This paper examines how natural disasters shape electoral preferences by analyzing the impact of earthquakes in Italy between 1990 and 2019. Using a staggered Difference-in-Differences design, we estimate that affected municipalities are more likely to elect female, more educated, and older city...

In the 2024 European Parliament elections turnout varied significantly across EU Member States, influenced by institutional factors such as compulsory voting and concurrent elections. Socioeconomic disparities persisted; older, higher-educated, and wealthier citizens were more likely to vote,...

What are the consequences of losing political representation in a democracy? A reform of Germany’s mixed electoral system left more than 7 million citizens in 23 constituencies without a directly elected representative after the 2025 national election. Which and how many constituencies were...

This is the first of four articles on the 2025 German federal elections, continuing our analysis of the 2009, 2013, 2017 and 2021 elections. We begin with the 2023/24 electoral reform, which aimed to curb the uncontrolled growth of the Bundestag caused by political developments not envisaged in...

This is the third out four papers on the 2025 German Bundestag elections continuing our analysis of the 2009, 2013, 2017 and 2021 elections. In particular, this paper contributes to the discussion of the imperfection of the German 2023/24 Electoral reform in [Tangian 2025a]. We show that policy...

Bouton et al. (2022) compare the properties of majority run-off and plurality rule elections in a laboratory setting, focusing on Duverger's prediction that plurality rule leads to higher levels of strategic voting. They produce a causal estimate of the difference in incidence of strategic...

We estimate the causal effect of the electoral system on corruption by leveraging a specificity of the French electoral law where the electoral system for municipal councils depends on municipal population. Specifically, municipalities with fewer than 1,000 inhabitants use an individual majority...

The debate in the European Union (EU) on the expansion of majority decision-making is entering a new round. Germany, in particular, is seeking to build a coalition in favour of more majority decisions in light of the, at times, difficult decision-making process concerning foreign and security...

Majority voting is considered an efficient information aggregation mechanism in committee decision-making. We examine if this holds in environments where voters first need to acquire information from sources of varied quality and cost. In such environments, efficiency may depend on free-riding...

Moya Chin's (2023) paper argues that politicians in two-round majoritarian systems have to appeal more broadly than those in single-round elections. The author uses data for mayoral elections in Brazil. The key findings of the paper conclude that of two-round systems (1) fostering inclusiveness,...

How can women's representation improve in countries that do not embrace legislated gender quotas? We study municipal elections in Turkey during 2009-2019. A conservative dominant party, Erdogan's AKP, is often challenged by a Kurdish party that promotes gender equality in electoral lists....

This paper investigates how direct election regimes (à la presidential democracy) affect the selection of women into political offices compared to indirect appointment (à la parliamentary). Exploiting the staggered phase-in across Italian municipalities of a reform to the local institutional...

We empirically identify politically-motivated redistricting and its consequences, studying the effects of changed electorate composition on US congressional district boundaries and on political outcomes. We exploit the 1986 Immigration Reform and Control Act (IRCA), which legalized millions of...

Electoral quotas for disadvantaged groups aim to promote social justice by ensuring that all groups, including those who are otherwise excluded, participate in the government’s policy-making process. In India, electoral quotas have been in existence since the first election in 1951. An...

I study the consequences for governance of efforts to curb voter-buying. I explore the effects of Brazil’s 2007 voter re-registration reform. Exploiting a discontinuity in the targeting of municipalities assigned to the reform, I examine the response for mayoral elections, public expenditures...

Under majoritarian election systems, securing participation and representation of minorities remains an open problem, made salient in the US by its history of voter suppression. One remedy recommended by the courts is Cumulative Voting (CV): each voter has as many votes as open positions and can...

Theories of political accountability often consider voter-politician interactions in isolation from politician-bureaucrat interactions. We study a model of electoral accountability with a governing hierarchy: voter-politician-bureaucrat. The politician and bureaucrat both produce government...

The fragmentation of the party system has confronted the German mixed-member proportional electoral system with a trilemma. It can only ensure two out of three goals: proportionality, guaranteed representation of district winners, and a fixed and predictable size of the Bundestag. This paper...

This paper attempts to appraise the use of alternative dispute resolution as a panacea to protracted election disputes in Nigeria. The hallmark of democracy in any given society is the conduct of free and fair elections. However, in almost every election, disputes are bound to occur and it is...

We re-analyze the major explanations of redistribution including the Meltzer-Richard (MR) model, power resources theory (PRT), the Iversen-Soskice political institutions explanation, Lupu and Ponstusson's wage inequality skew, along with works suggesting other causes, such as immigration. The...
