We consider a model of factor saving innovations and study the effects of exogenous changes in labor supply. In a biased innovations setting, as economies accumulate capital, labor becomes relatively scarce and expensive. As a consequence, incentives for labor saving and capital using...

We propose a one-good model where technological change is factor saving andcostly. We consider a production function with two reproducible factors: physical capital and human capital, and one not reproducible factor. The main predictions of the model are the following: (a) The elasticity of...

We present an endogenous growth model where innovation are factor saving. Tecnologies can be changed paying a cost so, tecnological change take place only if the benefits are larger than the cost. Since the gains derived from factor saving innovations depend on factor abundance, biased...
