The Growth of Finance

by Robin Greenwood and David S. Scharfstein

Abstract

The U.S. financial services industry grew from 4.9% of GDP in 1980 to 7.9% of GDP in 2007. A sizeable portion of the growth can be explained by rising asset management fees, which in turn were driven by increases in the valuation of tradable assets, particularly equity. Another important factor was growth in fees associated with an expansion in household credit, particularly for residential mortgages. This expansion was itself fueled by the development of non-bank credit intermediation (or "shadow banking"). Whether the growth of the financial sector has been socially beneficial depends on one's view of active asset management, the increase in household credit, and the growth of shadow banking. While recognizing some of the benefits of professional asset management, we are skeptical about the marginal value of active asset management. We then raise concerns about whether the potential benefits of increased access to household credit—the main output of the shadow banking system—are outweighed by the risks inherent in this new approach to credit delivery.

On the afternoon of Monday October 13, 2008, Hank Paulson Jr., the Secretary of the Treasury of the United States, walked into the large conference room across the hall from his office in the Treasury Department. Joining him were Federal Reserve Chairman Ben Bernanke, President of the Federal Reserve Bank of New York Timothy Geithner, Chair of the Federal Deposit Insurance Corporate Sheila Bair, and the Chief Executive Officers of nine of the largest banks in the United States. This distinguished group had been brought together by the most serious financial crisis since the Great Depression of the 1930s. Financial panic was pushing the U.S. and European financial systems to the brink of failure. Paulson hoped his meeting with the bank CEOs would be a turning point. U.S. financial markets were closed for Columbus Day, and Paulson was planning to announce the latest government actions to stabilize the financial system before markets reopened on Tuesday.

In February and March 2009, the U.S. economy was in the midst of a terrifying financial and economic crisis. Between the beginning of 2008 and early 2009, four of the 25 largest U.S. financial institutions had failed, and nine of these 25 institutions had taken extraordinary steps to avoid failure—either receiving one-off government support, merging with another firm, or submitting to heightened regulation to qualify for future government support. Led by Treasury Secretary Timothy Geithner, the government had to quickly devise policies to stabilize the financial system and the economy. The case explores the details of policies, and the decision making process that led to them, that Geithner and his team devised under immense time pressure to stabilize the system. The case features an extended discussion of Geithner’s innovative “stress test,” which would reveal the longer-term health of the country’s largest banks.
