Despite the widespread belief that technology shocks are the main source of business fluctuations, recent empirical studies find that an investment efficiency shock mainly drives such fluctuations and reflects financial conditions for investment. This poses the question as to what is the major...

This paper proposes a new econometric framework for estimating trend inflation and the slope of the Phillips curve with a regime-switching model. As a unique aspect of our approach, we assume regimes for the trend inflation at one-percent intervals, and estimate the probability of the trend...

In this paper, we calculate the potential output and the output gap using a Bayesian-estimated DSGE model of Japan's economy. The model is a two-sector growth model that takes into account growth rate shocks including investment-goods sector-specific technological progress. For bridging the gap...

A standard growth accounting exercise indicates that, after Japan's "lost decade," its overall total-factor-productivity (TFP) growth has increased notably since 2000. This productivity revival has been limited, however, to information technology (IT) production--has not been a broad-based...

In this paper, we assess the effects of fiscal policy in Japan using two dynamic stochastic general equilibrium (DSGE) models. One is a medium-scale DSGE model of Japan's economy ("M-JEM," Fueki et al., 2010) estimated using Bayesian techniques. The other is the IMF's multi-region "GIMF (Global...
