In an asymmetric tournament model with endogenous risk choice by the agents it is shown that equilibrium efforts decrease (increase) with risk if abilities are sufficiently similar (different). Risk also affects winning probabilities. The interaction of both effects is analyzed.

It is well-known that, in static models, minimum wages generate positive worker rents and, consequently, inefficiently low effort. We show that this result does not necessarily extend to a dynamic context. The reason is that, in repeated employment relationships, firms may exploit workers future...
