the renewables portfolio standard in texas an early assessment texas has rapidly emerged as one of the leading wind power markets in the united states this development can be largely traced to a well designed and carefully implemented renewables portfolio standard rps the rps is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation though replacing existing renewable energy policies with an as of yet untested approach in the rps is risky early experience from texas suggests that an rps can effectively spur renewables development and encourage competition among renewable energy producers initial rps targets in texas were well exceeded by the end of 2001 with 915 mw of wind installed in that year alone rps compliance costs appear negligible with new wind projects reportedly contracted for well under 3 us cent k wh in part as a result of a 1 7 us cent kwh production tax credit an outstanding wind resource and an rps that is sizable enough to drive project economies of scale obliged retail suppliers have been willing to enter into long term contracts with renewable generators reducing important risks for both the developer and the retail supplier finally the country s first comprehensive renewable energy certificate program has been put into place to monitor and track rps compliance c 2002 published by elsevier science ltd less

impacts of wind and solar spatial diversification on its market value a case study of the chilean electricity market abstract renewable energy is expected to become the main electricity source in the world in the coming decades with solar and wind power taking a big share of the energy supply although there has been a remarkable advance on renewable energy technologies their integration is still difficult for regulators market designers and system operators due to the high variability and limited predictability of solar and wind resources measures can be adopted to ease their integration among them geographical diversification there is plenty of literature about the diversification of solar and wind resources and there is a common conclusion greater dispersion smooths out power production however literature on the effects of spatial diversification on the power system electricity prices and renewable energy market value is much scarcer this paper studies the effects of spatial diversification and questions whether integration policies are incentivizing the placement of renewable generators where they provide the highest value to the electricity system in chile using real data and a simplified dispatch model the analysis presented shows evidence of the effects of diversification on wind and solar market value in chile results suggest that spatial diversification has a strong positive effect on the market value of renewable energy especially in scenarios with active transmission and hydro storage constraints wind market value may vary up to us 10 mw h depending on the level of diversification and the spatial and temporal constraints of the system and given current storage capacity of hydro reservoirs the solar market value may increase us 5 mw h due to diversification if transmission capacity is enough even though these results must be observed with caution because they depend on the assumptions made there is an important effect of renewable spatial diversification that should be observed by regulators

pocketbook voting social preferences and expressive motives in referenda we develop and test a theory of voting and turnout decisions that integrates self interest social preferences and expressive motives our model implies that if pocketbook benefits are relevant voters either perceive their impact on the outcome to be non negligible or expressive motivations do not play a role in the decision on how to vote conversely if own pocketbook benefits do not explain voting then voting is expressive if the perceived probability of being pivotal is non negligible social preferences and expressive concerns are observationally equivalent our empirical analysis studies collective choices which are analogous to decisions on local public goods we consider referenda among university students on whether to collectively purchase deeply discounted flat rate tickets for public transportation and cultural amenities individual usage data allow quantifying the monetary benefits associated with each ticket as voters had precise information on the individual costs and benefits our setting comprises a real world laboratory of direct democracy we find that monetary benefits strongly influence participation and voting however social or expressive motives such as stated altruism environmental concerns and paternalism are decisive for a significant minority our results rule out purely expressive voting and imply that a substantial share of the electorate perceived their impact on the outcome to be non negligible

an experimental study of truth telling in a sender receiver game a recent experimental study of cai and wang 2005 on strategic information transmission reveals that subjects tend to transmit more information than predicted by the standard equilibrium analysis to evidence that this overcommunication phenomenon can be explained in terms of a tension between normative social behavior and incentives for lying we show in a simple sender receiver game that subjects incurring in costs to punish liars tell the truth more often than predicted by the logit agent quantal response equilibria whereas subjects that do not punish liars after receiving a deceptive message play on the aggregate equilibrium strategies thus we can partition the subject pool into two groups one group of subjects with preferences for truth telling and one taking into account only material incentives

redistribution income and voting a model that reconciles the positive association between income and voting found in cross sectional studies with the negative correlation between income and turnout over time is developed voting is modeled as a group rational activity voter turnout rates in the united states for the 1948 1960 1968 and 1980 elections are used to test the model voter turnout is found first to fall and then to rise as families move up the income distribution voter turnout also rises as real wages fall as educational attainment increases as elections become closer and as poll taxes and literacy tests are removed

expressive voting and electoral equilibrium there are two rival accounts of rational voting in the public choice tradition the mainstream instrumental account that sees the vote as a revelation of preference over possible electoral outcomes essentially analogous to a market choice and the expressive account that sees the vote as expressing support for one or other electoral options rather like cheering at a football match this paper attempts to lay out some of the implications of the expressive account of voting for the issue of who votes as well as for the nature of political equilibrium and to compare these implications with those derived from the instrumental account we also identify and discuss the alternative views of the domain of electoral politics associated with the instrumental and expressive accounts of voting and sketch a route towards the integration of expressive and instrumental ideas in the analysis of rational electoral politics

partisan bias and expressive voting abstract we conduct an experiment to characterize the expressive voting behavior of political partisans we find that participants who are asked to vote on the answer to factual questions tend to offer more partisan responses than those who must answer as decisive individuals we further test whether voters exploit corrective information that sometimes challenges their partisan views when information is available we observe smaller partisan gaps and more correct responses especially when the information is free when information is costly to acquire we find that voters generally choose to remain uninformed consistent with the downsian theory of rational ignorance

renewables portfolio standard a means for trade with electricity from renewable energy sources abstract this paper discusses the main support mechanisms for enhancing the deployment of renewable energies re implemented in different industrialised countries the focus is on the electricity sector where deregulation and liberalisation has led to market opening and introduction of competition in the formerly strongly regulated power market under open market conditions price regulation mechanisms in favour of renewable energies which were used by many governments to support renewables tend to be considered as being inappropriate because they lead to distortions in competition and are difficult to abolish once market participants got used to them therefore the idea of creating a demand for re instead of supporting supply is gradually spreading this paper concentrates on the renewables portfolio standard rps which is a considerably new instrument that is aimed on the demand side and has only recently entered discussion it is based on legislatively mandating a percentage share of electricity generated from renewables and proved with certificates before this new means is discussed in more detail a short overview of the existing supply side mechanism is given to point out the different approach in addition examples of some countries already having some experience with the rps are given to show the present status of implementation derived from these theoretical considerations and practical experiences the paper discusses possible impacts on market participants they depend strongly on the outline of the rps and the organisation of the electricity sector adopted as a conclusion the introduction of an rps cannot alone solve the problem of enhancing the use of re however the advantages are a higher degree of competition among generators or developers of re technology more freedom of choice concerning the options for meeting the requirement and perhaps less government expenditures also experiences with national certificate trading within the rps system could ease the way for international or at least european trading systems like the emissions trading as proposed in the kyoto protocol

health behavior health knowledge and schooling the positive correlation between schooling and good health is well documented one explanation is that schooling helps people choose healthier life styles by improving their knowledge of the relationship between health behaviors and health outcomes that is schooling improves the household s allocative efficiency in producing health this empirical study uses direct measures of health knowledge to test this explanation part of the relationship between schooling and the consumption of cigarettes alcohol and exercise is explained by differences in health knowledge however most of schooling s effects on health behavior remain after differences in knowledge are controlled for

impact of deployment of renewable portfolio standard on the electricity price in the state of illinois and implications on policies abstract the renewable portfolio standard rps of the state of illinois specifies a schedule for the fraction of electricity produced from wind to be phased in through 2025 the price of electricity due to implementation of rps in order to achieve a six year payback on investment on new wind farms was estimated for six scenarios that examined the effect of electricity consumption growth rate production tax credit of 0 022 kw h or unrestricted investment tax credit of 30 and projected changes in installed project costs in all cases the electricity price was found to be dominated by the installed project cost capital cost thus any policy that affects the capital cost directly or indirectly would have a significant effect on the electricity price whereas investment tax credit has a direct effect policies that encourage technology improvement and improve transmission lines would have a similar effect of lowering the capital cost carbon tax on the other hand would increase the electricity price to the consumers although it offers other benefits

the effect of the expansion of the voting franchise on the size of government this paper examines the claim that expansion of the voting franchise has been an important factor in the growth of government state government spending and state and local spending are explained using a panel of 46 states for 1950 88 elimination of poll taxes and literacy tests led to higher turnout particularly among the poor and a poorer pivotal voter as predicted we find that these changes a fall in the income of voters relative to state income and the ouster of republicans from state government led to a sharp rise in welfare spending but no change in other spending

consumer demand for nutrition versus taste in four major food categories this study addresses the trade off between nutrition and taste in expenditure on breakfast cereal milk bread and soft drinks within each category products have similar cost and convenience but have markedly different flavor and nutritional content using annual expenditure data for a large sample of households participating in the acnielsen homescan system we regress a measure of healthiness on household demographics and market prices and find that households with college educated heads and higher incomes made significantly healthier choices in all four categories these effects are puzzling in that the nutritional differences between products were well known to consumers and there are no cost or convenience differences between them the presence of children was associated with less healthy choices especially for cereal and bread while older households made healthier choices in all categories except milk

the downsian voter meets the ecological fallacy this paper presents evidence that voter participation does not depend on the probability that one vote is decisive an extensive summary of the empirical participation literature is provided which shows that most but not all studies have found that turnout in an electoral district is higher when the race is closer individual level vote regressions for the 1979 and 1980 canadian national elections are estimated using objective measures of closeness as opposed to self reported measures the main finding is that a citizen is no more likely to vote in a close election than in a lands lide election district level turnout regressions for the same elections are also estimated and a significant relation between closeness and turnout is observed this suggests that aggregation bias may generate a spurious closeness turnout relation in district level regressions

do closeness and stake increase voter turnout evidence from election results in small french towns in brittany abstractdo closeness and stake increase voter turnout evidence from election results in small french towns in brittany regional studies this article explores the determinants of second round voter turnout in small french towns with a focus on two hypotheses first an increase in the closeness of the race may lead to an increase in turnout second a higher seats stake that is a higher proportion of the total number of seats that remain to be filled in the second round of the election may increase turnout results show that increases in both closeness and seats stake lead to higher voter turnout thus evidence is given in favour of the assumption of rationality in voting in local elections

what is the probability your vote will make a difference i introduction what is the probability that one vote will make a difference this is of interest in the utility theory of voting and also for campaign strategists who must assess the costs and benefits of attempting to persuade or turn out voters in particular states 1 in a presidential election the probability that your vote is decisive is equal to the probability that your state is necessary for an electoral college win times the probability the vote in your state is tied conditional on your state being necessary broadly speaking there are three ways of estimating the probability of a decisive vote the first approach and the oldest in the literature 2 is to set up a theoretical model for the joint distribution of the popular vote margin in the separate jurisdictions in this case the 50 states plus the district of columbia and then analytically compute the probability of each state being nationally decisive and locally tied such models offer important insights but are not directly useful for presidential elections given that our interest is in the particularities of individual states in 2008 rather than on general properties of an electoral system the second approach is purely empirical an estimate of the form y n where n is the number of elections in some large historical sample and y is the number that were tied elections are very rarely tied so one can instead use an estimate such as y 2 000 n where y is now the number of elections decided by less than 1 000 votes such an empirical analysis can be embedded into a regression of vote differential on election level predictors mulligan and hunter 2003 use such a model for estimating the average probability of a decisive vote in legislative elections and gelman katz and bafumi 2004 use the distribution of aggregate vote margins to study the dependence of the probability of a tie on the number of voters 3 unfortunately the complex structure and the small number of presidential elections rule out a purely empirical approach in this case the third method which we use here is to set up a forecasting model for the current election the uncertainties for the 50 statewide elections in such a model should be correlated or equivalently the model should have a national error term and possibly regional error terms in addition to any independent state errors given a forecast that is a joint probability distribution one can calculate the probability of decisive vote using simulation or in a setting such as a national election in which the probability of a tied election is tiny one can use a mix of simulation and analytic calculations as was done by gelman king and boscardin 1998 4 ii method we use a state by state election forecast computed on october 24 2008 based on the latest opinion polls silver 2008 earlier in the campaign polls are not particularly informative and it is better to use regression based forecasts at least to account for possible national swings see lock and gelman 2008 and for further discussion wlezien and erikson 2004 and the references therein by late october however polls are close to the actual election outcome and so it is reasonable to construct a forecast distribution using poll aggregation 5 the result of our forecasts is a 10 000 x 51 matrix representing 10 000 computer simulations of the election with each simulation including the vote margin for obama e g a margin of 0 208 in alabama corresponds to obama and mccain receiving 60 4 and 39 6 respectively of the two party vote in the state we convert this percentage to a numerical vote margin by multiplying by the voter turnout in the state which we estimate by taking the two party turnout from 2004 and adding 4 corresponding to population increase and another 4 to account for an anticipated increase in turnout this year 6 as discussed earlier the simulations for the states are correlated the joint probability distribution of the 51 election outcomes includes uncertainty about the national swing as well as state by state fluctuations

entrepreneurship social mobility and income redistribution in south india development economists have been preoccupied with the problem of increasing the size of the gnp pie to the relative neglect of its distribution despite the recent disenchantment with the viewpoint that all classes share in the benefits of industrial growth empirical data on the distribution of income business opportunity and economic power are in short supply many of the studies on entrepreneurship and economic development when they are not apologetics for ruthless capitalist exploitation as paul baran suggests extol the achievements of the capitalist entrepreneur without examining class origins and monopoly advantage joseph schumpeter sees entrepreneurs irrespective of class origin as heroic figures with the dream and will to found a private kingdom to conquer adversity to achieve success for its own sake and to experience the joy of creation for gustav papanek 1967 the private entrepreneur who is frugal diligent far sighted remarkably able and willing to take political risks is in large part responsible for the success of pakistan in achieving rapid industrialization

rational choice and turnout turning out to vote is the most common and important act of political participation in any democracy voting is also less well understood and explained empirically than other political acts engaged in regularly by citizens turnout however presents a special problem for rational choice theories of politics for it is taken to be the paradigmatic example of the problem of collective action in which although all may benefit from voting it is rarely in the individual s self interest to vote this paper begins by examining the problem of explaining turnout a basic form of rational choice models of turnout is developed basic in the sense that it is common to all such models this basic model is shown to be incomplete and the two most important models the calculus of voting and the minimax regret model are illustrated as alternative ways to complete this basic model along with mention of game theoretic models their strengths and weaknesses are then assessed the remainder of the paper argues that rational choice accounts of turnout are possible the first step is to argue that turnout is not an especially problematic version of the collective action problem because it is for many a low cost low expected benefit decision a strategic politicians account of turnout and campaigns is examined next a reinterpretation of the intrinsic benefits of voting is then considered and is used to examine the most important substantive problem in the turnout literature its decline these steps i argue make theories of ordinary political decisions at once both more political and more integrated into the politics of the larger system

closeness expenditures and turnout in the 1982 u s house elections students of elections have repeatedly found that the closeness of an election is modestly correlated with turnout this may be due to a direct response of instrumentally motivated voters but recent theoretical work casts doubt on the adequacy of this explanation another possibility is that elite actors respond to closeness with greater effort at mobilization we explore the latter possibility by using fec and state data on campaign expenditures in house senate and gubernatorial races our results indicate that closeness has an effect at both the mass and elite levels we also provide quantitative estimates of the effect of senate and gubernatorial expenditure on house turnout

to vote or not to vote the paradox of nonvoting one paradox of voting states that in a general election in which many citizens vote the probability that a single voter can affect the outcome is so small that in general citizens have no rational reason for voting however if all citizens accept this reasoning then none will vote and so each vote has a large probability of affecting the outcome hence all should vote after all the adoption of mixed strategies resolves this paradox if each citizen adopts a certain small probability of voting then the actual number of citizens voting will be just enough to make it worth those citizens while to vote a nash equilibrium point thus occurs here we compute nash equilibria for the simple case of majority voting for the more complicated case of composite voting for example as in a presidential election we draw certain qualitative inferences

pinocchio s pupil using eyetracking and pupil dilation to understand truth telling and deception in sender receiver games we conduct laboratory experiments on sender receiver games with an incentive for senders to exaggerate such as security analyst s painting a rosy picture about earnings prospects our results show that overcommunicati on messages are more informative of the true state than they should be in equilibri um is consistent with a level k model eyetracking shows that senders look much more on the payoff rows corresponding to the true state and much less at receiver payoffs than at their own payoffs senders pupils also dilate more when their deception is larger in magnitude together these data are consistent with the hypothesis that figuring out ho w to deceive another player is cognitively difficult as assumed in the level k mod el a combination of sender messages and lookup patterns predicts the true state about t wice as often as predicted by equilibrium using these measures would enable receiver subjects to hypothetically earn up to 16 21 percent more than they actually do

future wind and solar power market values in germany evidence of spatial and technological dependencies abstract achieving ambitious climate targets entails an extensive utilisation of renewable energy sources however due to weather dependent fluctuations generation from variable renewable energy vre sources is characterised by significantly lower market values in comparison to conventional technologies reinforced by a decline in electricity prices this development poses interesting questions as to its drivers and to what extent market values of wind and solar power can be influenced by the design of electricity markets against this background a scenario based analysis is conducted to trace the future development of market values using endogenously derived electricity prices considering different regional and technological vre diversification strategies and investments into vre technologies on a myopic basis the results show a continued decline in market values with increasing regional discrepancies indicating a growing importance of interregional interdependencies for assessing the profitability of vre furthermore from a system point of view a more distributed allocation of onshore wind capacities to contend with declining market values does not always prove to stabilise market values by facilitating a more constant feed in pattern contrary to expectation finally replacing onshore with offshore wind energy appears to be beneficial as it can lead to an overall increase in the market values of offshore onshore as well as pv generation technologies compared to other mitigation strategies this result raise interesting questions about the systemic economic value of offshore wind despite its higher lcoe in the context of market integration of vre

where do all the windmills go influence of the institutional setting on the spatial distribution of renewable energy installation abstract promoting renewable energy sources is one policy response to climate change not only is there currently a debate over the best policy instrument it is also discussed whether the renewable energy production should be expanded centralized at locations with the highest production potential or decentralized close to load it is yet not fully understood what influences the spatial distribution of renewable energy installation i assess the effect of subsidy scheme and market design on the spatial distribution of wind energy installations by comparing a feed in tariffs versus market premiums and b uniform versus nodal pricing the analysis is based on theoretical considerations and using a six node test model that reflects the consumption and renewable resource distribution in several countries and regions the institutional setting has great influence on the spatial distribution and resulting system costs with uniform pricing a market premium only leads to a more decentralized expansion of renewable energy production than a tariff when sites share similar wind conditions spatially more distributed expansion of wind power performs better in terms of total costs and share of wind power in final demand when networks are restricted

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

the renewable portfolio standard design considerations and an implementation survey renewables have social and environmental bene ts compared to conventional electricity sources but are rarely competitive on a strict nancial cost basis this is because conventional sources are sometimes subsidized their full pollution costs are ignored and renewables involve newer higher cost technologies whose relative costs will fall with commercialization governments use several mechanisms to support renewables including direct nancial support grants loans indirect support r d demonstrations reform of nancial costs of conventional sources subsidy removal pollution taxes and the renewable portfolio standard rps the rps requires a minimum share of electricity from renewable energy sources its use is spreading because it maintains an incentive for renewable producers to reduce costs links the regulated market outcome to an environmental target and reduces government involvement although it is too early to evaluate fully its e ectiveness the survey for this study explored implementation issues in three european countries nine us states and australia and found the following the rps target is usually set to have environmental bene ts without causing signi cant price increases cost caps are sometimes used most jurisdictions limit eligibility to gridconnected domestic renewables the rps is usually applied to producers rather than consumers and to energy output not capacity flexibility mechanisms are desired but a challenge to implement administration in the us and australia is by government with delegation to independent utility regulators while in europe it is more the responsibility of government everywhere the rps is applied alongside other mechanisms of renewables support 2001 elsevier science ltd all rights reserved

cheap talk with two audiences these problems have in common a simple structure an informed sender says something to two interested but uninformed receivers who then take actions based on their beliefs these actions affect the sender as well as the receivers in this paper we study how costless nonverifiable claims cheap talk can affect these beliefs and hence the actions and how the incentives for truthful revelation to one receiver are affected by the presence of the other we then ask how welfare is affected by whether claims are made in public or in private as some of the above examples suggest public messages may be more credible than private messages addressed to either audience one possibility is that the presence of one audience can discipline the sender s relationship with the other we call this one sided

experimental evidence on the evolution of the meaning of messages in sender receiver games an experiment this paper experimentally investigates the evolution of message meanings when talk is cheap we consider communication between a privately informed sender and a receiver when the sender s message does not affect payoffs directly sender receiver games introduced by jerry green and nancy stokey 1980 and vincent p crawford and joel sobel 1982 provide the simplest stylized environment in which communication is essential communication is the only way to link the receiver s action to the sender s private information in addition sender receiver games have been widely used to study communication in accounting economics finance and political science intuition strongly suggests that effective communication will evolve when the players interests are closely aligned however there is always a nash equilibrium in which the sender randomizes uniformly across all messages such babbling equilibria are proper roger b myerson 1978 blume 1994 and even strategic stability elon kohlberg and jeanfrancois mertens 1986 does not rule out uninformative equilibria in general in response a literature developed that formulates equilibrium selection criteria by appealing to the existence of a commonly understood language matthew rabin 1990 steven a matthews et al 1991 joseph farrell 1993 that can be used to formulate credible deviations from equilibrium unfortunately the selection criteria from this literature are frequently strong enough to remove all equilibria from consideration in addition these arguments are vulnerable to stiglitz s observation in koo cho and david m kreps 1987 that successful deviations from equilibrium may induce further deviations which in turn may undermine the credibility of the original deviations both problems can be avoided by a dynamic approach as in rabin and sobel 1996 we also adopt a dynamic perspective but do not require messages to have a priori meanings instead distinct meanings may emerge endogenously this is important for communication across cultures and for language change 2 we are guided by recent results of blume department of economics university of iowa iowa city ia 52242 dejong department of accounting university of iowa iowa city ia 52242 kim department of economics sung kyun kwan university seoul 110 745 korea sprinkle department of accounting university of wisconsin madison wi 53706 we thank joyce berg vince crawford robert forsythe joel horowitz deirdre mccloskey forrest nelson larry samuelson gene savin joel sobel and especially two anonymous referees for their advice and suggestions we benefitted from comments and discussions resulting from presentations at the 1994 summer meetings of the econometric society the 1996 social learning workshop at suny stony brook the io me gt workshop at the university of iowa the university of bonn the university of bielefeld the center for economic research at tilburg university ohio state university seoul national university and texas a m university we are grateful for financial support from the college of business administration at the university of iowa the ira b mcgladrey institute and the national science foundation

low income and poor health choices the example of smoking people with low incomes tend to make less healthy consumption choices than do high income people in the case of food agricultural economists have investigated whether this is due to the cost of a healthy diet studies of various aspects of the nutrition income nexus have generally been inconclusive we investigate a different possibility motivated by the fact that low income individuals are most likely to be smokers which cannot be due to limited budgets drawing on a body of related literature we develop a model in which income serves not only as a budget constraint but also as a source of future utility we test the model by estimating logistic models of beginning and quitting smoking we find support for the idea that low income consumers make less healthy choices because they face lower costs in terms of foregone future utility

rewards experience and decision costs in first price auctions consistent with a model of asymmetric risk aversion subjects in first price auctions consistently bid above the risk neutral nash prediction it has been argued that this is due to low opportunity cost of deviating from the risk neutral bid we increase opportunity cost and payoff levels by factors of 0 1 5 10 and 20 from the normal levels generating payoffs up to 250 for risk neutral subjects and observe an insignificant increase in the slope of individual bid functions the rmse of bids declines significantly this is consistent with a reward decision cost model of bidding behavior

are political statements only expressive an experiment abstract many forms of political communication are thought to be expressive rather than instrumental we present evidence suggesting the presence of a perceived instrumental benefit of individual political communication subjects may send a sometimes costly comment on another person s choice of how to donate to two rival political groups subjects who may comment before the choice is made when they may have some persuasive impact are more than twice as likely to comment as those who may only send a message after the decision when the timing of the messages pre or post decision remains fixed but the experimenter alone receives the message there is no difference in the proportion of messages sent pre and post decision moreover most of the comments made to the decision maker prior to the decision use an imperative construction while few do so after the decision is made or when writing to the experimenter alone taken together these results indicate that political expression is both expressive and instrumental

expressive voting and government redistribution testing tullock s charity of the uncharitable models of expressive voting postulate that voters will consume ideological stances on issues by voting for them even when they are against the voter s own narrow selfinterest if the probability of being a decisive voter is low when a voter is unlikely to sway the outcome the odds that avoter will incur any real personal cost a higher tax burden for example from her own expressive vote is small we testand find support for tullock s straightforward empiricalimplication of this model that government welfare transfer payments are inversely related to the probability of being thedecisive voter

policies and market factors driving wind power development in the united states abstract in the united states there has been substantial recent growth in wind energy generating capacity with growth averaging 24 percent annually during the past five years about 1700 mw of wind energy capacity was installed in 2001 while another 410 mw became operational in 2002 during 2003 development activity has remained strong with an estimated 1600 mw of capacity installed with this growth an increasing number of states are experiencing investment in wind energy projects currently about half of all states host at least one wind power project this paper explores the key factors at play in the 12 states in which a substantial amount of wind energy capacity has been developed or planned some of the factors that are examined include policy drivers such as renewable portfolio standards rps federal and state financial incentives as well as market drivers such as consumer demand for green power natural gas price volatility and wholesale market rules

estimating the value of wind energy using electricity locational marginal price abstract there is an increasing interest in adding renewables such as wind to electricity generation portfolios in larger amounts as one response to concern about atmospheric carbon emissions from our energy system and the resulting climate change most policies with the aim of promoting renewables e g rps fit do not explicitly address siting issues which for wind energy are currently approached as the intersection of wind resource land control and transmission factors this work proposes the use of locational marginal price lmp the location and time specific cost of electricity on the wholesale market to signal locations where generation can address electricity system insufficiency after an examination of the spatial and temporal behavior of lmp in michigan over the first two years of wholesale market operation this work combines lmp with wind speed data to generate a value metric high value sites in michigan tend to be sites with higher wind speeds with the bulk of value accruing in the fall and winter seasons

social security longevity and moral hazard abstract recently several authors have argued that social security can have positive effects on savings and welfare when individuals possess hidden information about their longevity that is when there is adverse selection in annuity markets this paper considers the related problem of the effects of social security when individuals can take hidden actions to affect their longevity that is when there is moral hazard in annuity markets in contrast to the adverse selection models we show that social security never raises welfare in a pure moral hazard economy as well social security may either increase or reduce longevity depending on the characteristics of the health related goods consumed it is suggested that a complete analysis of social security needs to consider both adverse selection and moral hazard

the behavioural economics of climate change this paper attempts to bring some central insights from behavioural economics into the economics of climate change in particular it discusses i implications of prospect theory the equity premium puzzle and time inconsistent preferences in the choice of discount rate used in climate change cost assessments and ii the implications of various kinds of social preferences for the outcome of climate negotiations several reasons are presented for why it appears advisable to choose a substantially lower social discount rate than the average return on investments it also seems likely that taking social preferences into account increases the possibilities of obtaining international agreements compared to the standard model however there are also effects going in the opposite direction and the importance of sanctions is emphasized

everyone likes a winner an empirical test of the effect of electoral closeness on turnout in a context of expressive voting under instrumental voting closer elections are expected to have higher turnout under expressive voting however turnout may increase with decreasing closeness when voters have a preference for winners an empirical test using data on belgian municipal elections supports this we find that turnout reaches a local maximum when the largest party in the election obtains just over 52 of the seats and then falls supporting the instrumental closeness argument there is however another turning point the presence of a highly dominating party receiving at least two thirds of the votes stimulates turnout despite the fact that dominance implies lower closeness

rational moralists the role of fairness in democratic economic politics in this paper we empirically test for the influence of fairness considerations on the willingness to redistribute income in private and in democratic decisions in contrast to standard explanations of income redistribution our theory takes into account that prices shift decisively as we move from the sphere of private contributions to politics at the polls it is nearly costless to observe social norms therefore we expect individuals to behave more fairly in the political sphere than in the market place we present experimental evidence which is consistent with this hypothesis in distributive struggles social norms moderate the inclination of human beings to behave like gangsters

hiding information in electoral competition abstract we model a two candidate electoral competition in which there is uncertainty about a policy relevant state of the world the candidates receive private signals about the true state which are imperfectly correlated we study whether the candidates are able to credibly communicate their information to voters through their choice of policy platforms our results show that the fact that private information is dispersed between the candidates creates a strong incentive for them to bias their messages toward the electorate s prior information transmission becomes more difficult the less correlated are the candidates signals the lower is the signals quality and the stronger is the electorate s prior indeed for weak priors welfare decreases as the prior becomes stronger and welfare always decreases as the signals become less correlated

the market value of variable renewables the effect of solar wind power variability on their relative price this paper provides a comprehensive discussion of the market value of variable renewable energy vre the inherent variability of wind speeds and solar radiation affects the price that vre generators receive on the market market value during windy and sunny times the additional electricity supply reduces the prices because the drop is larger with more installed capacity the market value of vre falls with higher penetration rate this study aims to develop a better understanding on how the market value with penetration and how policies and prices affect the market value quantitative evidence is derived from a review of published studies regression analysis of market data and the calibrated model of the european electricity market emma we find the value of wind power to fall from 110 of the average power price to 50 80 as wind penetration increases from zero to 30 of total electricity consumption for solar power similarly low value levels are reached already at 15 penetration hence competitive large scale renewable deployment will be more difficult to accomplish than as many anticipate

old age longevity and mortality contingent claims this paper analyzes the savings and longevity impacts of mortality contingent claims defined here as income measures such as annuities and life insurance under which earned income is contingent on the length of one s life the postwar increase in mandatory annuity and life insurance programs as well as the rapid increase in the life expectancy of older ages motivates a better understanding of the incentive effects that mortality contingent claims have on longevity related behavior we claim that these incentives in often alter the standard conclusions obtained about old age support when mortality is treated exogenously in particular we argue that annuities involve moral hazard effects that increase longevity and among other things introduce a positive interaction between public programs for health care and income support for the elderly programs that have grown enormously in developed countries

cost effectiveness of renewable electricity policies we analyze policies to promote renewable sources of electricity a portfolio standard rps raises electricity prices and primarily reduces gas fired generation a knee of the cost curve exists between 15 and 20 goals for 2020 in our central case and higher natural gas prices lower the cost of greater reliance on renewables a renewable energy production tax credit lowers electricity price at the expense of taxpayers which limits its effectiveness in reducing carbon emissions and it is less cost effective at increasing renewables than a portfolio standard neither policy is as cost effective as a cap and trade policy for achieving carbon emission reductions

the monthly food stamp cycle shooping frequency and food intake decisions in an endogenous switching regression framework mean food spending by food stamp households peaks sharply in the first three days after benefits are received for those who conduct major grocery shopping trips only once per month 42 of all food stamp households mean food energy intake drops significantly by the fourth week of the month for the remaining households intake remains steady over the course of the month these patterns motivate an empirical model that simultaneously accounts for the shopping frequency and food intake decisions over time results have implications for policies that may affect the frequency of grocery shopping by food stamp households

language and government coordination an experimental study of communication in the announcement game one of the key roles of government is to coordinate the activities of citizens one reason why governments are efficient facilitators of coordinated action in addition to their ability to force compliance or tax is that they are typically endowed with more information than the individuals they govern this advantage creates a dilemma for them however since it forces them to decide on how they should distribute the information in their possession to the population this paper investigates this question we investigate the announcement game defined by the government and those it governs and focus on communication strategy that government uses to communicate private information to the citizens this communication strategy involves 1 partitioning the state space in an attempt to mask the true state of the world and 2 choosing what type of language to use in order to communicate elements of this partition we present evidence that the language used to execute a communication strategy does affect the efficiency of the equilibrium convergence process and also demonstrate that subjects playing the role of the government exhibit a great deal of sophistication in the communication strategies they employ and the language they use to execute them

moral bias in large elections theory and experimental evidence in this article we provide evidence that voters in large elections tend to vote against their material self interest and to vote for a morally or ethically appealing alternative it may seem puzzling that voters might behave differently in small elections than they do in large ones however we show that such behavior is a logical consequence of voters having a conflict between obtaining a better material outcome and choosing a moral action we develop a simple model of this conflict and show that decreasing the probability that a single vote is decisive i e pivot probability reduces the importance of outcomes relative to actions in voter decision making because pivot probability is generally small in large elections alternatives that are understood by voters to be morally superior are more likely to win in large elections than in small ones thus compared to the preferences of voters election results will be biased in favor of moral alternatives 1 the model produces a set of predictions that we test in a laboratory experiment to clarify ideas consider a situation in which two outcomes are possible a and b assume that b gives

an experimental study of expressive voting in this paper we report results of an initial attempt to test the theory of expressive voting our experiment involves requiring subjects to vote between receiving a in cash or having b donated to charity on their behalf across subjects we vary the probability that their vote will decide which disbursement is made as the probability of being decisive is lowered the opportunity cost of giving expression to charitable sentiment decreases hence the likelihood of voting in accordance with such sentiment is expected to increase we find weak support for the hypothesis but the results do not replicate when we alter the parameter settings limitations of our design are discussed

strategic information revelation in fundraising abstract we consider a model of voluntary contributions for a public project with random number of potential contributors the fundraiser who observes this number has to decide whether to reveal or suppress the information before contributions are given the fundraiser s objective is to collect maximal contributions we show that whether the public project is convex or non convex can be the key to the fundraiser s announcement decision in the convex case this number is always revealed in the non convex case the number may not be revealed at all or sometimes revealed only when it is in an intermediate range in the presence of multiple equilibria total contributions increase with the extent of concealment

when votes are words not deeds some evidence from the nuclear freeze referendum according to our empirical results voting patterns in the nfr were consistent with the central thesis of an expressive model that moral expression dominates consequentialist behavior when choice is costless while consequentialist theory would predict that owners of capital would favor nuclear weapons capital owners could afford to vote contrary to their interests and in line with common morality because the costs of moral expression in the nfr were so low just as the capital ownership variables do not work in the direction predicted by our consequentialist model neither does income does this mean that wealthy voters cast votes diametrically opposed to their self interest not at all the expressive model contends that when voting is costless people do not have interests but rather moral judgments which now cost very little to express indeed when votes involve words not even individuals interests in government expenditure can be detected

follow the leader theory and evidence on political participation using state by state voting data for u s presidential elections the authors observe that voter turnout is a positive function of predicted closeness to explain the strategic component of political participation they develop a follow the leader model political leaders expend effort according to their chance of being pivotal which depends on the expected closeness of the race at both state and national levels and how voters respond to their effort structural estimation supports this model for example a 1 percent increase in the predicted closeness at the state level stimulates leaders efforts which increases turnout by 0 34 percent

de centralization and voter turnout theory and evidence from german municipalities a vast academic literature illustrates that voter turnout is affected by the institutional design of elections e g compulsory voting electoral system postal or sunday voting in this article we exploit a simple downsian theoretical framework to argue that the institutional framework of public good provision and in particular the distribution of political and administrative competences across government levels likewise affects voters turnout decisions by influencing the expected net benefit of voting empirically we exploit the institutional variation across german municipalities to test this proposition and find supportive evidence

economics food choices and nutrition abstract our goal in this paper is to examine the role and influence of economic factors defined rather broadly on consumer food choices and hence nutritional outcomes we attempt to do this in a non technical fashion we examine the role of prices especially as they relate to the affordability of food in the united states and as a policy lever income is analyzed as a driving force behind changes in eating habits in particular increasing the demand for convenience the role of time constraints as well as time preference are examined as links to healthy eating habits and as forces behind current trends in eating patterns information and knowledge are given prominent play as counter balances to economic forces driving eating habits we conclude with and examination into maternal nutrition knowledge and children s dietary quality

voting when money and morals conflict an experimental test of expressive voting abstract moral considerations may matter much in voting because the costs of expressing support for a morally worthy cause may be low in a referendum these costs depend on whether a voter expects to affect the outcome of the referendum to test the low cost theory of expressive voting we experimentally investigate a proposal to tax everyone and to donate tax revenues the analysis of expectations and voting decisions shows that the low cost theory fails to explain voting decisions instead we find that voters tend to approve of the proposal if they expect others to approve too

schooling health knowledge and obesity the connection between schooling and health is well documented an important empirical issue that needs to be examined however is whether schooling s effects are due to individual health knowledge differences this empirical study examines this issue with an increasingly important health indicator obesity since provision of health knowledge is a major tool of public agencies promoting health this empirical study uses a new direct measure of health knowledge to test this hypothesis the results show that knowledge is inversely related to the probability that an individual is obese schooling s effects on relative weight and the probability of being obese are explained by differences in knowledge this result may imply that schooling s effect on the allocative efficiency of the household production of health is the main reason schooling is linked to health behaviour the result also may imply that the most effective method of health education is to highlight the disease element of poor dietary habits a

the job generation impacts of expanding industrial cogeneration sustainable economic development requires the efficient production and use of energy combined heat and power chp offers a promising technological approach to achieving both goals while a recent u s executive order set a national goal of 40 gw of new industrial chp by 2020 the deployment of chp is challenged by financial regulatory and workforce barriers discrepancies between private and public interests can be minimized by policies promoting energy based economic development in this context a great deal of rhetoric has addressed the ambiguous goal of growing green jobs our research provides a systematic evaluation of the job impacts of an investment tax credit that would subsidize industrial chp deployment we introduce a hybrid analysis approach combining simulations using the national energy modeling system with input output modeling nems simulates general equilibrium effects including supply and demand side resources we identify first order employment impacts by creating bill of goods expenditures for the installation and operation of industrial chp systems second order impacts are then estimated based on the redirection of energy bill savings accruing to consumers these include jobs across the economy created by the lower electricity prices that would result from increased reliance on energy efficient chp systems on a jobs per gwh basis we find that the second order impacts are approximately twice as large as the first order impacts

are hypothetical referenda incentive compatible a comment in a recent article in this journal cummings al 1997 offer experimental evidence rejecting the hypothesis that a hypothetical referendum is an incentive compatible mechanism for obtaining the social value of or willingness to pay for changes in the allocation of environmental goods and services while cautions in offering a blanket rejection of hypothetical referenda as a means of measuring economic values on the basis of their findings the authors do suggest that at least in experimental settings respondents appear to behave differently when real money is changing hands wheather hypothetical situations adequately mimic real market situations has been debated in the contigent valuation literature since its inception see cummings brookshire and schulze 1986 cummings et al s finding of incentive incompatibility appears to offer strong evidence for the critics of hypothetical referenda

system friendly wind power how advanced wind turbine design can increase the economic value of electricity generated through wind power abstract previous studies find that the economic value of electricity usd mwh generated by wind power drops with increasing market share different measures can help mitigate the value drop including electricity storage flexible conventional plants expansion of transmission and demand response this study assesses another option a change in design of wind power plants advanced wind turbines that are higher and have a larger rotor compared to rated capacity lower specific rating generate electricity more constantly than classical turbines recent years have witnessed a significant shift towards such advanced technology our model based analysis for northwestern europe shows that such design can substantially increase the spot market value of generated electricity at a 30 penetration rate the value of 1 mwh of electricity generated from a fleet of advanced turbines is estimated to be 15 higher than the value of 1 mwh from classical turbines the additional value is large whether compared to wind generation costs to the value drop or to the effect of alternative measures such as electricity storage extensive sensitivity tests indicate that this finding is remarkably robust the increase in bulk power value is not the only advantage of advanced turbines additional benefits might accrue from reduced costs for power grids and balancing services to fully realize this potential power markets and support policies need to be appropriately designed and signal scarcity investors
