We incorporate a variable elasticity of substitution production function into an overlapping generations model à la Diamond (1965). We show that a certain parameter in the production function is a source of biased technical change is a crucial determinant of the economy's growth dynamics. For...

This paper performs a nonlinear estimation of a normalized CES production function within a system of equations with a panel of Spanish regions for the period 1964-2013. It obtains an elasticity of substitution below one and identifies different rates of factor-augmenting technical progress. The...

We develop a model of directed technology adoption, frictional unemployment, and migration to examine the effects of a change in skill endowments on the wages, employment rates, and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution...
