Do Skilled Migrants Compete with Native Workers? Analysis of a Selective Immigration Policy
In recent years Western countries are expressing growing concerns about the regulation of migration flows and many are considering adopting some form of selective immigration policy. This paper analyzes the labor market effects of one of such reforms introduced in France in 2008 with the aim of encouraging the inflow of foreign workers with skills that are scarce among the local labor force. The analysis relies on administrative employer-employee data 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 causing any harm to native employment. As a result, the overall stock of labor grew in these jobs. Entry wages are lowered by 4% among natives and by 9% among foreigners, suggesting that these two groups may not be perfect substitutes, even when they are employed for the exact same task. The effects are stronger for the occupations with the most severe lack of native candidates and for those with an average salary largely above the minimum wage, indicating that the reform was successful in attracting candidates with rare skills and relatively high productivity.

The Formation and Malleability of Dietary Habits: A Field Experiment with Low Income Families
écrit avec Noemi Berlin, Jonathan James and Valeria Skafida
We conduct a field experiment to evaluate the short and long term effects of two interventions targeting the dietary habits of low income families with young children. In one treatment, families received food groceries at home for free for twelve weeks and were asked to prepare five specific healthy meals per week. In the other treatment, families were simply asked to reduce snacking and eat at regular times, also for twelve weeks. We evaluate the impact of the interventions on diet and BMI over the course of three years. We find evidence that children's BMI distribution shifted significantly relative to the control group, i.e. they became relatively ``thinner''. This effect persists three years after the intervention for the first intervention, but fades away for the second. We find evidence that children reduced their sugar intake following both treatments. However, we find little evidence that their preferences changed in favor of healthier foods. A possible explanation is that children were restricted access to foods high in sugar in the treated groups. Parents, on the other hand, do not appear to have changed their diet as a result of the interventions, neither in the short run nor in the longer run.
