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...

The common assumptions that labor income share does not change over time or across countries and that factor income shares are equal to the elasticity of output with respect to factors have had important implications for economic theory. However, there are various theoretical reasons why the...

In general, empirical studies on growth consider, at most, three factors, physical capital, labor and human capital. Land, however, is also a production factor for many activities. In this study, we make growth regressions considering land as factor. We also propose an explanation for why labor...

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...

The relative stability of aggregate labor share constitutes one of the great macroeconomic ratios. However, relative stability at the aggregate level masks the unbalanced nature of sectoral labor shares. We present a two-sector (manufacturing and services) model with induced innovation that can...

Spanish Abstract: Las negociaciones de paz emprendidas por el Gobierno Nacional y las Fuerzas Armadas Revolucionarias de Colombia –Ejército del Pueblo (FARC-EP), coincidieron con un repunte de las hectáreas sembradas con coca en el país. El repunte en el área cultivada puede estar...

Spanish Abstract: Con la salida de las FARC, el grupo guerrillero que monopolizó el mercado de la cocaína y el mayor causante de violencia en el país, se vuelve relevante estudiar el comportamiento del mercado de las drogas y los cambios en las dinámicas de violencia. El propósito de este...

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...
