Monetary policy and growth with trend inflation and financial frictions

This paper studies the effects that conventional and unconventional monetary policies generate when endogenous growth, trend inflation and financial frictions are considered in a New Keynesian macroeconomic model. Financial variables play a key role in the determination of the steady state growth rate, given the value of the trend inflation. Calibrating the model following Gertler and Karadi (2011), long-run growth rate, welfare, normalized investment and financial wealth are maximized when trend inflation is 1.7% while leverage, external finance premium and marginal gain of the financial intermediaries are minimized. Finally, unconventional policies could extend their impact to the long run.
