This paper examines policy responses to exchange-rate movements in a simple model of an open economy. The optimal response of monetary policy to an exchange-rate change depends on the source of the change: on whether the underlying shock is a shift in capital flows, manufactured exports, or...

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...

The paper considers the macroeconomic transmission of demand and supply shocks in an open economy under alternative assumptions on whether the zero interest floor (ZIF) is binding. It uses a two-country general-equilibrium simulation model calibrated to the Japanese economy vis-a-vis the rest of...

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 paper examines the predictive power of shifts in monetary policy, as measured by changes in the federal funds rate, for output, inflation, and survey expectations of these variables. We find that policy shifts have larger effects on actual output than on expected output, suggesting that...

This paper investigates the effects of wage indexation on the time-consistent level of inflation. Departing from previous work on time-consistent policy, we study a structural model of the economy. Indexation reduces the cost of inflation, which is inflationary, and steepens the Phillips curve,...

This paper is a contribution to the analysis of optimal monetary policy. It begins with a critical assessment of the existing literature, arguing that most work is based on implausible models of inflation-output dynamics. It then suggests that this problem may be solved with some recent...

Rigidities in real prices are not sufficient to create rigidities in nominal prices and real effects of nominal shocks. And, by themselves, small frictions in nominal adjustment, such as costs of changing prices, create only small non-neutralities. But this paper shows that substantial nominal...

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...
