| Abstract: | We study the effects of stochastic (probabilistic) voting on equilibrium locations, equilibrium vote shares and comparative statics in a setup with three heterogenous candidates and a single-dimensional issue space. Comparing the equilibria with and without stochastic voting, we find that under an appropriate level of uncertainty about voter behavior, the model has a pure strategy Nash Equilibrium (PSNE) that is free from several non-plausible features of the PSNE under deterministic voting. The results are robust to extensions to asymmetric density and plurality maximization. |

| Abstract: | The paper studies the effect of additional government revenues on political corruption and on the quality of politicians, both with theory and data. The theory is based on a version of the career concerns model of political agency with endogenous entry of political candidates. The evidence refers to municipalities in Brazil, where federal transfers to municipal governments change exogenously according to given population thresholds. We exploit a regression discontinuity design to test the implications of the theory and identify the causal effect of larger federal transfers on political corruption and the observed features of political candidates at the municipal level. In accordance with the predictions of the theory, we find that larger transfers increase political corruption and reduce the quality of candidates for mayor. |

| Abstract: | This paper tests the hypothesis that international migration experiences may promote better institutions at home by raising the demand for political accountability. In order to examine this question, we use a simple postcard voting experiment designed to capture the population’s desire for better governance. Using data from a tailored household survey, we examine the determinants of voting behavior in our experiment, and isolate the positive effect of international emigration on the demand for political accountability. We find that this effect can be mainly attributed to the presence of return migrants, particularly to those who emigrated to countries with better governance. |

| Abstract: | I study both local and global Nash equilibria of a model of three-candidate unidimensional spatial competition. In the model, candidates may have different non-policy characteristics (valence). Generalizing the base model studied in Evrenk (2009a;b) the model allows for an asymmetric voter density as well as plurality-maximizing candidates. Unlike the standard Hotelling-Downs model of multi-candidate competition, under an asymmetric density with (heterogenous) vote-maximizing candidates a pure strategy Nash equilibrium (PSNE) exists. Further, this PSNE is free from several non-plausible features of PSNE under a symmetric density. When candidates are plurality-maximizers, some of the PSNE are supported by paradoxical candidate behavior. Further, when voter density is asymmetric and candidates are plurality-maximizers, there are several non-monotonicities in the PSNE. |

| Abstract: | Using a cross-national perspective covering all free and partly free countries, this thesis addresses two questions: What factors are associated with levels of gender representation, ethnic group representation, and ideological representation? And what are the relationships between levels of gender, ethnic group, and ideological representation? Ideological representation regards policy positions in different issue domains, whilst gender and ethnic group representation are concerned with the inclusion of women and ethnic groups in parliament. The representation of ethnic groups is approached in a multivariate cross-national analysis for the first time. Cultural rather than institutional factors seem to be the best predictors for the different levels of gender representation and ethnic group representation. Cultural attitudes are measured with survey questions on attitudes to women as political leaders, and tolerance of marginalized groups in society. The thesis finds that on average quotas for women and ethnic groups are not associated with higher levels of representation, perhaps because of issues regarding how quotas are implemented. Broadly speaking, little effect of the electoral system on any form of representation could be observed. Looking at levels of ideological representation, in line with some recent studies, the thesis suggests that the electoral system is not associated with different levels of ideological representation. I show that this is the case across various policy domains. Furthermore, the thesis finds no evidence for a direct relationship between levels of gender representation and levels of ethnic group representation, but levels of gender representation may be associated with levels of left–right representation. The relationship between different forms of representation might be shaped by the salience of ideological domains and awareness of under-representation of ethnic minority groups. Overall, the thesis argues that cultural attitudes are central to understanding levels of political representation, a factor often neglected in the literature. |

| Abstract: | Explaining human cooperation in large groups of non-kin is a major challenge to both rational choice theory and the theory of evolution. Recent research suggests that group cooperation can be explained assuming that cooperators can punish non-cooperators or cheaters. The experimental evidence comes from economic games in which group members are informed about the behavior of all others and cheating occurs in full view. We demonstrate that under more realistic information conditions, where cheating is less obvious, punishment is ineffective in enforcing cooperation. Evidently, the explanatory power of punishment is constrained by the visibility of cheating. |
