Los ferrocarriles y su impacto sobre la economía colombiana

Recientemente en Colombia ha surgido el interes por explicar los acontecimientos de la historia economica del pais dentro del enfoque de la diometria. Sin embargo, el analisis del transporte y su influencia sobre el desarrolib economico nacional no ha recibido suficiente atencion. Este ensayo busca cubrir tal deficiencia; despues de todo, este es un tema central en el estudio de la historia economica de un pais. El trabajo proporciona una nueva base de datos que contribuye al estudio del desarrollo del transporte terrestre en Colombia. El aporte principal del estudio consiste en demostrar que los ferrocarriles no jugaron un papel fundamental en el desarrollo de la economia colombiana.

Depressions in the Colombian economic growth during the twentieth century: a Markov switching regime model

In this article, we modelled the Colombian long run economic growth (1925–2003) using a two-regime first order Markov switching model. We found evidence of nonlinearity in the annual rate of economic growth. The results show that changes between regimes are sudden and sporadic. The Colombian economy remains in the sustainable growth regime most of the time. The turning points from the Markov switching model capture very well the behaviour of real output through time. In fact, they identify the four main depressions of the century.

Long-run income and price elasticities of demand for Colombian nontraditional exports: a multivariate cointegration framework

A long run income and price elasticities of demand is estimated for Colombian nontraditional exports through a multivariate cointegration analysis. Based on the combination of cointegration and exogeneity concepts and the inclusion of the complete dynamic system, the paper shows the existence of a long-run relationship among nontraditional exports, relative price and foreign demand, and higher long-run elasticities than those provided by the long-run cointegration vector coefficients that are usually reported in the trade literature.
