In pre-industrial and developing economies, it is common to find (i) entire families, including children, working together in family farms or urban factories; and (ii) a positive link between a person's consumption and her productivity. This paper argues that there is a natural reason for the...

This paper describes and analyzes the results of a unique field experiment especially designed to test the effects of the level of commitment and information available to individuals when sharing risk. We find that limiting exogenously provided commitment is associated with less risk sharing,...
