Rethinking Mortgage Design
Because mortgages make up the majority of household debt in most developed countries, mortgage design has important implications for macroeconomic policy and household welfare. As one example, most U.S. mortgages have fixed interest rates?if interest rates fall, existing borrowers need to refinance to lower their interest payments. In practice, households are often slow to refinance, or may not be able to do so. As a result, the transmission of U.S. monetary policy is dampened relative to countries like the United Kingdom where mortgage rates on most loans adjust automatically with short-term ...

Household Mortgage Refinancing Decisions Are Neighbor Influenced
Can social influence effects help explain regional heterogeneity in refinancing activity? Neighborhood social influence effects have been shown to affect publicly observable decisions, but their role in private decisions, like refinancing, remains unclear. Using precisely geolocated data and a nearest-neighbor research design, we find that households are 7% more likely to refinance if a neighbor within 50 meters has recently refinanced. Consistent with a word-of-mouth mechanism, social influence effects are weaker when neighbors are farther away and non existent for non-occupants. Our results ...

More Tax, Less Refi? The Mortgage Interest Deduction and Monetary Policy Pass-Through
We study how the mortgage interest deduction (MID) constrains mortgage refinancing. Households who deduct mortgage interest from their taxes face a lower post-tax interest rate, reducing the interest savings from refinancing net of taxes. We estimate the effect of the MID on refinancing using the Tax Cuts and Jobs Act (TCJA) of 2017 as a natural experiment. The TCJA doubled the standard deduction, dramatically reducing MID uptake and value. This policy affected borrowers differently based on their pre-existing mortgage interest, federal and state tax rates, and property taxes. We use ...

The Real Term Premium in a Stationary Economy with Segmented Asset Markets
This paper proposes an equilibrium model to explain the positive and sizable term premia observed in the data. We introduce a slow mean-reverting process of consumption growth and a segmented asset market mechanism with heterogeneous trading technology to otherwise a standard heterogeneous agent general equilibrium model. First, a slow mean-reverting consumption growth process implies that the expected consumption growth rate is only slightly countercyclical and the process can exhibit a near zero first-order autocorrelation as seen in the data. The very small countercyclicality of the ...

The Role of Government and Private Institutions in Credit Cycles in the U.S. Mortgage Market
The distribution of combined loan-to-value ratios (CLTVs) for purchase mortgages has been remarkably stable in the U.S. over the last 25 years. But the source of high-CLTV loans changed during the housing boom of the 2000s, with private securitization replacing FHA and VA loans directly guaranteed by the government. This substitution holds within ZIP codes, properties, and borrower types. Furthermore, the two groups exhibit similar delinquency rates. These findings suggest credit expanded predominantly through the increase in asset values rather than a relaxation of CLTV constraints, which ...

Just Released: Subprime Auto Debt Grows Despite Rising Delinquencies
The latest Quarterly Report on Household Debt and Credit from the New York Fed's Center for Microeconomic Data showed a small increase in overall debt in the third quarter of 2016, bolstered by gains in non-housing debt. Mortgage balances continue to grow at a sluggish pace since the recession while auto loan balances are growing steadily. The rise in auto loans has been fueled by high levels of originations across the spectrum of creditworthiness, including subprime loans, which are disproportionately originated by auto finance companies. Disaggregating delinquency rates by credit score ...

The Display of Information and Household Investment Behavior
I exploit a natural experiment to show that household investment decisions depend on the manner in which information is displayed. Israeli retirement funds were prohibited from displaying returns for periods shorter than twelve months. In this setting, the information displayed was altered but the accessible information remained the same. Using differences-in-differences design, I find that this change caused reduction in fund flow sensitivity to past returns, decline in trade volume, and increased asset allocation toward riskier funds. These results are consistent with models of limited ...

The Smart Money is in Cash? Financial Literacy and Liquid Savings Among U.S. Families
Most financial advisors recommend storing three to six months of expenses in liquid assets in case of an emergency. Yet we estimate that more than half of U.S. families do not have at least three months of their non-discretionary expenses in liquid savings. We find that financial literacy is strongly predictive of having three months of liquid savings, controlling for income, income variability, and even parental resources. We also find that financial literacy predicts liquid savings across the income distribution. These results indicate that accumulation of an emergency fund is not ...

Household Finance after a Natural Disaster: The Case of Hurricane Katrina
Little is known about how affected residents are able to cope with the fi nancial shock of a natural disaster. We investigate the impact that flooding from a major US hurricane had on household finance. Spikes in credit card borrowing and overall delinquency rates for the most flooded residents are modest in size and short-lived. Greater flooding results in larger reductions in total debt. Lower debt levels appear to be driven by homeowners using flood insurance to repay their mortgages rather than to rebuild. Debt reductions are larger in census tracts where mortgages were likely to be ...

The Opioid Epidemic and Consumer Credit Supply: Evidence from Credit Cards
Using a unique data set of unsolicited credit card offer mailings by banks to consumers, we investigate how opioid abuse affects consumer credit supply in the U.S. To identify causal effects, we employ instrumental variables, propensity score matching, and contiguous counties techniques and control for varying local economic conditions and demographics. We find that banks contract credit supply to consumers in counties highly exposed to opioid abuse by offering higher interest rates, lower credit card limits, and fewer rewards and reducing credit offers overall. Further analyses using the ...
