In responding to the extremely weak global economy after the financial crisis in 2008, many industrial nations have been considering or have already implemented negative nominal interest rate policy. This situation raises two important questions for monetary theories: (i) Given the widely held...

We develop a N-sector business cycle network model a la Long and Plosser (1983), featuring heterogenous money demand a la Bewley (1980) and Lucas (1980). Despite incomplete markets and a well-defined distribution of real money balances across heterogeneous households, the enriched N-sector...

The Eurosystem’s Public Sector Purchase Programme (PSPP) increased the scarcity of safe assets, which caused significant declines and substantial dispersion in European repo rates. However, banks holding these safe assets benefited from this development: First, using the German security...

I develop a model that explicitly takes the role of financial institutions in the transmission mechanism of monetary policy into account. Within this model, I find various equilibrium environments, with one of them resembling a standard environment for monetary policy and another one akin to a...

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...

We present a dynamic and monetary model that consistently explains such various phenomena as unemployment, deflation, zero nominal interest rates and excess reserves held by commercial banks. These phenomena are commonly observed during the Great Depression in the United States, the recent...

This paper presents a simple Ramsey-type model example where two infinitely-living agents have same utility function except for time preference, and shows that equilibrium is indeterminate that is to be interpreted as being non-existent. The issues regarding New Keynesian transversality...

Japan has been in a benign liquidity trap since 1990. In a benign liquidity trap, interest rates approach zero, prices decline, and monetary policy is ineffective but output and employment perform decently. Such a pattern contradicts traditional macro theories. This paper introduces a monetary...

This article assesses economic growth in the context of consumer saturation. We show that consumer based economies tend to suffer from demand saturation after an initial and prolonged period of growth. However, structural demand saturation irrevocably triggers a Minsky-type super cycle that is...
