We explore the impact of health shocks on criminal behavior. Exploiting variations in the timing of cancer diagnoses, we find that health shocks elicit an increase in the probability of committing crime by 13%. This response is economically significant at both the extensive (first-time...

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...
