Abstract

In some classes of macroeconomic models with financial frictions, an adverse financial shock successfully explains a drop in GDP, but simultaneously induces a stock price boom. The latter theoretical result is not consistent with data from actual financial crises. This study develops a simple macroeconomic model featuring a banking sector, financial frictions, and R&D-led endogenous growth to examine the impacts of an adverse financial shock to banks on firms' R&D investments and equity prices. Both the analytical and numerical investigations show that a shock that hinders the banks' financial intermediary function can be a key to generating both a prolonged recession and a drop in the firms' equity prices.
