This paper asks how well Okun’s Law fits short-run unemployment movements in the United States since 1948 and in twenty advanced economies since 1980. We find that Okun’s Law isa strong and stable relationship in most countries, one that did not change substantiallyduring the Great Recession. Accounts of breakdowns in the Law, such as the emergence of“jobless recoveries,” are flawed. We also find that the coefficient in the relationship—the effect of a one percent change in output on the unemployment rate—varies substantially across countries. This variation is partly explained by idiosyncratic features of national labormarkets, but it is not related to differences in employment protection legislation.

Originally published in 1975, Equality and Efficiency: The Big Tradeoff is a very personal work from one of the most important macroeconomists of the last hundred years. And this new edition includes "Further Thoughts on Equality and Efficiency," a paper published by the author two years later. In classrooms Arthur M. Okun may be best remembered for Okun's Law, but his lasting legacy is the respect and admiration he earned from economists, practitioners, and policymakers. Equality and Efficiency is the perfect embodiment of that legacy, valued both by professional economists and those readers with a keen interest in social policy. To his fellow economists, Okun presents messages, in the form of additional comments and select citations, in his footnotes. To all readers, Okun presents an engaging dual theme: the market needs a place, and the market needs to be kept in its place. As Okun puts it: Institutions in a capitalist democracy prod us to get ahead of our neighbors economically after telling us to stay in line socially. This double standard professes and pursues an egalitarian political and social system while simultaneously generating gaping disparities in economic well-being. Today, Okun's dual theme feels incredibly prescient as we grapple with the hot-button topic of income inequality. In his foreword, Lawrence H. Summers declares: On what one might think of as questions of "economic philosophy," I doubt that Okun has been improved on in the subsequent interval. His discussion of how societies rely on rights as well as markets should be required reading for all young economists who are enamored with market solutions to all problems. With a new foreword by Lawrence H. Summers

The negative and stable relationship between an economy’s aggregate demand conditions and overall unemployment is well-documented. We show that there is a large degree of heterogeneity in the cyclical sensitivities of unemployment across worker and economy groups. First, unemployment is more than twice as sensitive to aggregate demand in advanced as in emerging market and developing economies. Second, youth’s unemployment is twice as sensitive as that of adults’. Third, women’s unemployment is significantly less sensitive to demand than men’s in advanced economies. These findings point to the highly unequal impacts of the business cycle across worker and economy groups.

From the beginning of 2003 through the first quarter of 2006, real gross domestic product in the U.S. grew at an average annual rate of 3.4% As expected, unemployment during the period fell. Over the course of the next year, average growth slowed to less than half its earlier rate -- but unemployment continued to drift downward. This situation presented a puzzle, who expected the unemployment rate to increase as the economy slowed. This negative correlation between GDP growth & unemployment has been named ¿Okun¿s law.¿ This article considers the usefulness of Okun¿s law for policymakers & economists. Okun¿s relationship can be useful as a forecasting tool -- provided that one takes its instability into account. Charts & tables.

We find that Okun's Law is a strong and stable relationship in most countries, one that did not change substantially during the Great Recession. Accounts of breakdowns in the Law, such as the emergence of "jobless recoveries," are flawed. We also find that the coefficient in the relationship - the effect of a one percent change in output on the unemployment rate - varies substantially across countries. This variation is partly explained by idiosyncratic features of national labor markets, but it is not related to differences in employment protection legislation.
