We study the effect “globalization” on wage inequality. Our “global” economy resembles Rosen (1981) “Superstars” economy, where a) innovations in production and communication technologies enable suppliers to reach a larger mass of consumers and to improve the (perceived) quality of...

I briefly review the empirical evidence in the trade and wages debate, which overwhelmingly rejects the Heckscher-Ohlin explanation for recent increases in OECD skill premia. I then argue that the same evidence is also difficult to reconcile in general equilibrium with the view that exogenous...

I argue that increased foreign competition can affect technical choice and skill differentials even when actual imports do not rise significantly. I present a model of General Oligopolistic Equilibrium ("GOLE") in which a reduction in import barriers (whether technological or policy-imposed)...

This Paper presents firm level evidence on the dynamics of non-manual wage premia and employment shares in Italian manufacturing during the nineties. We find that the relative stability of aggregate wage premia and employment shares hides offsetting disaggregate forces. First, while technical...

We propose a theory that explains why international trade can widen a wage gap between top income earners and others and cause job polarization. In the basic model, we consider two symmetric countries in which individuals with different abilities work either as knowledge workers, who develop...

This paper explores the impact of trade on the relative returns to skill in the presence of non-homothetic preferences. In a general equilibrium model of trade in differentiated products, it is shown that, if consumers react to a rise in real income by increasing their demands of the relatively...

A growing empirical literature attributes much of the productivity advantages of large, "superstar" firms to their adoption of best practice management techniques that allow them to better identify and use talented workers. The reasons for the incomplete adoption of these "structured management...
