Output-Inflation Trade-offs and the Optimal Inflation Rate

Takushi Kurozumi () and Willem Van Zandweghe ()

No 202020, Working Papers from Federal Reserve Bank of Cleveland

Abstract: In staggered price models, a non-CES aggregator of differentiated goods generates empirically plausible short- and long-run trade-offs between output and inflation: lower trend inflation flattens the Phillips curve and decreases steady-state output by increasing markups. We show that the aggregator reduces both the steady-state welfare cost of higher trend inflation and the inflation-related weight in a model-based welfare function for higher trend inflation. Consequently, optimal trend inflation is moderately positive even without considering the zero lower bound on nominal interest rates. Moreover, the welfare difference between 2 percent and 4 percent inflation targets is much smaller than in the CES aggregator case.
