We estimate a non-parametrical Capital Asset Pricing Model (CAPM) and find strong evidence rejecting the classical linear CAPM. Furthermore, we find inconsistent linear betas for a series of stocks in the Colombian stock exchange (BVC), supporting the hypothesis of a better and consistent...

Three methodologies of estimation of models with many predictors are implemented to forecast Colombian inflation. Two factor models, based on principal components, and partial least squares, as well as a Bayesian regression, known as Ridge regression are estimated. The methodologies are compared...

An application of Bayesian Model Averaging, BMA, is implemented to construct combined forecasts for the colombian inflation for the short and medium run. A model selection algorithm is applied over a set of linear models with a large dataset of potencial predictors using marginal as well as...

El objetivo de este documento es realizar una estimación de la distribución de pérdidas de las carteras comercial y de microcrédito mediante una aproximación no paramétrica. Se utilizó la metodología de bootstrapping para encontrar esta distribución de pérdidas como porcentaje del...

This paper contains the results of a non parametric multi-step ahead forecast for the monthly Colombian inflation, using Mean conditional Kernel estimation over inflation changes, with no inclusion of exogenous variables. The results are compared with those from an ARIMA and a nonlinear STAR....

Capital controls and intervention in the foreign exchange market are two controversial policy options that many countries have adopted in the past in order to influence the exchange rate and moderate capital flows. Colombia has a long record in the use of these policies with mixed results and...

Este documento evalúa el grado de transmisión de corto y largo plazo sobre la inflación de los bienes importados de un choque a la depreciación del peso colombiano cuando se controla por el ciclo económico. Encontramos que la transmisión es mayor cuando la perturbación ocurre en un...

Colombian monthly data covering the period from 1995:01 to 2002:11 and ECM, fixed and time-varying parameters and Kalman filter techniques are used in this paper to quantify the exchange rate pass-through effects on import prices within a sample of manufactured imports. Also, whether the foreign...

This paper examines the role of exchange rates in determining the short-and-long run trade balance behavior for Colombia. Conventional wisdom says that a nominal devaluation improves the trade balance. This conjecture is rooted in the Bickerdike-Robinson-Metzler(BRM) and Marshall-Lerner(ML)...

En este documento estimamos el grado de transmisión de corto y largo plazo sobre la inflación de los bienes importados de un choque a la tasa de devaluación nominal en presencia de asimetrías. Utilizamos una ecuación estándar de pass-through para modelos con competencia imperfecta, datos...
