This study examines in detail the experiences of three countries that have in recent years operated exchange rate systems of "crawling bands," similar in spirit to the target zones that the author has recommended in the past. Williamson compares the succcessful experiences of 3 countries that have operated crawling bands with 15 similar countries and concludes that the crawling band exchange-rate policy has been an important element in their success. The study includes a manual for managing crawling bands.

This paper examines inflation dynamics in Chile during the last peso depreciation episode 2013-15. The evidence is for substantial pass-through effects to inflation, given the large and persistent depreciation movement. Widespread indexation practices in non-traded goods markets are found to amplify the inflation response to the depreciation, while the role of wage indexation is less relevant to the inflation dynamics. Overall, inflation would have remained within the central bank’s target band absent the peso depreciation. The analysis also shows that tightening monetary policy in response to a depreciation shock can be costly in terms of output: the response of activity to rates is found to be strong, while the transmission from activity to inflation is found to be weak. Simulations under uncertainty about the extent of the pass-through also suggest that monetary policy can play a countercyclical role in the face of depreciation shocks at a moderate inflationary cost, as long as inflation expectations remain anchored.

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.

The Nobel Prize–winning economist explains how value is created, and how that affects everything from your paycheck to global markets. In this “lively, enlightening introduction to monetary history” (Kirkus Reviews), one of the leading figures of the Chicago school of economics that rejected the theories of John Maynard Keynes offers a journey through history to illustrate the importance of understanding monetary economics, and how monetary theory can ignite or deepen inflation. With anecdotes revealing the far-reaching consequences of seemingly minor events—for example, how two obscure Scottish chemists destroyed the presidential prospects of William Jennings Bryan, and how FDR’s domestic politics helped communism triumph in China—as well as plain-English explanations of what the monetary system in the United States means for your personal finances and for everyone from the small business owner on Main Street to the banker on Wall Street, Money Mischief is an enlightening read from the author of Capitalism and Freedom and Free to Choose, who was called “the most influential economist of the second half of the twentieth century” by the Economist.

Chile’s pension system came under close scrutiny in recent years. This paper takes stock of the adequacy of the system and highlights its challenges. Chile’s defined contribution system was quite influential when introduced, and was taken as an example by other countries. However, it is now delivering low replacement rates relative to OECD peers, as its parameters did not adapt over time to changing demographics and global returns, while informality persists in the labor market. In the absence of reforms, the system’s inability to deliver adequate outcomes for a large share of participants will continue to magnify, as demographic trends and low global interest rates will continue to reduce replacement rates. In addition, recent legislation allowing for pension savings withdrawals to counter the effects from the COVID-19 pandemic, is projected to further reduce replacement rates and increase fiscal costs. A substantial improvement in replacement rates is feasible, via a reform that raises contribution rates and the retirement age, coupled with policies that increases workers’ contribution density.
