We find that sequential division of labor and deadlines help alleviate the free rider problem. Conversely,indivisibility of tasks, the number of partners, and asymmetries between agents are shown to increase the expected time to completion. The model may be applied to academic co-authorship, as...

We compute the model numerically to show various possible outcomes. We show solutions where the model eventually leads to relatively equal rewards, and contrast these cases with ones where the long run has persistent differentials. We compute the average reward as a function of the number of...
