DP13072 Monetary Easing, Investment and Financial Instability
This paper studies a model in which a low monetary policy rate lowers the cost of capital for firms, thereby spurring productive investment. Low interest rates however also induce firms to lever up so as to increase payouts to shareholders. Such leveraged share buybacks and productive investment compete for funds, so much so that the former may crowd out the latter. Below an endogenous lower bound, monetary easing generates only limited capital expenditures that come at the cost of large and destabilizing financial risk-taking.
