Monetary policy shocks in the United States are considered a significant cause of economic fluctuations in other countries. We study empirically how the spillover effects of such shocks have changed as a result of the recent deepening of global integration. We consider shocks to the Federal...

Due to a sharp decline in the fertility rate and a rapid increase in longevity, Japan's population aging is the furthest advanced in the world. In this study we explore the macroeconomic impact of population aging using a full-fledged overlapping generations model. Our model replicates well the...

Since the mid-1990s, the asset portfolios of Japanese banks have continuously tilted toward government bonds, while lending to firms has declined. In this paper, we investigate the causes and consequences of such changes in banks' behavior by introducing banks' asset portfolio decision into an...

This paper examines the Purchasing Power Parity (PPP) hypothesis of the yen-dollar exchange market by taking into account the following four points: accumulated current accounts as an additional variable, more powerful tests of Horvath and Watson(1995), more appropriate critical values through...

We estimate a medium-scale DSGE model of the Japanese economy following Christiano, Eichenbaum and Evans (2005), Smets and Wouters (2003) and Levin et al. (2005). By using actual capital utilization data and modifying the formulation of utilization following Greenwood, Hercowitz and Huffmann...

This paper tries to shed light on the optimal inflation rate by investigating the effects of changes in inflation on resource allocation via changes in the effective tax rates. Given that some taxes are not lump-sum but subject to the proportional/progressive tax schedule, and that taxes are...

We consider a competitive bank loan market model where the marginal costs of managing and monitoring loans are assumed to increase as borrowers' net worth decreases. We show that the responsiveness of equilibrium bank loan rates to changes in interbank money market rates become weaker as...
