We develop and estimate an equilibrium job search model of worker careers, allowing for human capital accumulation, employer heterogeneity and individual-level shocks. Wage growth is decomposed into contributions of human capital and job search, within and between jobs. Human capital accumulation is largest for highly educated workers. The contribu...
We develop an equilibrium model of on-the-job search with ex ante heterogeneous workers and firms, aggregate uncertainty, and vacancy creation. The model produces rich dynamics in which the distributions of unemployed workers, vacancies, and worker-firm matches evolve stochastically over time. We prove that the surplus function, which fully charact...
We develop an equilibrium wage-posting model with heterogeneous firms that decide to locate in the formal or the informal sector and workers who search randomly on and off the job. We estimate the model on Brazilian labor force survey data. In equilibrium, firms of equal productivity locate in different sectors, a fact observed in the data. Wages a...
To investigate the evolution of the supply side of the labor market, I derive a methodology to measure an important component of the human capital level of the workforce, the experience of the labor market. Based on the perpetual inventory method, a stock of experience is estimated for eight OECD countries. It appears that, during the last three de...
Dans cet article, nous défendons l’idée que les effets de l’intelligence artificielle (IA) et de l’automatisation sur la croissance et l’emploi dépendent pour une large part des institutions et des politiques. Notre analyse s’articule en deux temps. Dans une première partie, nous démontrons que l’IA peut stimuler la croissance en remplaçant la main...
In this survey paper, we argue that the effects of artificial intelligence (AI) and automation on growth and employment depend to a large extent on institutions and policies. We develop a two‑fold analysis. In a first section, we survey the most recent literature to show that AI can spur growth by replacing labor by capital, both in the production ...
Are agglomeration and peer effects at stake in academic research? To tackle this question, we study how departments’ characteristics affect the quantity and quality of academics’ publications in economics in France, controlling for individual time-varying characteristics and individual fixed effects. Department characteristics have an explanatory p...
S’appuyant sur les nombreuses négociations autour du travail dominical dans le secteur du commerce, cet article a pour objectif d’observer comment les logiques de qualification des salariés s’y renouvellent. La qualification est le produit d’un rapport de forces qui s’actualise constamment au cours des conflits et des négociations au sein des entre...
In the last 30 years wage inequality increased steeply while real minimum wages fell. In this paper I demonstrate that a general equilibrium model with endogenous skill choice is required to correctly evaluate the implications of minimum wage changes. The minimum wage not only truncates the wage distribution, but also affects skill prices and there...
This article focuses on the institutional adjustments that facilitate the routinization of technological opportunities. We propose a life-cycle approach that accounts for the emergence, development, and transformation of new knowledge with special emphasis on the role of adaptive educational and training systems for the diffusion of skills that com...
