Template-Type: ReDIF-Paper 1.0 Title: Household Debt and Crises of Confidence Author-Name: Thomas Hintermaier Author-Email: hinterma@uni-bonn.de Author-Name: Winfried Koeniger Author-Email: winfried.koeniger@unisg.ch Classification-JEL: E21, E32, D91 Keywords: Household debt, Consumer confidence, Collateral constraints, Multiple equilibria Abstract: We show that the size of collateralized household debt determines an economy’s vulnerability to crises of confidence. The house price feeds back on itself by contributing to a liquidity effect, which operates through the value of housing in a collateral constraint. Over a specific range of debt levels this liquidity feedback effect is strong enough to give rise to multiplicity of house prices. In a dynamic setup, we conceptualize confidence as a realization of rationally entertainable belief-weightings of multiple future prices. This delivers debt-level-dependent bounds on the extent to which confidence may drive house prices and aggregate consumption.
