Evidence of smooth transition autoregressive (STAR) representations is found in two, out of three, time series of different measures of annual inflation in Colombia during this decade for monthly data. The STAR-type nonlinearities are asymmetric for inflation computed as the variation of CPI...

En este documento se estima un modelo econométrico que descompone la serie de inflación trimestral anualizada entre un componente transitorio y otro permanente, este último inducido probablemente por las variaciones en la meta del Banco Central. Se concluye que la persistencia inflacionaria...

En este documento se evalúan las diferentes formas de medición de la persistencia estadística y los distintos factores estructurales que podrían explicarla. Se presenta una medición de la persistencia estadística de la inflación y de la brecha de inflación en Colombia para el período...

In the context of financial crises influenced by the development and burst of housing price bubbles, the detection of exuberant behaviors in the financial market and the implementation of early warning diagnosis tests are of vital importance. This paper applies the new method developed by...

This paper evaluates the fiscal sustainability hypothesis for eight Latin American countries, Argentina, Chile, Colombia, Ecuador, Panama, Peru, Paraguay and Uruguay, during the period 1960 - 2009. Using second generation cointegration panel data models, we test whether Government revenues and...

This paper investigates whether transforming the Consumer Price Index with a class of power transformations lead to an improvement of inflation forecasting accuracy. We use one of the prototypical models to forecast short run inflation which is known as the univariate time series ARIMA . This...

Typically, when forecasting inflation rates, there are a variety of individual models and a combination of several of these models. We implement a Bayesian shrinkage combination methodology to include information that is not captured by the individual models using expert forecasts as prior...

En este trabajo se analiza empíricamente la sostenibilidad fiscal en Colombia a través de las técnicas de cointegración. En particular, usando los ingresos tributarios y los gastos primarios del gobierno nacional central para el período 1990Q1 a 2008Q4 (datos reales y ajustados por el ciclo...

En este documento se establecen algunos hechos estilizados acerca del comportamiento de los precios regulados en Colombia. Se analiza el grado de rigidez de los precios en diferentes categorías de productos, con un énfasis particular en los precios regulados. En el documento se establece que...

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....
