Estudio del fenómeno de inflación importada vía precios del petróleo y su aplicación al caso colombiano mediante el uso de modelos VAR para el periodo 2000-2009

The objective of this article is to examine whether the oil price variable fueled a phenomenon of imported inflation in Colombia for the period from January 2000 to July 2009. The estimation strategy is based on the VAR (Vector Autoregression) model taking into account WTI oil prices and the CPI (Consumer Price Index). This model provided evidence that shows that Colombia may be a case of imported inflation, signaling that inflation is not an endogenous process, but rather a process under the influence of external variables.
