Aggarwal et al. (2023) analyze the effects of an 8-month-long advertising program on voter turnout in the 2020 US presidential election. Therein, 2 million voters were exposed to pro-Biden and anti-Trump advertisements on social media in five battleground states. The study finds no average...

As fringe parties increasingly capture a larger portion of the votes, the issue of how centrist parties can set themselves apart from these extremes while establishing distinct characteristics has become more prominent in public and political debates. Despite analyses of programmatic overlaps...

Intra-party contests, such as the US primaries, are often used to select a candidate for a subsequent cross-party election. A more accurate selection may improve the quality of the candidate but detract more resources from the subsequent campaign. We model this trade-off as a problem of contest...

Lee (2022) evaluates whether elected officials update their policy positions based on expert evidence. His cross-subject and within-subject designs run in the American local and state policy-making context both confirm the capacity for politicians to update their beliefs in response to expert...

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,...

Die Alterung der deutschen Bevölkerung führt in der umlagefinanzierten Gesetzlichen Rentenversicherung zu höheren Beiträgen bei sinkendem Sicherungsniveau. Dies ließe sich bremsen, wenn mit steigender Regelaltersgrenze der Renteneintritt später erfolgte. Jedoch bevorzugt die Bevölkerung...

U.S. congressional roll-call voting records show that as polarization of the two parties along the economic dimension changes, polarization along the social/cultural dimension tends to change in the opposite direction. A model of party competition within a two-dimensional ideology space is...

We develop a model of elections in which parties choose their ideological position and the ideology of their candidates. Tighter candidate selection reduces policy uncertainty for voters. We show that weak institutional constraints, as in a Presidential regime, induce parties to allow their...

Die NSDAP kopierte nicht nur von Anfang an den Stil der Arbeiterbewegung, sondernverlagerte auch den Schwerpunkt ihrer Propaganda ab 1928 von nationalistischer Außenpolitikauf innenpolitische und soziale Fragen. Bis 1932 wurde diese Ausrichtung jedoch durchkein wirtschaftspolitisches Programm...

We study the effects of social media political advertising by randomizing subsets of 36,906 Facebook users and 25,925 Instagram users to have political ads removed from their news feeds for six weeks before the 2020 US presidential election. We show that most presidential ads were targeted...

Innerparteiliche Demokratie ist innerparteiliche Wettbewerbsdemokratie. Die grundgesetzliche Demokratie kann als System wettbewerblicher Interessenaggregation beschrieben werden. Art. 21 Abs. 1 S. 3 GG überführt diese wettbewerbliche Demokratiekonzeption in die Parteien; sie prägt deren...

The present paper draws the attention of political scientists towards the participation of the European Parliament in EU legislation making on migration and in the EU management of the migration crisis of the last seven years. The paper aims at knowing whether and, in the positive case, why the...

The last few decades witnessed a dramatic change in public opinion towards gay people. This paper studies the hypothesis that the AIDS epidemic was a shock that changed the incentive to "come out" and that the ensuing process of mobilization and endogenous political process led to cultural...

In most national elections, voters face a key choice between continuity and change. Electoral turnovers occur when the incumbent candidate or party fails to win reelection. To understand how turnovers affect national outcomes, we study the universe of presidential and parliamentary elections...

The role of citizens' initiatives figures prominently in contemporary debates on constitutional change. A basic question is why are initiatives necessary in a representative democracy where candidates must already compete for the right to control policy? This paper offers one answer to this...

Individual members of Congress can have different policy preferences from the party leadership or special interest groups (SIGs), and the latter two may pressure members to shift their positions. To study this tension, we develop and estimate a multi-stage election model that incorporates party...

Luisa Dörr prepared this study while she was working at the ifo Center for Public Finance and Political Economy. The study was completed in February 2022 and accepted as doctoral thesis by the Department of Economics at the University of Munich. It consists of three distinct empirical essays...

Wirtschaftspolitik in einer sozialen Marktwirtschaft möchte Wohlstand schaffen und verteilen. Dies zeigt sich in den Wahl- und Regierungsprogrammen auf Bundesebene seit 2002, allerdings mit sehr unterschiedlichen Akzenten. Zur Analyse wird deshalb die relative Häufigkeit der Begriffe...

Democratic representation is constrained by the alternatives available to voters. In this paper, we develop a methodology to gauge the extent to which the "supply side" of politics hinders voter welfare. Using rich data on thousands of candidates in three Brazilian legislative elections, we...

How important are political parties in motivating and disciplining elected officials? Using a difference-in-discontinuity design, we study how shocks to incumbents're-election probabilities affect legislative behavior in a setting where parties fully control candidate selection. We find that...

We develop a model of elections in which parties choose their ideological position and the ideology of their candidates. Tighter candidate selection reduces policy uncertainty for voters. We show that weak institutional con- straints, as in a Presidential regime, induce parties to allow their...

We review an empirical literature that studies how political polarization affects financial decisions. We first discuss the degree of partisan segregation in finance and corporate America, the mechanisms through which partisanship may influence financial decisions, and available data sources to...

The Federal Reserve Act was the outcome of compromises among competing economic and political interests. Numerous studies examine how the act came together but largely take the makeup of Congress and the Administration as given rather than considering the unique circumstances that led to that...

I analyze the link between partisan alignment of local politicians and the incidence of political corruption, using novel hand-collected data on local political corruption in Ghana. In line with political ambition theory, I hypothesize that local politicians aligned with the national government...

Vier Parteien - Die Linke, SPD, Bündnis 90/Die Grünen und FDP - haben bis Ende April 2021 den Entwurf ihres Programms zur Bundestagswahl am 26. September veröffentlicht. Wie klar und überzeugend vermitteln Bundestagsparteien ihre Vorstellungen? Die digital- und medienpolitischen Aussagen der...
