This paper contributes to the debate on the effects of trade versus technological change on wage differentials. We propose an explanation of the stylized facts which is based on interactions between openness and technological change because of labor market institutions and government...

Defensive innovations in developed countries can explain the empirical phenomenon that openness towards trade with less-developed countries does not necessarily induce a substantial increase in the wage differential and trade volumes. Building on step-by-step innovations as introduced by Aghion...

Capital deepening may affect the evolution of the wage differential between skilled and unskilled workers differently in countries with different labor market institutions. If labor market institutions raise the relative wage of unskilled workers in Germany, firms have incentives to invest...

We characterize optimal redistribution in a dynastic family model with human capital. We show how a government can improve the trade-off between equality and incentives by changing the amount of observable human capital. We provide an intuitive decomposition for the wedge between human-capital...

In this paper we investigate the importance of labor market institutions such as unemployment insurance, unions, firing regulation and minimum wages for the evolution of wage inequality across countries. We derive a simple log-linear equation of the wage differential as a function of the...

Both personal bankruptcy and redistributive taxes can insure households' consumption risk and both vary considerably across US states. We derive sufficient conditions under which more redistributive taxation makes bankruptcy exemptions less attractive both for the intratemporal insurance and for...
