Leading Indicator of Inflation

Serie Documentos de Trabajo , Gerencia de Investigaciones Económicas, Banco Central de Venezuela
We construct an anticiped indicator of the prices cyclical movement, measured by the Consumer Price Index (CPI). Using a spectral smoothing method, we built reference series for inflation and the other variables used to compute the indicator. The weights used to aggregate the variables were derived by principal componentes analysis (PCA). In order to obtain cualitative measures of inflation, in addition to trend ones, we take the indicator as an exogenous variable in a transfer function model.
