Abstract: | This study examines the impact of unconventional monetary policies on the stock market when the short‐term nominal interest rate is stuck at the zero lower bound (ZLB). Unconventional monetary policies appear to have significant effects on stock prices and the effects differ across stocks. In agreement with existing credit channel theories, I find that firms subject to financial constraints react more strongly to unconventional monetary policy shocks especially large‐scale asset purchases (LSAPs)] than do less constrained firms. These results imply that the credit channel is as important as the interest rate channel in the transmission of unconventional monetary policies at the ZLB. |
