Low Inflation Bends the Phillips Curve around the World
This paper finds strong support for a Phillips curve that becomes nonlinear when inflation is “low”—which our baseline model defines as less than 3 percent. The nonlinear curve is steep when output is above potential (slack is negative) but flat when output is below potential (slack is positive) so that further increases in economic slack have little effect on inflation. This finding is consistent with evidence of downward nominal wage and price rigidity. When inflation is high, the Phillips curve is linear and relatively steep. These results are robust to placing the threshold between the high and low inflation regimes at 2, 3, or 4 percent inflation or for a threshold based on country-specific medians of inflation. In this nonlinear model, international factors play a large role in explaining headline inflation (albeit less so for core inflation), a role that has been increasing since the global financial crisis. These results provide evidence of channels which could boost inflation in the future, even if they were dormant before the Covid pandemic.

WHAT HAVE WE LEARNED ABOUT CENTRAL BANK BALANCE SHEETS AND MONETARY POLICY?
In the aftermath of the Great Recession of 2008-09, central banks conducted large-scale purchases of long-term bonds and other unconventional financial assets to stimulate economic recoveries and raise inflation toward its targeted level. Dire predictions of runaway inflation and financial distortions did not come to pass. But recovery proved much slower than had been expected. This article argues that the main lesson is that central banks need to use their powers more aggressively if confronted with a similar situation in the future. Planning now can help central banks to be more prepared later. It is also a good time to make sure central banks have all the tools they need to confront the zero bound on nominal interest rates.

Flexible exchange rates for a stable world economy
Volatile exchange rates and how to manage them are a contentious topic whenever economic policymakers gather in international meetings. This book examines the broad parameters of exchange rate policy in light of both high-powered theory and real-world experience. What are the costs and benefits of flexible versus fixed exchange rates? How much of a role should the exchange rate play in monetary policy? Why don't volatile exchange rates destabilize inflation and output? The principal finding of this book is that using monetary policy to fight exchange rate volatility, including through the adoption of a fixed exchange rate regime, leads to greater volatility of employment, output, and inflation. In other words, the \"cure\" for exchange rate volatility is worse than the disease. This finding is demonstrated in economic models, in historical case studies, and in statistical analysis of the data. The book devotes considerable attention to understanding the reasons why volatile exchange rates do not destabilize inflation and output. The book concludes that many countries would benefit from allowing greater flexibility of their exchange rates in order to target monetary policy at stabilization of their domestic economies. Few, if any, countries would benefit from a move in the opposite direction.

Direct and Spillover Effects of Unconventional Monetary and Exchange Rate Policies
This paper explores the direct effects and spillovers of unconventional monetary and exchange rate policies. We find that official purchases of foreign assets have a large positive effect on a country’s current account that diminishes considerably as capital mobility rises. There is an important additional effect through the lagged stock of official assets. Official purchases of domestic assets, or quantitative easing (QE), appear to have no significant effect on a country’s current account when capital mobility is high, but there is a modest positive impact when capital mobility is low. The effects of purchases of foreign assets spill over to other countries in proportion to their degree of international financial integration. We also find that increases in US bond yields are associated with increases in foreign bond yields and in stock prices, as well as with depreciations of foreign currencies, but that all of these effects are smaller on days of US unconventional monetary policy announcements. We develop a theoretical model that is broadly consistent with our empirical results and that highlights the potential usefulness of domestic unconventional policies as responses to the effects of foreign policies of a similar type.

Monetary policy and exchange rate pass-through
The pass‐through of exchange rate changes into domestic inflation appears to have declined in many countries since the 1980s. We develop a theoretical model that attributes the change in the rate of pass‐through to increased emphasis on inflation stabilization by many central banks. This hypothesis is tested on 20 industrial countries between 1971 and 2003. We find widespread evidence of a robust and statistically significant link between estimated rates of pass‐through and inflation variability. We also find evidence that observed monetary policy behaviour may be a factor in the declining rate of pass‐through. Published in 2004 by John Wiley & Sons, Ltd.

The global outlook for government debt over the next 25 years : implications for the economy and public policy
This study addresses a fundamentally new feature of the contemporary world economy: the simultaneous buildup of very large public deficits and debt positions in virtually all of the advanced high-income countries. The recent global financial crisis sharply accelerated this fiscal deterioration, but it was already well underway in some countries, including the United States, where demographic prospects had posed extremely worrisome trajectories for a number of years. The book has three basic objectives. First, it projects the global fiscal outlook to 2035. Second, it asks whether the combination of deficits and debt in a large number of countries at the same time produces an impact on the world economy that is qualitatively different from the more traditional emergence of such problems in one or a few countries in any given period. Third, it analyzes the effects of the fiscal prospects on key economic variables including global interest rates and growth rates. The analysis finds that the current public debt profiles in most advanced economies will grow to dangerous and unsustainable levels over the next couple of decades unless major changes are made in projected spending and revenue levels. The authors conclude that the United States and Japan, in particular, need to start planning now for significant future budget cuts to minimize the risk of a crisis. Acting soon enables the adjustment to be phased in over an extended period, which cushions the inevitable adjustment costs, while avoiding the potentially enormous pressures that could be levied by markets if correction is delayed too long.
