This paper examines how immigration affects native wages by exploiting an unexpected episode of immigrant influx. The episode happened in Hong Kong, when its government unexpectedly relaxed the restriction on immigration from mainland China in 1993, resulting in a seven-fold increase in the net...

A firm\'s export status may improve its capacity of introducing product innovations. We explore this idea using very rich firm-level data on Italian A firm\'s export status may improve its capacity of introducing product innovations. We explore this idea using very rich firm-level data on...

Empirical evidence suggests that sectoral export growth decreases exporters\' survival probability, whereas non{exporters are unaffected. Models with firm heterogeneity in total factor productivity predict the opposite. To solve this puzzle, we develop a two-factor framework where firms differ...

Public enterprises are production units of goods or services under government control. In spite of wide privatizations in the last two decades, public provision in this form can be observed in many countries and sectors, particularly in education, health, transport, energy and environment. This...

We study the migration policy set by a welfare maximizing government in a model where immigrant workers differ in their skills and are imperfectly matched with heterogenous occupations. The policy fixes a minimum skill level for legal migrants, and foreign workers that fall below it can only...

Global international migration may influence child labor through a labor market effect. We empirically investigate this issue by using an original cross-country survey dataset, which combines information on international emigration flows with detailed individual-level data on child labor at age...

Assume that government maximizes the well being of its citizens subject to technological, political, and informational constraints. How should equilibrium be perturbed so that equilibrium post-perturbation quantities satisfy new exogenously-specified bounds? We prove an intervention principle...

Using data on cross border transactions together with an informative measure of financing constraints this paper provides new evidence that limited access to external capital narrows the scale of foreign sales, the exporters’ product scope and the number of trade partners. It shows that...

We merge German balance-of-payments and foreign-affiliate-trade statistics to obtain data about trade in commercial services at the firm level. We use these data to study export market participation and the choice of export mode: cross-border versus foreign affiliate sales. We find that for...

We use linked employer-employee data from Italy to explore the relationship between exports and wages. Our empirical strategy exploits the 1992 devaluation of the Italian Lira, which represented a large and unforeseen shock to Italian firms’ incentives to export. The results indicate that the...
