Desigualdade intragrupos educacionais e crescimento

There is important evidence of a recent upsurge of so-called residual inequality, i.e. wage inequality that cannot be explained by workers? observable attributes, such as schooling. The main purpose of this article is to review the intuitions and results of some of the main theoretical models that have been proposed in order to deal with this phenomenon. In these models, the emergence of ?residual inequality? is associated with growth processes centered in technological change. Three groups of explanation are identified. The first group emphasizes the skill bias of recent technical change as a major factor; the second one is based on the stochastic processes that major technical changes set forth; the third one relates within group inequality to technological progress characterized by Schumpeterian ?creative destruction? and a dual market labor. As a consequence, a new light is also cast on between-group inequality.
