Increases in capital shares affect the marginal productivity of capital, stimulating capital accumulation. Can a decrease in labor shares reduce the supply of labor? We explore this question using a model of fertility inspired by Caldwell (1982) and Boldrin and Jones (2002). Individuals may...

We claim that the standard methodology to study the effects of the reallocation of factors on growth is not adequate in the presence of biased innovations. Labor-saving innovations increase output per worker and may decrease the marginal productivity of labor. Therefore, a reallocation of labor...

Variation in factor shares, extensively documented in recent years, implies that standard growth accounting exercises are plagued by measurement issues. First, the standard assumption of constant shares generates a bias in the estimation of the contribution of factors to economic growth. Second,...

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...
