does employment protection create its own political support this paper investigates the ability of employment protection to generate its own political support a version of the mortensen pissarides model is used for this purpose if wages are set through nash bargaining workers value employment protection because it strengthens their hand in wage negotiations workers in high productivity matches benefit most from higher wages as they expect to stay employed for longer by reducing turnover employment protection shifts the distribution of match specific productivity toward lower values thus stringent protection in the past actually reduces support for employment protection today introducing involuntary separations reverses this conclusion now workers value employment protection because it delays involuntary dismissals workers in low productivity matches gain most since they face the highest risk of dismissal the downward shift in the productivity distribution is now a shift towards supporters

political support and tax reforms with an application to italy in 2001 the italian government introduced a personal income tax reform to be implemented in successive phases in 2004 taxes were reduced to all income levels with higher gains for low income and high income individuals than for middle income ones a large debate arised this paper explores the political economy reasons under this tax reform mainly the attempt of the government to attract the uncertain voters swing voters a probabilistic voting model is introduced to capture the importance of swing voters the model predicts that the average personal income tax rate tends to be lower for groups of lower income higher preference for leisure and containing more politically mobile voters swing voters however data from italian polls show that while the tax reform was a good strategy to attract swing voters the specific design of the reform which favored high income and low income individuals but not the middle class was not the more appropriate strategy

electoral outcomes with probabilistic voting and nash social welfare maxima abstract this paper provides unexpected support to nash s view of how bargaining determines the social choice we first present a spatial model of electoral competition with probabilistic voting and a very close relation between voters preferences and their choice probabilities the outcome of the electoral competition game is then shown to be precisely the social alternative that maximizes a nash type social welfare function theorem 1 this electoral outcome is also interpreted as a unanimity likelihood maximum corollary 1 within our framework existence and uniqueness of such an outcome are guaranteed corollaries 2 and 3

the need for enemies we develop a model where some politicians have an edge in undertaking a task and this gives them electoral advantage creating an incentive to underperform in the task we test the empirical implications in the context of fighting against insurgents using colombian data the main prediction is that large defeats for the insurgents reduce the probability that these politicians fight them especially in electorally salient places we find that after the largest victories against farc rebels the government reduced its counterinsurgency efforts especially in politically important municipalities politicians need to keep enemies alive in order to maintain their political advantage

alfred marshall lecture social capital as good culture to explain the extremely long term persistence more than 500 years of positive historical experiences of cooperation putnam 1993 we model the intergenerational transmission of priors about the trustworthiness of others we show that this transmission tends to be biased toward excessively conservative priors as a result societies can be trapped in a low trust equilibrium in this context a temporary shock to the return to trusting can have a permanent effect on the level of trust we validate the model by testing its predictions on the world values survey data and the german socio economic panel we also present some anecdotal evidence that these priors are reflected in novels that originate in different parts of the country jel 04 016 043 p16

redistribution policy and the expansion of the public sector abstract during the first part of this century life cycle and insurance type considerations seem to have dominated redistribution policy in particular when we look at the consequences for the expansion of public spending by contrast during recent decades fragmented horizontal redistributions between various minority groups have probably been the most important mechanisms the self interest of different groups of the electorate seems to have provided the most powerful motive behind these various policies although welfare altruism and what in this paper are called considerations of consequential externalities have probably been important motives behind redistribution in favor of the poor

representative democracy and marginal rate progressive income taxation abstract this paper develops a political economy model that is consistent with the fact that democracies have a preference for increasing marginal tax rates on income we present a model in which there is an exogenous set of political parties with preferences over the set of admissible tax schedules this set contains virtually any increasing and piecewise linear continuous function each party decides whether or not to present a candidate for election there is a fixed cost of running the elected candidate implements one of her preferred tax policies our main results provide conditions under which a strong nash equilibrium exists and a tax schedule with increasing marginal tax rates is implemented in some nash equilibria and in any strong nash equilibrium

transparency and economic policy we provide a two period model of political competition in which voters imperfectly observe the electoral promises made to other voters imperfect observability generates an incentive for candidates to offer excessive transfers even if voters are homogeneous and taxation is distortionary government spending is larger than in a world of perfect observability transfers are partly financed through government debt and the size of the debt is higher in less transparent political systems the model provides an explanation of fiscal churning it also predicts that groups whose transfers are less visible to others receive higher transfers and that imperfect transparency of transfers may lead to underprovision of public goods from the policy perspective the main novelty of our analysis is a separate evaluation of the transparency of spending and the transparency of revenues we show that the transparency of the political system does not unambiguously improve efficiency transparency of spending is beneficial but transparency of revenues can be counterproductive because it endogenously leads to increased wasteful spending

political competition between differentiated candidates abstract we introduce a framework of electoral competition in which voters have general preferences over candidates immutable characteristics such as gender race or previously committed policy positions as well as their policy positions which are flexible candidates are uncertain about the distribution of voter preferences and choose policy positions to maximize their winning probability we characterize a property of voter utility functions uniform candidate ranking ucr that captures a form of separability between fixed characteristics and policy when voters have ucr preferences candidates equilibrium policies converge in any strict equilibrium in contrast notions like competence or complementarity lead to non ucr preferences and policy divergence in particular we introduce a new class of models that contains the probabilistic voting model as a special case and in which there is a unique equilibrium that generically features policy divergence

openness external risk and volatility implications for the compensation hypothesis a central assumption in the globalization literature is that economic openness generates economic insecurity and volatility based on this assumption schol ars of international political economy have proposed the compensation hypothesis which claims that globalization bolsters rather than undermines the welfare state by increasing public demand for social protection against externally generated eco nomic instability the openness volatility link is dubious however on both theoret ical and empirical grounds in this study i revisit the volatility assumption focusing on a crucial difference between openness and external risk in their effect on volatil ity my statistical analysis of a panel data set from 175 countries 1950 2002 finds a consistent effect of external risk on volatility of the major economic aggregates but a largely insignificant effect of openness these findings suggest that economic volatility may be a mistaken link in explaining the openness spending nexus calling for further research on the causal mechanisms linking the two the general growth of government in the post world war ii era is one of the most important empirical regularities in political science measured by general govern ment consumption or sectoral expenditures government size grew dramatically during most of the postwar period intrigued by this phenomenal government growth political scientists offered numerous accounts some viewing this growth as a corollary of economic phenomena such as modernization industrialization income distribution or fiscal illusion and others attributing government growth to political causes such as bureaucratization interest group politics and electoral competition 1

fiscal federalism and redistributive politics abstract we consider the interaction between redistributive politics at central and local levels in a federal system and characterize the factors influencing success in redistributive politics in both federal and unitary systems we examine how the political characteristics of different states and groups give them better or worse outcomes in a federal system as opposed to a unitary system we examine possibilities of multiple equilibria with divided government between the two layers we analyze the choice between block grants and matching grants we also examine the impact of federalism on the incentives for geographic mobility

interjurisdictional redistribution and public goods with increasing returns to scale this paper builds upon probabilistic voting theory to examine vote maximizing interjurisdictional redistribution with increasing returns to scale in the production of regional public goods we find that with interregional differences in the per capita cost of public goods the vote maximizing interregional redistribution will seem incoherent and unfair when judged on the basis of the availability of public goods or regional incomes

micro targeting and polarization abstract this paper connects the rise in polarization to changes in media technology which allow for higher precision in the advertising strategy of candidates candidates place ads in media outlets whose audiences differ in ideology and size we develop the concept of media centrality which takes into account differences in the media network and in ideology media centrality leads to a simple characterization of both the optimal targeting strategy and policy we show that generally a more fragmented media landscape leads to an increase in polarization

the political intergenerational welfare state abstract using a three period overlapping generations economy framework we characterize an intergenerational welfare state with endogenous education and pension under voting we show that although politically establishing pay as you go payg social security in isolation in a dynamically efficient economy will always reduce the capital investment and therefore the social welfare as expected in contrast politically implementing education pension policy package instead can improve both human and physical capital accumulation and social welfare over laissez faire however for this the political influence of the old has to be small thus limiting the size of the payg social security program

the principle of minimum differentiation holds under sufficient heterogeneity the so called principle of minimum differentiation stated by hotelling has been challenged by many authors this paper restores the principle by showing that n firms locate at the center of the market and charge prices higher than the marginal cost of production when heterogeneity in consumers tastes is large enough

social ideology and taxes in a differentiated candidates framework many observers argue that political polarization particularly on social and cultural issues has increased in the united states how does this influence the political competition on economic issues we analyze this question using a framework in which two officemotivated candidates differ in their fixed ideological position and choose a level of government spending to maximize their vote share in equilibrium candidates cater to a set of swing voters who contain socially conservative and economically liberal voters as well as socially liberal and economically conservative voters we analyze how voters cultural preferences and candidates cultural positions influence equilibrium economic positions jel d72 e62 h50 z13 many observers have argued that polarization between the two major parties in the united states particularly on noneconomic cultural matters has increased this is reflected both at the elite level in particular in congress poole and rosenthal 1984 1985 2000 and among democratic and republican activists and voters abramowitz and saunders 2008 harbridge and malhotra 2011 in the american national election survey respondents report their own ideological position on a scale from 1 very liberal to 7 very conservative the number of respondents who report one of the extreme positions 1 2 6 or 7 has grown from 20 and 21 percent in 1972 and 1976 to 31 and 30 percent in the 2004 and 2008 respectively moreover liberal and conservative voters have become considerably more reliable supporters of democrats and republicans respectively over the last generation 1 if we accept the widespread view that reagan s conservative revolution has created a cultural wedge between the parties that only widened in the 1990s and 2000s what consequences for the parties economic policies should we expect

the right look conservative politicians look better and voters reward it previous research has established that good looking political candidates win more votes we extend this line of research by examining differences between parties on the left and on the right of the political spectrum our study combines data on personal votes in real elections with a web survey in which 2 513 non finnish respondents evaluated the facial appearance of 1 357 finnish political candidates we find that political candidates on the right are better looking in both municipal and parliamentary elections and also have a larger beauty premium in municipal but not in parliamentary elections we discuss possible explanations for these patterns based on the fact that municipal candidates are relatively unknown jel code d72 j45 j70

impacts of network constraints on electricity market equilibrium nash equilibrium is usually used as the solution of generator s strategic bidding in electricity markets the available literature has shown by simulation that multiple market equilibria or no pure equilibrium may be induced after the inclusion of network constraints transmission constraints this paper presents a systematical analysis for the impacts of network constraints on the market equilibrium in oligopolistic electricity markets in our modeling the independent system operator iso dispatches generation and determines nodal prices via solving an optimal power flow opf and the individual generator optimizes its submitted supply function with nash supply function equilibrium sfe strategy after taking into account iso s decision making process on dispatched generations and nodal prices the conditions for the existence of equilibrium are given and it is shown that there may be multiple equilibria or no pure nash equilibrium the equilibrium if it exists will be at a point where generators pay no congestion charge

the provision of public goods under alternative electoral incentives politicians who care about the spoils of office may underprovide a public good because its benefits cannot be targeted to voters as easily as pork barrel spending we compare a winner take all system where all the spoils go to the winner to a proportional system where the spoils of office are split among candidates proportionally to their share of the vote in a winner take all system the public good is provided less often than in a proportional system when the public good is particularly desirable we then consider the electoral college system and show that it is particularly subject to this inefficiency

the slave trade and the origins of mistrust in africa in a recent study nunn 2008 examines the long term impacts of africa s slave trade he finds that the slave trade which occurred over a period of more than 400 years had a significant negative effect on long term economic development although the article arguably identifies a negative causal relationship between the slave trade and income today the analysis is unable to establish the exact causal mechanisms underlying this reduced form relationship in this article we examine one of the channels through which the slave trade may affect economic development today combining contemporary individual level survey data with historical data on slave shipments by ethnic group we ask whether the slave trade caused a culture of mistrust to develop within africa initially slaves were captured primarily through state organized raids and warfare but as the trade progressed the environment of ubiquitous insecurity caused individuals to turn on others including friends and family members and to kidnap trick and sell each other into slavery sigismund wilhelm koelle 1854 p e h hair 1965 charles piot 1996 we hypothesize that in this environment a culture of mistrust may have evolved which may persist to this day we show that current differences in trust levels within africa can be traced back to the transatlantic and indian ocean slave trades combining contemporary individual level survey data with historical data on slave shipments by ethnic group we find that individuals whose ancestors were heavily raided during the slave trade are less trusting today evidence from a variety of identification strategies suggests that the relationship is causal examining causal mechanisms we show that most of the impact of the slave trade is through factors that are internal to the individual such as cultural norms beliefs and values jel j15 n57 z13

inherited trust and growth this paper develops a new method to uncover the causal effect of trust on economic growth by focusing on the inherited component of trust and its time variation we show that inherited trust of descendants of us immigrants is sig nificantly influenced by the country of origin and the timing of arrival of their forebears we thus use the inherited trust of descendants of us immigrants as a time varying measure of inherited trust in their country of origin this strategy allows to identify the sizeable causal impact of inherited trust on worldwide growth during the twentieth century by controlling for country fixed effects jel n11 n12 n31 n32 o47 z13

dynamic convexification within nested benders decomposition using lagrangian relaxation an application to the strategic bidding problem abstract many decomposition algorithms like benders decomposition and stochastic dual dynamic programming are limited to convex optimization problems in this paper we utilize a dynamic convexification method that makes use of lagrangian relaxation to overcome this limitation and enables the modeling of non convex multi stage problems using decomposition algorithms though the algorithm is confined by the duality gap of the problem being studied the computed upper bounds for maximization problems are at least as good as those found via a linear programming relaxation approach we apply the method to the strategic bidding problem for a hydroelectric producer in which we ask what is the revenue maximizing production schedule for a single price maker hydroelectric producer in a deregulated bid based market because the price maker s future revenue function has a sawtooth shape we model it using mixed integer linear programming to remedy the non concavity issues associated with modeling the future revenue function as a mixed integer linear program we model the price maker s bidding decision utilizing both benders decomposition and lagrangian relaxation we demonstrate the utility of our algorithm through an illustrative example and through three case studies in which we model electricity markets in el salvador honduras and nicaragua

which dimensions of culture matter for long run growth we present empirical evidence that among a variety of cultural dimensions the individualism collectivism dimension based on hofstede s 2001 data is the most important and robustly significant effect of culture on long run growth other dimensions that have a significant effect albeit less robust are generally strongly correlated with individualism and convey similar information we found no significant or robust effect on growth from cultural dimensions that are independent from the individualism collectivism cleavage

a volatility based theory of fiscal union desirability abstract heterogeneous countries may rationally choose to form a currency union first and a fiscal union later we find and illustrate empirically for the emu countries reasonable volatility conditions under which this sequencing in the deepening process is indeed rationalizable changes in the distribution of expected income shocks require a reassignment of political weights to restore unanimous support for an added fiscal dimension the bargaining space depends on countries relative income size and cross correlation of shocks

the protestant fiscal ethic religious confession and euro skepticism in germany during the european sovereign debt crisis most countries that ran into fiscal trouble had catholic majorities whereas countries with protestant majorities were able to avoid fiscal problems we find that christian conservative members of the german parliament from constituencies with higher shares of protestants were more likely to vote against a third bailout for greece survey data show that views on the euro differ between german protestants and non protestants at the individual level too among protestants concerns about the euro have compared to non protestants increased during the crisis we show that this increase in concern is linked to a reduction of protestants subjective well being we use the timing of survey interviews and news events in 2011 to account for the endogeneity of euro concerns emphasis on moral hazard concerns in protestant theology may thus still shape economic preferences jel d72 e00 i31 z12

the size and scope of government comparative politics with rational politicians we try to demonstrate how economists may engage in research on comparative politics relating the size and composition of government spending to the political system a downsian model of electoral competition and forward looking voting indicates that majoritarian as opposed to proportional elections increase competition between parties by focusing it into some key marginal districts this leads to less public goods less rents for politicians more redistribution and larger government a model of legislative bargaining and backward looking voting indicates that presidential as opposed to parliamentary regimes increase competition between both politicians and voters this leads to less public goods less rents for politicians less redistribution and smaller government we confront these predictions with cross country data from around 1990 controlling for economic and social determinants of government spending we nd strong and robust support for the prediction that the size of government is smaller under presidential regimes and weaker support for the prediction that majoritarian elections are associated with less public goods

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

balanced budget redistribution as the outcome of political competition this paper models balanced budget redistribution between socio economic groups as the outcome of electoral competition between two political parties equilibrium is unique in the present model and a sufficient condition for existence is given requiring that there be enough stochastic heterogeneity with respect to party preferences in the electorate the validity of hotelling s principle of minimum differentiation and of director s law are examined under alternative hypotheses concerning administrative costs of redistributions and voter s possibilities both of abstaining from voting and of becoming campaign activists for one of the parties the policy strategy of expected plurality maximization is contrasted with the strategy of maximizing the probability of gaining a plurality incomes are fixed and known so lump sum taxation is feasible however constraints on tax transfer differentiation between individuals are permitted in the analysis

property rights and the political organization of agriculture we propose a general equilibrium model where the economic organization of agriculture and the political equilibrium determining the security of property rights are jointly determined in particular because the form of organization may affect the probability and distribution of benefits from future property challenges it may be shaped in anticipation of this impact property rights security may then be secured at the expense of economic efficiency the model provides a framework for understanding why in some contexts land is redistributed primarily via land sales and tenancy markets but via politics and conflict in others we test some implications of the theory using a five decade panel dataset that traces changes in the extent of tenancy and tenancy reform across 15 indian states

the instructional use and teaching preparation of graduate students in u s ph d granting economics departments graduate students are employed extensively in the teaching of economics at the undergraduate level but little is known about how they are used for instruction and how they are prepared for their teaching duties to investigate this topic we prepared a survey and sent it to the chairs of all 100 ph d granting economics departments the survey was designed to elicit information on i the size of ph d economics programs and the uses of graduate students for undergraduate instruction ii the provision of credit and noncredit courses in teaching for economics graduate student instructors iii teaching programs for international graduate students serving as economics instructors and iv the uses of teaching evaluation for graduate student instructors in economics two members of the aea committee on economic education reviewed initial drafts of the survey several economists with extensive experience in survey work and the teaching preparation of economics graduate students also provided constructive criticism it underwent five revisions before it was sent to department chairs via regular mail in mid august 2002 we received 85 of 100 surveys mailed this high response rate was achieved through two follow up mailings to nonresponding chairs and by assuring all respondents that only the aggregate findings would be reported the response rate was also high across departments regardless of research ranking see thursby 2000 it was 88 percent for the top third of departments 97 percent for the middle third and 71 percent for the lowest third the higher response rate for the middle third is probably because more graduate students teach at these mostly large public universities the lower response rate for the bottom third departments reflects some difficulty in contacting their chairs but it might also indicate less activity to report

redistributive politics and economic efficiency the political process often compensates the losers from technical change or international competition in an economically inefficient way namely by subsidizing or protecting declining industries instead of encouraging the movement of resources to other more productive uses we find that a dynamic inconsistency in the game of redistributive politics contributes to this outcome to achieve economically efficient outcomes it is necessary that those making economically inefficient choices not be given offsetting transfers but the political process distributes income on the basis of political characteristics which are in general different from the economic characteristics that are rewarded by the market we identify circumstances in which the inefficient choosers have desirable political characteristics and are therefore immune from threats of having to face the economic consequences of their choices

the hidden cost of raising voters expectations reference dependence and politicians credibility abstract two politicians compete to get elected each politician is characterized by a valence which is unobservable to the electorate and can take one of two values high or low the representative voter prefers politicians with high valence but random shocks may lead him to appoint a low valence politician politicians make statements concerning their valence if the voter is a standard expected utility maximizer politicians statements lack any credibility and no information transmission takes place by introducing reference dependence and loss aversion we show that truthful communication is possible in equilibrium and we characterize the conditions under which it can arise intuitively these behavioral biases introduce a cost of overstating one s valence as overstatements may shift the electorate s preferences toward better skilled opponents

budget deficits and redistributive politics this paper proposes a new view of the forces in the political process that cause governments to accumulate debt the analysis builds on a model of redistributive politics that contrary to median voter models does not restrict the set of policies that politicians can propose i show that deficits occur even in an environment where voters and periods are homogeneous this is an environment where previous political theories of debt would predict budget balance in the model deficits are a way for candidates to better target promises to voters and are therefore used as tools of redistributive politics the main contribution of the analysis is to show that the same forces that push candidates to redistribute resources across voters to pursue political advantage are forces that generate budget deficits most countries have sizeable national debts indeed thinking of governments as debtors seems so customary that it feels awkward to talk about a national credit this suggests that there are systematic forces pushing governments to regularly borrow to cover the excess of spending over receipts at the same time a significant amount of government spending consists of transfers to special interest groups that are hard to justify on efficiency or equity grounds this paper presents a political economic model that suggests that these two phenomena are connected debt is at least in part caused by the fact that in order to get elected candidates need to appeal to groups of voters with promises of transfers debt allows candidates a finer control over the promises they make to these groups

pareto optimality of policy proposals with probabilistic voting this paper studies the pareto optimality properties of policy proposals and electoral outcomes when there is probabilistic voting theorem 1 proves that when the position of one candidate is taken as fixed the other candidate will propose a pareto optimal alternative this implies that whenever there is an electoral equilibrium in pure strategies the electoral outcome is pareto optimal it also implies that even if there is no such equilibrium the electoral outcomes from a sequence of elections will be pareto optimal except possibly for an initial status quo

identifying the effect of unemployment on crime abstract in this paper we analyze the relationship between unemployment and crime using u s state data we estimate the effect of unemployment on the rates of seven felony offenses we control extensively for state level demographic and economic factors and estimate specifications that include state specific time trends state effects and year effects in addition we use prime defense contracts and a state specific measure of exposure to oil shocks as instruments for unemployment rates we find significantly positive effects of unemployment on property crime rates that are stable across model specifications our estimates suggest that a substantial portion of the decline in property crime rates during the 1990s is attributable to the decline in the unemployment rate the evidence for violent crime is considerably weaker however a closer analysis of the violent crime of rape yields some evidence that the employment prospects of males are weakly related to state rape rates

the role of social capital in financial development to identify the effect of social capital on financial development we exploit social capital differences within italy in high social capital areas households are more likely to use checks invest less in cash and more in stock have higher access to institutional credit and make less use of informal credit the effect of social capital is stronger where legal enforcement is weaker and among less educated people these results are not driven by omitted environmental variables since we show that the behavior of movers is still affected by the level of social capital of the province where they were born

views of teaching and research in economics and other disciplines anecdotes are often quite suggestive a graduate student in economics who was serving as a teaching assistant once reported that his major professor came into his office and told him that he was spending too much of his time helping his undergraduate students and not enough time on his research was the professor expressing a preference for time spent on teaching over research or was the professor suggesting to the student that the academic market rewards research more than teaching regardless the underlying message that gets transferred from such an experience as early as graduate education and perhaps throughout a career is that teaching is not as important or valuable as research such strong conclusions however should not be based on anecdotal evidence whether economics professors are less interested in teaching and more interested in research is an empirical question worthy of study although teaching and research choices made by economics faculty members reflect both preferences and choice sets in this study we focus on preferences and use a national survey to compare the teaching and research views of economists with faculty members in other major disciplines

transaction analysis in deregulated power systems using game theory the electric power industry is in transition to a deregulated marketplace for power transactions in this environment all power transactions are made based on price rather than cost a regional power pool is noted as the most straightforward path to a deregulated electricity marketplace however many questions remain unanswered regarding the economics of power pool participation in a deregulated energy marketplace participants are interested in maximizing their own profits regardless of the system wide profits it is perceived that competition will reduce the price of electricity for retail customers however the key issue for participants is related with the price definition to remain competitive in this paper the authors use game theory to simulate the decision making process for defining offered prices in a deregulated environment the outcome of this study may be used by power pool coordinators to discourage unfair coalitions a modified ieee 30 bus power system is used as a deregulated power pool to illustrate the main features of the proposed method

cultural differences and institutional integration if citizens of different countries belonging to an economic union adhere to different and deeply rooted cultural norms when these countries interact they may find it impossible to agree on efficient policies especially in hard times political leaders are bound to follow policies that do not violate their country s cultural norms this paper provides a simple positive theory and a compelling case study of the euro area crisis to highlight the importance of cultural clashes when economies integrate we also provide a normative argument about the desirability of institutional integration a political union with a common enforcement agency is the more beneficial the greater is cultural diversity in an economic union

computing all nash equilibria of multiplayer games in electricity markets by solving polynomial equations the analysis of the nash equilibrium ne in electricity markets with imperfect competition is subject to two major challenges the treatment of multiplayer games and the determination of the existence of multiple market equilibria to resolve these obstacles a solution method based on the payoff matrix approach and polynomial equations is proposed in this paper to calculate all the nash equilibria of multiplayer games in the electricity markets first the proposed method decomposes the game by means of a set of all pure strategies assigned with positive probabilities support for each possible support the ne condition can be characterized by a set of polynomial equations with inequality constraints next the homotopy continuation algorithm is employed to obtain all solutions of the polynomial system finally all nash equilibria can be found by verifying each solution of all polynomial systems two example systems one involving the cournot model and the other based on the supply function equilibrium sfe model are applied to test the proposed method respectively the results show that the proposed method has the ability to identify all ne under certain conditions indicating that the proposed algorithm is useful for providing insights into the theoretical analysis of electricity markets

an individual welfare maximization algorithm for electricity markets an algorithm that allows a market participant to maximize its individual welfare in electricity spot markets is presented the use of the algorithm in determining market equilibrium points called nash equilibria is demonstrated the start of the algorithm is a spot market model that uses the optimal power flow opf with a full representation of the transmission system and inclusion of consumer bidding the algorithm utilizes price and dispatch sensitivities available from the hessian matrix and gradient of the opf to help determine an optimal change in an individual s bid the algorithm is shown to be successful in determining local welfare maxima and the prospects for scaling the algorithm up to realistically sized systems are very good nash equilibria are investigated assuming all participants attempt to maximize their individual welfare this is done by iteratively solving the individual welfare maximization algorithm until all individuals stop modifying their bids

the monopoly of violence evidence from colombia many states in latin america africa and asia lack the monopoly of violence even though this was identified by max weber as the foundation of the state and thus the capacity to govern effectively in this paper we develop a new perspective on the establishment of the monopoly of violence we build a model to explain the incentive of central states to eliminate nonstate armed actors paramilitaries in a democracy the model is premised on the idea that paramilitaries may choose to and can influence elections since paramilitaries have preferences over policies this reduces the incentives of the politicians they favor to eliminate them we then investigate these ideas using data from colombia between 1991 and 2006 we first present regression and case study evidence supporting our postulate that paramilitary groups can have significant effects on elections for the legislature and the executive next we show that the evidence is also broadly consistent with the implication of the model that paramilitaries tend to persist to the extent that they deliver votes to candidates for the executive whose preferences are close to theirs and that this effect is larger in areas where the presidential candidate would have otherwise not done as well finally we use roll call votes to illustrate a possible quid pro quo between the executive and paramilitaries in colombia language en

the effects of party competition on budget outcomes empirical evidence from local governments in spain this paper investigates the link between local budget outcomes and the intensity of party competition measured as the margin of victory obtained by the incumbent in the previous local election i e the difference between the vote share and 50 two competing hypotheses are tested in the paper on the one hand the leviathan government hypothesis suggests that the lower the intensity of party competition is the greater is the increase in the size of the local public sector irrespective of the ideology of the party in power on the other hand the partisan government hypothesis suggests that the incumbent will find it easier to advance its platform when intensity of competition is low i e parties on the left right will increase decrease the size of the local public sector when the intensity of the challenge from the opposition is low these hypotheses are tested with information on spending own revenues and deficit for more than 500 spanish local governments over 8 years 1992 1999 and information on the results of two local electoral contests 1991 and 1995 the evidence favors the partisan hypothesis over the leviathan one we found that for left wing governments spending taxes and deficits increased as the electoral margin increases whereas for right wing governments a greater margin of victory led to reductions in all these variables

shrouded costs of government the political economy of state and local public pensions abstract why do public sector workers receive so much of their compensation in the form of pensions and other benefits this paper presents a political economy model in which politicians compete for taxpayers and government employees votes by promising compensation packages but some voters cannot evaluate every aspect of promised compensation if pension packages are shrouded so that public sector workers better understand their value than ordinary taxpayers then compensation will be highly back loaded in equilibrium the welfare of public sector workers could be improved holding total public sector costs constant if they received higher wages and lower pensions centralizing pension determination has two offsetting effects on generosity more state level media attention helps taxpayers better understand pension costs and that reduces pension generosity but a larger share of public sector workers will vote within the jurisdiction which increases pension generosity a short discussion of pensions in two decentralized states california and pennsylvania and two centralized states massachusetts and ohio suggests that centralization appears to have modestly reduced pensions but as the model suggests this is unlikely to be universal

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

the political economy of intergovernmental grants evidence from a maturing democracy we evaluate the impact of political forces in the allocation of intergovernmental grants in portugal as it matured from a young to an established democracy using a large and unexplored dataset we show that political variables condition the granting system and that their importance changed over time while tactical manipulation in the distribution of grants among municipalities seems to exist only in the early years of democracy opportunistic effects are stronger in the latter years we argue that the latter effect is due to a change in the political environment and to the electorate s lack of information on intergovernmental grants

solving three player games by the matrix approach with application to an electric power market in models of imperfect competition of deregulated electricity markets the key task is to find the nash equilibrium ne the approaches for finding the ne have had two major bottlenecks computation of mixed strategy equilibrium and treatment of multiplayer games this paper proposes a payoff matrix approach that resolves these bottlenecks the proposed method can efficiently find a mixed strategy equilibrium in a multiplayer game the formulation of the ne condition for a three player game is introduced and a basic computation scheme of solving nonlinear equalities and checking inequalities is proposed in order to relieve the inevitable burden of searching the subspace of payoffs several techniques are adopted in this paper two example application problems arising from electricity markets and involving a cournot and a bertrand model respectively are investigated for verifying the proposed method the proposed method outperforms a publicly available game theory software for the application problems

intergenerational altruism with future bias abstract we show that standard preferences of altruistic overlapping generations exhibit future bias which involves preference reversals associated with increasing impatience this underlies a conflict of interest between successive generations we explore the implications of this conflict for intergenerational redistribution when there is a sequence of utilitarian governments representing living generations and choosing policies independently over time we argue that future bias creates incentives to legislate and sustain a pay as you go pension system which every government views as a self enforcing commitment mechanism to increase future old age transfers

teaching economics at the start of the 21st century still chalk and talk in spring 2000 we conducted a national survey of academic economists to determine how economics is taught in four different types of undergraduate courses principles intermediate theory statistics and econometrics and other upper division courses at institutions in the five carnegie classifications research doctoral master s baccalaureate and associate as listed in a classification of institutions of higher education 1994 edition this new survey replicates our 1995 survey becker and watts 1996 therefore we can compare the results from the two surveys to document changes in teaching methods as well as the related academic issues that were addressed in the background information section of the surveys a key reason for believing that teaching methods might have changed during this period was the sharp decrease in economics enrollments during the early 1990 s becker 1997 john siegfried and david k round 2001 as we have documented elsewhere becker and watts 1998 there is evidence that economists are less likely to use non lecture teaching methods than instructors in other fields and that students rate economics instructors somewhat lower than they rate other instructors changing teaching methods and increasing the importance of teaching within economics departments in response to falling enrollments is therefore a plausible and endogenous response for faculty members and departments concerned about losing resources furthermore there is at least circumstantial evidence that economists are devoting more attention to teaching than in the recent past becker 2000 since our 1995 survey several books have been published to illustrate how economists can use a wide range of alternative teaching methods in undergraduate courses e g becker and watts 1998 william walstad and philip saunders 1998 other books have appeared focusing on specific teaching methods such as using classroom experiments spreadsheet applications or active learning and cooperative learning assignments e g diane keenan and mark h maier 1995 tod s porter and teresa riley 1995 theodore bergstrom and john h miller 1997 denise hazlett 1999 becker 2000 documents the increase in aea sessions devoted to teaching economics at the annual meetings of the allied social sciences association during the mid 1990 s at the 1998 2000 allied social sciences association assa meetings the number of sessions devoted to teaching economics ranged from 11 to 14 and presented sessions dealt with such topics as teaching economics in the transition economies chaired by world bank chief economist joseph stiglitz a retrospective on nobel laureate paul samuelson s principles textbook how faculty advisors can deal with student apprehensiveness about taking economics courses and teaching business economics chaired by nobel laureate ronald coase as recently as the 1996 assa meetings in san francisco there were only six sessions on teaching economics and at the 1994 meetings in boston there were only four such sessions similarly small numbers of sessions were scheduled through the 1980 s here we ask whether any increased emphasis on teaching in economics departments has led to changes in how economics is taught do academic economists report that they are now becker department of economics indiana university bloomington in 47405 e mail beckerw indiana edu and adjunct professor school of international business university of south australia watts department of economics purdue university west lafayette in 47905 e mail bfp mgmt purdue edu we thank julia k huffer kevin m green siddhartha kapoor chatchai meteveravong alexandre skiba and suzanne becker for help in the mailing data entry and tabulation and preparing of this paper financial support from the purdue university center for international business education and research university of south australia school of international business and the national council on economic education through its sponsorship of the journal of economic education is gratefully acknowledged

the effects of adaptation measures on hurricane induced property losses which fema investments have the highest returns abstract this paper evaluates the relative effectiveness of fema expenditures on hurricane induced property losses we find that spending on fema ex ante mitigation and planning projects leads to greater reductions in property losses than spending on ex post adaptation programs specifically a one percent increase in annual spending on ex ante risk reduction and warning projects reduces damages by 0 21 percent while a one percent increase in ex post recovery and clean up spending reduces damages by 0 12 although both types of program spending are effective we find the marginal return from spending on programs that target long term mitigation and risk management to be almost twice that of spending on ex post recovery programs with the predicted increases in the frequency and severity of north atlantic hurricanes in the future our findings suggest there are important potential gains that could be realized from the further diversification of fema spending across project categories

varieties of clientelism machine politics during elections although many studies of clientelism focus exclusively on vote buying political machines often employ diverse portfolios of strategies we provide a theoretical framework and formal model to explain how and why machines mix four clientelist strategies during elections vote buying turnout buying abstention buying and double persuasion machines tailor their portfolios to the political preferences and voting costs of the electorate they also adapt their mix to at least five contextual factors compulsory voting ballot secrecy political salience machine support and political polarization our analysis yields numerous insights such as why the introduction of compulsory voting may increase vote buying and why enhanced ballot secrecy may increase turnout buying and abstention buying evidence from various countries is consistent with our predictions and suggests the need for empirical studies to pay closer attention to the ways in which machines combine clientelist strategies

electoral goals and center state transfers a theoretical model and empirical evidence from india we construct a model of redistributive politics where the central government is opportunistic and uses its discretion to make transfers to state governments on the basis of political considerations these considerations are the alignment between the incumbent parties at the central and state levels and whether a state is a swing state or not a testable prediction from the model is that a state that is both swing and aligned with the central government is especially likely to receive higher transfers we test this prediction using indian data for 14 states from 1974 75 to 1996 97 we find that a state which is both aligned and swing in the last state election is estimated to receive 16 higher transfers than a state which is unaligned and non swing

distributive politics and electoral competition abstract within the framework of pure redistribution dividing one unit of a homo geneous good among identical individuals the paper analyses the redistribution that arises from downsian two party electoral competition it appears that the strategic behavior of vote maximizing parties leads them to propose divisions which are not far from the egalitarian one journal of economic literature classification numbers c72 d63 d72

agent based modeling in electrical energy markets using dynamic bayesian networks due to uncertainties in generation and load optimal decision making in electrical energy markets is a complicated and challenging task participating agents in the market have to estimate optimal bidding strategies based on incomplete public information and private assessment of the future state of the market to maximize their expected profit at different time scales in this paper we present an agent based model to address the problem of short term strategic bidding of conventional generation companies gencos in a power pool based on the proposed model each genco agent develops a private probabilistic model of the market using dynamic bayesian networks employs an online learning algorithm to train the model sparse bayesian learning and infers the future state of the market to estimate the optimal bidding function we show that by using this multiagent framework the agents will be able to predict and adapt to approximate nash equilibrium of the market through time using local reasoning and incomplete publicly available data the model is implemented in matlab and is tested on four test case systems two generic systems with 5 and 15 genco agents and two ieee benchmarks 9 bus and 30 bus systems both the day ahead da and hour ahead ha bidding schemes are implemented the results show a drop in market power in the 15 agent system compared to 5 agent system along with a pareto superior equilibrium in the ha scheme compared to the da scheme which corroborates the validity of the proposed decision making model also the simulations show that introduction of an ha decision making stage as an uncertainty containment tool leads to a more stable and less volatile price signal in the market which consequently results in flatter and improved profit curves for the gencos

capital taxation under political constraints this paper studies optimal dynamic tax policy under the threat of political reform a policy will be reformed ex post if a large enough coalition of citizens supports reform thus sustainable policies are those that will continue to attract enough political support in the future we find that optimal marginal capital taxes are either progressive or u shaped so that savings are subsidized for the poor and or the middle class but are taxed for the rich u shaped capital taxes always emerge when individuals political behavior is purely determined by economic motives

partisan alignment effects on total factor productivity aray h partisan alignment effects on total factor productivity regional studies unlike the literature on political effects on real economy that suggests that partisan effects accrue through aggregate demand it is hypothesized that such effects could also accrue through aggregate supply using panel data for the spanish regions over the 1986 2010 period the main results are 1 partisan alignment effects only arise when central government enjoys a majority 2 there exist a positive contemporaneous effect and negative lagged effects and 3 in absolute value such effects vanish over time results are robust to different specifications and measures of total factor productivity tfp and methods of estimation

aging population and education finance abstract conventional wisdom suggests that aging of population will increase political pressure to tilt the composition of social spending in favor of the elderly while potentially sacrificing other publicly provided goods such as education this view seems to be supported by recent empirical findings that per child public education spending tends to be lower in us jurisdictions with higher fraction of elderly residents do these cross sectional findings also carry the dynamic implication that longevity will lead over time to waning political support for funding of public education this paper challenges such implication we present a model that is consistent with the aforementioned cross sectional regressions yet predicts an overall positive impact of increasing longevity on public education funding and economic growth

clientelism and voting behavior evidence from a field experiment in benin the author conducted a field experiment in benin to investigate the impact of clientelism on voting behavior in collaboration with four political parties involved in the 2001 presidential elections clientelist and broad public policy platforms were designed and run in twenty randomly selected villages of an average of 756 registered voters using the survey data collected after the elections the author estimated the effect of each type of message by comparing voting behavior in the villages exposed to clientelism or public policy messages treatment groups with voting behavior in the other villages control groups the author found that clientelist messages have positive and significant effect in all regions and for all types of candidates the author also found that public policy messages have a positive and significant effect in the south but a negative and significant effect in the north in addition public policy messages seem to hurt incumbents as well as regional candidates finally the evidence indicates that female voters tend to have stronger preference for public policy platforms than male voters

policy divergence and voter polarization in a structural model of elections abstractone of the most widely discussed phenomena in american politics today is the perceived increasing partisan divide that splits the u s electorate a contested question is whether this diagnosis is actually true and if so what the underlying cause might be we propose a new method that simultaneously estimates voters preferences and parties positions on economic and cultural issues we apply the model to u s presidential elections between 1972 and 2008 the model recovers candidates positions from voters behavior and decomposes changes in the overall political polarization of the electorate into changes in the distribution of voters ideal positions voter radicalization and consequences of elite polarization sorting

estrutura politica como determinante dos gastos federais this paper analyses federal expending distribution between brazilian states the hypothesis is that there are variables other than social and geographic ones that explain federal expending decisions country s political structure is also important to determine these choices positive theories of budget allocation such as congressional partisan and electoral are used to ascertain the role performed by political arrangements on the allocation of federal budget a set of political and electoral variables was used to test the importance of these theories the test of the hypothesis utilized a panel data of 27 brazilian states from 1999 to 2003 and the dependent variables used were states voluntary federal transferences and federal investment on states the results confirm the hypothesis indicating that representatives party alignment and voter s behavior on past elections influence resources distribution among states

presidential address institutions and culture how and why does distant political and economic history shape the functioning of current institutions this paper argues that individual values and convictions about the scope of application of norms of good conduct provide the missing link evidence from a variety of sources points to two main findings first individual values consistent with generalized as opposed to limited morality are widespread in societies that were ruled by non despotic political institutions in the distant past second well functioning institutions are often observed in countries or regions where individual values are consistent with generalized morality and under different identifying assumptions this suggests a causal effect from values to institutional outcomes the paper ends with a discussion of the implications for future research jel a10 d7 e00

political competition and mirrleesian income taxation a first pass we study downsian competition in a mirrleesian model of income taxation the competing politicians may dier in competence if politicians engage in vote share maximization the less competent politician s policy proposals are attractive to the minority of rich agents whereas those of the competent politician are attractive to the majority of poor agents the less competent politician wins with positive probability which gives rise to a political failure in the sense of besley and coate 1998 political failures are avoided if politicians maximize winning probabilities nevertheless the two equilibria cannot be pareto ranked the minority may be better o under vote share maximization

distributive politics and spatial equity the allocation of public investment in chile abstractdistributive politics and spatial equity the allocation of public investment in chile regional studies this paper analyzes the influence of electoral concerns on investment distribution from the central government to chilean municipalities drawing upon panel data it shows that investment is mediated by pork barrel and political budget cycles as well as favouring the relatively better off areas estimations also reveal that resources are channelled to the municipalities where the vote margin in local elections is larger whereas national results are not relevant indicating that local governments lobbying capacity is prioritized over national electoral interests based on these results the implications for regional governance and for reducing the margin of arbitrary allocations are discussed

an empirical study of applied game theory transmission constrained cournot behavior restructured energy markets present opportunities for the exercise of market power meaning market players can potentially maintain prices in excess of competitive prices in this paper we investigate cournot equilibrium in a simple example network we analyze three market players in a transmission constrained system and consider nonconstant marginal cost several scenarios are evaluated that show a pure strategy equilibrium can break down even when a transmission constraint exceeds the value of the unconstrained cournot equilibrium line flow

clientelism and vote buying lessons from field experiments in african elections electoral clientelism and vote buying are widely perceived as major obstacles to economic development this is because they may limit the provision of public goods in this paper we review the literature on clientelism and vote buying and propose the use of field experiments to evaluate empirically the consequences of these phenomena we provide an overview discuss implementation and interpret the main results of recent field experiments conducted by the authors in west african countries clientelism and vote buying seem to be effective and to enjoy widespread electoral support the results suggest that increased access to information and political participation by women may limit clientelism in addition voter education campaigns may undermine the effects of vote buying on voting behaviour we argue that our findings may inform the design of development aid interventions as a way effectively to increase public good political accountability we also discuss directions for fruitful future research copyright 2009 oxford university press

public education and pensions in democracy a political economy theory a dynamic political economy theory of scal policy is presented to explain the simultaneous existence of public education and pensions in modern democracies the driving force of the model is the intergenerational conict over the allocation of the public budget successive generations of voters choose scal policies through repeated elections the political power of elderly voters creates the motive for adults to support public investment in the human capital of future generations since it expands future pension possibilities we characterize the markov perfect equilibrium of the voting game in a small open economy the equilibrium reproduces salient features of intergenerational
