Increasingly, a small number of lowwage countries such as China, India and Mexico are involved in incremental innovation. That is, they are responsible for resolving productionline bugs and suggesting product improvements. We provide evidence of this new phenomenon and develop a model in which...

This paper presents firm level evidence on the dynamics of nonmanual 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 o¤setting disaggregate forces. First, while technical...
