on the robustness of robustness checks of the environmental kuznets curve hypothesis since its first inception in the debate on the relationship between environment and growth in 1992 the environmental kuznets curve hypothesis ekc hereafter has been subject of continuous and intense scrutiny the most recent line of investigation criticizes the ekc hypothesis on more fundamental grounds in that it stresses the lack of sufficient statistical testing of the empirical relationship and questions the very existence of the notion of ekc attention is in particular drawn on the stationarity properties of the series involved per capita emissions or concentrations and per capita gdp and in case of presence of unit roots on the cointegration property that must be present for the ekc to be a well defined concept only at that point can the researcher ask whether the long run relationship exhibits an inverted u pattern on the basis of panel integration and cointegration tests for sulfur stern 2004 and perman and stern 1999 2003 have presented evidence and forcefully stated that the ekc hypothesis does not exist in this paper we ask whether similar strong conclusions can be arrived at when carrying out tests of system fractional integration and cointegration as an example we use the controversial case of carbon dioxide emissions the results show that more ekcs come back into life relative to traditional integration cointegration tests however we confirm that the ekc hypothesis remains a fragile concept

media competition and electoral politics we build a framework linking competition in the media market to political participation media outlets report on the ability of candidates running for office and compete for audience through their choice of slant citizens consume news only if the expected utility of being informed about candidates ability is sufficiently large for their group collectively our results can reconcile seemingly contradictory empirical evidence showing that entry in the media market can either increase or decrease turnout while information pushes up independent turnout partisans adjust their turnout to the ability of their preferred candidate and on average they vote less when informed

the toxic intensity of industrial production global patterns trends and trade policy this paper exploits a newly developed data set to investigate recent changes in the international distribution of industrial pollution in particular the authors examine three issues 1 the relationship between the toxic intensity of industrial production and the level of economic development 2 the impact of oecd environmental regulation on global changes in toxic intensity and 3 the relationship between trade policy and the toxic intensity of industrial production in ldc s 10 refs

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

environmental kuznets curves real progress or passing the buck abstract recent research has examined the hypothesis of an environmental kuznets curve ekc the notion that environmental impact increases in the early stages of development followed by declines in the later stages these studies have focused on the relationship between per capita income and a variety of environmental indicators results imply that ekcs may exist for a number of cases however the measures of environmental impact used generally focus on production processes and reflect environmental impacts that are local in nature and for which abatement is relatively inexpensive in terms of monetary costs and or lifestyle changes significantly more consumption based measures such co2 emissions and municipal waste for which impacts are relatively easy to externalize or costly to control show no tendency to decline with increasing per capita income by considering consumption and trade patterns the author re examines the concept of the ekc and proposes the use of alternative consumption based measures of environmental impact the author speculates that what appear to be improvements in environmental quality may in reality be indicators of increased ability of consumers in wealthy nations to distance themselves from the environmental degradation associated with their consumption

mass media instrumental information and electoral accountability journalism is widely believed to be crucial for holding elected officials accountable at the same time economic theory has a hard time providing an instrumental explanation for the existence of accountability journalism according to the common downsian reasoning rational voters should not be willing to pay for information out of purely instrumental motives because the individual probabilities of casting the decisive vote are typically very low we show that this rationale does not apply when a group of voters shares a common goal such as accountability and information is delivered via mass media in contrast to the pessimistic downsian view rational voters can have a considerable willingness to pay for the provision of instrumental information in these scenarios our model thus reconciles the rational voter approach with the common perception of journalism as a watchdog that holds elected officials accountable

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

optimal voting schemes with costly information acquisition a group of individuals with identical preferences must make a decision under uncertainty about which decision is best before the decision is made each agent can privately acquire a costly and imperfect signal we discuss how to design a mechanism for eliciting and aggregating the collected information so as to maximize ex ante social welfare we first show that of all mechanisms a sequential one is optimal and works as follows at random one agent at a time is selected to acquire information and report the resulting signal agents are informed of neither their position in the sequence nor of other reports acquiring information when called upon and reporting truthfully is an equilibrium we next characterize the ex ante optimal scheme among all ex post efficient mechanisms in this mechanism a decision is made when the precision of the posterior exceeds a cut off that decreases with each additional report the restriction to ex post efficiency is shown to be without loss when the available signals are sufficiently imprecise on the other hand ex post efficient mechanisms are shown to be suboptimal when the cost of information acquisition is sufficiently small

information aggregation rationality and the condorcet jury theorem the condorcet jury theorem states that majorities are more likely than any single individual to select the better of two alternatives when there exists uncertainty about which of the two alternatives is in fact preferred most extant proofs of this theorem implicitly make the behavioral assumption that individuals vote sincerely in the collective decision making a seemingly innocuous assumption given that individuals are taken to possess a common preference for selecting the better alternative however in the model analyzed here we find that sincere behavior by all individuals is not rational even when individuals have such a common preference in particular sincere voting does not constitute a nash equilibrium a satisfactory rational choice foundation for the claim that majorities invariably do better than individuals therefore has yet to be derived

aggregation and social choice a mean voter theorem a celebrated result of black 1948a demonstrates the existence of a simple majority winner when preferences are single peaked the social choice follows the preferences of the median voter the median voter s most preferred outcome beats any alternative however this conclusion does not extend to elections in which candidates differ in more than one dimension this paper provides a multi dimensional analog of the median voter result we provide conditions under which the mean voter s most preferred outcome is unbeatable according to a 64 majority rule the conditions supporting this result represent a significant generalization of caplin and nalebuff 1988 the proof of our mean voter result uses a mathematical aggregation theorem due to prekopa 1971 1973 and borell 1975 this theorem has broad applications in economics an application to the distribution of income is described at the end of this paper results on imperfect competition are presented in the companion paper caplin and nalebuff 1991

turnout political preferences and information experimental evidence from peru abstract i combine a field experiment with a change in voting laws reducing the fine for abstention to assess the effects of monetary incentives to encourage voter participation in a real world election using experimental variation in the perceived reduction of the fine for abstention i estimate that receiving information about a reduction in the fine by 50 75 percent causes a decrease in turnout of 2 6 5 3 percentage points these estimates imply a cost elasticity of voting of 0 22 the reduction in turnout is driven by voters who are in the center of the political spectrum hold less political information and have lower subjective value of voting the increase in abstention does not change aggregate preferences for specific policies further involvement in politics as measured by the decision to acquire political information is independent of the level of the fine additional results indicate that the reduction in the fine reduces the incidence of vote buying and increases the price paid for a vote

voluntary voting costs and benefits we compare voluntary and compulsory voting in a condorcet type model in which voters have identical preferences but dierential information with voluntary voting all equilibria involve sincere voting and positive participation thus in contrast to situations with compulsory voting there is no con ict be tween strategic and sincere behavior when voting is costless voluntary voting is welfare superior to compulsory voting even when voting is costly participa tion rates are such that in the limit the correct candidate is elected that is information fully aggregates

does education improve citizenship evidence from the united states and the united kingdom abstract many studies document an association between schooling and civic participation but none credibly investigate causal links we explore the effect of extra schooling induced through compulsory schooling laws on the likelihood of becoming politically involved in the united states and the united kingdom we find that educational attainment is related to several measures of political interest and involvement in both countries we find a strong and robust relationship between education and voting for the united states but not for the united kingdom our us results approach the uk findings when conditioning on registration possibly indicating that registration rules present a barrier to participation

voting with endogenous information acquisition experimental evidence abstract the condorcet jury model with costless but informative signals about the true state of the world predicts that the efficiency of group decision making increases unambiguously with the group size however if signal acquisition is made an endogenous and costly decision then rational voters have disincentives to purchase information as the group size becomes larger we investigate the extent to which human subjects recognize this trade off between better information aggregation and greater incentives to free ride in a laboratory experiment where we vary the group size the cost of information acquisition and the precision of signals we find that the theory predicts well in the case of precise signals however when signals are imprecise free riding incentives appear to be much weaker as there is a pronounced tendency for subjects to over acquire information relative to equilibrium predictions we rationalize the latter finding using a quantal response equilibrium that allows for risk aversion

the paradox of information and voter turnout the most prominent explanation for the paradox of voter turnout is that citizens are willing to bear the cost of voting because they perceive a benefit e g fulfilling a civic duty or expressing themselves that is independent of the election outcome however a separate literature highlights the empirical importance of information for voter participation and existing explanations for this are that uninformed citizens either expect smaller benefits from voting or defer strategically to peers who know more this paper simply points out that while either of these theories offers a plausible explanation for the importance of information neither is robust if the motivation for voting is unrelated to the election outcome this is because citizens with positive net voting costs should abstain no matter how well informed while those with negative net voting costs should vote no matter how poorly informed thus the purported resolution to the turnout paradox raises a new paradox of information and voter turnout intuitively the quality of a vote should matter only if the vote is somehow instrumental suggesting that future work should continue to explore instrumental rationales for voting

explaining voter turnout patterns an information theory voting research is rich in empirical regularities yet a parsimonious theory of voter turnout that can match the facts has proven to be elusive this paper argues that voter turnout patterns can be explained by extending the traditional rational voter model to include limited information a model is presented in which utility maximizing consumers receive higher payoffs from voting the more confident they are of their vote choice the model provides an explanation for the most important cross sectional voter turnout patterns in addition it suggests a novel explanation for the post 1960 decline in u s participation

optimal expenditures for agricultural research and extension implications of underfunding significant increases in agricultural productivity will be needed for the united states to meet its future food policy goals related to an abundant and stable food supply the nation s ability to meet this challenge will depend on the level of investment in agricultural research and extension each dollar of underfunding relative to the economically efficient level of research and extension expenditures a will cost the government 2 56 1 50 discounted if it later makes up for the low investment level or b will cost consumers 4 39 3 07 discounted if the government does not make up for the low level of investment

the environmental kuznets curve semi parametrically revisited this paper re examines the existence of an environmental kuznets curve ekc across countries using a semi parametric regression estimator which places no restrictions on the functional form our results using cross country panel data on sulfur and carbon dioxide strongly suggest that the relationship between wealth and environmental degradation is not bell shaped as suggested by an ekc rather that there is a positive link for the very poorest countries and no clear relationship for richer countries

media and political persuasion evidence from russia this paper compares electoral outcomes of 1999 parliamentary elections in russia among geographical areas with differential access to the only national tv channel independent from the government it was available to three quarters of russia s population and its signal availability was idiosyncratic conditional on observables independent tv decreased aggregate vote for the government party by 8 9 percentage points increased the combined vote for major opposition parties by 6 3 percentage points and decreased turnout by 3 8 percentage points the probability of voting for opposition parties increased for individuals who watched independent tv even controlling for voting intentions measured one month before elections jel d72 l82 p26

a fractional cointegration analysis of purchasing power parity a generalized notion of cointegration called fractional cointegration is introduced to examine the long run purchasing power parity ppp hypothesis by allowing deviations from equilibrium to follow a fractionally integrated process the fractional cointegration analysis can capture a wider range of mean reversion behavior than standard cointegration analyses this gain is flexibility in modeling subtle mean reverting dynamics is found to be important for a proper evaluation of long run ppp empirical results based on historical data for the 1914 1989 period show that ppp reversion exists and can be characterized by a fractionally integrated process in three out of five countries studied the results support ppp as a long run phenomenon though significant short run deviations from ppp can exist

abstention in elections with asymmetric information and diverse preferences we analyze a model of a two candidate election with costless voting in which voters have asymmetric information and diverse preferences we demonstrate that a strictly positive fraction of the electorate will abstain and that nevertheless elections effectively aggregate voters private information using examples we show that more informed voters are more likely to vote than their less informed counterparts increasing the fraction of the electorate that is informed however may lead to higher levels of abstention we conclude by showing that a biased distribution of information can lead to a biased voting population but does not lead to biased outcomes

costly participation and heterogeneous preferences in informational committees informational committees are groups of people who are designated to gather information this article develops a simple model of committee size based on costly participation and preference heterogeneity in a setting in which the information structure and policy preferences are both represented by normal random variables i characterize an equilibrium under the mean decision rule and derive the optimal committee size i show that when effort costs are sufficiently high preference heterogeneity can provide members additional incentives to gather information and thus the optimal committee size and the principal s expected payoff can increase in the heterogeneity of committee members policy preferences

the swing voter s curse in the laboratory this paper reports the first laboratory study of the swing voter s curse and provides insights on the larger theoretical and empirical literature on pivotal voter models our experiment controls for different information levels of voters as well as the size of the electorate the distribution of preferences and other theoretically relevant parameters the design varies the share of partisan voters and the prior belief about a payoff relevant state of the world our results support the equilibrium predictions of the feddersen pesendorfer model and clearly reject the notion that voters in the laboratory use naive decision theoretic strategies the voters act as if they are aware of the swing voter s curse and adjust their behavior to compensate while the compensation is not complete and there is some heterogeneity in individual behavior we find that aggregate outcomes such as efficiency turnout and margin of victory closely track the theoretical predictions

committee design with endogenous information this paper is concerned with the arrangements for collective decision making in a world where agents must be motivated to acquire information the analysis identifies some basic forces shaping the design of panels of decision makers referees managers jurors etc in situations where decision makers are useful only in so far as they expend some effort to gain information about the alternatives at hand these situations are common one being the refereeing process where an editor requires the opinions of a number of experts who must read the paper acquire information in order to give an opinion as to publication analogously in committees which screen applicants to a programme the committee members must gain information about the applicant s qualifications and likelihood of success in order to evaluate whether to admit him her finally in trial juries it is important that jurors pay attention to the evidence in order to make an informed judgement 1 we focus on environments where information is a public good in the sense that the social benefits of one decision maker acquiring information exceed the private benefits a good mechanism in this environment must not only aggregate information efficiently but also induce the decision makers to acquire information we analyse the design of voting mechanisms our problem is to choose two parameters which determine both the incentive to acquire information and the efficiency with which information is aggregated the first parameter is the size of the decision making unit the number of committee members the second is the plurality required to overturn the status quo the voting rule our main result is this a voting rule that requires a large plurality in the extreme unanimity to upset the status quo can be optimal only if the information available to each committee member is sufficiently accurate when individual information is noisy the drawback

television and voter turnout i use variation across markets in the timing of television s introduction to identify its impact on voter turnout the estimated effect is significantly negative accounting for between a quarter and a half of the total decline in turnout since the 1950s i argue that substitution away from other media with more political coverage provides a plausible mechanism linking television to voting as evidence for this i show that the entry of television in a market coincided with sharp drops in consumption of newspapers and radio and in political knowledge as measured by election surveys i also show that both the information and turnout effects were largest in off year congressional elections which receive extensive coverage in newspapers but little or no coverage on television

would rational voters acquire costly information abstract we analyze an election in which voters are uncertain about which of two alternatives is better for them voters can acquire some costly information about the alternatives in agreement with downs s rational ignorance hypothesis individual investment in political information declines to zero as the number of voters increases however if the marginal cost of information is near zero for nearly irrelevant information there is a sequence of equilibria such that the election outcome is likely to correspond to the interests of the majority for arbitrarily large numbers of voters thus rationally ignorant voters are consistent with a well informed electorate

does political knowledge increase turnout evidence from the 1997 british general election a number of recent formal models predict a positive effect of political knowledge on turnout both information acquisition and turnout however are likely to be determined by a similar set of variables rendering hard the identification of a causal link in empirical investigations available empirical regularities should therefore be interpreted as mere correlations i address this problem by using an intrumental variables approach where the instruments are represented by various proxies of information supply on mass media using survey data from the 1997 british general election study i show that political knowledge has a sizeable influence on the probability of voting and that mass media play an important role in influencing political participation

demand for slant how abstention shapes voters choice of news media political commentators warn that the fragmentation of the modern media landscape induces voters to withdraw into information cocoons and segregate along ideological lines we show that the option to abstain breaks ideological segregation and generates cross over in news consumption voters with considerable leanings towards a candidate demand information that is less biased towards that candidate than voters who are more centrist this non monotonicity in the demand for slant makes voters ideologies non recoverable from their choice of news media and generates disproportionate demand for media outlets that are centrist or only moderately biased it also implies that polarisation of the electorate may lead to an ideological moderation in news consumption

signaling with costly acquisition of signals in this paper we investigate the consequences of introducing a cost to observe the signal in an otherwise standard signaling game beyond identifying equilibria which we contrast with those of a standard signaling game we study their robustness to two important classes of refinements acting through restrictions on out of equilibrium beliefs and through trembles our results suggest that more prominence should be given to the pooling outcome on the minimum signal

the curse of uninformed voting an experimental study we study majority voting over two alternatives in small groups individuals have identical preferences but are uncertain about which alternative can better achieve their common interest before voting each individual can obtain information by buying a valuable but imperfect signal about the better alternative voting is either voluntary or compulsory in the compulsory mode each individual must vote between the two alternatives while in the voluntary mode they can also abstain an uninformed random vote generates a negative externality since it may override an informative group decision in pivotal events in our experiments participants in randomly re matched groups obtain information more often with compulsory than voluntary voting and the average number of signals is greater in larger than smaller groups surprisingly uninformed voting is common even in the voluntary mode finally group performance is poor in all treatments indicating the need to reconsider current practice of jury and committee voting

a theory of conservatism a free rider problem arises when a group choice between two alternatives has to be made on the basis of privately collected evidence leading to insufficient effort in gathering evidence and an ex ante welfare loss for the group to alleviate the free rider problem the group can commit to a conservative rule whereby the decision is made against the alternative favored by the group s preference or prior when evidence supports it but is not preponderant optimal conservatism increases private incentives to gather evidence and improves the quality of the group decision my result explains why sometimes groups appear overly cautious toward favored alternatives

common value elections with private information and informative priors theory and experiments abstract we study efficiency and information aggregation in common value elections with contin uous private signals and informative priors we show that small elections are not generally efficient and that there are equilibria where some voters vote against their private signal even if it provides useful information and abstention is allowed this is not the case in large elections where the fraction of voters who vote against their private signal tends to zero in an experiment we then study how informativeness of priors and private signals impact efficiency and information aggregation in small elections we find that there is a substantial amount of voting against the private signal moreover while most experimental elections are efficient we find that it is not generally the case that better private information leads to better decisions

choosing not to choose on the link between information and abstention abstract we use a dataset that allows us to circumvent a number of estimation difficulties that have plagued previous studies of the relationship between information and abstention our results show that information is a major determinant of abstention

when collective ignorance is bliss theory and experiment on voting for learning abstract when do groups and societies choose to be uninformed we study a committee that needs to vote on a reform which will give every member a private state dependent payoff the committee can vote to learn the state at no cost we show that the committee votes not to learn the state whenever independent voters are more divided than partisans this implies that groups with conflicting preferences tend to seek less information a laboratory experiment shows that committees are substantially more likely to vote against acquiring information when the theory predicts them to do so we also observe deviations from theory that are largely explained by cognitive limitations at the same time subjects with more experience or with greater strategic competence are more likely to vote in line with the theory providing evidence for external validity of the model

rational choice theory and the paradox of not voting at least since downs s 1957 seminal work an economic theory of democracy rational choice theorists have appreciated the paradox of not voting in a large election the probability that an individual vote might change the election outcome is vanishingly small if each person only votes for the purpose of influencing the election outcome then even a small cost to vote like a minor schedule conflict or mildly bad weather should dissuade anyone from voting yet it seems that many people will put up with long lines daunting registration requirements and even the threat of physical violence or arrest in order to vote given the central place of voting within political economy the lack of an adequate rational choice model of large elections with costly voting presents an obvious problem for the most part theorists have bypassed the turnout problem either by eliminating voters as strategic actors or by assuming that the decision to vote is independent of other strategic choices the problem with the first approach is that the empirical literature on voting behavior provides considerable evidence of apparently strategic behavior in primary elections there is evidence that voters condition their vote choice on the viability of candidates abramson aldrich paolino and rohde 1992 in a seminal and comprehensive study cox 1997 shows that voting patterns and election outcomes are broadly consistent with patterns of behavior predicted by strategic voting models for example under plurality rule in which the candidate with the most votes wins the election

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

reassessing the environmental kuznets curve for co2 emissions a robustness exercise the number of studies seeking to empirically characterize the reduced form relationship between a country economic growth and the quantity of pollutants produced in the process has recently increased significantly in several cases researchers have found evidence pointing to an inverted u benvironmental kuznetsq curve in the case of co2 however the evidence is at best mixed in this paper we reconsider that evidence by assessing how robust it is when the analysis is conducted in a different parametric setup and when using alternative emissions data from the international energy agency relative to the literature our contribution can be viewed as a robustness exercise in these two respects the econometric results lead to two conclusions firstly published evidence on the ekc does not appear to depend upon the source of the data at least as far as carbon dioxide is concerned secondly when an alternative functional form is employed there is evidence of an inverted u pattern for the group of oecd countries with reasonable turning point regardless of the data set employed not so for non oecd countries as the ekc is basically increasing slowly concave according to the iea data and more bellshaped in the case of cdiac data d 2005 elsevier b v all rights reserved

pooled mean group estimation of an environmental kuznets curve for co2 abstract we apply the pooled mean group estimator to test for the existence of an environmental kuznets curve for co2 in 22 oecd countries this approach allows for more flexible assumptions in a panel data framework the period goes from 1975 to 1998

the swing voter s curse the authors analyze two candidate elections in which some voters are uncertain about the realization of a state variable that affects the utility of all voters they demonstrate the existence of a swing voter s curse less informed indifferent voters strictly prefer to abstain rather than vote for either candidate even when voting is costless the swing voter s curse leads to the equilibrium result that a substantial fraction of the electorate will abstain even though all abstainers strictly prefer voting for one candidate over voting for another copyright 1996 by american economic association

ignorance and bias in collective decisions we study theoretically and experimentally a committee with common interests committee members do not know which of two alternatives is the best but each member can acquire privately a costly signal before casting a vote under either majority or unanimity rule in the experiment as predicted by bayesian equilibrium voters are more likely to acquire information under majority rule and attempt to counter the bias in favor of one alternative under unanimity rule as opposed to bayesian equilibrium predictions however many committee members vote when uninformed moreover uninformed voting is strongly associated with a lower propensity to acquire information we show that an equilibrium model of subjective prior beliefs can account for both these phenomena and provides a good overall fit to the observed patterns of behavior both in terms of rational ignorance and biases

political rents and voter information in search equilibrium abstract political parties committed to grab rents may run for election and even win if citizens are uninformed but how is the political equilibrium affected if citizens can mitigate this information problem through costly information search we propose a political equilibrium theory with endogenous information search and turnout we show that i the political equilibrium generates political uncertainty characterized by a distribution of rent policies i i the expectation of this rent distribution is inversely u shaped in the information search cost i i i turnout is lower and rents are higher the more proportional is the electoral system

beyond ses a resource model of political participation this paper develops a resource model of political participation the resources considered are time money and civic skills those communications and organizational capacities that are essential to political activity these skills are not only acquired early in life but developed in the nonpolitical institutional settings of adult life the workplace organizations and churches and synagogues these resources are distributed differentially among groups defined by socioeconomic status a two stage least squares analysis shows these resources have powerful effects on overall political activity thus explaining why socioeconomic status has traditionally been so powerful in predicting participation we disaggregate overall activity into three kinds of acts those that involve giving time those that entail donating money and voting each requires a different configuration of resources resulting in different patterns of stratification across various political acts

structural breaks and fractional integration in the us output and unemployment rate abstract in this article we examine the presence of structural breaks in the us output and unemployment rate by means of using fractionally integrated techniques the results based on robinson s journal of the american statistical association 89 1994 1420 tests indicate that for unemployment the inclusion of breaks does not affect to the degree of integration of the series while for the gnp we observe a reduction in its order of integration of about 0 25 when a break due to the oil price crisis is taken into account

abstention ideology and information acquisition we consider an election in which each voter can collect information of different precision voters have asymmetric information and preferences that vary both in terms of ideology and intensity in contrast to all other models of voting with endogenous information in equilibrium voters collect information of different qualities we show that information and abstention are not necessarily negatively correlated some voters are more likely to abstain the more informed they are we also discuss the manner in which incentives to acquire information are non monotonic in terms of both ideology and the level of intensity

aggregating information by voting the wisdom of the experts versus the wisdom of the masses this article analyzes participation and information aggregation in a common value election with continuous private signals in equilibrium some citizens ignore their private information and abstain from voting in deference to those with higher quality signals even as the number of highly informed peers grows large however citizens with only moderate expertise continue voting so that voter participation remains at realistic levels e g 50 to 60 percent for simple examples the precise level of voter turnout along with the margin of victory are determined by the distribution of expertise improving a voter s information makes her more willing to vote consistent with a growing body of empirical evidence but makes her peers more willing to abstain providing a new explanation for various empirical patterns of voting equilibrium participation is optimal even though the marginal voter may have very little e g below average expertise and even though nonvoters information is not utilized copyright oxford university press
