Starting observation (ex-post) • Eggertsson and Krugman (2012) • Distributional shocks matter ex-post in the presence of ZLB type of constraints. • Series of papers by Jorda, Taylor and Schularik provide some fascinating historical evidence • Caution: not clear in the empirical literature that the ZLB is “necessary” • Possible tension with theory. • Would be nice to explore other possible frictions • Other work
Can monetary policy solve this problem? • Not really
Ex-ante decision making • Is ex-ante borrowing / lending decision going to incorporate the ex-post (stochastic) macro effects of debt? • No, there is an “aggregate demand externality” • d vs. D • Get inefficient outcome even with complete markets • Farhi and Werning, Korinek and Simsek
Credit cycles and inequality • The discussion has to involve income and wealth inequality as well • Lenders and borrowers differ systematically • The paper is agnostic about the “timing” of credit cycles • But evidence suggests that the “credit cycle” is related to rising inequality • Could credit cycle be a GE “response” to disequilibriating forces?
Relevant forces outside of model • Non-standard preferences • What if a quarter to one-third of the population was myopic? • Fire sale externality • Equally important • Employment feedback
Mandating change? • Mandating / subsidizing state-contingent financial contracts that automatically redistribute towards the more constrained agents ex-post • Getting rid of the bias induced by capital regulation • Getting rid of the bias induced by tax policy • Our financial regulation and tax policy makes no sense from a macro stability perspective. • This paper crystallizes some of the core issues in this debate.
Concentration of Losses • Debt concentrates risk on the debtor – the lender largely escapes unscathed • Who are lenders? Debt and inequality naturally connected
