The 1987 stock market crash occurred with minimal impact on observable economic variables (e.g., consumption), yet dramatically and permanently changed the shape of the implied volatility curve for equity index options. Here, we propose a general equilibrium model that captures many salient...

The 1987 market crash was associated with a dramatic and permanent steepening of the implied volatility curve for equity index options, despite minimal changes in aggregate consumption. We explain these events within a general equilibrium framework in which expected endowment growth and economic...

We study the impact of the 1930s HOLC residential security maps on experienced segregation based on cell phone records which track visits out of and into home neighborhoods. We compare adjacent neighborhoods, one of which was assigned a lower grade for creditworthiness than the other. We use a...

Two-sided market theory predicts that platforms may subsidize the participation of one type of agent by extracting surplus from another type to internalize indirect network externalities. However, few empirical studies exist to evaluate the impact of government intervention in these markets. We...

During the recent financial crisis, the Federal Reserve implemented a series of extraordinary and unconventional policies to alleviate the impact of the crisis on financial markets and the economy. In this paper, we examine the effects of these policies on broad financial market conditions,...

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...

Governments often attempt to increase the confidence of financial market participants by making implicit or explicit guarantees of uncertain credibility. Confidence in these guarantees presumably alters the size of the financial sector, but observing the long-run consequences of failed...

Every year over 20 states offer sales tax holidays (STHs) on specific items like clothes, shoes and other items to encourage consumption, effecting over 100 million consumers. We use a unique dataset of credit cards transaction to study the spending response to these holidays. Using a...

Diamond and Dybvig (1983) is commonly understood as providing a formal rationale for the existence of bank-run equilibria. It has never been clear, however, whether bank-run equilibria in this framework are a natural byproduct of the economic environment or an artifact of suboptimal contractual...

Refinancing a mortgage is often one of the biggest and most important financial decisions that people make. Borrowers need to choose the interest rate differential at which to refinance and, when that differential is reached, they need to take the steps to refinance before rates change again....
