We explore the relationship between aggregate relative poverty and migration. We draw upon Polish regional data and use a measure of aggregate relative poverty that is functionally related to the Gini coefficient. We find that the Gini coefficient and migration are positively correlated, holding...

The authors examine the importance of absolute income and relative deprivation incentives for internal and international migration in developing country households. Empirical results, based on Mexican village data, support the hypothesis that households'relative deprivation in the village...

We demonstrate how altruism can flourish in a population of nonaltruists. We assume that each individual plays a one-shot prisoner's dilemma game with his or her sibling and that the probability than an individual survives to reproduce is proportional to his or her payoff in this game. We model...

We study human capital depletion and formation in an economy open to out-migration, as opposed to an economy which is closed. Under the natural assumption of asymmetric information, the enlarged opportunities and the associated different structure of incentives can give rise to a brain gain in...

We offer a game-theoretic proof of Hamilton's rule for the spread of altruism. For a simple case of siblings, we show that the rule can be derived as the outcome of a one-shot prisoner's dilemma game between siblings.
