I study optimal credit, monetary, and fiscal policy under commitment in a model where financial intermediaries face an occasionally binding financial constraint; the monetary authority faces a zero lower bound (ZLB); and the fiscal authority faces a budget constraint. Despite being inactive...

We estimate how US monetary policies, namely the current fed funds rate, forward guidance, and large-scale asset purchases, affect inflation. The effect of large-scale asset purchases on inflation is found to be much smaller in the intended direction than the other policies. This difference is...

I study the Ramsey problem for three unconventional monetary policies in a twocountry model. An equity injection into financial intermediaries is the most efficient policy. Due to precautionary effects of future risk, a central bank should exit from these policies in accordance with but slower...

We model the real exchange rates between the US and 18 OECD countries by an innovative dynamic process called integral correction mechanism, and allow a real exchange rate equilibrium determined by Harrod-Balassa-Samuelson effects. The Harrod-Balassa-Samuelson effect works through a direct...

We estimate the domestic and international transmission of 4 types of US monetary policy, namely the current fed funds rate, Odyssean and Delphic forward guidance, and large-scale asset purchases. A credit channel is involved in the international transmission, driving large deviations from the...

The Railway Rolling Noise Prediction Software (RRNPS) is a model for predicting the sound pressure levels (SPLs) during a train passage due to wheel/rail roughness, based on vibration dynamics, contact mechanics and sound radiation modules. Similar software has been developed previously, in...
