Behavioral Economics and Health-Care Markets
By: Amitabh Chandra, Benjamin Handel and Joshua Schwartzstein

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... View Details

Inflation Bets or Deflation Hedges? The Changing Risks of Nominal Bonds
By: John Y. Campbell, Adi Sunderam and Luis M. Viceira
The covariance between U.S. Treasury bond returns and stock returns has moved considerably over time. While it was slightly positive on average in the period 1953–2009, it was unusually high in the early 1980s and negative in the 2000s, particularly in the downturns of... View Details

Liquidity Transformation in Asset Management: Evidence from the Cash Holdings of Mutual Funds
By: Sergey Chernenko and Adi Sunderam
We study liquidity transformation in mutual funds using a novel dataset on their cash holdings. To provide investors with claims that are more liquid than the underlying assets, funds engage in substantial liquidity management. Specifically, they hold substantial... View Details

Behavioral Hazard in Health Insurance
By: Katherine Baicker, Sendhil Mullainathan and Joshua Schwartzstein
A fundamental implication of standard moral hazard models is overuse of low-value medical care because copays are lower than costs. In these models, the demand curve alone can be used to make welfare statements, a fact relied on by much empirical work. There is ample... View Details

Money Creation and the Shadow Banking System
By: Adi Sunderam
Many explanations for the rapid growth of the shadow banking system in the mid-2000s focus on money demand. This paper asks whether the short-term liabilities of the shadow banking system behave like money. We first present a simple model where households demand money... View Details

The Rise and Fall of Demand for Securitizations
By: Sergey Chernenko, Samuel G. Hanson and Adi Sunderam
Collateralized debt obligations (CDOs) and private-label mortgage-backed securities (MBS) backed by nonprime loans played a central role in the recent financial crisis. Little is known, however, about the underlying forces that drove investor demand for these... View Details

Frictions in Shadow Banking: Evidence from the Lending Behavior of Money Market Funds
By: Sergey Chernenko and Adi Sunderam
We document the consequences of money market fund risk taking during the European sovereign debt crisis. Using a novel data set of security-level holdings of prime money market funds, we show that funds with large exposures to risky Eurozone banks suffered significant... View Details

The Growth and Limits of Arbitrage: Evidence from Short Interest

Are There Too Many Safe Securities? Securitization and the Incentives for Information Production
By: Samuel G. Hanson and Adi Sunderam
We present a model that helps explain several past collapses of securitization markets. Originators issue too many informationally insensitive securities in good times, blunting investor incentives to become informed. The resulting endogenous scarcity of informed... View Details

An Activity-Generating Theory of Regulation
By: Joshua Schwartzstein and Andrei Shleifer
We propose an activity-generating theory of regulation. When courts make errors, tort litigation becomes unpredictable and as such imposes risk on firms, thereby discouraging entry, innovation, and other socially desirable activity. When social returns to activity are... View Details

Relative Thinking and Consumer Choice

Selective Attention and Learning
What do we notice, and how does this affect what we learn? Standard economic models of learning ignore memory by assuming that we remember everything. But there is growing recognition that memory is imperfect. Further, memory imperfections do not stem from limited... View Details
