Political advertising ethics has long been dominated by an adherence to the norms of democratic idealism or the highly situational ethics of act utilitarianism. This article proposes an alternative system of political advertising ethics grounded in Brandt’s ideal moral code theory, a form of...

We provide causal evidence that immigration has contributed to the polarization of American politics. Using an ancestry-based shift-share instrument, we study immigration flows into U.S. counties between 1992 and 2016. Counties exposed to larger immigrant inflows become more polarized both in...

I study how political parties affect representation in the U.S. House. To do so, I account for party pressure on the votes of members in an otherwise standard spatial model that uses roll call voting patterns to identify member ideologies. I simultaneously estimate voter ideologies from survey...

In an important and much cited study, Pettersson-Lidbom (2008) identifies significant left-wing majority coalition effects on economic outcomes for Swedish local governments, 1974-1994. We first replicate the original study and then extend the original research by applying Pettersson-Lidbom's...

We study the communication strategies on Twitter/X of 367 political leaders in 21 countries, focusing on electoral competition between populists and non-populists. We measure polarization by the ease with which the leader can be classified as populist or not, conditional on his tweet. We find...

Hirschman's Exit, Voice, and Loyalty (1970) proposed that organizations persist when loyalty tempers incentives to exit after adverse shocks. We test this argument using newly digitized individual-level voting records from 28 English constituencies (1832-1868), covering 134,000 real votes....

The parliamentary elections held in Bangladesh on 12 February 2026 marked a turn­ing point in the country’s recent history. In August 2024, Prime Minister Sheikh Hasina, who had served for a total of 20 years, with one interruption, was removed from office. An interim government led by Nobel...

For years, federal politicians from all established parties have categorically ruled out any cooperation with the Alternative for Germany (AfD), erecting a so-called "firewall" ("Brandmauer") against the party. Nevertheless, reports increasingly document instances where this firewall is eroding,...

The European Union operates largely in accordance with the principles of consensus democracy - that is, it seeks to integrate as many parties spanning the political spec­trum of its member states as possible. Amid the recent growth of far-right parties at both the national and European level,...

This study contests the emerging consensus that the educational realignment in voting behavior is centered on non-economic policies. Leveraging comprehensive post-election surveys and party manifesto data, I examine voter responses to previously underexplored dimensions of economic policy - most...

The 20th meeting of the CITES Conference of the Parties (CoP20), scheduled to take place in Samarkand, Uzbekistan, in November-December 2025, will offer Parties the chance to assess how the Convention is being implemented, propose ways to enhance its effectiveness, discuss the resources needed...

This paper investigates whether political partisanship and political narratives affect voters' opinions about public finances. In a novel survey experiment, we test the causal effect of pro-consolidation and pro-public investment narratives used in German general election campaigns on...

In recent years, academic research and public debate have increasingly focused on the relationship between immigration and support for populist radical right-wing parties (PRRPs). This study examines the 2022 Italian National Elections to assess whether the presence of immigrants at municipal...

We study how political parties share power internally by analyzing the allocation of list positions to different factions. We develop a theory of intraparty bargaining in which list positions shape the mobilization efforts of party activists in different factions. Our results allow us to link...

This is the second out of four papers on the 2025 German federal elections continuing our analysis of the 2009, 2013, 2017 and 2021 Bundestag elections. We estimate the policy representation ability of the 29 parties that participated in the 2025 elections and of the 2025 Bundestag. For this...

This is the last out of four papers on the 2025 German federal elections continuing our analysis of the 2009, 2013, 2017 and 2021 Bundestag elections. First, we apply the model from [Tangian 2022b] to construct the 2025 German political spectrum understood as a contiguous party ordering, i.e.,...

We examine whether anti-establishment outsider movements can leverage education and youth mobilization to build long-run political power. We study the expansion of state-run religious secondary schools in 1970s Türkiye and show that access to these schools catalyzed the emergence of Islamist...

In post-war elections a large number of citizens vote for political parties with deep roots in the violent organizations of the past. However, despite the prevalence of rebel, militia, and military successor parties, their success varies dramatically. This study explores the correlates of civil...

Recent controversies over "woke" businesses have challenged traditional partisan political alignments, leading to increased criticism on the right of corporate political activity. This paper explores how the public evaluates corporate political activity, focusing specifically on whether...

Wirtschaftliche Kennzahlen wie das Wirtschaftswachstum sind wichtige Indikatoren zur Bewertung politischer Entscheidungsträger. In den USA hatten Präsidenten der demokratischen Partei höhere Wachstumsraten als die der republikanischen Partei. Dieser Artikel untersucht den Zusammenhang...

Turkey is at risk of descending into autocracy. That risk persists even though the resistance put up by the opposition Republican People’s Party following the arrest of Mayor of İstanbul Ekrem İmamoğlu has saved the party - at least for now - from being placed under a trustee and the...

Ishiba Shigeru became prime minister of Japan in October 2024, after unexpectedly winning the leadership of the ruling Liberal Democratic Party (LDP). His long-desired success came with a bitter aftertaste, however. After a poor showing for the LDP in the lower house elections at the end of...
