Abstract

This paper modifies the standard Hodrick Prescot Filter in order to reduce the problem of misleading predictive outcome when used with updated information. The modification allow for a more accurate estimation of output gap, as well as the introduction of confidence intervals that permit a better understanding of the uncertainty related to the estimation of the filter. Also improve the efficiency using a correction for autocorrelation in the errors of estimation.
