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 several theoretical reasons for why the...

In this study, we propose an explanation for why labor and capital shares do not seem to have a trend: an increasing trend in physical capital share is compensated by a decreasing trend in land share. Similarly, an increasing trend in human capital share is compensated by a decreasing trend in...

La economía colombiana ha venido experimentando un fuerte proceso de apreciación real en lo que va corrido de los noventas. En efecto, tomando un índice del tipo de cambio real definido como la relación entre el precio de los bienes transables y el precio de los bienes no transables se...

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 la-bor saving and capital using...

Measuring labor's share of an economy's aggregate income seems straightforward,at least in principle. Count up wage and salary income, along with the value of benefitsprovided to employees, and divide it by total income. However, one fundamentalconcept of labor's share in macroeconomic theory is...

We formulate and solve a model of factor saving technological improvement considering three factors of production: labor, capital and energy. The productive activities have three main characteristics: …first, in order to use capital goods fi…rms need energy; second, there are two sources of...

Este trabajo aporta dos elementos básicos para el análisis del crecimiento económico en Colombia: En primerlugar, para el cálculo de la participación de los factores en el producto, se separa el ingreso de capital físico del ingreso de capital natural y el ingreso del trabajo básico del...

Recent evidence show that factor shares, if properly measured, are far from constant.Moreover, the shares of natural resources and raw labor seem to be negativelycorrelated with income per capita while the share of human and physical capital ispositively correlated with income per capita. Now,...

We present an endogenous growth model where innovations are factor-saving and model the choice of technologies in an Overlapping Generations Model where any technology can be adopted paying a cost. Markets are competitive and marginal productivity of factors determines factor prices; therefore,...

We consider a decentralized version of the neoclassical growth model where labor share is chosen by workers to maximize their long run (permanent) wages. In this framework, if the labor share increases relative to the competitive share, workers capture a larger share of a smaller total income in...
