PERI's research on finance, jobs and macroeconomics looks at financial institutions, markets, macroeconomic activity, and policy, and considers how these affect employment, inequality, economic instability and living standards in the U.S. and globally. Our focus is on advancing policies that will promote financial stability, full employment, and improvements in living standards for working people and the poor, and facilitate the transition to an environmentally sustainable economy.

How U.S. Labor and Capital Experienced the 2007-2008 Financial Crisis

January 2014 -- Mathieu Dufour and Ozgur Orhangazi examine whether the 2007 – 08 financial crisis in the U.S. hit the working class and poor disproportionately, in a pattern similar to that typically experienced by developing countries after financial crises. They find that while the burden of the crisis did fall disproportionately on labor and low-income segments of society, as typically happens in developing countries, the U.S. government did not experience the kinds of policymaking constraints that typically impose huge burdens on crisis-ridden developing countries.

PERI Economists Named to Foreign Policy Magazine’s 100 Leading Global Thinkers of 2013

December 2013 -- PERI Co-Director Robert Pollin, Economics Department Chair Michael Ash, and Economics graduate student Thomas Herndon were named the the "Challengers" category of Foreign Policy Magazine's 100 Leading Global Thinkers of 2013. This was due to their research identifying a series of serious errors in a highly influential study by Carmen Reinhart and Kenneth Rogoff that had been used as a major justification for austerity policies around the globe.

Public Debt, GDP Growth and Austerity

January 2014 -- In this revised paper published in the Cambridge Journal of Economics, Herndon, Ash and Pollin (HAP) replicate Reinhart and Rogoff (RR) and find that selective exclusion of available data, coding errors, and inappropriate weighting of summary statistics lead to serious miscalculations that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies. Over 1946 – 2009, countries with public debt/GDP ratios above 90 percent averaged 2.2 percent real GDP growth, not −0.1 percent, as RR reported. RR’s results for median GDP growth rates for the 1946 – 2009 period, and mean and median GDP growth figures over 1790 – 2009 are all distorted by similar methodological errors. HAP’s overall evidence refutes RR’s claim that public debt/GDP ratios above 90 percent consistently reduce a country’s GDP growth. In a separate supplemental paper, Pollin responds to charges by RR and others regarding HAP’s professional conduct, political biases and related issues as well as the significance of their findings for economic policy. Pollin summarizes the state of the debate in a separate blog for Oxford University Press.

Revisiting Theories of Long Economic Waves

December 2013 -- After the global financial meltdown in 2008, there has been renewed interest in theories of long economic waves that can explain long periods of expansion ending in recession. Lucas Bernard, Aleksander V. Gervorkyan, Thomas I. Palley, and Willi Semmler explore several long wave theories including Kondratieff’s theory of cycles in production and relative prices; Kuznets; theory of cycles arising from infrastructure investments; Schumpeter’s theory of cycles due to waves of technological innovation; Goodwin’s theory of cyclical growth based on employment and wage share dynamics; Keynes-Kaldor-Kalecki demand and investment-oriented theories of cycles; and Misky’s financial instability hypothesis.

Lessons from the Past for Rebuilding Financial Systems

August 2013 -- The financial crisis has called into question previously dominant neoliberal approach to macroeconomic and financial policy. Unfortunately, these lessons are being learned in an uneven manner – and in some important circles, not at all.

In this article for the Review of Keynesian Economics, Gerald Epstein surveys the recent history of developmental finance and central banking. He finds that central banks and related institutions have often played predominantly developmental roles, and that neoliberal approaches are more the exception than the rule. He proposes that the way out of the crisis is to build on current experiments in developmentally friendly policies, rather than abandoning them at the first opportunity.

Reassessing Debt-to-GDP Ratios: Critiquing Reinhart and Rogoff

April 2013 -- Thomas Herndon, Michael Ash and Robert Pollin examine Reinhart and Rogoff’s research on the relationship between public debt and GDP growth for advanced economies in the post World War II period. Reinhart and Rogoff argue that the rate of economic growth for these countries has consistently declined precipitously once the level of government debt exceeds 90 percent of the country’s GDP. In recent years, Reinhart and Rogoff’s results have been highly influential as support for austerity policies in both Europe and the United States. Herndon, Ash and Pollin find that a series of data errors and unsupportable statistical techniques led to an inaccurate representation of the actual relationship between public debt levels and GDP growth. They  find that when properly calculated, average GDP growth for advanced economies at public debt-to-GDP ratios over 90 percent is not dramatically different than when debt-to-GDP ratios are lower.

How Large Should the U.S. Financial Sector Really Be?

March 2013 -- In the aftermath of the financial crisis, many observers have concluded that the U.S. financial system has grown to excessive size relative to the economy’s non-financial sectors. Gerald Epstein and James Crotty explore ways to conceptualize the U.S. financial sector’s appropriate size and quality. They then look at the efficiency of the financial sector in financing real economic activity and the social purpose of financial innovation. They conclude from this preliminary research that “the financial sector may need to be only one-half to one-quarter as large as it is currently to serve the existing needs of the real sector.”

Theory and Policy for Preventing the Next Financial Crisis

February 2013 -- The crisis that began in 2007-2008 forcefully reminds us that financial instability is endemic to capitalist economies that lack dynamically changing financial regulations to keep the forces of leverage and credit within sustainable bounds. Nonetheless, today’s mainstream economists remain intractably opposed to such measures. In The Handbook of the Political Economy of Financial Crises, edited by Martin Wolfson and Gerald Epstein, an international group of experts describes the theoretical, institutional, and historical factors that can help us understand the forces behind financial crises and the strengths and weaknesses of theoretical perspectives and policy approaches that have tried to control these financial tsunamis.

Escaping the Liquidity Trap

June 2012 -- After the onset of the Great Recession, commercial banks in the U.S. began accumulating huge cash reserves at the Federal Reserve — $1.6 trillion by mid-2011. This was a result of the Fed pushing the federal funds rate to near zero in 2008, and holding it there through 2011 and beyond. Over this same period, non-corporate businesses obtained zero net credit. Under such circumstances, conventional central bank operations are greatly weakened as a policy tool. Robert Pollin considers policies for escaping this trap: raising the inflation target, depreciating the currency, targeting long-term interest rates, taxing excess reserves, and expanding federal loan guarantees for smaller businesses.

Taxing Wall Street: How to Design an Effective Transaction Tax

May 2012 -- As we continue to suffer the consequences of the global financial crash, a tax on financial market transactions has been gaining support as a way to bring some measure of control over speculative financial practices. The movement to establish a tax in the U.S. has been energized by the National Nurses Union under the theme “Heal America, Tax Wall Street.” In this "Economic Prospects" column for New Labor Forum, Robert Pollin describes the mechanics of the tax, its international support, and how to set a rate that can have a real impact on excessive speculation and the nation’s economic health.

How Cutting the Pentagon's Budget Could Boost the Economy

May 2012 -- In this article in The Nation, Robert Pollin and Heidi Garrett-Peltier look at the military's record as a jobs engine, and as a source of technological innovation, and recommend that to achieve both of these objectives optimally, the federal government is best off shifting its resources to other investments.
