Alternative Nominal Anchors: a Welfare Comparison

摘要

This paper compares the performances of three alternative nominal anchors, i.e., price inflation, nominal income growth, and money growth in an estimated monetary business cycle model. The representative households lifetime utility is used as a natural welfare metric, and the welfare e.ects of the non-linear dynamics are captured by a quadratic approximate solution method. Strict inflation targeting is a feasible and desirable choice only when the economy has to run high rates of long-run inflation. When the long-run inflation rate is close to zero, strict targeting of the other two anchors yields comparably higher welfare level than a feasible inflation targeting, since the e.ciency gains from lower long-run inflation and nominal interest rates outweigh the welfare e.ects of short-run inflation stabilization.
