Drawing on identity and social comparison theories, we propose and test a model of motivation to lead based on two types of self-to-role comparisons (i.e., self-comparisons with specific leaders and with more abstract representations of the leadership role). We propose that these comparisons...

Social Darwinism suggests that in crisis situations leaders have to be replaced by better fitting leaders. An opposing school argues that leaders, based on their personality, are successful in all situations and therefore can master all situations including a crisis. A third view concludes that...

Santa-Clara and Valkanov (2003) document that excess returns on the stock market are puzzlingly higher under Democratic presidential administrations. We examine whether differences in economic fundamentals can account for this presidential puzzle. We find that the role for fundamentals crucially...

Even after four decades of research it remains unclear, whether presidential popularity depends on the state of the economy. While about half of all studies for the United States find a significant effect of unemployment and inflation on presidential popularity, the others do not. Additional...

In this paper we show that findings of an apparently instable popularity function of U.S. presidents, as reported in the previous literature, are likely the consequence of the common use of linear estimation techniques. Employing Penalized Spline Smoothing in the context of Additive Mixed Models...

A vast labor literature has found evidence of a glass ceiling, whereby women are under-represented among senior management. A key question remains the extent to which this reflects unobserved differences in productivity, preferences, prejudice, or systematically biased beliefs about the ability...

Having leader positions at school, as well as participating in sports and clubs helps promoting valuable non cognitive skills, including leadership, self-discipline, motivation, competitiveness and self-esteem. We use survey data from the US and Japan to investigate whether these behaviors in...

Theoretical models of government formation in political science usually assume that the head of state is non-strategic. In this paper, we analyse the power of an agenda setter who chooses the order in which players are recognised to form coalitions in simple games. We characterise those sets of...

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...
