Were there structural breaks in the effects of Japanese monetary policy? Re-evaluating policy effects of the lost decade

Abstract

Inoue, Tomoo, and Okimoto, Tatsuyoshi-Were there structural breaks in the effects of Japanese monetary policy? Re-evaluating policy effects of the lost decade This paper employs block recursive structural VAR models with Markov switching for modeling monetary policy and private sector behavior of the Japanese economy. By estimating the endogenous structural breaks, we investigate the existence, number, and nature of breaks possibly implied by the monetary policy adopted between 1975 and 2002. Results indicate that the Japanese economic system is best described by a non-absorbing two-state model, with major break happened around 1996. We also confirm that the interest rate monetary policy was effective before 1996, while monetary base shocks are identified as monetary policy shocks only after 1996.

Does the price of oil interact with clean energy prices in the stock market?

“…To capture the possible time variation in the interrelations between oil and stock markets, we introduce the MS framework into the recursive structural VAR model according to Sims and Zha (2006) and Inoue and Okimoto (2008). With this specification, the reduced-form VAR model (1) …”

Effects of the Bank of Japan’s current quantitative and qualitative easing

“…They discussed its positive impacts on the economy with a near-zero interest rate policy. For the case of Japan's QE, Fujiwara (2006), Inoue and Okimoto (2008), and Hayashi and Koeda (2014) applied a vector autoregression (VAR) model with a Markovswitching structure in their analyses. They discovered that in the past, a regime change in Japan occurred either in the initial stages of the liquidity trap (in 1996) …”

Bayesian analysis of time-varying parameter vector autoregressive model for the Japanese economy and monetary policy

“…Since Miyao (2000, 2002 analyzed the Japanese economy using a vector autoregressive (VAR) model, the time variation of the relations among Japanese macroeconomic variables has been investigated in several studies (e.g., Fujiwara (2006), Inoue and Okimoto (2008) using a Markov-switching VAR model, and Kimura et al (2003) using a VAR model with time-varying coefficients). In these studies, the changes in the coefficients in the VAR system are well studied, although the variance of the structural shocks is assumed constant over the sample period or subsample period.…”
