How large-scale asset purchase (LSAP) programs affect financial markets is an important question for policy makers that face the zero lower bound. In this paper, we analyze so-called “flow effects” that may occur at the time of LSAP transactions. Using security-level transaction data related...

We investigate how liquidity regulations affect banks by examining a dormant monetary policy tool that functions as a liquidity regulation. For causal inference, we use a regression kink design that relies on the variation in a marginal high-quality liquid asset (HQLA) requirement around an...

We identify all return leader-follower pairs among individual stocks using Granger causality regressions. Thus-identified leaders can reliably predict their followers' returns out of sample, and the return predictability works at the level of individual stocks rather than industries. Our results...
