We explore the relationship between union density and labor’s shares using panel data on 35 industries, spanning the entire US economy, for the years 1983 through 2005. For the full sample, a standard deviation increase in union density (membership or coverage rates) is associated with an...

The relative stability of aggregate labor's share constitutes one of the great macroeconomic ratios. However, changes in individual industry labor's shares are essentially statistically independent of one another, and the average values of industry labor's shares vary widely. We present a...

This note presents a simple extension of the seminal Romer (1990, Journal of Political Economy 98(2), 71â102) paper. Allowing for elasticity of substitution between labor and capital to be different from one (CES production function instead of CobbâDouglas), the following results are obtained....

We present an endogenous growth model where innovations are factor saving. Technologies can be changed paying a cost and technological change takes place only if the benefits are larger than the costs. Since the gains derived from factor saving innovations depend on factor abundance, biased...

This paper presents an endogenous growth model where the aggre- gate production function is a Leontief (1941) and long run growth is completely explained through biased technological change. Under this framework we get two results: (i) if the income share of reproducible factors is high enough,...

El objetivo de este trabajo es contribuir a identificar el efecto de las remesas que envían los emigrantes a sus comunidades de origen en México. Del mismo modo, se estudia el efecto que la participación de la mujer tiene en este proceso. La fuente de información es el Consejo Nacional de...

We present an Overlapping Generations Model with two final goods: tradable goods are produced with a standard Cobb-Douglas production function and non-tradable goods are produced with linear production function where the only factor is labor. We maintain the fundamental assumption of factor...

We try to explain why economic conflicts and illegal business often take place in poor countries. We use the concept of subsistence level of consumption (d) and assume a regular concave utility function for consumption levels higher than d. For consumption levels lower than d utility is constant...

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...

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...
