Beyond natural sterility, there are two main types of childlessness: one driven by poverty and another by the high opportunity cost to child-rearing. We argue that taking childlessness and its causes into account matters for assessing the impact of development policies on fertility. We measure...

Why in some urban areas do rich and poor households cohabit at the community level while, in others, we observe a sorting by income? To answer this question I develop a two-community general equilibrium framework of school quality, residential choice and tax decision. The model predicts that in...

We study the optimal dynamics of an AK economy where population is uniformly distributed along the unit circle. Locations only differ in initial capital endowments. Despite constant returns to capital, we prove that transition dynamics will set in. In particular, we prove that the...

Since Collier and Hoeffler (1998, 2004), it has been supported that inequality, measured at national level, does not affect the risk of conflict. Based on a renewed theoretical framework, the purpose of the paper is to explore the role of inequality in localized conflicts. We argue that previous...

We investigate how continental European unemployment can be reduced without reducing unemployment benefits and without reducing the net income of low-wage earners. Lower unemployment replacement rates reduce unemployment, the net wage and unemployment benefits. A lower tax on labour increases...

This paper provides an additional channel through which inequality may influence growth, when labor migration is taken into account. In fact, we show that human capital distribution is crucial to determine whether allowing migration of the most skilled workers from a developing country may be...

In most democracies, the majority of education expenditures is financed by the government. In non-democracies, we observe a wide variation in the mix of public and private funding of education. In addition, countries with high inequality tend to rely more heavily on private schooling. We develop...

This paper takes advantage of the availability of rich panel data on the mobility of talented football players, and the performances of national leagues and teams to quantify the effect of the reduction in mobility restrictions, the 1995 Bosman rule, on global efficiency and cross-country...

This paper quantitatively investigates the short- and long-run effects of liberalizing global migration on the world distribution of income. We develop and parametrize a dynamic model of the world economy with endogenous migration, fertility and education decisions. We identify bilateral...

Abstract: The first challenge for economic growth theory is to understand the transition from stagnation to growth at the time of the Industrial Revolution and in particular to identify the main factor(s) that triggered the take-off. Doing so also helps to understand why there are poor and rich...
