Consider a population of farmers who live around a lake. Each farmer engages in trade with his m adjacent neighbors, where m is termed the span of interaction. Trade is governed by a prisoner's dilemma rule of engagement. A farmer's payoff is the sum of the payoffs from the m prisoner's dilemma...

Let a society's unhappiness be measured by the aggregate of the levels of relative deprivation of its members. When two societies of equal size, F and M, merge, unhappiness in the merged society is shown to be higher than the sum of the levels of unhappiness in the constituent societies when...

This paper identifies the migration policies that emerge when both the sending country and the receiving country wield power to set migration quotas, when controlling migration is costly, and when the decision how much human capital to acquire depends, among other things, on the migration...

This paper develops a model of voluntary migration into degrading work. The essence of the model is a tension between two bads that which arises from being relatively deprived at home, and that which arises from engaging in humiliating work away from home. Balancing between these two bads can...

In this paper I study policy responses to an increase in post-merger distress. I consider the integration of regions and nations as a merger of populations which I view as a revision of social space, and I identify the effect of the merger on aggregate distress. The paper is based on the premise...

We relate to others in two important ways: we care about others, and we care about how we fare in comparison to others. In some contexts, these two forms of relatedness interact. Caring about others can conveniently be labeled altruism. Caring about how we fare in comparison with others who fare...

Under a deadweight loss of tax and transfer, there is tension between the optimal policy choices of a Rawlsian social planner and a utilitarian social planner. However, when with a weight greater than a certain critical value the individuals' utility functions incorporate distaste for low...

We study the impact of gender quotas on the acquisition of human capital. We assume that individuals' formation of human capital is influenced by the prospect of landing high-pay top positions, and that these positions are regulated by gender-specific quotas. In the absence of quotas, women...

Recent research shows that the merger of economies increases aggregate stress. This paper shows that there is no income distribution policy which will ensure that the wellbeing of the individuals belonging to merging economies does not fall below their pre-merger level.

Let there be two individuals: "rich," and "poor." Due to inefficiency of the income redistribution policy, if a social planner were to tax the rich in order to transfer to the poor, only a fraction of the taxed income would be given to the poor. Under such inefficiency and a standard utility...
