CANDIDATE VALENCE: EVIDENCE FROM CONSECUTIVE PRESIDENTIAL ELECTIONS*

This article develops and estimates a dynamic spatial model of voting. The distribution of voters' policy positions and candidates' valence are recovered using individual‐level data on voting decisions in two consecutive presidential elections. The estimated model is used to provide an equilibrium interpretation of observed individual voting profiles and aggregate electoral outcomes as well as to conduct counterfactual experiments that assess the impact of candidates' policy positions, valence, and voters' information on electoral outcomes.     

Indecision Theory: Weight of Evidence and Voting Behavior

In this paper, we show how to incorporate weight of evidence, or ambiguity, into a model of voting behavior. We do so in the context of the turnout decision of instrumentally rational voters who differ in their perception of the ambiguity of the candidates' policy positions. Ambiguity is reflected by the fact that the voter's beliefs are given by a set of probabilities, each of which represents in the voter's mind a different possible scenario. We show that a voter who is averse to ambiguity considers abstention strictly optimal when the candidates' policy positions are both ambiguous and they are “ambiguity complements.” Abstaining is preferred since it is tantamount to mixing the prospects embodied by the two candidates, thus enabling the voter to “hedge” the candidates' ambiguity.     

Policy Positions, Information Acquisition and Turnout

This paper explores the relationship between policy positions, information acquisition and turnout. In particular, information acquisition and turnout choices are characterized as a function of citizens' policy positions. It is found that middle‐of‐the‐road citizens are the most likely to both acquire political information and abstain. Comparative‐statics analysis of the information technology indicates that an increase in the effectiveness of information has a higher (positive) impact on information and turnout than a comparable decrease in the cost of information. Furthermore, following a polarization, information and abstention are found to increase.     

The causal effect of compulsory voting laws on turnout: Does skill matter?

A very important, yet unsettled, question is whether mandatory voting affects political participation. This paper exploits a natural experiment to assess the causal impact of compulsory voting on turnout and, more importantly, to test whether the impact is different across skill groups. I find that compulsory voting increases voter turnout by 18 percentage points (28%) and the increase is twice as much in the unskilled citizens than that in the skilled citizens. This study is the first to show, with rigorous empirical evidence, that compulsory voting laws are effective in reducing the skill/socioeconomic gap in political participation. Furthermore, by shaping the electorate, these laws have relevant consequences in terms of the economic policies applied.     

Political alienation and voter mobilization in elections

The paper examines candidates' choice between policies that increase the number of supporters and policies that foster their participation. Voter turnout is decided at the group level, in response to candidates' policies. A convex utility function captures the alienation of citizens who are far from all candidates. In equilibrium, extreme policies are adopted as a mobilization strategy, if citizens are sufficiently polarized and inclined to alienation. Otherwise, a standard result of convergence to the center obtains, in line with the persuasion of the swing voters.     

Elections,Information, and State‐Dependent Candidate Quality

The quality of political candidates often depends on the current state of the world, for example because their personal characteristics are more valuable in some situations than in others. We explore the implications of state‐dependent candidate quality in a model of electoral competition where voters are uncertain about the state. Candidates are fully informed and completely office‐motivated. With a reasonable restriction on voters' beliefs, an equilibrium where candidates' positions reveal the true state does not exist. Nonrevealing equilibria always exist. Some main findings are that candidates' positions can diverge more in equilibrium when they differ more in state‐dependent quality and when the electorate is less well informed.     

A Psychologically Based Model of Voter Turnout

We analyze a psychologically based model of voter turnout. Potential voters experience regret if they fail to vote, which is the motivation for participation in voting. Regret from abstention is inversely related to the margin of victory. Voters on the winner's side experience less regret than those on the loser's side. We show that the unique equilibrium involves positive voter turnout. We show that the losing side has higher turnout. In addition, voter turnout is positively related to importance of the election and the competitiveness of the election. We also consider scenarios in which voters are uncertain about the composition of the electorate's political preferences and show similar phenomena emerge.     

Turnout in concurrent elections: Evidence from two quasi-experiments in Italy

We study the effects of different types of concurrent elections using individual-level administrative and survey data from Italy. Exploiting different voting ages for the two Houses of Parliament in a voter-level Regression Discontinuity Design, we find no effect of Senate voting eligibility on voter turnout or information acquisition. We also estimate city-level Differences-in-Differences showing that concurrent high-salience municipal elections increase turnout in lower-salience provincial and European elections, but not vice-versa. These concurrency effects are concentrated in municipalities in the South of Italy, possibly due to weaker political parties and lower levels of social capital.     

Emigrants’ missing votes

What are the causal effects of emigration on election outcomes in the country of origin? Large emigration of high-skilled emigrants can lead to changes in the distribution of political preferences, which affect voting outcomes. Using administrative migration and voting data, we show that emigration from Poland following its accession to the European Union in 2004 caused an increase in vote shares for right-wing parties, while decreasing the vote share for left-wing parties due to emigrants’ missing left-leaning votes. To account for endogenous migration patterns, we construct an innovative instrument that measures the distance to the closest open EU border. Our results highlight that emigration enhances stayers’ trust in right-wing governments and increases stayers’ voting for parties with pro-European positions. Exploiting a change in voting rules over time allows to disentangle different mechanisms. These results have important implications for the design of voting policies.     

The effect of randomized school admissions on voter participation

There is little causal evidence on the effect of economic and policy outcomes on voting behavior. This paper uses randomized outcomes from a school choice lottery to examine if lottery outcomes affect voting behavior in a school board election. We show that losing the lottery has no significant impact on overall voting behavior; however, among white families, those with above median income and prior voting history, lottery losers were significantly more likely to vote than lottery winners. Using propensity score methods, we compare the voting of lottery participants to similar families who did not participate in the lottery. We find that losing the school choice lottery caused an increase in voter turnout among whites, while winning the lottery had no effect relative to non-participants. Overall, our empirical results lend support to models of expressive and retrospective voting, where likely voters are motivated to vote by past negative policy outcomes.     

Approval voting with endogenous candidates

We present a formal model of political competition under approval voting which allows for endogenous candidate entry. Our analysis yields a number of novel insights. First, we develop a notion of sincere voting behavior under approval voting, called relative sincerity. We then show that the relatively sincere voting behavior is consistent with the strategic calculus of voting. Second, we show that in a one-dimensional model with distance preferences, equilibria in relatively sincere strategies and without spoiler candidates always generate outcomes close to the median voter. Moreover, approval voting satisfies Duverger's Law in the sense that there are at most two winning positions! Finally, we extend our analysis to arbitrary policy spaces. In the general setting, approval voting is shown to be susceptible to the same kinds of problems as the plurality rule, such as the possibility of non-majoritarian outcomes, failure to elect the Condorcet winner and existence of spoiler candidates.     

Voting as a signaling device

In this paper, citizens vote in order to influence the election outcome and in order to signal their unobserved characteristics to others. The model is one of rational voting and generates the following predictions: (i) The paradox of not voting does not arise, because the benefit of voting does not vanish with population size. (ii) Turnout in elections is positively related to the importance of social interactions. (iii) Voting may exhibit bandwagon effects and small changes in the electoral incentives may generate large changes in turnout due to signaling effects. (iv) Signaling incentives increase the sensitivity of turnout to voting incentives in communities with low opportunity cost of social interaction, while the opposite is true for communities with high cost of social interaction. Therefore, the model predicts less volatile turnout for the latter type of communities.     

Vox Populi,Vox Dei? Tacit collusion in politics

We study competition between political parties in repeated elections with probabilistic voting. This model entails multiple equilibria, and we focus on cases where political collusion occurs. When parties hold different opinions on some policy, they may take different policy positions that do not coincide with the median voter's preferred policy platform. In contrast, when parties have a mutual understanding on a particular policy, their policy positions may converge (on some dimension) but not to the median voter's preferred policy. That is to say, parties can tacitly collude with one another, despite political competition. Collusion may collapse, for instance, after the entry of a new political party. This model rationalizes patterns in survey data from Sweden, where politicians on different sides of the political spectrum take different positions on economic policy but similar positions on refugee intake—diverging from the average voter's position, but only until the entry of a populist party.     

Patronage and ideology in electoral behavior: Evidence from Egypt's first presidential elections

This paper investigates the impact of patronage and ideology on voter behavior and election outcomes. Egypt's first free presidential elections represent a good case study to answer the question whether private gain outweighs ideology in voter behavior on a broader level. First, we combine election results with household surveys and national statistics to estimate the impact of patronage (measured by public employment) on voting for the pre-revolution regime candidate. Second, using results of the first round of elections as a proxy for ideology, we test for the effect of ideological preferences on voting behavior. Additionally, we test for candidates' ability to mobilize supporters. Our results suggest that patronage has a stronger effect than secularist ideology but a weaker effect than pro-change ideology. Results show that the number of public sector and government employees in each electoral district has a positive impact on participation rates.     

Learning in Elections and Voter Turnout

Voter turnout in game theoretic models of voting has typically been difficult to predict because of the problem of multiple Nash equilibria ( Palfrey and Rosenthal 1983, 1985 ). Many of these equilibria require an extreme precision of beliefs among voters that is unlikely to be reached in real elections. At the same time, mechanisms like pre‐election polls exist to shape the beliefs of voters about expected turnout. We combine these two features in a model of voter learning in elections and characterize the asymptotically stable equilibria of both complete and incomplete information games in a simple symmetric setting with two candidates. We also show how the model can be used to qualitatively explain several phenomena observed in reality: increases in costs of voting affect turnout adversely but there may be persistence of turnout levels between elections even though costs and other parameters change. Increase in uncertainty increases turnout while increases in the size of the electorate decrease it, in line with intuition.     

IMPERFECTLY INFORMED VOTERS AND STRATEGIC EXTREMISM

We analyze a two‐candidate Downsian model considering that voters use shortcuts (e.g., interest‐group/media endorsements) to infer candidates' policy platforms. That is, voters do not observe candidates' exact platforms but only which candidate offers the more leftist/rightist platform (relative positions). In equilibrium, candidates' behavior tends to maximum extremism, but it may converge or diverge depending on how voters behave when indifferent policywise between the candidates. When the tie‐breaking rule used by the voters is sufficiently fair, candidates converge to the extreme preferred by the median voter, but when it strongly favors a certain candidate, each candidate specializes in a different extreme.     

Income Taxation and the Diversity of Consumer Goods: A Political Economy Approach*

After‐tax income inequality has risen since the mid‐1990s, as increases in market income inequality have not been offset by greater fiscal redistribution. We argue that the substantial increase in the diversity of consumer goods has mitigated mounting political pressures for redistribution. Within a probabilistic voting framework, we demonstrate that if the share of diversified goods in the consumption bundle increases sufficiently with income, then an increase in goods diversity can reduce the political equilibrium tax rate. Focusing on OECD countries, we find empirical support for both the model's micro‐political foundations and the implied relation between goods diversity and fiscal policy outcomes.     

Too afraid to vote? The effects of COVID-19 on voting behaviour

This paper studies the causal effect of local exposure to COVID-19 on voting behaviour and electoral outcomes using evidence from the regional elections held in Spain on 12 July 2020. Exploiting the variation in exposure to COVID-19 and using a difference-in-differences identification strategy, we show that turnout was between 2.6 and 5.1 percentage points lower in municipalities that experienced positive cases of COVID-19. In addition, the results show a substantial increase in the probability of voting for nationalist parties. We discuss the idea of perceived fear being the potential mechanism driving our results.     

Voter turnout and government's legitimate mandate

The paper studies a group-mobilization model of costly voting in which citizens care about the legitimate mandate of the government formed by the winning group. This, as a function of the electorate's voting behavior, depends on both the margin of victory and the total turnout rate. Citizens prefer a high mandate when their own group forms the government but a low one if the government is formed by an opposing group. As such, the eventual losing group faces a trade-off: a higher participation from its members decreases the margin of victory but increases the total turnout. In equilibrium, a second fundamental trade-off arises, which overturns the supposed positive relationship between turnout and mandate: as the total turnout becomes more important for the government's mandate, the first decreases but the second strengthens. The key mechanism at play is a shift in the relative participation of the two groups, which favors the majority and raises its margin of victory, thus yielding a bandwagon effect. The implications for the evolution of turnout and the occurrence of election boycotts are discussed.     

Dissertation abstract: Voting in the laboratory

Almost every week national elections are held somewhere in the world. Many more elections take place at federal and local levels of government. Surely, these are important events to many of us. This thesis aims at providing a better understanding of why and how people vote in elections. Three original modifications of Palfrey and Rosenthal’s (1983) participation game are used to study voter turnout theoretically and experimentally.¹ In the basic game, each voter supports (i.e., prefers) one of two exogenous candidates and privately decides between voting at a cost and abstaining (without costs). The candidate who receives more votes wins the election (ties are broken randomly) and each supporter of this candidate receives an equal reward, independent of whether or not she voted. The first study (published in the American Political Science Review 100, pp. 235–248) analyzes the effects of social embeddedness on turnout, assuming that voters may be influenced by observing the decisions of other voters around them (e.g., a family or working place). Our experimental results show that the social context matters: this information increases turnout by more than 50%. The increase is greater when neighbors support the same candidate rather than when they support opponents. The second study investigates the effects of public opinion polls on voter turnout and welfare. Poll releases resolve uncertainty about the level of support for each candidate caused by `floating’ voters, whose preferences change across elections. This information increases turnout in the laboratory by 28–34%, depending on the fraction of floating voters in the electorate. If polls indicate equal levels of support for both candidates—in which case aggregate benefits for society are not affected by the outcome—welfare decreases substantially due to costs from excessive turnout. In the final study, elections are preceded by the competition between two candidates: they simultaneously announce binding policy offers in which some voters can be favored at the expense of others through inclusion and exclusion in budget expenditure (Myerson 1993).² We observe that policy offers include 33% more voters—yielding a smaller budget share for each—when voting is compulsory rather than voluntary. Moreover, we find evidence of political bonds between voters and long-lived parties. Overall, in all three experiments many subjects strongly react to economic incentives (i.e., benefits, costs, and informational clues), often in line with what is observed outside of the laboratory.
