Es gibt in Deutschland bisher wenige Erhebungen dazu, wie Politiker:innen wissenschaftliche Erkenntnisse für ihre Arbeit nutzen. Um diese Kenntnislücke zu füllen, hat die Nationale Akademie der Wissenschaften Leopoldina eine Erhebung beauftragt, die sich an die Mitglieder des Deutschen...

We examine the stock trading behavior and returns of U.S. senators from 2012-March 2020. Stocks purchased by senators on average slightly underperform stocks in the same industry and size (market cap) categories by 11 basis points, 28 basis points and 17 basis points at the 1, 3, and 6-month...

Der Deutsche Bundestag umfasst gegenwärtig 709 Abgeordnete. In keiner Legislaturperiode zuvor waren es so viele. Schließlich liegt die Sollstärke bei 598 Abgeordneten – 299 direkt gewählte Abgeordnete aus den Wahl­kreisen und ebenso 299 Abgeordnete, die über die Liste ins Parlament...

We link future members of Congress to the de-anonymized 1940 census to offer a uniquely detailed analysis of how economically unrepresentative American politicians were in the 20th century, and why. Future members under the age of 18 in 1940 grew up in households with parents who earned more...

We analyze data from an author‐conducted survey of members of the French and German parliaments on European Monetary Union reform preferences. We consider three potential drivers of preferences: nationality, ideology, and personal characteristics. For European Monetary Union policies like...

This paper presents the first empirical analysis of the impact of Parliamentary immunity on the behavior and performance of politicians. Leveraging a Constitutional Amendment, the adoption of which lifted the immunity of 132 of the 550 members of the Turkish Parliament, we find that losing...

Aktuell stehen Gesellschaft und Politik vor grossen Aufgaben wie Klimakatastrophe, demografischer Wandel und soziale Ungleichheit: Wenn der Einfluss der Wirtschaft auf politische Entscheidungsprozesse in Bundestag und Ministerien nicht radikal begrenzt wird, sind diese Zukunftsfragen nicht zu lösen

Werden Bundestagsabgeordnete von ihren Parteien abgestraft, wenn sie in namentlichen Abstimmungen im Bundestag nicht mit ihrer Partei stimmen? Betrachtet wurden alle 218 namentlichen Abstimmungen in der Legislaturperiode 2009–2013 für 257 über die Liste in den Bundestag eingezogene...

We examine whether parties punish politicians who vote against the party line in roll-call votes. Using data of German members of parliament over the legislative period 2009-2013, we take into account that the effect of punishment differs along the list of candidates because a candidate is...

An important question in representative democracies is how to ensure that politicians behave in the best interest of citizens rather than their own private interests. Aside from elections, one of the few institutional devices available to regulate the actions of politicians is their pay...

We measure where and to what end parties take control of Congressional redistricting, which lets them redraw districts to favor their own candidates. We exploit the discontinuous change in a party's control of redistricting triggered when its share of seats in the state legislature exceeds 50...

This thesis comprises four empirical research papers in the area of political economics. While the first two chapters deal with questions related to direct democracy, chapters three and four are about topics linked to representative democracy.

The Brexit referendum and the decision of British voters to leave the EU have sparked a comprehensive debate on the future of European integration. A key issue in this debate is the appropriate division of responsibilities between the EU and its Member States. The EU might still lack certain...

This paper uses data on bill sponsorship and cosponsorship in the U.S. House of Representatives to estimate gender differences in cooperative behavior. We employ a number of econometric methodologies to address the potential selection of female representatives into electoral districts with...

This study provides a comprehensive, accurate and ready-to-use dataset on the relationships between the members of the Swiss Parliament and groups of interests. We capture politicians' linkages exploiting (1) their mandates in legal entities; (2) the enterprises, associations or other...

Attorneys elected to the US Congress and to US state legislatures are systematically less likely to vote in favor of tort reforms that restrict tort litigation, but more likely to support bills that extend tort law than legislators with a different professional background. This finding is based...

Die Bürgerinnen und die Bürger können im Staat nicht alles selbst entscheiden. Sie brauchen Repräsentanten. Charles B. Blankart, Humboldt-Universität zu Berlin und Universität Luzern, und Dennis C. Mueller, Universität Wien, stellen in ihrem Kommentar fünf Regierungsmodelle vor und...

Eine neue Studie untersucht, ob Nebeneinkünfte die politische Tätigkeit von Bundestagsabgeordneten beeinträchtigen. Die Ergebnisse zeigen nicht, dass Nebeneinkünfte mit der Abwesenheit in namentlichen Abstimmungen und der Zahl der Reden im Parlament korrelieren. Es gibt jedoch eine negative...

We examine moonlighting by politicians in Germany. In July 2007, the German Supreme Court adjudicated that members of parliament (MPs) have to publish details of their outside earnings. Using panel data models, we investigate how outside earnings are correlated with absence and parliamentary...

Attorneys elected to the US House of Representatives and to US state legislatures are systematically less likely to vote in favor of tort reforms that restrict tort litigation, but more likely to support bills that extend tort law. This finding is based on the analysis of 54 votes at the federal...
