La persistencia estadística de la inflación en Colombia

this document discusses the different structural factors which could contribute to inflation persistence, and evaluates alternative ways to measure it. using the "best" methodologies, it presents the evolution of persistence both for the level and the gap of inflation in colombia in 1990-2010 using a regime switching model and a kalman filter. the adoption of inflation targeting in 1999 produced an important reduction in mean and variance but has not significantly modified the persistence of inflation.
