Risk endogeneity at the lender/investor-of-last-resort, joint with Diego Caballero, Andre Lucas, and Xin Zhang.
[submitted]
(Most recent version: Oct 2018)
We study the time-variation in central bank portfolio credit risks associated with unconventional monetary policy operations.
Overall risk can be nonlinear in exposures. Some policy operations reduced rather than added to overall risk.

Work in progress
