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...

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...

Social comparisons are important in the employment sphere. A "culture of unemployment" may evolve and prevail because it is optimal for an individual to remain unemployed when other unemployed individuals constitute his main reference group. We advance the idea that by making the receipt of...

We present a theory that systematically and causally links the well-being of native inhabitants with variation in the extent of the assimilation of migrants. Recent empirical findings are yielded as predictions of the theory.

When individuals’ utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...

This discussion paper investigates the impact of the imposition of sanctions for employing illegal migrants on the welfare of native laborers. In response to such sanctions, managers in a firm may be reassigned from the supervision of production to the verification of the legality of the firm's...

We develop a formula for the optimal size of a joint savings association between individuals who share the same financial goal and who can save towards that goal at the same rate. Our motivating example and the core of our analysis is a Rotating Savings and Credit Association (ROSCA). We measure...

In this paper we consider a population of would-be migrants in a developing country. To begin with, this population is divided into two sets: those who save by themselves to pay for the cost of their migration, and those who pool their savings with the savings of another would-be migrant to pay...

We study the assimilation behavior of a group of migrants who live in a city populated by native inhabitants. We conceptualize the group as a community, and the city as a social space. Assimilation increases the productivity of migrants and, consequently, their earnings. However, assimilation...

We consider a tax-funded policy of admitting and integrating asylum seekers in a country in which the incomes of the native inhabitants are differentiated; for the sake of simplicity, we assume that there are just two groups of native inhabitants: high-income natives and low-income natives. As a...
