The objective of this paper was to explain the greater or lesser growth rate of total factor productivity, TFP, in the main East Asian and Latin American economies between 1960 and 2015. We found econometric evidence favorable to this hypothesis: the increase in public consumption expenditures, given the evolution of other factors, reduces the TFP. Other results of the econometric exercise, those that are related to hypothetical positive effects of public investment and imports on TFP were not as robust or as reliable as we would have expected.
Este artículo se enmarca en el análisis del comportamiento de la tasa de cambio nominal bajo el régimen de bandas que se observó en Colombia entre el 24 de enero de 1994 y el 24 de septiembre de 1999. El propósito principal es caracterizar los regímenes que registró la tasa de cambio nominal en este período (devaluación o revaluación) y la ley que gobernó su transición, a través de un sistema de cadenas de Markov. Concretamente, se utiliza el modelo de tendencias estocásticas segmentadas desarrollado en 1990 por James D. Hamilton y se modela la tasa de cambio semanal como si fuera generada por uno de los regímenes señalados.Palabras clave: banda cambiaria, realineamientos, política cambiaria, modelo de tendencias estocásticas segmentadas.
