This paper extends the Puga (1999) model by introducing urban frictions. It assumes that the agglomeration of manufacturing in a city imposes a cost on the inhabitants of the agglomerated region. Furthermore, an implicit function methodology is developed to provide a numerical stability function...

This paper investigates the employment impact of a new tax-credit programme that was put in place in France in 2001. We study the introduction of both this measure and a later reform in 2004 that made the tax credit cashable in advance upon returning to work. We adopt a non-experimental...

A new algorithm is developed to solve models with heterogeneous agents and aggregate uncertainty that avoids some disadvantages of the prevailing algorithm that strongly relies on simulation techniques and is easier to implement than existing algorithms. A key aspect of the algorithm is a new...

Cette thèse de doctorat s’intéresse au processus d’intégration des immigrés en exploitant des données issues des recensements, qui réunissent à la fois la richesse de la période d’observation (1968-1999) et des groupes d’immigrés (environ une dizaine), et confronte les analyses...

Economists explaining location choices of foreign affiliates usually focus on country-level determinants. Costs of production, the size of expected demand, proxies for agglomeration effects, and various policy-related incentives form the usual set of covariates. Two dimensions of those choices...

L'Organisation Mondiale de la Santé a fait de l'Indice de Masse Corporelle (IMC), rapport du poids sur le carré de la taille, l'instrument privilégié pour l'étude de la corpulence au niveau mondial. Tirant ses origines des travaux d'Adolphe Quetelet dont on lui donne aussi parfois le nom,...

Endogenous labor supply decisions are introduced in an equilibrium model of limited insurance against idiosyncratic shocks. Unlike in the standard case with exogenous labor (e.g. [Aiyagari, S.R., 1994. Uninsured idiosyncratic risk and aggregate saving. Quarterly Journal of Economics 109, 659–684;...

Using time-diary data from 25 countries, we demonstrate that there is a negative relationship between real GDP per capita and the female-male difference in total work time per day – the sum of work for pay and work at home. In rich northern countries on four continents, including the United...

A lack of political leadership is often perceived as the main source of the repeated difficulties of the WTO. The paper argues that such a lack of leadership is a systemic problem for many years to come. The large industrial democracies have constitutional rules making particularly difficult...

In this paper we develop a new empirical approach to uncovering the impact of social attitudes on economic development. We first show that trust of second-generation Americans is significantly influenced by the country of origin of their forebears. In the spirit of the epidemiology literature,...
