The historical behavior of interest rates and growth rates in U.S. data suggests that the government can, with a high probability, run temporary budget deficits and then roll over the resulting government debt forever. The purpose of this paper is to document this finding and to examine its...

From 2000 to 2003, when Ben Bernanke was a professor and then a Fed Governor, he wrote extensively about monetary policy at the zero bound on interest rates. He advocated aggressive stimulus policies, such as a money-financed tax cut and an inflation target of 3-4%. Yet, since U.S. interest...

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...

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 compares the performance of economies with different monetary regimes during the last quarter century. The conclusions include: (1) There is little evidence that inflation targeting affects performance in advanced economies, but some evidence of benefits in emerging economies; (2)...

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 seeks to understand the behavior of Greenspan's Federal Reserve in the late 1990s. Some authors suggest that the Fed followed a simple 'Taylor rule,' while others argue that it deviated from such a rule because it recognized that the 'New Economy' permitted an easing of policy. We...

This paper presents a model of dynamically consistent monetary policy that explains changes in inflation over time. In the model -- as in the postwar United States -- adverse supply shocks trigger persistent increases in inflation, and disinflation occurs when a tough policymaker creates a...

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 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...
