The authors propose a short run model for the monetary transmission mechanism in which the output gap is model as an unobserved variable. By estimating this model using maximum likelihood on a Kalman Filter, the authors find an estimate of the unobserved output gap as well as its estimation...

The purpose of this pape ris to analyze the relationship between trade and agglomeration in the case of cities located far from the coast. In a modified version of the Krugman and Elizondo model, trade should make industries move to the coast in order to reduce internal freight costs. However,...

En este artículo se propone una reflexión empírica: examinar los resultados de la estimación y la capacidad de previsión de diferentes versiones de una curva de Phillips lineal para Colombia. Se hace, igualmente, una selección de los mejores modelos. La estimación por mínimos cuadrados...
