GROWTH AND WAGE INEQUALITY IN A SCALE-INDEPENDENT MODEL WITH R&D AND HUMAN-CAPITAL ACCUMULATION

We present a dynamic, non-scale general equilibrium model with two human-capital types where Schumpeterian R&D and human-capital accumulation are the engines of growth and wage inequality. In particular, wage inequality is encouraged by relative changes in supply and demand of both human-capital types. Relative supply restricts employed human-capital levels. Relative demand is instantly affected by a new general-purpose technology and, as in the skill-biased technological change literature, by technological-knowledge bias. By considering substitutability between technologies and complementarity between inputs, the bias is driven by the price channel (not by the market-size channel) and is affected by human-capital accumulation.
