Many countries pursue an immigration policy that is targeted at attracting high skilled workers. Borjas (1995) has shown that assuming perfect labor markets immigration leads to a welfare gain for the native population, the so-called immigration surplus. Thus, as the labor market for high...

Recent theoretical literature studies how labor market reforms in one country can affect labor market outcomes in other countries, thereby rationalizing widely-held policy beliefs and empirical evidence. But what is the quantitative relevance of such spillover effects? This paper combines two...

Exhaustion of a natural resource stock may be a rational choice for an individual and/or a community, even if a sustainable use for the resource is feasible and the resource users are farsighted and well informed on the ecosystem. We identify conditions under which it is optimal not to sustain...

We consider non-cooperative environments in which two players have the power to commit but cannot sign binding agreements. We show that by committing to a set of actions rather than to a single action, players can implement a wide range of action profiles. We give a complete characterization of...

The purpose of this article is to analyze how the presence of a competitive fringe, composed by price taker firms, can affect the sustainability of collusive equilibria. Our starting point is that there exists a diffused misunderstanding about its strategical role as collusive minus factor. We...

In this article we apply and extend the model elaborated by Acemoglu and Verdier in their seminal paper (2000), to examine how the economy represented in their theoretical framework responds to an exogenous change in the agent's incentive. In particular, we focus on the consequences of a famous...

Internet, mp3 files, peer-to-peer software and digital technologies for copying have radically modified the music sector. In this paper I present a theoretical model, that investigates the consequences of the appearance of a pirate low quality good (typically a mp3 file) in the music market. In...

This paper studies energy bias in technical change. For this purpose, we develop a computable general equilibrium model that builds on endogenous growth models. The model explicitly captures links between energy, the rate and direction of technical change, and the economy. We derive the...

We study how restricting CO2 emissions affects resource prices and depletion over time. We use a Hotelling-style model with two non-renewable fossil fuels that differ in their carbon content (e.g. coal and natural gas) and in addition are imperfect substitutes in final good production. We show...
