We use data from professional tennis to measure the causal effect of past on current performance for women and men. Identification relies on exogenous shocks to the probability of facing a contested game, which is a previous stage of competition with strong resistance. We find fundamental gender...

One of the most conspicuous features of mergers is that they come in waves that are correlated with increases in share prices and price/earnings ratios. We use a natural way to discriminate between pure stock market influences on firm decisions and other influences by examining merger patterns...

To estimate demand for labor, we use a combination of detailed employment data and the outcomes of procurement auctions, and compare the employment of the winner of an auction with the employment of the second ranked firm (i.e. the runner-up firm). Assuming similar ex-ante winning probabilities...

We use data from top-level soccer to examine determinants of individual misbehaviour in team contests. Our estimates indicate a significant positive and non-linear relationship between a player's age and (relative) ability on the one hand and the tendency to misbehave on the other. These...

This study analyses whether the decision to work while sick can be linked to workload fluctuations. Drawing on data collected from professional football, we exploit the dynamics of a season and use additional (national and international) cup games conducted in the second half of a season as a...

We study the effect of the size of the welfare state on family outcomes in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e. the number of relevant parties involved in the legislative process), we show...

Does the supply of a welfare state create its own demand? Many economic scholars studying welfare arrangements refer to Say's law and insinuate a self-destructive welfare state. However, little is known about the empirical validity of these assumptions and hypotheses. We study the dynamic effect...

We analyze if female athletes differ from male athletes in their competitive behavior, using data from high jump and pole vault competitions. We estimate if female athletes use risky strategies as often as male athletes and whether or not their returns to risky strategies differ. Returns to...
