Theory suggests that government aid to banks may either reduce or increase systemic risk. We are the first to address this issue empirically, analyzing the Troubled Assets Relief Program (TARP). Analysis suggests that TARP significantly reduced contributions to systemic risk, particularly for larger and safer banks, and those in better local economies. This occurred primarily through a capital cushion channel that reduced market leverage by increasing the value of common equity. Results are robust to endogeneity and selection bias checks. Findings yield policy conclusions about whether to aid banks, the best targets for future assistance, and short-term versus long-term effects.

We study how employment documentation requirements and out‐of‐pocket closing costs constrain mortgage refinancing. These frictions, which bind most severely during recessions, may significantly inhibit monetary policy pass‐through. To study their effects on refinancing, we exploit a Federal Housing Administration policy change that excluded unemployed borrowers from refinancing and increased others' out‐of‐pocket costs substantially. These changes dramatically reduced refinancing rates, particularly among the likely unemployed and those facing new out‐of‐pocket costs. Our results imply that unemployed and liquidity‐constrained borrowers have a high latent demand for refinancing. Cyclical variation in these factors may therefore affect both the aggregate and distributional consequences of monetary policy.

The pace of job reallocation has declined in the United States in recent decades. We draw insight from canonical models of business dynamics in which reallocation can decline due to (i ) lower dis persion of idiosyncratic shocks faced by businesses, or (ii ) weaker marginal responsiveness of businesses to shocks. We show that shock dispersion has actually risen, while the responsiveness of business-level employment to productivity has weakened. Moreover, declining responsiveness can account for a significant fraction of the decline in the pace of job reallocation, and we find suggestive evidence this has been a drag on aggregate productivity.
