Factor shares vary over time and across countries, so incorporating variable factor shares into growth and development accounting is both warranted and desirable. However, variable factor shares create an index number problem in analyses relying on our most commonly used production functions. We...

We present an endogenous growth model where innovations are factor saving and model the choice of technologies in an Overlapping Generations framework. Markets are competitive and factor prices are determined by marginal productivity of factors; therefore, the income share of reproducible...

Spanish Abstract: Los habitantes de calle son, en su mayoría, consumidores de sustancias psicoactivas y enfrentan riesgo de salud excepcionalmente altos; muchos de ellos son víctimas frecuentes de varios delitos y algunos cometen delitos de manera regular. En este orden de ideas, es...

Currently the FARC and the Colombian Government are negotiating a peace agreement in the city of Havana in Cuba. Although the results of these talks are uncertain and the final goal of the rebels is not observable, it is possible to analyze their strategy under different scenarios and associate...

Spanish Abstract: Este trabajo describe las relaciones entre el entorno institucional, la economía, la distribución del ingreso y la productividad en Colombia. En particular, existe un problema de diseño institucional que fomenta la informalidad, dificulta la inclusión, inhibe la...

Spanish Abstract: Este artículo presenta una aproximación teórica a la relación causal entre el precio de los recursos naturales y las trampas de pobreza para el caso de un país productor de minerales. Partiendo de un modelo de generaciones traslapadas donde las decisiones de ahorro,...

Spanish Abstract: En las últimas décadas se han tramitado 11 reformas a la legislación tributaria en Colombia. Los numerosos cambios a los que se ha enfrentado la legislación tributaria colombiana convierten al país en uno de los países con mayor variabilidad en las reglas tributarias. Con...

This paper presents an endogenous growth model where the aggregate 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, in...

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...

In general, empirical studies on economics rely on the assumption of constant capital share of income both at the aggregate level and at the sector level. However, there is no empirical evidence supporting the constancy of capital share at the sector level. In this paper, using Colombian data,...
