We analyze a game in which a group of agents exert costly effort over time to make progress on a project. The project is completed once the cumulative efforts reach a pre-specified threshold, at which point it generates a lump sum payoff. We characterize a budget balanced mechanism that induces...

We consider a stochastic tournament game in which each player is rewarded basedon her rank in terms of the completion time of her own task and is subject to cost of effort. When players are homogeneous and the rewards are purely rank dependent, the equilibrium has a surprisingly explicit...
