This paper analyzes the effects of monetary policy shock when there is a non-negative constraint on the nominal interest rate. I employ two algorithms: the piecewise linear solution and Holden and Paetz's (2012) algolithm (the HP algorithm). I apply these methods to a dynamic stochastic general...

Many immunization strategies have been proposed to prevent infectious viruses from spreading through a network. In this study, we propose efficient immunization strategies to prevent a default contagion that might occur in a financial network. An essential difference from the previous studies on...

Recent monetary policy analyses show the profound implications of progressive taxation for monetary policy. This paper investigates how progressive taxation on labor income alters the effect of model uncertainty by introducing robust control. We analyze the effect by deriving closed form...

A number of previous studies suggest that inflation expectations are important in considering the effectiveness of monetary policy in a liquidity trap. However, the role of inflation expectations can be very different, depending on the type of monetary policy that a central bank implements. This...

Recent monetary policy studies have shown that the trend productivity growth has non-trivial implications for monetary policy. This paper investigates how trend growth alters the effect of model uncertainty on macroeconomic fluctuations by introducing a robust control problem. We show that an...

After the colossal financial crisis of 2008, many monetary policy analyses have shown the profound implications for financial stability of monetary policy in a liquidity trap. This paper investigates how monetary policy in a liquidity trap affects financial stability in a New Keynesian model...
