Illegal immigration is a major policy challenge in Europe, in particular in countries on the external border of the EU such as Italy or Spain. However, there are likely to be important eects on the rest of the EU, too, depending on the policies against illegal immigration in border countries....

Maskin and Tirole have defined payoff-relevant states in discrete time dynamic games with observable actions in terms of a partition of the set of histories. Their proof that this partition is unique cannot be applied, when action spaces are infinite or when players are unable to condition on...

This paper studies the implications of asymmetric fiscal stabilization policy for the budget deficit. In our model, the government is more concerned about downturns than upturns in economic activity and therefore conducts fiscal stabilization policy in a precautionary way. We show that this type...

Recent empirical evidence seems to show that temporary migration is a widespread phenomenon, especially among highly skilled workers who return to their countries of origin when these begin to grow. This paper develops a simple, tractable overlapping generations model that provides a rationale...

We develop a model that incorporates salient features of growth in modern economies. We combine the expanding-variety growth model through horizontal innovations with a hierarchy of basic and applied research. The former extends the knowledge base, while the latter commercializes it. Two-way...

This paper analyzes the question of whether traders learn to coordinate on a trading institution that guarantees market clearing, or whether other market institutions can survive in the long run. While we find that the market clearing institution is indeed always stable under a general class of...

Weak convergence results for sample averages of nonlinear functions of (discrete-time) stochastic processes satisfying a functional central limit theorem (e.g., integrated processes) are given. These results substantially extend recent work by Park and Phillips (1999) and de Jong (2001), in that...
