Research by Tomasz Piskorski of Columbia Business School and Amit Seru of the Stanford Graduate School of Business demonstrates that regions of the US that received more mortgage debt relief recovered much faster following the Great Recession in terms of consumer spending, employment, and housing prices compared to those that received less debt relief.

Factors Affecting the Extent of Debt Relief and Pass-Through of Lower Rates to Households
The research by Tomasz Piskorski and Amit Seru also shows that there have been significant barriers to provision of effective debt relief by financial sector and pass-through of low interest rates to households. These factors significantly hampered economic recovery following the Great Recession.
Piskorski and Seru findings suggest that solely relying on private sector for implementation of effective debt relief polices is challenging. Moreover, the considerable regional heterogeneity in economic conditions indicates that one-size-fits-all polices are not that effective and there are significant gains from tying debt relief polices to local economic conditions.
For an overview of these barriers and their implications for mortgage market design and future policy interventions see:
- “Mortgage market design: Lessons from the Great Recession”, T Piskorski and A. Seru, Brookings Papers on Economic Activity Spring 2018.
Below is a list of factors that were shown to adversely affect the extent of debt relief and pass-through of low interest rates to households:
- Mortgage contract rigidity limiting pass-through of lower rates to households: The rigidity of fixed rate mortgages (FRMs), in contrast to more flexible ARMs, hampers the pass-through of debt relief during periods of low interest rates. In particular, the reduction of interest rates during the Great Recession provided borrowers with certain types of ARMs an automatic debt relief, which was not available to households with FRMs.

- Refinancing constraints limiting pass-through of lower rates to households: Households with fixed rate mortgages, the predominant financial obligation of U.S. households, rely primarily on refinancing to receive debt relief from the low interest rate environment induced by monetary policy. Many of these households were left with little equity as house prices dropped during the Great Recession, making them ineligible for loan refinancing that requires a certain amount of borrower equity. In addition, limited competition in the refinancing market and intermediary capacity constrains have also limited the effectiveness of the Home Affordable Refinance Program aimed at facilitating refinancing of such insufficiently collateralized loans.

- Limited organizational capability of intermediaries to perform loan modifications: The U.S. economy experienced limited loan restructuring during the Great Recession, despite the surge in distressed borrowers. Financial intermediary specific factors impacted the extent of debt relief that was passed to households (and regions), with certain intermediaries having the organizational ability to renegotiate loans significantly more than others. These factors have also limited the effectiveness of the Home Affordable Modification Program that provided financial institutions with monetary incentives to renegotiate distressed mortgages.

- Limited incentives of financial institutions to modify securitized debt that they service for others: Financial institutions were much less likely to renegotiate loans of distressed borrowers if they service these loans for others due to securitization compared to loans they own.
- See Piskorski, T., A. Seru, and V. Vig, 2010, Securitization and Distressed Loan Renegotiation: Evidence from the Subprime Mortgage Crisis, Journal of Financial Economics 97, 369- 397.
- Concerns of financial intuitions that debt relief programs may induce excessive defaults by households: Limited loan restructuring activity can also reflect lenders’ concerns about future moral hazard by borrowers and the inability of lenders to evaluate the repayment ability of borrowers.
