The Downsian voter meets the ecological fallacy

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

Voter turnout: How much can we explain?

This paper evaluates the ability of common explanatory variables to predict who votes. Logit voting regressions are estimated with more than three dozen explanatory variables using survey and aggregate data for the 1979, 1980, 1984, and 1988 Canadian national elections. We find that the usual demographic variables such as age and education, and contextual variables such as campaign spending have significant effects on the probability of voting, but the models have low R2's and cannot predict who votes more accurately than random guessing. We also estimate regressions using past voting behavior as a predictor of current behavior, and find that although the explanatory power rises it remains low. This suggests that the difficulty in explaining turnout arises primarily from omitted time- varying variables. In some sense, then, it appears that whether or not a person votes is to a large degree random. The evidence provides support for the rational voter theory, and is problematic for psycho/sociological approaches.     

Election closeness and voter turnout: Evidence from California ballot propositions

This paper uses a new data set of 885 California ballot propositions from 1912 through 1990 to test the hypothesis that voter turnout increases as an election becomes closer. Various measures of voter participation are regressed on various measures of election closeness. The main finding is that there is not a systematic relation between closeness and turnout. Two conclusions are drawn: (1) voters are not sensitive to the probability their votes are decisive, and (2) other studies which found higher turnout for close elections probably detected an increased mobilization of party elites in tight races.     

Public choice principles of redistricting

This paper uses fundamental principles of public choice, mainly the median voter theorem, to develop a simple theory of redistricting. The focus is on how closely policy outcomes correspond to majority rule. The main results are: (1) Potential policy bias in favor of nonmajority groups is structurally linked to the number of legislative seats and the population, and the structure of most states puts them very close to the theoretically maximum bias. (2) Random districting, which might seem like the essence of neutrality, does not eliminate policy bias on average. (3) Traditional principles of compact, contiguous districts that respect existing political boundaries, stressed in the Supreme Court’s Shaw v. Reno decision, minimize the chance of nonmajoritarian outcomes. Our analysis also offers a gerrymandering explanation for the positive relation between seats and spending that is usually taken as support for the “Law of 1/n.”     

The eclipse of legislatures: Direct democracy in the 21st century

Demographic, political, and technological trends are fueling an unprecedented growth in direct democracy worldwide. If the trends continue, direct democracy threatens to eclipse legislatures in setting the policy agenda. This article reviews existing scientific knowledge about the initiative and referendum – the main institutions of direct democracy – and highlights key issues for the future.     

Structural constraints on partisan bias under the efficient gerrymander

Partisan bias occurs when the translation of the popular vote into legislative seats differs between competing parties. This paper contains a theoretical and empirical analysis of the consequences of an efficient gerrymander for the partisan bias of an electoral system. Under partisan apportionment, bias is shown to depend on some structural features of the electoral environment; namely, the size of the voting population and the number of single-member districts within a political jurisdiction. A statistical analysis reveals the predicted relationships in data on Congressional elections across states in the 1950–1984 period. This paper highlights the importance of some measurable features of the electoral environment for determining bias and provides an indirect test of partisan gerrymandering in congressional apportionment processes.     

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.
