This paper analyzes the dramatic rise in U.S. inflation since 2020, which we decompose into a rise in core inflation as measured by the weighted median inflation rate and deviations of headline inflation from core. We explain the rise in core with two factors, the tightening of the labor market...

Large price changes in industries affected by the COVID-19 pandemic have caused erratic fluctuations in the U.S. headline inflation rate. This paper compares alternative approaches to filtering out the transitory effects of these industry price changes and measuring the underlying or core level...

Why did the Federal Reserve let Lehman Brothers fail? Fed officials say they lacked the legal authority to rescue the firm, because it did not have adequate collateral to borrow the cash it needed. This paper summarizes a monograph that disputes officials' claims (Ball, 2016). These claims are...

This essay discusses rules for monetary policy in open economies. If policymakers seek to stabilize output and inflation, optimal rules in open economies differ considerably from optimal rules in closed economies. In open economies, stability is best achieved by targeting long-run inflation' a...

This paper examines the choice of a monetary-policy rule in a simple macroeconomic model. In a closed economy, the optimal policy is a output and inflation. In an open economy, the optimal rule changes in two ways. First, the policy instrument is a Conditions Index the exchange rate. Second, on...

This paper defines an efficient rule for monetary policy as one that minimizes a weighted sum of output variance and inflation variance. It derives several results about the efficiency of alternative rules in a simple macroeconomic model. First, efficient rules can be expressed as 'Taylor rules'...

This paper investigates the determinants of the "sacrifice ratio" for disinflation: the ratio of the loss in output to the fall in trend inflation. I develop a method for estimating the sacrifice ratio in individual disinflation episodes, and apply it to 65 episodes in moderate-inflation OECD...
