I develop a new monetarist model to analyze why an economy can fall into a liquidity trap, and what the effects of unconventional monetary policy measures such as helicopter money and negative interest rates are under these circumstances. I find that liquidity traps can be caused by a decrease...

I build a general equilibrium model of the transmission of monetary policy on bank lending. Bank lending is done by individual banks that face random investment opportunities by creating inside money. Banks are subject to a reserve requirement and have access to the interbank money market. The...

We investigate how the Mundell-Tobin effect, i.e., a positive relation between in ation and capital investment, changes the optimal monetary policy prescription in a framework that combines overlapping generations and new monetarist models. We find that the Friedman rule is optimal if and only...
