　概要を見る

<p>In this paper, to study the alternative monetary transmission mechanism to the traditional interest rate channel which may even work under zero nominal interest rates, we estimate the monetary business cycle model of the Japanese economy that incorporates the direct role of money. Estimation is conducted on the system of equations in a state-space form via maximum likelihood estimation. We, however, find that the direct effect of money is extremely small in Japan. This finding is the same as those obtained for the U.S. in Ireland [Ireland, P., 2004. Money's role in the monetary business cycle. Journal of Money, Credit and Banking 36, 969-984] and the Euro area in Andres et al. [Andres, J., Lopez-Salido, D., Valles, J., 2001. Money in an Estimated Business Cycle Model of the Euro area. Working Paper 121, Bank of Spain].</p>

Monetary policy at the zero interest bound

<p>In this paper, we summarize the findings from zero-interest-bound simulation exercises conducted on the policy/forecasting models of the three major central banks. After imposing a fixed-period zero-interest-bound episode on each model, we consider common variations in the monetary-policy reaction function to minimize the macro-economic consequences of such a deflationary regime. Although there is some heterogeneity in the ranking of these remedial policies, reflecting the different properties of the models, we find that more aggressive policy rules and price-targeting rules are potentially candidates for robust monetary strategies.

Effectiveness of state-contingent monetary policy under a liquidity trap

Recent economic developments in Japan suggest that there is a growing interest in how monetary policy should be conducted under low inflation and nominal interest rates. In this paper, we first confirm the effectiveness of conventional wisdom against a liquidity trap, namely taking aggressive responses around the zero bound and variant of price level targeting so that it can intensify the policy duration effect, in the large scale dynamic general equilibrium model, the JEM (Japanese Economic Model). We then show that the optimal tangible policy rules around the zero bound are possibly state-contingent at the same time. J. Japanese Int. Economies 20 (3) (2006) 364-379. © 2006 Elsevier Inc.

Evaluating monetary policy when nominal interest rates are almost zero

　概要を見る

The non-negativity constraint on nominal interest rates may have been a major factor behind a putative structural break in the effectiveness of monetary policy. To check for the existence of such a break without making prior assumptions about timing, and to enable comparison between pre- and post-break monetary policy, we employ an identified Markov switching VAR framework. Estimation results support the existence of a structural break around the time when the de facto zero nominal interest rate policy was resumed and the effectiveness of monetary policy is seen to weaken since then although slightly positive effects from monetary easing still exist.

　概要を見る

Reflecting recent economic developments in Japan, there is a growing interest in how monetary policy should be conducted under low inflation and nominal interest rates. Among several proposed solutions, the conventional wisdom seems to be to commit to lower future short-term nominal interest rates through some variation on price-level targeting. We confirm the effectiveness of such a policy in a large-scale dynamic general equilibrium model: the Japanese Economic Model. However, uncertainty - which affects how monetary policy should be conducted - increases in the presence of the zero bound on nominal interest rates. We posit that the increased uncertainty may explain why the central bank cannot fully commit to a certain fully specified policy scheme far into the future when the economy is caught in a liquidity trap. © Blackwell Publishing Ltd. 2005.
