In this document we use the Expectations Survey conducted monthly by the Central Bank of Colombia during the period of October 2003 – August 2012. We find that exchange rate revaluations were generally followed by expectations of further revaluation in the short run (1 month), but by...

As a natural extension to León and Vivas (2010) and León and Reveiz (2010) this paper briefly describes the Cholesky method for simulating Geometric Brownian Motion processes with long term dependence, also referred as Fractional Geometric Brownian Motion (FBM). Results show that this method...

This research studies the forecasting performance of conventional and more recent exchange rate models in Colombia. The purpose is to explain which have been the main exchange rate determinants under an Inflation Targeting regime and a completely floating exchange rate scheme. Compared to...

The adoption of a managed regime assumes that interventions are relatively successful. However, while some authors consider that foreign exchange interventions are ineffective, arguing that domestic and foreign assets are close substitutes, others advocate their use and maintain that their...

To date, there is still great controversy as to which exchange rate model should be used or which monetary channel should be considered, when measuring the effects of monetary policy. Since most of the literature relies on structural models to address identification problems, the validity of...

Se utiliza la metodología VAR estructural para evaluar el impacto conjunto de las intervenciones cambiarias y de la política monetaria convencional sobre la tasa de cambio, la tasa de interés y las demás variables del sistema. Se encuentra que las compras netas de divisas devalúan...

Se analizan los efectos de los movimientos de las tasas de intervención del Banco de la República en la estructura a plazo. La evidencia sugiere que, en frecuencia diaria, las reacciones son imperceptibles. Sin embargo, con datos en frecuencia semanal, la evidencia muestra un efecto...

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...

Se utiliza información de los mercados de Estados Unidos e Inglaterra para hacer estimaciones actuales de la capacidad que tienen la Reserva Federal y el Banco de Inglaterra de afectar las tasas de interés del mercado. Las estimaciones muestran que la reacciones son mucho menores que las...
