We build a model of conflict in which two groups contest a resource and must decide on the optimal allocation of labor between fighting and productive activities. In this setting, a diaspora emanating from one of the two groups can get actively involved in the conflict by transferring financial...

This study adapts a relatively novel model of off-farm labor supply to the changing conditions of Bulgaria during the 1990s. The model's parameters are estimated separately for each of the three different waves of the Bulgarian Integrated Household Survey, each reflecting remarkably different...
