We investigate a setting in which members of a population, bifurcated into a majority and a minority, transact with randomly matched partners. All members are uniformly altruistic, and each transaction can be carried out cooperatively or through a market mechanism, with cooperative transactions...

The demographic history of the Jews in the Middle Ages may be characterized by two main phenomena: i) a sharp drop in the number of Jews until the beginning of the modern period, due mainly to conversions; and, ii) early urbanization. Until now, these features have been analyzed as primarily...

This paper presents a first attempt at understanding some of the many issues involved in the granting of an amnesty to illegal immigrants. We consider government behavior with respect to allocations on limiting infiltration (border control) and apprehending infiltrators (internal control) and...

How do immigrants promote exports? To answer this question we propose a unified empirical framework allowing to identify and disentangle the main mechanisms put forth in the literature: the role of networks in reducing bilateral transaction costs, and the productivity shifts arising from...

Using provisions to ease the movement of business visitors in trade agreements, we show that removing barriers to the movement of business people promotes trade. We document the increasing complexity of Free Trade Agreements and develop an algorithm that combines machine learning and text...

We develop a model of the interdependencies between migration, remittances and inequality, and investigate how migration and subsequent remittances affect inter-household inequality in the origin communities. An important feature of our model is that we take into account the impact of migration...

We present an empirical evaluation of the growth effects of the brain drain for the source countries of migrants. Using recent US data on migration rates by education levels (Carrington and Detragiache, 1998), we find empirical support for the ?beneficial brain drain hypothesis? in a...
