Strong ties with the home country and with the host country can coexist. An altruistic migrant who sends remittances to his family back home assimilates more the more altruistic he is, and also more than a non-remitting migrant.

In the model of Stark et al. (1997, 1998), the possibility of employment in a developed country raises the level of human capital acquired by workers in the developing country. We show that this result holds even when workers have the option to save.

Strong ties with the home country and with the host country can coexist. An altruistic migrant who sends remittances to his family back home assimilates more the more altruistic he is, and also more than a non-remitting migrant.

We study a policy response to an increase in post-merger social stress. If a merger of groups of people is viewed as a revision of their social space, then the merger alters people's comparators and increases social stress: the social stress of a merged population is greater than the sum of the...

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...

This paper looks at the integration of regions and nations through the prism of the merger of populations (societies). The paper employs a particular index of social stress. Stylized examples of the merging of two populations suggest that with integration, the social stress index will increase....

In determining the optimal redistribution of a given population's income, we ask which factor is more important: the social planner's aversion to inequality, embedded in an isoelastic social welfare function indexed by a parameter alpha, or the individuals' concern at having a low relative...

This paper explores the following chain of conjectures: rising use of the internet, the widespread access to global information, and intensified communication between regions and countries brought about, for example, by intensified trade links bring about expansion of people's social space and...
