This paper develops a new price index (DIPI) and discusses its properties and its dynamics. By allowing for habit formation and inertia, our proposed index extends previous dynamic indexes that only have a forward looking component, thus providing a more reliable indicator for the design of policy measures. We calculate the DIPI for a sample of goods for the US and illustrate its effectiveness in tracking business cycle. DIPI identifies a higher number of deflation periods and was on average lower than the CPI. Our results are in line with the recommendations of the Boskin Commission, which argued that CPI overestimates inflation.
