@article{172911, author = {Markus K. Brunnermeier}, title = {Feedbacks: Financial Markets and Economic Activity}, abstract = { Is credit expansion a sign of desirable financial deepening or the prelude to an inevitable bust? We study this question in modern US data using a structural VAR model of 10 monthly-frequency variables, identified by heteroskedasticity. Negative reduced-form responses of output to credit growth are caused by endogenous monetary policy response to credit expansion shocks. On average, credit and output growth remain positively associated. {\textquotedblleft}Financial stress{\textquotedblright} shocks to credit spreads cause declines in output and credit levels. Neither credit aggregates nor spreads provide much advance warning of the 2008-9 crisis, but spreads improve within-crisis forecasts. }, year = {2021}, journal = {American Economic Review}, volume = {111}, pages = {1845-1879}, url = {https://www.aeaweb.org/articles?id=10.1257/aer.20180733}, language = {eng}, }
