A country's form of government has important economic and political consequences, but the determinants that lead countries to choose either parliamentary or presidential systems are largely unexplored. This paper studies this choice by analyzing the factors that make countries switch from...

During the last decade unicameral proposals have been put forward in fourteen US states. In this paper we propose a theoretical framework casting some lights on the drawbacks of bicameral state legislatures and on the effects of the proposed constitutional reforms. In a setting where lawmakers...

We study political polarization in a parliamentary setting dominated by strong parties. In addition to examining polarization along the left-right dimension, we consider political divergence between legislators belonging to the same political bloc. Are politicians’ background characteristics...

Far-right and far-left parties by definition occupy the fringes of politics, with policy proposals outside the mainstream. This paper asks how public attitudes about such policies respond once an extreme party increases their political representation at the local level. We study attitudes...

The standard assumption of exogenous policy preferences implies that parties set their positions according to their voters’ preferences. We investigate the reverse effect: Are the electorates’ policy preferences responsive to party positions? In a representative German survey, we inform...

Is politics a lucrative business? The question is approached in this paper, as one of few to quantify the monetary returns to holding political office in a typical developed democracy where parties are the main political actors. By applying a difference-in-difference setting with a carefully...

We assess the influence of moneyed interests on legislative decisions. Our theory predicts that the vote outcome distribution and donation flows in a legislature feature a discontinuity at the approval threshold of bills if special interest groups are involved in vote buying. Testing the...

We document a remarkable increase over the past two and a half decades in the fraction of people in England feeling close to no party – the rise of the “no party” – which, today, is close to constituting an absolute majority. We develop a new method to distinguish between age, period,...

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...

Does party competition affect political activism? This paper studies the decision of party supporters to join political campaigns. We present a framework that incorporates supporters' instrumental and expressive motives and illustrates that party competition can either increase or decrease party...
