e investigate the role of constituents’ preferences in shaping the voting behavior of elected representatives on immigration and trade policy. Using a novel dataset spanning the period 1986-2004, in which we match individual opinion surveys with congressmen roll call votes, we find that...

Using census data for 1996, 2001 and 2007 the authors study the labor market effect of immigration in South Africa. In this period the share of foreign born over the total population has grown by almost fifty percent, and both the characteristics and geographical distribution of immigrants show...

A class of non cooperative games characterized by a `congestion e ect' is studied, in which there exists a strong Nash equilibrium, and the set of Nash equilibria, the set of strong Nash equilibria and the set of strategy pro les maximizing the potential function coincide.The structure of the...

In congestion games, players use facilities from a common pool. The benefit that a player derives from using a facility depends, possibly among other things, on the number of users of this facility. The paper gives an easy alternative proof of the isomorphism between exact potential games and...
