Surprisingly little is known about the importance of mortgage payment size for default, as efforts to measure the treatment effect of rate increases or loan modifications are confounded by borrower selection. We study a sample of hybrid adjustable-rate mortgages that have experienced large rate...

Shiller (2003) and others have argued for the creation of financial instruments that allow individuals to insure risks associated with their lifetime labor income. In this paper, we argue that while the purpose of such assets is to smooth consumption across states of nature, one must also...

The U.S. mortgage market links homeowners with savers all over the world. In this paper, we ask how much of the flow of money from savers to borrowers goes to the intermediaries that facilitate these transactions. Based on a new methodology and a new administrative dataset, we find that the...

We study the evolution of US mortgage credit supply during the COVID-19 pandemic. Although the mortgage market experienced a historic boom in 2020, we show there was also a large and sustained increase in intermediation markups that limited the pass-through of low rates to borrowers. Markups...

I consider four policies created to address the financial crisis: (1) the ability-to-repay requirement in mortgage underwriting; (2) reform of rating agency compensation, (3) risk retention in securitization, and (4) mandatory loan renegotiation. I show that according to standard models,...

The endowment effect is among the best known findings in behavioral economics, and has been used as evidence for theories of reference-dependent preferences and loss aversion. However, a recent literature has questioned the robustness of the effect in the laboratory, as well as its relevance in...

How does an economy behave if (1) fundamentals are truly hump-shaped, exhibiting momentum in the short run and partial mean reversion in the long run, and (2) agents do not know that fundamentals are hump-shaped and base their beliefs on parsimonious models that they fit to the available data? A...

Increasing the diversity of policy committees has taken center stage worldwide, but whether and why diverse committees are more effective is still unclear. In a randomized control trial that varies the salience of female and minority representation on the Federal Reserve's monetary policy...

Technology-based ("FinTech") lenders increased their market share of U.S. mortgage lending from 2% to 8% from 2010 to 2016. Using market-wide, loan-level data on U.S. mortgage applications and originations, we show that FinTech lenders process mortgage applications about 20% faster than other...

We use survey questions about spending in hypothetical scenarios to investigate features of propensities to consume that are useful for distinguishing between consumption theories. We find that (i) responses to unanticipated gains are vastly heterogeneous (either zero or substantially positive);...
