pathways to a low carbon economy estimations on macroeconomic costs and potential of carbon emission abatement in beijing abstract developing reliable frameworks to estimate the potential of co2 emission abatement and its associated costs merits urgent attention this study aims to estimate the potential as well as macroeconomic costs of co2 emission abatement in beijing using the industrial economy as the basis multiobjective programming and genetic algorithm are integrated into the input output analysis several important findings have been gathered in the study 1 the abatement cost varies between 259 97 and 535 46 per ton at different rates of economic growth 2 a reinforced emission abatement target can induce higher macroeconomic costs 3 an inverse u shaped relationship between co2 reduction cost and gdp growth rate was found when gdp growth rate is above the threshold value of 7 marginal abatement costs decrease rapidly in parallel with gdp growth when the gdp growth rate is below 7 the marginal abatement cost increases significantly with economic growth 4 industries that have the highest and least potential of abatement have been identified for effectively reducing co2 emissions beijing needs to promote economic restructuring to maximize the potential of emission abatement and also fulfil the emission abatement target in a cost effective way this paper provides a quantitative approach to rationalize the policy design process of enacting emission targets and recommends cost effective abatement strategies

informational constraints and the overlapping generations model folk and anti folk theorems this paper analyses the sustainability of inter generational transfers in samuelson s consumption loan model when agents are imperfectly informed about past events we find that with mild informational constraints transfers cannot be supported by pure strategy equilibria mixed strategies allow transfers to be sustained even if agents have little information so that a version of the folk theorem holds however these equilibria are not robust if each agent s utility function is subjected to a small random perturbation as in harsanyi 1973 these mixed strategy equilibria unravel and only the zero transfer allocation survives as the unique rationalizable outcome this result is an example of mixed strategy equilibrium of an extensive form game which cannot be purified

the innovation impact of the eu emission trading system findings of company case studies in the german power sector abstract this paper provides a detailed analysis of how the european emission trading system eu ets as the core climate policy instrument of the european union has impacted innovation towards this end we investigate the impact of the eu ets on research development and demonstration rd d adoption and organizational change in doing so we pay particular attention to the relative influences of context factors policy mix market factors and public acceptance and firm characteristics value chain position technology portfolio size and vision empirically our qualitative analysis is based on multiple case studies with 19 power generators technology providers and project developers in the german power sector which were conducted in 2008 09 we find that the innovation impact of the eu ets has remained limited so far because of the scheme s initial lack of stringency and predictability and the relatively greater importance of context factors additionally the impact varies significantly across technologies firms and innovation dimensions and is most pronounced for rd d on carbon capture technologies and organizational changes our analysis suggests that the eu ets on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long term targets can be achieved

reverse importing and asymmetric trade and fdi a networks explanation abstract this paper considers the impact of business and social networks on international trade and fdi i propose that differences in the strength of network effects across countries can produce asymmetric trade and investment flows that may lead to trade friction a firm from a country with strong network effects has a cost advantage in selling to buyers from its own country this advantage results in lower inward fdi lower total imports but larger volumes of reverse imports into the country with strong network effects the model s predictions match observed asymmetric trade and investment flows that sometimes lead to us japan trade friction

a real options valuation of chinese wind energy technologies for power generation do benefits from the feed in tariffs outweigh costs abstract in order to assess the viability of wind energy projects in china this paper takes a real options approach by accounting for flexibility over deployment of the technology in response to a stochastic non renewable energy cost the difference between the latter and the r d enhanced cost of renewable energy operation may be thought of as a benefit from using wind on the other hand the chinese government provides feed in tariffs to encourage further adoption of wind which should be included as a cost this work thus shows that there is substantial options value to china s wind energy program which is bolstered if the cost of carbon dioxide emissions is internalized moreover by varying the rate of feed in tariffs the model may be used to show plausible ranges for the feed in tariffs which could be a useful policy insight furthermore the study hypothesizes that with the likelihood of renewable energy to replace non renewable energy wind power in china can potentially reduce co2 emissions by approximately 6 4 by 2020 comparing to the 2005 level and highlights the significant role of wind power in china s emission targets and energy security this is a relevant paper especially given the importance of a sustainable energy transition for china more generally using the real options approach from a policy perspective could provide insights about the viability of renewable energy programs and robustness of feed in tariffs rates

profitability of wind energy investments in china using a monte carlo approach for the treatment of uncertainties abstract china is the global leader in terms of installed wind capacity further wind energy development is expected for the next years and decades to meet the continuously increasing electricity demand and the need of using clean domestic energy since 2009 china is divided into four geographical regions each assigned with a different benchmark on grid tariff moreover the existing infrastructures are not equally developed throughout the country making investment decisions more complicated and risky the scope of this paper is to apply an innovative methodology and evaluate the attractiveness of each region for wind energy development by taking into consideration all relevant investment risks such as wind potential wind curtailment access to the grid and macroeconomic parameters to this purpose a monte carlo simulation approach integrated into a typical financial model is implemented in each of the four regions performing many hundreds of iterations each characterized by a randomly selected set of the examined uncertain parameters this approach intends to provide information to private investors doing a first exploratory research in the huge country s area in order to decide whether and where to invest as well as to policy makers to help them assess critical policy parameters and investigate different scenarios of wind energy development the evaluation of the current framework for wind energy development in china verifies that the existing system of feed in tariffs in china is very effective for the balanced deployment of wind energy in the whole country however it is shown that the risk of curtailment and grid accessibility may significantly reduce the potential profitability of wind energy investments in all four regions priority for development of infrastructures should be given in isolated northern windy areas with high accumulation of wind farms

information institutions and constitutional arrangements this paper develops a theory of optimal institutional structure for staggered term overlapping generations organizations such as legislative bodies our model is a simple stochastic game of multi principal multi agent dynamic relationships our results emphasize two key features that are determined by legislative founders at the constitutional moment first they will agree to institute a mechanism that endows imperfectly informed legislators with information about the history of play second we provide conditions in which legislative founders will be indifferent to the structure of legislative procedures

bargaining in legislatures bargaining in legislatures is conducted according to formal rules specifying who may make proposals and how they will be decided legislative outcomes depend on those rules and on the structure of the legislature although the social choice literature provides theories about voting equilibria it does not endogenize the formation of the agenda on which the voting is based and rarely takes into account the institutional structure found in legislatures in our theory members of the legislature act noncooperatively in choosing strategies to serve their own districts explicitly taking into account the strategies members adopt in response to the sequential nature of proposal making and voting the model permits the characterization of a legislative equilibrium reflecting the structure of the legislature and also allows consideration of the choice of elements of that structure in a context in which the standard institution free model of social choice theory yields no equilibrium

renewable energy policy evaluation using real option model the case of taiwan abstract this study presents a policy benefit evaluation model that integrates cost efficiency curve information on renewable power generation technologies into real options analysis roa methods the proposed model evaluates quantitatively the policy value provided by developing renewable energy re in the face of uncertain fossil fuel prices and re policy related factors the economic intuition underlying the policy making process is elucidated while empirical analysis illustrates the option value embedded in the current development policy in taiwan for wind power in addition to revealing the benefits that re development provides when considering real options analytical results indicate that roa is a highly effective means of quantifying how policy planning uncertainty including managerial flexibility influences re development in addition to assessing the policy value of current re development policy this study also compares policy values in terms of internalized external costs and varying feed in tariff fit simulation results demonstrate that the re development policy with internalized co2 emission costs is appropriate policy planning from sustainability point of view furthermore relationship between varying fit and policy values can be shown quantitatively and appropriate fit level could be determined accordingly

substituting the end for the whole why voters respond primarily to the election year economy according to numerous studies the election year economy influences presidential election results far more than cumulative growth throughout the term here we describe a series of surveys and experiments that point to an intriguing explanation for this pattern that runs contrary to standard political science explanations but one that accords with a large psychological literature voters we find actually intend to judge presidents on cumulative growth however since that characteristic is not readily available to them voters inadvertently substitute election year performance because it is more easily accessible this end heuristic explanation for voters election year emphasis reflects a general tendency for people to simplify retrospective assessments by substituting conditions at the end for the whole the end heuristic explanation also suggests a remedy a way to align voters actions with their intentions providing people with the attribute they are seeking cumulative growth eliminates the election year emphasis

immigration and trade creation econometric evidence from canada immigrants may expand trade with their country of origin owing to superior knowledge of or preferential access to market opportunities the authors test this proposition using canadian trade data with 136 partners from 1980 to 1992 in an augmented gravity equation they find that a 10 percent increase in immigrants is associated with a 1 percent increase in canadian exports to the immigrant s home country and a 3 percent increase in imports they also find that among the primary categories of immigrants independents have the greater influence on trade immigration via the entrepreneur class appears to have less impact on trade than all other classes except refugees

investment in wind power and pumped storage in a real options model abstract promoting renewable energy has been a key ingredient in energy policy seeking to de carbonize the energy mix and will continue to do so in the future given the european union s high ambitions to further curb carbon emissions a wide range of instruments has been suggested and implemented in various countries of the eu a prominent policy promoting investment in renewable technologies is the use of feed in tariffs which has worked well at large scale in e g germany but which has only been implemented in a very limited way in countries such as the uk being subject to environmental uncertainties however renewables cannot be seen in isolation while renewables based technologies such as wind and solar energy for example suffer from uncertain loads depending on environmental conditions hydropower allows for the storage of water for release at peak prices which can be treated as a premium partially offsetting higher upfront investment costs in addition electricity prices will respond to changes in electric capacity in the market which is often neglected in standard investment models of the electricity sector this paper contributes to the existing literature in two ways it provides a review of a renewables based technology in a specific policy context and provides additional insight by employing a real options approach to investigate the specific characteristics of renewables and their associated uncertainties in a stylized setting taking explicitly into account market effects of investment decisions the prices of the model are determined endogenously by the supply of electricity in the market and by exogenous electricity price uncertainty the inclusion of market effects allows us to capture the full impact of public incentives for companies to invest into wind power and hydro pumped storage installations

a real option model for renewable energy policy evaluation with application to solar pv power generation in china abstract this study proposes a policy evaluation model from the perspective of government and investors the proposed model which integrates american option method and two factor learning curve method can be used to evaluate the unit decision value and save path rate for renewable energy development and examine the existence of balance point of interest several uncertain factors including non renewable energy cost carbon price renewable energy cost and price subsidy are all considered in this model the model has been applied to evaluate the solar photovoltaic pv power generation in china our empirical results show that real option analysis roa is more effective than net present value analysis npv when handling uncertainty under current level of subsidy the government would suffer loss and the investors could benefit so that it is difficult to achieve the balance of interest during the planning period with the reduction of subsidy rate they can achieve the balance of interest

the impact of chinese carbon emission trading scheme ets on low carbon energy lce investment china is planning to introduce emission trading scheme ets to decrease co2 emission as low carbon energy lce will play a pivotal role in reducing co2 emissions our paper is to assess the extent and the conditions under which a carbon ets can deliver lce investment in china we chose wind technology as a case study and a real option based model was built to explore the impact of a number of variables and design features on investment decisions e g carbon and electricity price carbon market risk carbon price floor and ceiling and on grid ratio we compute critical values of these variables and features and explore trade offs among them according to our work a carbon ets has a significant effect on wind power plant investment although it cannot support investment in wind power on its own carbon price stabilization mechanisms such as carbon price floor can significantly improve the effect of carbon ets but the critical floor to support investment is still much higher than the carbon price in china pilot etss our results show that other policy measures will be needed to promote low carbon energy development in china

political accountability and sequential policymaking abstract we develop a model of political accountability with sequential policymaking when a bureaucrat s actions are transparent his overseer faces a political time inconsistency problem she is tempted to revise her retention rule in the middle of the policymaking process as a result the bureaucrat s equilibrium behavior overemphasizes later tasks if the overseer knows the technology by which policies translate into outcomes then she can eliminate these distortions using task specific budget caps however if the overseer is uncertain about this technology such budget caps introduce ex post inefficiency when uncertainty is sufficiently large and consequential the overseer prefers an institutional environment with a fungible budget and no transparency such an environment allows the overseer to exploit the bureaucrat s expertise though at the cost of weaker overall incentives

the impact of international forces on the chinese wind power industry abstract the chinese wind power industry has achieved remarkable growth in the last two decades the total installed capacity of wind power in china has now surpassed that of the united states thereby making it the country with the largest installed wind power capacity in the world the independent and innovative capability of chinese wind turbine manufacturers has undergone continuous improvement and has now reached the point where the country has the capability to produce large scale wind turbines although the chinese domestic policy incentive has played a significant role in the rapid development of the chinese wind power industry the contribution made by external international forces should not be overlooked this research aims to establish a comprehensive model reflecting the international forces that impact on the chinese wind power industry this model consists of three subsystems i e 1 the international cooperation subsystem 2 the clean development mechanism cdm subsystem and 3 the import export subsystem using the model as part of the research the findings suggest that for the international cooperation subsystem joint research and development rd however its effect in terms of the diffusion of technical information and technical capability is weak similarly the degree of dependence of chinese wind turbine manufacturing on imports is weakening as domestic wind turbine manufacturers actively explore overseas markets this comprehensive model helps both international and domestic wind power investors to understand the impact of international forces on the chinese wind power industry resulting in better investment decisions and the consequential minimization of risk

inefficiency in legislative policymaking a dynamic analysis this paper develops an infinite horizon model of public spending and taxation in which policy decisions are determined by legislative bargaining the policy space incorporates both productive and distributive public spending and distortionary taxation the productive spending is investing in a public good that benefits all citizens e g national defense and the distributive spending is district specific transfers e g pork barrel spending investment in the public good creates a dynamic linkage across policymaking periods the analysis explores the dynamics of legislative policy choices focusing on the efficiency of the steady state level of

a foundation for markov equilibria in sequential games with finite social memory we study stochastic games with an infinite horizon and sequential moves played by an arbitrary number of players we assume that social memory is finite every player except possibly one is finitely lived and cannot observe events that are sufficiently far back in the past this class of games includes games between a long run player and a sequence of short run players and games with overlapping generations of players an equilibrium is purifiable if some close by behaviour is consistent with equilibrium when agents payoffs in each period are perturbed additively and independently we show that only markov equilibria are purifiable when social memory is finite thus if a game has at most one long run player all purifiable equilibria are markov

short term variations and long term dynamics in commodity prices in this article we develop a two factor model of commodity prices that allows meanreversion in short term prices and uncertainty in the equilibrium level to which prices revert although these two factors are not directly observable they may be estimated from spot and futures prices intuitively movements in prices for long maturity futures contracts provide information about the equilibrium price level and differences between the prices for the short and long term contracts provide information about short term variations in prices we show that although this model does not explicitly consider changes in convenience yields over time this short term long term model is equivalent to the stochastic convenience yield model developed in gibson and schwartz 1990 we estimate the parameters of the model using prices for oil futures contracts and apply the model to some hypothetical oil linked assets to demonstrate its use and some of its advantages over the gibson schwartz model

barriers and opportunities of using the clean development mechanism to advance renewable energy development in china studying the barriers and opportunities of using clean development mechanism cdm to advance renewable energy deployment in china has a practical significance to achieve its ambitious renewable energy plan which affects the global efforts to curb carbon emission this paper analyses the role of cdm in promoting renewable energy development in china by reviewing the cdm activities especially renewable energy cdm activities in china there are three barriers to utilizing cdm for renewable energy deployment namely the dilemma of additionality lower proportional certified emission reduction credit revenues on the investment and the lack of incentive for technology transfer whereas the opportunities of using cdm in promoting renewable energy development include the international carbon market redirection to renewable energy chinese renewable energy boom driven by a series of effective energy policies and additional finance from cdm supporting chinese renewable energy development based on the study on the barriers and opportunities the article considers that cdm is an indispensable incentive and a viable choice to promote renewable energy deployment in china crown copyright c 2010 published by elsevier ltd all rights reserved

wind farm investment risks under uncertain cdm benefit in china abstract china has set an ambitious target to increase its wind power capacity by 35 gw from 2007 to 2020 the country s hunger for clean power provides great opportunities for wind energy investors however risks from china s uncertain electricity market regulation and an uncertain energy policy framework mainly due to uncertain clean development mechanism cdm benefits prevent foreign investors from investing in china s wind energy the objectives of this paper are to 1 quantify wind energy investment risk premiums in an uncertain international energy policy context and 2 evaluate the impact of uncertain cdm benefits on the net present values of wind power projects with four scenarios this study simulates possible prices of certified emissions reductions cers from wind power projects project net present values npvs have been calculated the project risk premiums are drawn from different and uncertain cer prices our key findings show that uncertain cdm benefits will significantly affect the project npvs this paper concludes that the chinese government needs revising its tariff incentives most likely by introducing fixed feed in tariffs fits and re examining its cdm granting policy and its wind project tax rates to facilitate wind power development and enable china to achieve its wind energy target

incumbent performance and electoral control in the pure theory of electoral competition citizens compare the platforms of the candidates and vote for the one whose platform is preferred candidate strategies are identified with promises about future performance in office models of this sort have been developed in both static mckelvey 1975 and dynamic kramer 1977 i settings and all appear to have the property that if the set of alternatives is large enough in some sense equilibrium platforms rarely exist but these models have another feature that is quite as disturbing as their instability in the static setting discussed by mckelvey little attention is paid to the possibility that once in office the politician s preferences may diverge from those of his constituents and that he may therefore choose policies at variance from his platform instead it is simply assumed that promises will be kept whether or not such behavior is congruent with the interest of the officeholder it is sometimes argued that an enforcement mechanism may exist to discipline politicians for failing to keep promises but without a specification of the mechanism it is not obvious that it would be in the interests of the

examining the economic and environmental effects of emissions policies in china a bayesian dsge model abstract the purpose of this study is to build an energy emissions economy dynamic stochastic general equilibrium model to examine the economic and environmental effects of the carbon tax and carbon intensity target the model is calibrated to china s economy the results show that both the carbon tax and carbon intensity target policies have a negative effect on china s economy and environment however the carbon tax exerts more negative effects on the economy and environment than the carbon intensity target moreover the carbon tax shock lasts shorter than the carbon intensity target shock the findings additionally indicate that the effects of the increase in the productivity of energy sectors are greater than those of the increase in the productivity of other sectors thanks to the low carbon technology shock china s carbon dioxide emissions will reduce and output will increase taken together this study highlights the key policy implications associated with the results

subsidies in carbon finance for promoting renewable energy development abstract faced with decreasing exhaustible nonrenewable resources and climate change resulting from the use of fossil energy it is urgent to accelerate the development of renewable energy but the development of renewable energy requires abundant financial support both from banks and governments this article considers bank loans to develop renewable energy and highlights the effects of government subsidies by using a microeconomic model and taking all stakeholders including the government banks and shareholders of the firm into consideration this study finds that government subsidies raise outputs and debt levels of renewable energy firms and improve shareholder value as well more importantly financial debts stimulate firms outputs but decrease the net profit per unit of debt due to the limited liability effects finally subsidy policy plays a critical role in renewable energy development because environmental efficiencies of subsidies decrease with the subsidy degree other valuable conclusions would be achieved if principal agent problem and other corporate governance factors are employed

the evolving role of carbon finance in promoting renewable energy development in china abstract the world is negotiating what the international climate change regime will look like after 2012 the year that current kyoto protocol greenhouse gas emissions reduction targets expire and the future of the clean development mechanism cdm is under discussion critics claim the scale of reductions that the cdm is driving in the developing world is insufficient from a scientific perspective if we are to avoid dangerous climate change that the project by project crediting process is inefficient and that the reductions being achieved are not additional meaning they would have happened anyway and thus should not be financially supported yet the efficacy of cdm must be examined in the broader context of carbon mitigation in the developing world and the actions that are taking place this paper examines the role that the cdm has played in promoting renewable energy development in china in order to assess how international carbon finance can best be used to help promote emissions mitigation in the developing world it also assesses how several options under consideration for reforming the current structure of the cdm in particular and developing country engagement in general may impact renewable energy development in china in the coming years

soft and hard price collars in a cap and trade system a comparative analysis we use a stochastic dynamic framework to compare price collars price ceilings and floors in a cap and trade system with uncertainty in the level of baseline emissions and costs we consider soft collars which provide limited volume of additional emission allowances a reserve at the price ceiling and hard collars which provide an unlimited supply of additional allowances thereby preventing allowance prices from exceeding the price ceiling conversely allowances are removed from the market if prices fall to the floor we find that increasing the size of the reserve strictly lowers expected net present values of compliance costs however there is a diminishing effect as the allowance reserve is expanded most of the expected cost savings are achieved with a modest reserve consequently a rather limited soft price collar could provide considerable assurance about cost while preventing the possibility that emissions could spiral out of control

the dynamics of political compromise we characterize efficient self enforcing divisions of political or economic surplus between two parties that interact repeatedly the party in power can decide the allocation and the parties political strength changes according to a markov process we find that the share of the party currently in power depends not only on its current strength but also on whether it had previously been even stronger since it last came to power we find that the constitutional supermajority requirements that attempt to constrain the use of power can counterproductively create less compromise

optimal retention in agency problems this paper studies the interaction between a single long lived principal and a series of short lived agents in the presence of both moral hazard and adverse selection we assume that the principal can influence the agents behavior only through her choice of a retention rule this rule is further required to be sequentially rational i e no precommitment is allowed we provide general conditions under which equilibria exist where a the principal adopts a cut off rule under which agents are retained only when the reward they generate exceeds a critical bound and b agents separate according to type with better agents taking superior actions we show that in equilibrium a retained agent s productivity is necessarily declining over time but that retained agents are also more productive on average than untried agents due to selection effects finally we show that for each given type agents of that type are more productive in the presence of adverse selection than when there is pure moral hazard i e when that type is the sole type of agent in the model nonetheless adding uncertainty about agent types cannot benefit the principal except in uninteresting cases

real options theory applied to electricity generation projects a review abstract real options ro theory is well known for enhancing the value of projects under uncertainty this is achieved by modelling the flexibility that managers possess to adjust the projects in response to changes in their environments based on this ro theory could be used to tackle current energy and environmental issues by enhancing the value of electricity generation projects egp especially renewable energy projects rep the potential of ro theory to increase the value of egp and rep has been a driver for new research in the topic however existing literature is still scarce diverse and tends to neglect the state of the art of ro theory e g ro in the design of projects ro studies tend to ignore the use of ro in the design of projects as they are difficult to formulate without the help of experts on the projects designs this paper aims to encourage novel research in the application of ro theory to egp and rep for this purpose a critical review of ro theory its state of the art and its applications to egp and rep is presented this review identifies current areas of interest and gaps in knowledge in this research area it is concluded that new and novel ro research should address the state of the art of ro theory and uncertainties that are exclusive for specific types of projects this future research will require the involvement of electrical engineers specialised in the design of egp and rep

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

can the future eu ets support wind energy investments abstract this article discusses how the future emissions trading scheme legislation should be designed to allow the european union to comply with the 20 co 2 emissions reduction target while at the same time promoting wind energy investments we examine whether co 2 prices could eventually replace the existing support schemes for wind and if they adequately capture its benefits the analysis also looks at the effectiveness of the clean development and joint implementation mechanisms to trigger wind projects and technology transfer in developing countries we find out that climate policy is unlikely to provide sufficient incentives to promote wind power and that other policies should be used to internalise the societal benefits that accrue from deploying this technology co 2 prices can only reflect the beneficial impact of wind on climate change but not its contribution to the security of supply or employment creation a minimum price of around 40 tco 2 should be attained to maintain present support levels for wind and this excludes income risks and intermediation costs finally cdm improves the return rate of wind energy projects in third countries but it is the local institutional framework and the long term stability of the co 2 markets that matters the most

can carbon pricing support onshore wind power development in china an assessment based on a large sample project dataset abstract there is much discussion about whether the rapid expansion of onshore wind power in china is sustainable given the decrease in feed in tariffs fit it is unclear whether the recently launched nationwide carbon pricing system which will include 1700 power companies can compensate for decreasing fits and possibly provide new incentives for wind power developments this paper investigates the ability of carbon pricing policies to compensate for declining fits in support of onshore wind power investment in china first we constructed a dataset of 2059 onshore wind power projects from china s thirty provinces between 2006 and 2015 to estimate the levelized costs of electricity lcoe this dataset was used to assess the profitability of each wind project for different carbon prices varying levels of fits curtailment rate and discount rate our findings suggest that the carbon price can compensate partially for the revenue loss caused by declining fits as well as improving the profitability of projects however current carbon prices in china s carbon emission trading pilots are not sufficiently high to compensate for the revenue losses especially under the grid parity scenario consequently without fits the sustainable development of onshore wind power in china is uncertain a sensitivity analysis of the effect of the carbon pricing policy demonstrates that in the case of higher investment risk and more serious curtailment the effect of carbon pricing policy on promoting the wind power investment seems to be more significant

demand competition and policy compromise in legislative bargaining i propose a new majoritarian bargaining model in which more than one implicit proposal can be on the table at the same time institutional differences from system to system affect the order of play the equilibrium majorities and the policy outcome the ex post distribution of payoffs within a winning coalition is however invariant to fundamental institutional differences and it is always proportional to the distribution of relative ex ante bargaining power the bargaining process is modeled as a sequential demand game in which players are called to propose a policy and to specify their desired share of the private benefits related to being in office the order of play is endogenous and the distribution of payoffs within an equilibrium majority usually does not depend on who is the proposal maker the role of the head of state and the advantages to center parties are also studied

the limited effect of eu emissions trading on corporate climate strategies comparison of a swedish and a norwegian pulp and paper company this article article examines to what extent and how the eu ets has influenced the climate strategies of two nordic pulp and paper companies swedish sca and norwegian norske skog rising electricity prices are perceived to be the greatest effect of the scheme the eu ets has served to reinforce commitments to improve energy efficiency and reduce co2 emissions in both companies studied procedures like monitoring of co2 emissions and accounting for co2 prices have become more significant since the introduction of the eu ets but the scheme has not triggered a search for innovative low carbon solutions due to differences in market factors and production factors sca has been more active than norske skog in investing in and implementing co2 lean actions future studies of climate mitigation activities strategies and innovations in the pulp and paper industry should involve more in depth investigation of the interactions between such factors and the eu ets c 2013 elsevier ltd all rights reserved less

how do senators vote disentangling the role of voter preferences party affiliation and senate ideology this paper develops a methodology for consistently estimating the relative weights in senator utility functions despite the fact that senator ideologies are unobserved the empirical results suggest that voter preferences are assigned only one quarter of the weight in senator utility functions the national party line also has some influence but the senator s own ideology is the primary determinant of roll call voting patterns these results cast doubt on the empirical relevance of the median voter theorem estimation of the model requires only roll call voting data making it widely applicable copyright 1996 by american economic association

what have you done for me lately release of information and strategic manipulation of memories how should a rational agent politician employee advertiser release information in order to manipulate the memory imperfections of his forgetful assessor electorate supervisor consumer this article attempts to answer this question using a memory model based on the principles of recency similarity and repetition i show that the problem of a rational agent who releases information to a forgetful assessor can be modelled as a standard dynamic optimisation problem and we describe the properties of the optimal profile for releasing information the theoretical results are applicable in a wide range of social and economic contexts such as political campaigns employee performance evaluations and advertising strategies

the dynamic linkage effect between energy and emissions allowances price for regional emissions trading scheme pilots in china abstract china s emissions trading scheme cets pilots are emerging and fragmented markets these emissions allowances markets may exhibit a different fundamental price process from the european union s eu and the united states us emissions trading scheme ets the dynamic linkage effects between energy and emissions allowances prices are investigated for regional ets pilots in china using cointegration techniques the empirical results confirm that in the long run coal oil and natural gas prices are the main determinant factors of regional emissions allowances prices except for the second phase beijing ets pilots however their long run cointegration relationships in the beijing and shanghai pilots are not exactly in line with the guangdong and hubei pilots in the short run the changes in oil and natural gas prices in the second phase beijing ets pilot the natural gas prices in the shanghai ets pilot and the coal prices in the hubei ets pilot are found to have significant effects on regional emissions allowances prices in china finally regional energy pricing inefficiency regional emissions trading market overreaction and their inefficient fundaments may provide major obstacles in reducing the effectiveness of the fossil energy price pass through to emissions allowances prices in regional ets pilots

the wrong kind of transparency in a model of career concerns for experts when is a principal hurt from observing more information about her agent this paper introduces a distinction between information on the consequence of the agent s action and information directly on the agent s action when the latter kind of information is available the agent faces an incentive to disregard useful private signals and act according to how an able agent is expected to act a priori this conformist behavior hurts the principal in two ways the decision made by the agent is less likely to be the right one discipline and ex post it is more difficult to evaluate the agent s ability sorting the paper identifies a necessary and sufficient condition on the agent signal structure under which the principal bene ts from committing not to observe the agent s action the paper also shows the existence of strategic complementarities between information on action and information on consequence the results on the distinction between action and consequence are then used to interpret existing disclosure policies in delegated portfolio management in particular they are consistent with hitherto puzzling evidence that mutual funds systematically overperform pension funds

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

seniority in legislatures we construct a stochastic game model of a legislature with an endogenously determined seniority system we model the behavior of the legislators as well as their constituents in an infinitely repeated divide the dollar game each legislative session must make a decision on redistributional issues modeled as a divide the dollar game however each session begins with a vote in which the legislators decide by majority rule whether or not to impose on themselves a seniority system legislative decisions on the redistributional issues are made by the baron ferejohn rule an agenda setter is selected by a random recognition rule which in our model is a function of the seniority system selected the agenda setter makes a proposal on redistributional issues and the legislature then votes whether to accept or reject the agenda setters proposal if the legislature rejects the proposal another agenda setter is randomly selected and the process is repeated if the legislature accepts the proposal the legislative session ends and the voters in each legislative district vote whether to retain their legislator or throw it out of office the voters verdict determines the seniority structure of the next period legislature we find a stationary equilibrium to the game having the property that the legislature imposes on itself a non trivial seniority system and that legislators are always reelected
