The inclination of individuals to improve their performance when it lags behind that of others with whom they naturally compare themselves can be harnessed to optimize the individuals' effort in work and study. In a given set of individuals, we characterize each individual by his relative...

This paper adds three dimensions to the received literature: it models migration when the individuals' preferences regarding their relative income are ordinal, it works out the resulting spatial steady state distribution of the individuals, and it shows that the aggregate of the individuals'...

We introduce a new class of generalized measures of relative deprivation. The class takes the form of a power mean of order p . A characteristic of the class is that depending on the value of the proximity-sensitive parameter p, the class is capable of accommodating both a decreasing weight (the...

We ask which migration policy a developed country will choose when its objective is to attain the optimal skill composition of the country's workforce, and when the policy menu consists of an entry fee and a quota. We compare these two policies under the assumptions that individuals are...

Evidence is presented in support of the “brain gain” view that the likelihood of migrating to a destination wherein the returns to human capital (schooling) are high creates incentives to acquire human capital in migrant-sending areas. In Mexico, even though internal migrants are more...

We model group formation as a response to relative deprivation. We employ two measures of relative deprivation. We show that in the case of each of these measures the process of deprivation-induced self-selection into groups reaches a steady state, and that the steady-state distribution differs...

This paper argues that an increase in the inequality of wealth prompts a stronger quest for status that in turn fosters the accumulation of wealth. It proposes a measure for an individual's want of social status. For a given level of a population's wealth, the corresponding aggregate measure of...

Received research shows numerous motives for migration, but fewer reasons for return migration. This paper aims to correct this imbalance. Twelve reasons for return migration are presented and discussed briefly. The reasons listed are derived from research on migration conducted by the author in...

A rationale for providing support to the farm sector in the course of economic development and structural change is a growing gap between the incomes of non-agricultural workers and the incomes of farmers. Drawing on a model that enables us to analyze the level of social stress experienced by...

Acknowledging individuals' distaste for low relative income renders trade less appealing when trade is viewed as a technology that integrates economies by merging separate social spheres into one. We define a “trembling trade” as a situation in which gains from trade are overtaken by losses...
