In this paper, we explore the reproducibility of the König et al. (2022) paper on the timing of bill initiation under coalition governments and validate its scope condition by expanding the analysis to an additional government and country, namely the United Kingdom's Conservative-Liberal...

Radical right parties (RRPs) have gained representation in parliaments across Europe, but little is known about their impact on government policy. Even though RRPs tend to end up in opposition, they have considerable influence on policy making within coalition governments. One expectation is...

Does policy-making in coalition governments affect cabinet parties’ electoral performance? Previous research shows that about two thirds of all propositions promised in coalition agreements are actually enacted. But does non-compliance with pledges made in the agreement affect subsequent...

There are multiple models of party formation in the political economy literature. However, most of these works consider individuals as parties and do not model parties as a group of candidates. In this paper, we follow the latter approach and assume that parties form as a result of mutually...

Electoral thresholds in the context of parliamentary elections are an instrument for preventing the fragmentation of parliaments and facilitate the formation of a coalition government. However, the clauses also introduce distortions and modify the equality of electoral votes in an election. In...

This is the first out of four papers devoted to the 2021 German federal elections continuing our analysis of the 2009, 2013 and 2017 Bundestag elections by the methods of the mathematical theory of democracy. This one estimates the policy representation ability of the 39 parties that...

This study theorises the political system after the introduction of democracy through one mechanism: federalism and coalition government. This study shows that if a stable ruling party can be constituted by a coalition government without a federal system, then either the coalition government is...

We study a game theoretic model of a parliamentary democracy under proportional representation where ideologically motivated citizen groups form parties, voting occurs and governments are formed. We study the coalition governments that emerge as functions of the parties' seat shares, the size of...

We study how partisan alignment across levels of government affects coalition formation and government stability using a regression discontinuity design and a large dataset of Spanish municipal elections. We document a positive effect of alignment on both government formation and stability....

In modern realities, a new wave of interest in socialist ideas is emerging, which is reflected not only in the economy, but also in the spheres of culture and art (the case of rapper Pablo Hasel, his Marxist and pro-Soviet discourse received great publicity and public resonance).The locomotive...

How do multiethnic coalitions affect the risk of violent conflict? We argue that government leaders form larger ruling coalitions as the uncertainty over violent threats from radical sub-groups increases. We formalize this argument in a novel multi-actor model. Our game-theoretic approach...

Der am 24. November 2021 vorgestellte Koalitionsvertrag 2021-2025 von SPD, Bündnis 90/Die Grünen und FDP sieht eine Reihe von sozial- und steuerpolitischen Maßnahmen vor. Das ZEW Mannheim hat für die Süddeutsche Zeitung die Wirkungen der Reformpläne untersucht. Die Analyse betrachtet die...

We present a theoretical model of a parliamentary democracy, where party structures, government coalitions and fiscal policies are endogenously determined. The model predicts that, relative to proportional elections, majoritarian elections reduce government spending because they reduce party...

Although parties' preferences for office and policy goals have been featured by many rational choice models of party behavior and a majority of coalition theories, the literature still lacks a measure and a comprehensive analysis of how parties' preferences vary among parties and across...

The fiscal commons problem is one of the most prominent explanations of excessive spending and indebtedness in political economics. The more fragmented a government, the higher its spending, deficits and debt. In this paper we investigate to what extent this problem can be mitigated by different...

This paper examines the importance of electoral rules for legislators' behavior. The German electoral system includes a mechanism which assigns whether legislators are elected under the "first-past-the-post" (FPTP), or the proportional representation (PR) electoral rule. Using this institution,...

The coalition literature has thrived during the 20th century, and now constitutes not only a consolidated field in political science, but also one of the most productive fields in terms of theoretical and methodological approaches. Throughout this history, coalition models have played a key role...

The effective number of political parties (ENP) in a single member plurality rule electoral system is analyzed as a dynamic process whereby the tournament nature of the election contest induces excessive entry and sunk entry costs promote persistence even as Duverger-Demsetz type political...

We study a model in which agents endowed with power compete for a divisible resource by forming coalitions with other agents. The coalition with the greatest power wins the resource and divides it among its members via proportional sharing. We conduct an economic experiment using this model to...

Die Bundesregierung ist derzeit nicht nur bemüht, die Vereinbarungen aus dem Koalitionsvertrag umzusetzen, sondern plant darüber hinaus weitere Gesetzesvorhaben. Doch gleichzeitig lässt das Wachstum der Steuereinnahmen nach. So übersteigen die resultierenden Mehrausgaben den...

In this article, we empirically study the survival of the ruling party in parliamentary democracies using a hazard rate model. We define survival of a crisis as being successful in a critical vote in the parliament. We develop a general probabilistic model of political crises and test it...

In der Februar-Umfrage des Ökonomenpanels von ifo und FAZ wurden Professoren für Volkswirtschaftslehre an deutschen Universitäten zu den Ergebnissen der Sondierungsgespräche zwischen CDU/CSU und SPD befragt. Eine Mehrzahl der Teilnehmer zeigte sich weitgehend enttäuscht von diesen...

In vielen deutschen Städten ist die Vergabe von freien Plätzen in Kindertagesstätten langwierig und daher mit erheblicher Planungsunsicherheit für Eltern und Verwaltungsaufwand für Kita-Personal verbunden. Gerade der akute Mangel an Betreuungsplätzen führt zu Konkurrenz um Kitaplätze und...

Union und SPD haben sich auf zahlreiche Ausgabenprojekte verständigt. Das Finanztableau im Koalitionsvertrag für die Jahre 2018 bis 2021 entspricht zwar dem von der Regierung geschätzten Handlungsspielraum. Dabei verschweigen die Koalitionäre jedoch, dass die vereinbarte Ausgabendynamik...

Social trust has been identified as a catalyst for reforms. We take the literature further in two ways. First, we make a fine-grained analysis of mechanisms through which social trust enables liberalizing reforms - by strengthening the ability to overcome obstacles in the political process...

Despite the extensive literature on distributive politics, we still lack a theory of how political and fiscal institutions interact to shape the pork‐barrelling ability of national leaders in a federal parliamentary democracy. Focusing on party system attributes and governmental incentives...

The paper estimates the policy representation of 34 German parties that participate in the 2017 Bundestag (federal) election. For this purpose, the party positions on 31 topical issues are compared with the results of recent public opinion polls. Then we construct the party indices of popularity...
