International Migration, Imperfect Information and Brain Drain

We consider a model of international migration where skills of workers are imperfectly observed by firms in the host country and where information asymmetries are more severe for immigrants than for natives. There are two stages. In the first one, workers in the South decide whether to move and pay the migration costs. These costs are assumed to be sunk. In the second stage, firms offer wages to the immigrant and native workers who are in the country. Because of imperfect information, firms statistically dicriminate high-skilled migrants by paying them at their expected productivity. The decision of whether to migrate or not depends on the proportion of high-skilled workers among the migrants. The migration game exhibits strategic complementarities, which, because of standard coordination problems, lead to multiple equilibria. We characterize them and examine how international migration affects the income of individuals in sending and receiving countries, and of migrants themselves. We also analyze under which conditions there is positive or negative self-selection of migrants.asymmetric information, screening, self-selection of migrants, skill-biased migration, wage differentials

Patent Pools and the Dynamic Incentives to R&D

Working paper du GATE 2007-03Patent pools are cooperative agreements between several patent owners to bundle the sale of their respective licenses. In this paper we analyze their consequences on the speed of the innovation process. We adopt an ex ante perspective and study the impact of possible pool formation on the incentives to innovate. Because participation in the creation of a pool acts as a bonus reward on R&D activity, we show that a firm's investment pattern is upward sloping over time before pool formation. The smaller the set of initial contributors, the higher this effect. A pool formation mechanism based on a proposal by the industry and acceptance/refusal by the competition authority may induce overinvestment in early innovations. It also leads a forward looking regulator to delay the clearance date of the pool. This may result in a pool size that is suboptimal from an ex ante viewpoint

Mutual Supervision in Preshipment Inspection Programs

Preshipment inspection programs are implemented in many developing countries to fight customs corruption. They consist in delegating the inspection of imports to a private firm that operates in the exporting country. To study those PSI programs, we develop a hierarchical agency model where the government authority can rely on two supervisors, namely the private inspection firm and the customs administration, to control importers' declarations. The government's optimal program is fully characterized. We devote some attention to the optimal inspection policy and its comparative statics properties. In particular, we identify the situations in which PSI programs are optimal. Our results highlight the fact that implementing PSI programs both to fight corruption and to modernize customs is inconsistent. We also discuss the optimal reconciliation policy, i.e. what to do in case of conflicting inspection reports by the private firm and the customs administration. In the optimal mechanism, mutual supervision between the private firm and the customs administration is used to provide adequate incentives to all parties.Preshipment inspection;Mutual supervision;corruption;Customs administration.
