenously one principal result is a partial differential equation which asset prices must satisfy the solution of this equation gives the equilibrium price of any asset in terms of the underlying real variables in the economy in this paper we develop a general equilibrium asset pricing model for use in applied research an important feature of the model is its integration of real and financial markets among other things the model endogenously determines the stochastic process followed by the equilibrium price of any financial asset and shows how this process depends on the underlying real variables the model is fully consistent with rational expectations and maximizing behavior on the part of all agents our framework is general enough to include many of the fundamental forces affecting asset markets yet it is tractable enough to be specialized easily to produce specific testable results furthermore the model can be extended in a number of straightforward ways consequently it is well suited to a wide variety of applications for example in a companion paper cox ingersoll and ross 7 we use the model to develop a theory of the term structure of interest rates many studies have been concerned with various aspects of asset pricing under uncertainty the most relevant to our work are the important papers on intertemporal asset pricing by merton 19 and lucas 16 working in a continuous time framework merton derives a relationship among the equilibrium expected rates of return on assets he shows that when investment opportunities are changing randomly over time this relationship will include effects which have no analogue in a static one period model lucas considers an economy with homogeneous individuals and a single consumption good which is produced by a number of processes the random output of these processes is exogenously determined and perishable assets are defined as claims to all or a part of the output of a process and the equilibrium determines the asset prices our theory draws on some elements of both of these papers like merton we formulate our model in continuous time and make full use of the analytical tractability that this affords the economic structure of our model is somewhat similar to that of lucas however we include both endogenous production and

designing monetary policy committees we integrate monetary policy making by committee into a new keynesian model to assess the consequences of the committee s institutional characteristics for inflation output and welfare our analysis delivers the following results first we demonstrate that transparency about the committee s future composition is typically harmful second we show that short terms for central bankers lead to effective inflation stabilization at the expense of comparably high output variability third larger committees generally allow for more efficient stabilization of inflation but possibly for less efficient output stabilization fourth large committees and short terms are therefore socially desirable if the weight on output stabilization in the social loss function is low fifth we show that a central banker with random preferences may be preferable to a central banker who shares the preferences of society

the quality of political institutions and the curse of natural resources we propose a theoretical model to explain empirical regularities related to the curse of natural resources which emphasises the behaviour and incentives of politicians we extend the standard voting model to give voters political control beyond the elections this gives rise to a new restriction that policies should not give rise to a revolution our model clarifies when resource discoveries might lead to revolutions namely in countries with weak institutions it also suggests that for bad political institutions human capital depends negatively on natural resources while for high institutional quality the dependence is reversed this finding is corroborated in cross section regressions

a real options evaluation model for the diffusion prospects of new renewable power generation technologies this study presents a policy planning model that integrates learning curve information on renewable power generation technologies into a dynamic programming formulation featuring real options analysis the model recursively evaluates a set of investment alternatives on a year by year basis thereby taking into account that the flexibility to delay an irreversible investment expenditure can profoundly affect the diffusion prospects of renewable power generation technologies price uncertainty is introduced through stochastic processes for the average wholesale price of electricity and for input fuel prices demand for electricity is assumed to be increasingly price sensitive as the electricity market deregulation proceeds reflecting new options of consumers to react to electricity price changes such as time of use pricing unbundled electricity services and choice of supplier the empirical analysis is based on data for the turkish electricity supply industry apart from general implications for policy making it provides some interesting insights about the impact of uncertainty and technical change on the diffusion of various emerging renewable energy technologies

short term generation asset valuation a real options approach this paper discusses using real options to value power plants with unit commitment constraints over a short term period we formulate the problem as a multistage stochastic problem and propose a solution procedure that integrates forward moving monte carlo simulation with backward moving dynamic programming we assume that the power plant operator maximizes expected profit by deciding in each hour whether or not to run the unit that a certain lead time for commitment and decommitment decisions is necessary to start up and shut down a unit and that these commitment decisions once made are subject to physical constraints such as minimum uptime and downtime we also account for the costs associated with starting up and shutting down a unit last we assume that there are hourly markets for both electricity and the fuel used by the generator and that their prices follow ito processes using numerical simulation we show that failure to consider physical constraints may significantly overvalue a power plant

renewable energy investments under different support schemes a real options approach abstract this paper adopts a real options approach to analyze investment timing and capacity choice for renewable energy projects under different support schemes the main purpose is to examine investment behavior under the most extensively employed support schemes namely feed in tariffs and renewable energy certificate trading we consider both multiple sources of uncertainty under each support scheme and uncertainty with respect to any change of support scheme and we obtain both analytical when possible and numerical solutions in a nordic case study based on wind power we find that the feed in tariff encourages earlier investment nevertheless as investment has been undertaken renewable energy certificate trading creates incentives for larger projects in our baseline scenario and taking the fixed feed in tariff as a base the revenue required to trigger investments is 61 higher with renewable certificates at the same time investment capacity is 61 higher

european co2 prices and carbon capture investments we assess the option to install a carbon capture and storage ccs unit in a coal fired power plant operating in a carbon constrained environment we consider two sources of risk namely the price of emission allowance and the price of the electricity output first we analyse the performance of the eu market for co2 emission allowances specifically we focus on the contracts maturing in the kyoto protocol s first commitment period 2008 to 2012 and calibrate the underlying parameters of the allowance price process then we refer to the spanish wholesale electricity market and calibrate the parameters of the electricity price process we use a two dimensional binomial lattice to derive the optimal investment rule in particular we obtain the trigger allowance prices above which it is optimal to install the capture unit immediately we further analyse the effect of changes in several variables on these critical prices among them allowance price volatility and a hypothetical government subsidy we conclude that at current permit prices immediate installation does not seem justified from a financial point of view this need not be the case though if carbon market parameters change dramatically carbon capture technology undergoes significant improvements and or a specific governmental policy to promote these units is adopted

what s a losing party to do the calculus of contesting state legislative elections existing theories of contesting elections typically treat all potential challengers as identical while under playing the importance of political parties and primary contests we offer a theory addressing these issues based on how the various actors in the process define and evaluate the probability of winning an election and the value of the office being contested we test our theory by estimating a model predicting which of three responses a party that loses a legislative race makes in the next cycle nominating the same candidate nominating a new candidate or nominating no one we find substantial empirical support for our theory

investments in eop technologies and emissions trading results from a linear programming approach and sensitivity analysis abstract this paper offers a general approach to valuating investments in end of pipe technologies eop technologies with special regard to an emissions trading scheme since investments of this kind affect production it is necessary to derive the required payments for a financial valuation and the constraints from production theory and production planning on this basis it is possible to develop a valuation model this model considers joint production activity level dependent and independent payments and specifically includes the indivisibility of the investment applying duality theory enables us to examine the determinants of the price ceiling for such an investment sensitivity analysis shows that tradable permits have several effects on an investment and do not always encourage environmentally beneficial investments in particular cases they may even be counterproductive

the impact of campaign spending on votes in multiparty elections abstract the impact of candidate campaign spending on votes and abstention in multiparty elections is estimated from the specification of a structural model of voter behavior this model accounts for the endogeneity of campaign spending as well as the heterogeneity in voter preferences empirical results are estimated from aggregate actual election data the results demonstrate the importance of spending during the campaign period and voter heterogeneity with respect to these expenditures the own and cross expenditure vote share elasticity estimates reveal that political campaign spending not only redistributes voters across parties but also decreases the size of the abstaining group of the electorate

carbon market risks and rewards firm perceptions of cdm investment decisions in brazil and india the carbon market experiences of brazil and india represent policy success stories under several criteria a careful evaluation however reveals challenges to market development that should be addressed in order to make the rollout of a post 2012 cdm more effective we conducted firm level interviews covering 82 cdm plants in the sugar and cement sectors in brazil and india focusing on how individual managers understood the potential benefits and risks of undertaking clean development mechanism cdm investments our results indicate that the cdm operates in a far more complex way in practice than that of simply adding a marginal increment to a project s internal rate of return our results indicate the following first although anticipated revenue played a central role in most managers decisions to pursue cdm investments there was no standard practice to account for financial benefits of cdm investments second some managers identified non financial reputational factors as their primary motivation for pursuing cdm projects and third under fluctuating regulatory regimes with real immediate costs and uncertain cdm revenue managers favored projects that often did not require carbon revenue to be viable the post 2012 cdm architecture can benefit from incorporating these insights and in particular reassess goals for strict additionality and mechanisms for achieving it

investing in finite life carbon emissions reduction program under risk and idiosyncratic uncertainty this paper aims at emphasizing the ability of new frameworks of real option model to highlight key characteristics of industrial carbon emissions reduction program investment decision we develop both theoretical arguments and numerical simulations with structural parameters calibrated on real life data we find that both radical uncertainty and risk lead to speed up green investments compared to the predictions of real option models that are normally used in green investment literature the conventional wait and see attitude questioned in recent developments of the real option theory is not validated in conclusion our results should foster companies to implement green investments and help governments to define appropriate incentives to encourage green investments of particular note the paper highlights that finance theory is not necessarily an obstacle to green investment decisions

classroom games candidate convergence this article details an experiment that is easily run in the classroom it demonstrates how two candidate elections quickly converge to an equilibrium it points out that the equilibrium is centered on the median voter finally it illustrates what happens when preferences or institutions change material associated with conducting the experiment is provided as is supplemental material for classroom instruction a critical part of teaching political economy is getting students to understand the link between voter preferences candidate position taking and vote aggregation rules while in the abstract it is easy to understand that candidates will often converge to the median voter the ease with which candidates respond is not often grasped this exercise mimics multiple elections with candidates holding no information about the distribution of voter preferences parallels are also drawn to one dimensional spatial location models the median voter model is one of the basic building blocks for political economy the model assumes that voters have single peaked preferences over a single policy dimension this means that each voter has a single preferred position that can be mapped onto the policy dimension and the voter s utility decreases as a function of distance from that preferred position candidates seek election by proposing a policy position that will be implemented if elected voters then compare the utility they get from the policy position proposed by each candidate in a two candidate model the median voter s position is in equilibrium and candidates converge to the equilibrium the simplicity of the model and its unique equilibrium allows those teaching various aspects of political economy to quickly cut through the complexity of political elections this classroom experiment has three goals the first is to demonstrate that competitive elections quickly drive candidates to adopt winning positions second the exercise points to the stability of an equilibrium this is especially useful for students who feel that an equilibrium is a fuzzy concept with little explanatory power in this exercise candidates who deviate from the equilibrium are quickly punished third the exercise introduces a feature common to many political systems redistricting this can be thought of as a change in the preferences of some voters simple changes in student

the price of pork the seniority trap in the u s house abstract using data on federal outlays and u s house elections i estimate the effect of the pork barrel on the quality of officeholders taking into account the fact that seniority creates a dynamic linkage across periods after estimating the parameters governing the influence of seniority on federal outlays and the parameters governing the distributions of candidate quality i conduct several policy experiments to uncover the size of the welfare loss created by the seniority system i find that the seniority system negatively impacts the quality of representatives but has little effect on the outcomes of elections furthermore the most commonly proposed solution to the distortion term limits may have a significant negative effect on the quality of sitting representatives instead of a quantity constraint term limits i propose a change in the relative price of seniority by way of a pigouvian tax on seniority such a policy achieves the first best outcome

on the mis measurement of legislator ideology and shirking in this paper we show that current statistical measures of legislator s shirking are implicitly based on the electoral concept of a unique majority rule equilibrium point in the policy space where elections are contested we note that such equilibria do not exist generically and present statistical results showing that cross sectional regressions where legislators voting indices are predicted by district average demograhic and economic data are mis specified we also discuss a weaker equilibrium construct the uncovered set and present statistical evidence showing that differences in voting behavior between senators from the same state are positively related to the heterogeneity of the electorate we argue that current evidence alleged to show shirking by senators is equally consistent with senators who perfectly represent an idiosyncratic constituency that cannot be represented by district average data

price dynamics in the european union emissions trading system and evaluation of its ability to boost emission related investment decisions abstract the price of permits in the european union emissions trading system eu ets has historically been highly sensitive and prone to jumps we consider different stochastic processes to model the price of permits and show that the variance gamma vg model provides the best fit for the price distribution among a selection of infinite activity processes using this result as a starting point we assess the effects of the eu ets in delivering low carbon investments at the firm level by modeling a price taker electricity producer subject to the eu ets jurisdiction we compute via least squares monte carlo the value of the real option the greenhouse gas emitter has consisting in the opportunity to switch from its current high carbon technology to a cleaner one we use a vg specification for carbon prices and a mean reverting brennan schwartz process for the price of fuel moreover we further analyze the investment decision problem in case of a co 2 price stabilization mechanism in the form of a price floor by explicitly computing the expected value of the investment project by means of fourier methods our results show that the introduction of the price stabilization mechanism significantly affects the timing of the investment decision and supports emission related investments

assessing the effects of co2 price caps on electricity investments a real options analysis abstract this paper uses real options modeling to assess the impact of different climate change policy instruments on investment profits and cumulative emissions in the electricity sector even though co 2 price caps or safety valves have been suggested as methods to limit uncertainty emanating from fluctuating prices of co 2 permits that would hurt the industry s profit and thereby also energy security our analysis shows that price caps set at a too low level are detrimental to the adoption of e g modern biomass fired capacity as a replacement for existing coal fired power plants we therefore conduct a series of experiments with different policy scenarios to analyze under which regime emissions are most effectively reduced with respect to co 2 price uncertainty it turns out that even for moderately rising co 2 prices fluctuations frequently lead to investment into carbon capture and storage ccs while investment is often not triggered in the face of deterministic co 2 prices

combining value estimates to increase accuracy the estimates provided by discounted cash flow the method of comparables and market prices usually disagree combining two or more of these value estimates makes sense because every bona fide estimate provides information and because relying on one estimate ignores the information content of the others how then should financial analysts combine different value estimates to form a more accurate estimate than that provided by any one method drawing from bayesian decision theory the delaware block method and forecasting research this article suggests five rules of thumb for combining two or more value estimates into a superior value estimate

political selection and persistence of bad governments we study dynamic selection of governments under different political institutions with a special focus on institutional flexibility a government consists of a subset of the individuals in the society the competence level of the government in office determines collective utilities e g by determining the amount and quality of public goods and each individual derives additional utility from being part of the government e g rents from holding office we characterize the dynamic evolution of governments and determine the structure of stable governments which arise and persist in equilibrium in our model perfect democracy where current members of the government do not have veto power over changes in governments always leads to the emergence of the most competent government however any deviation from perfect democracy to any regime with incumbency veto power destroys this result there is always at least one other less competent government that is also stable and can persist forever and even the least competent government can persist forever in office we also show that there is a nonmonotonic relationship between the degree of incumbency veto power and the quality of government in contrast in the presence of stochastic shocks or changes in the environment a regime with less incumbency veto power has greater flexibility and greater probability that high competence governments will come to power this result suggests that a particular advantage of democratic regimes with a limited number of veto players may be their greater adaptability to changes rather than their performance under given conditions finally we show that royalty like dictatorships may be more successful than junta like dictatorships because in these regimes veto players are less afraid of change

who is my peer a valuation based approach to the selection of comparable firms this study presents a general approach for selecting comparable firms in market based research and equity valuation guided by valuation theory we develop a warranted multiple for each firm and identify peer firms as those having the closest warranted multiple we test this approach by examining the efficacy of the selected comparable firms in predicting future one to three year ahead enterprise value to sales and price to book ratios our tests encompass the general universe of stocks as well as a sub population of so called new economy stocks we conclude that comparable firms selected in this manner offer sharp improvements over comparable firms selected on the basis of other techniques

an electricity generation planning model incorporating demand response abstract energy policies that aim to reduce carbon emissions and change the mix of electricity generation sources such as carbon cap and trade systems and renewable electricity standards can affect not only the source of electricity generation but also the price of electricity and consequently demand we develop an optimization model to determine the lowest cost investment and operation plan for the generating capacity of an electric power system the model incorporates demand response to price change in a case study for a u s state we show the price demand and generation mix implications of a renewable electricity standard and of a carbon cap and trade policy with and without initial free allocation of carbon allowances this study shows that both the demand moderating effects and the generation mix changing effects of the policies can be the sources of carbon emissions reductions and also shows that the share of the sources could differ with different policy designs the case study provides different results when demand elasticity is excluded underscoring the importance of incorporating demand response in the evaluation of electricity generation policies

the information content of losses abstract this study hypothesizes that because shareholders have a liquidation option losses are not expected to perpetuate they are thus less informative than profits about the firm s future prospects the results are consistent with the hypothesis they also show that the documented increase in the earnings response coefficent as the cumulation period increases appears to be due exclusively to the effect of losses the liquidation option effect extends to profitable cases where earnings are low enough to make the option attractive alternating explanations for the low informativeness of losses such as mean reversal of earnings are not supported by the tests

irreversible abatement investment under cost uncertainties tradable emission permits and emissions charges abstract a major concern with tradable emission permits is that stochastic permit prices may reduce a firm s incentive to invest in abatement capital or technologies relative to other policies such as a fixed emissions charge however under efficient permit trading the permit price uncertainty is caused by abatement cost uncertainties which affect investment under both permit and charge policies we develop a rational expectations general equilibrium model of permit trading and irreversible abatement investment to show how cost uncertainties affect investment under permits we compare the resulting investment incentive with that under charges after controlling for the assumption that random shocks affect the abatement cost linearly we find that firms investment incentive decreases in cost uncertainties but more so under emissions charges than under permits therefore tradable permits in fact may help maintain firms investment incentive under uncertainty

the effect of mean reversion on investment under uncertainty abstract mean reverting processes are appropriate for most real option investment models yet geometric brownian motion gbm processes are generally used for tractability hassett and metcalf j econom dyn control 19 1995 1471 1488 argue that using a gbm process is justified because mean reversion has two opposing effects it brings the investment trigger closer and also reduces the conditional volatility thereby lowering the likelihood of reaching the trigger and the overall effect on investment should be negligible for most reasonable parameter values this paper extends the hassett and metcalf model by incorporating a third factor the effect of mean reversion on systematic risk the main result is that mean reversion in general does have a significant impact on investment moreover this effect could be either positive or negative depending on various factors such as project duration cost of investing interest rate etc thus it is generally inappropriate to use the gbm process to approximate a mean reverting process

ecology driven real options an investment framework for incorporating uncertainties in the context of the natural environment the role of uncertainty within an organization s environment features prominently in the business ethics and management literature but how corporate investment decisions should proceed in the face of uncertainties relating to the natural environment is less discussed from the perspective of ecological economics the salience of ecology induced issues challenges management to address new types of uncertainties these pertain to constraints within the natural environment as well as to institutional action aimed at conserving the natural environment we derive six areas of ecology induced uncertainties and propose ecology driven real options as a conceptual approach for systematically incorporating these uncertainties into strategic management we combine our results in an integrative investment framework and illustrate its application with the case of carbon constraints

investment under alternative return assumptions comparing random walks and mean reversion abstract many recent theoretical papers have come under attack for modeling prices as geometric brownian motion this process can diverge over time implying that firms facing this price process can earn infinite profits we explore the significance of this attack and contrast investment under geometric brownian motion with investment assuming mean reversion while analytically more complex mean reversion in many cases is a more plausible assumption allowing for supply responses to increasing prices we show that cumulative investment is generally unaffected by the use of a mean reversion process rather than geometric brownian motion and provide an explanation for this result

do several winning coalitions exist in a state for senators of the same party evidence from an event study we argue that u s senators from the same state and in the same party form different winning coalitions we also develop a theory that stipulates that parties encourage these senators to form very distinct constituency coalitions parties use committee assignments as a carrot to give these senators an incentive to represent different groups in our empirical analysis we find that there are fewer overlapping committee assignments among senators in the same state when they are from the same party we also consider the case of john heinz and arlen specter both pennsylvania republicans when john heinz died in a plane crash political action committees pacs that bought influence from specter but not heinz now had the possibility that the new senator replacing heinz would include them in his resource constituency the resulting competition by the new pennsylvania senator and specter for campaign resources would lower the price these firms had to pay for representation thus improving their expected future earnings

optimisation of electricity energy markets and assessment of co2 trading on their structure a stochastic analysis of the greek power sector power production was traditionally dominated by monopolies after a long period of research and organisational advances in international level electricity markets have been deregulated allowing customers to choose their provider and new producers to compete the former public power companies vast changes have been made in the european legal framework but still the experience gathered is not sufficient to derive safe conclusions regarding the efficiency and reliability of deregulation furthermore emissions trading progressively becomes a reality in many respects compliance with kyoto protocol s targets is a necessity and stability of the national grid s operation is a constraint of vital importance consequently the production of electricity should not rely solely in conventional energy sources neither in renewable ones but on a mixed structure finding this optimal mix is the primary objective of the study a computational tool has been created that simulates and optimises the future electricity generation structure based on existing as well as on emerging technologies the results focus on the greek power sector and indicate a gradual decreasing of anticipated co2 emissions while the socioeconomic constraints and reliability requirements of the system are met policy interventions are pointed out based on the numerical results of the model c 2010 elsevier ltd all rights reserved

when to risk it institutions ambitions and the decision to run for the u s house the health of any democratic system depends on political ambition to generate a steady supply of quality candidates for office because most models of candidate entry assume ambition rather than model it previous research fails to understand its roots in individual and institutional characteristics we develop a two stage model of progressive behavior that distinguishes between the formation of ambition for higher office and the decision to enter a particular race using data from a survey of state legislators we demonstrate that the intrinsic costs and benefits associated with running for and holding higher office shape ambitions but do not influence the decision to run for progressively ambitious legislators the second stage decision is a strategic choice about when to run rather than whether to run our research highlights how institutional characteristics that foster progressive ambition also increase the likelihood that national or local political conditions will be translated into meaningful choices at the ballot box

market in efficiency in valuing electric utilities the case of norwegian generating companies after deregulation of the energy market in norway a number of mergers and acquisitions of hydropower generating companies have taken place however valuation of these companies has proved controversial from an ex post perspective there is support for the criticism that generation assets have been sold too cheaply this article presents a simple valuation model providing evidence of how value has evolved on the basis of these results we discuss the valuation from an ex ante perspective and in the light of the market efficiency hypothesis of fama 1970 1991

candidate uncertainty mental models and complexity some experimental results since the work of downs 1957 spatial models of elections have been a mainstay of research in political science and public choice despite the plethora of theoretical and empirical research involving spatial models researchers have not considered in great detail the complexity of the decision task that a candidate confronts two facets of a candidate s decision process are investigated here using a set of laboratory experiments where subjects face a fixed incumbent in a two dimensional policy space first we analyze the effect that the complexity of the electoral landscape has on the ability of the subject to defeat the incumbent second we analyze the impact that a subject s mental model which we infer from a pre experiment questionnaire has on her performance the experimental results suggest that the complexity of a candidate s decision task and her perception of the task may be important factors in electoral competition

district complexity as an advantage in congressional elections scholars of congressional elections have argued that an increase in constituent diversity increases the level of electoral competition following models of boundedly rational candidates we argue that there is strong reason to believe that the opposite is true as the complexity of the electoral landscape increases challengers will have a more difficult time locating an optimal platform when facing an experienced incumbent using data from the 2000 national annenberg election study we construct a novel measure of district complexity for u s house districts and test whether the entry of quality challengers and the incumbent s share of the two party vote are affected by the complexity of the electoral landscape we find strong support for the hypothesis that complexity benefits incumbents for both indicators of electoral competition which stands in contrast to most of the existing literature on diversity and incumbent performance

impact of a possible environmental externalities internalisation on energy prices the case of the greenhouse gases from the greek electricity sector the present paper is concerned with the impact of the internalisation of environmental externalities on energy prices in this context its aim is to quantify the external cost of greenhouse gases specifically carbon dioxide generated during electricity production in the thermal power plants in greece and to estimate the impact on the electricity production cost and on the electricity prices of a possible internalisation of this external cost by the producers for this purpose this paper applies the ecosensele online tool to quantify the examined externalities this research finds that the calculated external cost is significantly high compared to the corresponding production cost mainly in lignite fired power plants specifically a possible internalisation of this external cost would increase the production cost by more than 52 on average which in turn would affect similarly the electricity prices this finding could be important for decision makers in the electricity sector to develop strategies for emission reduction and to develop environmental and energy policies the general limitation of the external cost methodology applies to this work as it uses the standard method developed for the externe project similarly the data limitations as well as assumptions related to the costs and exclusions omissions of cost elements affect the results

the use of real options approach in energy sector investments abstract energy shortage global warming and climate change led to an increase in the use of alternative sources of energy with renewable energy sources res playing a fundamental role in this new energetic paradigm however the investment costs often constitute a major barrier to their spread use moreover the overall benefits of renewable energy technologies are often not well understood and consequently they are often evaluated to be not as cost effective as traditional technologies from the moment that the energy sector started a deregulation process with a high level of competitiveness and associated increased market uncertainty traditional project evaluation techniques alone became insufficient to properly deal with these additional risk and uncertainty factors the diffusion of the renewable energy technologies is also affected by this feature the way investors evaluate their investments call now for the use of more sophisticated evaluation techniques real options approach can deal with these issues and as so began to be considered and applied for the energy sector decision aid this approach it is now extensively widespread in evaluating investment projects in the energy sector a large set of applications in almost all fields of energy decision making from electricity generation technologies appraisal to policy evaluation is available in the literature however the use of this technique in the field of res is still limited and worth to be analysed this paper addresses this issue a review of the current state of the art in the application of real options approach to investments in non renewable energy sources and res is presented giving perspectives for further research in this field

do voters affect or elect policies evidence from the u s house there are two fundamentally different views of the role of elections in policy formation in one view voters can affect candidates policy choices competition for votes induces politicians to move toward the center in this view elections have the effect of bringing about some degree of policy compromise in the alternative view voters merely elect policies politicians cannot make credible promises to moderate their policies and elections are merely a means to decide which one of two opposing policy views will be implemented we assess which of these contrasting perspectives is more empirically relevant for the u s house focusing on elections decided by a narrow margin allows us to generate quasi experimental estimates of the impact of a randomized change in electoral strength on subsequent representatives roll call voting records we find that voters merely elect policies the degree of electoral strength has no effect on a legislator s voting behavior for example a large exogenous increase in electoral strength for the democratic party in a district does not result in shifting both parties nominees to the left politicians inability to credibly commit to a compromise appears to dominate any competition induced convergence in policy

quality counts extending the strategic politician model of incumbent deterrence competitive elections are essential to representative democracy competition in u s house elections is low in part because incumbents have strategic advantages that deter strong potential candidates from running many observers conclude that incumbents retain their seats without full accountability to the electorate but the mechanisms of deterrence have never been fully explored from the perspective of strong potential candidates based on a survey of potential house candidates designed to capture perceptions of incumbents personal quality and reelection prospects we find strong evidence for the strategic politicians thesis black 1972 jacobson and kernell 1983 we extend the logic of the strategic model first by showing that incumbents reelection prospects are affected by their personal quality and second by demonstrating that incumbents personal qualities deter strong challengers from running independent of their electoral prospects our findings prompt us to suggest revisions to our understanding of competition and representation in contemporary house elections

using multimember district elections to estimate the sources of the incumbency advantage in this article we use a novel research design that exploits unique features of multimember districts to estimate and decompose the incumbency advantage in state legislative elections like some existing related studies we also use repeated observations on the same candidates to account for unobserved factors that remain constant across observations multimember districts have the additional feature of copartisans competing for multiple seats within the same district this allows us to identify both the direct office holder benefits and the incumbent quality advantage over nonincumbent candidates from the same party we find that the overall incumbency advantage is of similar magnitude as that found in previous studies we attribute approximately half of this advantage to incumbents quality advantage over open seat candidates and the remainder to direct office holder benefits however we also find some evidence that direct office holder benefits are larger in competitive districts than in safe districts and in states with relatively large legislative budgets per capita

estimating the effect of campaign spending on senate election outcomes using instrumental variables o examine the traditional view that challenger spending is more effective than incumbent spending 7 i reestimate the effects of spending using instrumental variables that affect a candidate s ability to raise campaign funds such as candidate wealth levels hhen the endogeneity of candidate spending levels is properly taken into account the marginal effects of incumbent and challenger spending are roughly equal in contrast to previous research showing that because of higher marginal returns to challenger spending the incumbent s spending advantage cannot explain high incumbent reelection rates this article shows that in an average senate election the incumbent s spending advantage yields a 6 increase in the incumbent s vote share that incumbent spending wins elections has direct implications regarding the consequences of campaign finance reform my findings imply that equalizing spending levels may significantly increase incumbent defeat rates and caps on candidate spending may improve the chances of challengers in american congressional elections incumbents routinely win reelection even in the 1994 republican landslide change in the partisan makeup of congress occurred mainly through open seats switching from the democrats to the republicans a common explanation for high congressional reelection rates is the large campaign spending advantage enjoyed by incumbents it is widely believed that challenger spending is very important but there is surprisingly little evidence in the academic literature that incumbent campaign spending has an important effect on congressional election outcomes in light of the substantial effort incumbents devote to fundraising as well as some nagging methodological questions about existing academic studies the effect of incumbent spending on election outcomes remains an unresolved issue accurately measuring how incumbent spending leads to votes is of obvious importance politicians want to win elections and so if money matters then this will influence their behavior if campaign spending effects are trivial then concerns about politicians being

integration of ccs emissions trading and volatilities of fuel prices into sustainable energy planning and its robust optimization in this paper a new approach has been proposed that allows a robust optimization of sustainable energy planning over a period of years it is based on the modified energy flow optimization model efom and minimizes total costs in planning capacities of power plants and ccs to be added stripped or retrofitted in the process it reduces risks due to a high volatility in fuel prices it also provides robustness against infeasibility with respect to meeting the required emission level by adopting a penalty constant that corresponds to the price level of emission allowances in this manner the proposed methodology enables decision makers to determine the optimal capacities of power plants and or ccs as well as volumes of emissions trading in the future that will meet the required emission level and satisfy energy demand from various user sections with minimum costs and maximum robustness they can also gain valuable insights on the effects that the price of emission allowances has on the competitiveness of res and ccs technologies it may be used in for example setting appropriate subsidies and tax policies for promoting greater use of these technologies the proposed methodology is applied to a case based on directions and volumes of energy flows in south korea during the year 2008

the clean development mechanism stochastic permit prices and energy investments abstract we analyze the impact on energy investments stemming from different emission permit classes by considering permits that are allocated inside the european emission trading scheme and secondary certified emission reduction scer permits originating from the clean development mechanism one price taking firm which is subject to emission regulation has the choice to invest in gas or wind power plant the firm faces uncertainty regarding stochastically evolving permit prices while it receives a premium on the electricity price for wind energy as a first step we determine the value of the option to invest into a gas power plant over time then we calculate the investment probability of a gas power investment in a range of policy scenarios we find that allowing the usage of scer permits in the present policy framework has a positive impact on gas power investment decoupling the price processes has a similar effect if the quota of scer permits is doubled the decrease in the investment probability for wind power is large we carry out sensitivity tests for different parameter values and find that investment behavior changes significantly with differing interest rates the wind energy premium and volatility

incumbent challenger and open seat elections in a spatial model of political competition in groseclose am j political sci 45 862 886 2001 candidates with asymmetric valence scores and varying degrees of policy motivation simultaneously choose divergent policies i take a version of the groseclose model with policy motivated candidates and extend it to allow for sequential policy announcements this may be a suitable approach for incumbent challenger elections because the incumbent s policy is typically known before the challenger s i show that policy divergence is greater when candidates announce policies sequentially as opposed to simultaneously i also show that policy motivated incumbents benefit from a first mover advantage

climbing the ranks incumbency effects in party list systems abstract incumbents tend to have a solid electoral advantage in candidate centered electoral settings do similar incumbency effects exist in more party centered environments we estimate incumbency effects in an open list proportional representation system exploiting that seats are first allocated across parties and then to candidates within party lists using data from norwegian local elections 2003 2015 we document that a candidate that barely wins a seat in the local council has about a 9 percentage points 43 higher probability of being elected in the next election compared to a candidate that just misses out on a seat on the same party list we find no evidence that voters contribute to this personal incumbency advantage rather it seems as if party elites are instrumental in securing the electoral success of their party affiliates we show that incumbents and non incumbents run again in the subsequent election at about equal rates but that incumbents tend to advance in the party hierarchy and obtain safer ballot positions in future elections which is what ultimately leads to electoral success

challenger entry and voter learning we develop a model of strategic interaction between voters and potential electoral challengers to sitting incumbents in which the very fact of a costly challenge conveys relevant information to voters given incumbent failure in office challenger entry is more likely but the threat of entry by inferior challengers creates an incentive for citizens to become more politically informed at the same time challenges to incumbents who perform well can neutralize a voter s positive assessment of incumbent qualifications how a voter becomes politically informed can in turn deter challengers of different levels of competence from running depending on the electoral environment the model permits us to sharpen our understanding of retrospective voting the incumbency advantage and the relationship between electoral competition and voter welfare while pointing to new interpretations of and future avenues for empirical research on elections

the disadvantaged incumbents estimating incumbency effects in indian state legislatures this paper estimates the incumbency effects using a large dataset on state legislative elections in india during 1975 2003 i use a regression discontinuity design rdd that estimates the causal effect of incumbency by comparing candidates in closely fought elections i find that there is a significant disadvantage to incumbency in indian state legislative elections and the adverse effect of incumbency has increased after 1991 also the incumbency disadvantage is higher in states that have lower availability of public goods such as health centers and lower employment poverty and per capita income

a reform dilemma in polarized democracies abstract we study the feasibility and efficiency of policy reforms in democracies we develop a simple election model where i reforms are costly for voters and politicians and these costs increase with the extent of policy change and ii politicians differ in their ability to carry out reforms efficiently we identify a so called reform dilemma which manifests itself in two variants from a static perspective low reform ability politicians are elected when political parties are polarized who then impose high costs on citizens for each reform step this property of elections arises as low reform ability is a substitute for policy commitment from a dynamic perspective incumbents may choose socially undesirable policies to align the social need for reform with their own reform ability and are thus re elected regardless of their reform ability

how emission certificate allocations distort fossil investments the german example despite political activities to foster a low carbon energy transition germany currently sees a considerable number of new coal power plants being added to its power mix there are several possible drivers for this dash for coal but it is widely accepted that windfall profits gained through free allocation of ets certificates play an important role yet the quantification of allocation related investment distortions has been limited to back of the envelope calculations and stylized models so far we close this gap with a numerical model integrating both germany s particular allocation rules and its specific power generation structure we find that technology specific new entrant provisions have substantially increased incentives to invest in hard coal plants red to natural gas at the time of the ets onset more precisely disproportionate windfall profits compared more than half the total capital costs of a hard coal plant moreover shorter periods of free allocations would not have turned investors favours towards the cleaner natural gas technology because of pre existing economic advantages for coal in contrast full auctioning of permits or a single best available technology benchmark would have made natural gas the predominant technology of choice

emission trading under the kyoto protocol effects on fossil fuel markets under alternative regimes abstract the consequences of the kyoto protocol for the fossil fuel markets depend on which policy instruments are used in order to reach the emission targets this paper uses a numerical model to assess the significance of international emissions trading for the oil coal and gas markets three different trading regimes are compared particular attention is devoted to the eu proposal about limits on acquisitions and transfers of emission permits we find that the eu proposal will be non binding for buyers of emission permits but will significantly constrain the sale of emission permits from eastern europe the eu proposal will increase the level of abatement in annex b countries and will cause a sharp increase in the price of permits compared to the free trade equilibrium

impact of climate policy uncertainty on the adoption of electricity generating technologies this paper presents a real options model where multiple options are evaluated simultaneously so that the effect of the individual options on each other is accounted for we apply this model to the electricity sector where we analyze three typical technologies based on fossil fuel fossil fuel with carbon capture and renewable energy respectively in this way we can analyze the transition from co2 intensive to co2 neutral electricity production in the face of rising and uncertain co2 prices in addition such a modelling approach enables us to estimate precisely the expected value of perfect information i e the willingness of investors and producers to pay for information about the correct co2 price path as can be expected the expected value of information rises with increasing co2 price uncertainty in addition the larger the price uncertainty the larger are the cumulative co2 emissions over the coming century the reason for this is that the transition to less co2 intensive technologies is increasingly postponed with rising co2 price uncertainty by testing different price processes geometric brownian motion versus jump processes with different jump frequencies we can also make useful recommendations concerning the importance of policy predictability we find that it is better to have climate change policies that are stable over a certain length of time and change abruptly than less abrupt but more frequently changing policies less frequent fluctuations reduce the expected value of information and result in smaller cumulative co2 emissions
