Labor Market Consequences of Selective Immigration Policy, Analysis of a French Reform


In a context of increasing concerns about how to regulate migration flows, many Western countries are considering adopting some form of selective policies. This paper analyzes the effects of a reform introduced in France in 2008, aiming at facilitating the recruitment of foreign workers in occupations experiencing hiring difficulties due to the lack of competent candidates. In particular, it evaluates whether it increased the inflows of foreign labor, and asks whether this generated a negative pressure on local employment and wages. The analysis relies on two large administrative datasets recording labor movements, stocks of employees and wages within French firms, and it is based on a difference-in-differences approach. Results show that the reform increased the hiring of foreign workers in target occupations without harming native employment prospects. On the other hand, the entry salary in these jobs is diminished by about 3%, which can be seen as a direct consequence of the relief of the tension.



Technological and Organizational Change and the Fall of Occupational Mobility, a Tale of Four Industrialized Countries (with Eric Maurin)


Since the 1980s the labor markets of most industrialized countries have undergone important structural transformations. Technological change and globalization have transformed the production function of firms and have shifted their labor demand away from easily automatable occupations towards high-skill professions. While a growing number of papers analyzes the impacts of such shifts on the structure of the economy, few are the ones that look at how the careers of workers are affected in the long run. This paper aims to fill this gap by establishing a link between the recent technological and organizational changes and the occupational mobility of employees.
