Deterrence institutions are widely used in modern societies to discourage rule violations but whether they have an impact beyond their immediate scope of application is usually ignored. Using a quasi-experiment, we found evidence of spillover effects across contexts. We identified fraudsters and...

We study a dynamic variant of the die-under-the-cup task where players can repeatedly misreport the outcomes of consecutive die rolls to earn more money, either under a non- competitive piece rate scheme or in a two-player competitive tournament. In this dynamic setting we test (i) whether...
