Page 7: The Credit-Driven Household Demand Channel · The Credit-Driven Household Demand Channel Atif Mian Princeton University Nobel Symposium On \Money and Banking" May 24, 2018 1/22. 2/22

Outline

• Evidence from business cycles internationally, as well as regional business cycleswithin the U.S., over the last half-century

• International evidence - including a new out of sample test of previous findings

• A natural experiment using the U.S. banking deregulation wave from the 1980s

• U.S. regional evidence from the Great Recession

• Implications of the credit-driven household demand channel for

• Macroeconomic theory and long run fundamentals

• Public policy (monetary policy, macro-prudential policy, and crisis response)

4 / 22

Page 8: The Credit-Driven Household Demand Channel · The Credit-Driven Household Demand Channel Atif Mian Princeton University Nobel Symposium On \Money and Banking" May 24, 2018 1/22. 2/22

Empirical Challenges

• How to isolate credit supply expansion?

• ↑ in quantity and ↓ in spreads, deregulation/policy experiments, differentialpass-through of global shocks (e.g. oil, securitization, savings glut)

• How to identify change in household aggregate demand?

• Focus on nontradable/tradable sectors, relative size and prices

• Asymmetry between household and non-financial firm credit

• Use of micro data and regional variation

U.S. experience during the 2000’s

• A large expansion in credit supply, Mian and Sufi (2009), (also see [1])

• Credit expansion led to an increase in local demand and the non-tradable sectorexpanded, Di Maggio and Kermani (2017)

• When the music stops, Fisher’s “debt deflation” dynamics take hold (see [2])

• large fall in demand, Mian et al. (2013)

• fall in employment due to demand shortgage, Mian and Sufi (2014)

• foreclosure fire-sale externalities amplify the negative cycle, Mian et al. (2015)

Public policy implications of credit-driven household demand channel

• Post-2007 policy should have focused on reducing household debt servicepayments and preventing foreclosures (see [8]).

• Mortgage design matters, more equity-like contracts that promote risk-sharinghave benefits at the macro level

• Monetary policy pass-through depends on the credit-driven household demandchannel, e.g. Di Maggio et al. (2017)

• UK and many other countries have since adopted macro-prudential regulationsthat impose constraints based on loan to value or debt service to income
