We study whether exchange traded funds (ETFs)--an asset of increasing importance--impact the volatility of their underlying stocks. Using identification strategies based on the mechanical variation in ETF ownership, we present evidence that stocks owned by ETFs exhibit significantly higher...

This paper explores the theoretical and empirical implications of time-varying and unobservable beta. Investors infer factor loadings from the history of returns via the Kalman filter. Due to learning, the history of beta matters. Even though the conditional CAPM holds, standard OLS tests can...

This paper finds that the market betas of value and small stocks have decreased by about 75% in the second half of the twentieth century. The decline in beta can be related to a long-term improvement in economic conditions that made these companies less risky.

We measure the effect of an anti-predatory pilot program (Chicago, 2006) on mortgage default rates to test whether predatory lending was a key element in fueling the subprime crisis. Under the program, risky borrowers and/or risky mortgage contracts triggered review sessions by housing...

The main rationale for policy intervention in debt renegotiation is to enhance such activity when foreclosures are perceived to be inefficiently high. We examine the ability of the government to influence debt renegotiation by empirically evaluating the effects of the 2009 Home Affordable...

We explore the effects of mandatory third-party review of mortgage contracts on consumer choice--including the terms and demand for mortgage credit. Our study is based on a legislative pilot carried out by the State of Illinois in a selected set of zip codes in 2006. Mortgage applicants with low...

Loss mitigation actions (e.g., liquidation or renegotiation) for delinquent mortgages might be hampered by the conflicting goals of claim holders with different levels of seniority. Although similar agency problems arise in corporate bankruptcies, the mortgage market is unique because in a large...

We study a controlled corporate experiment in which loan officers' compensation structure was altered from fixed salary to volume-based pay. The incentives increased aggressiveness of origination: higher origination rates (+31%), larger loan sizes (+15%), and higher default rates (+28%). Under...

Online retailers have gained a total price advantage over brick-and-mortar retailers since the formers generally are not required to collect sales tax. Recently, several states have implemented laws requiring that Amazon collect sales tax during checkout. Using transaction-level data, we...

We explore household consumption surrounding federal tax returns filings and refunds receipt to test various theories of consumption. Because uncertainty regarding the refund is resolved at filing, precautionary savings theory predicts an increase in consumption at this date. Contrary to this...
