This paper investigates the equilibrium relationship between the nominal interest rate and inflation rate in Japan using a threshold cointegration test, which allows for asymmetric adjustment. While the Engle-Granger method assuming symmetric adjustment cannot obtain the result of cointegration,...

This paper investigates the term structure of interest rates in Japan using the unit root test in a nonlinear STAR framework. The results provide strong evidence against the unit root of the yield spread between long-term and short-term interest rates, compared with standard unit root tests...

This study compares the size and power of autoregressive conditional heteroskedasticity (ARCH) tests that are robust to the presence of a misspecified conditional mean. The approaches employed are based on two nonparametric regressions for the conditional mean: an ARCH test with a...

This study examines the asymmetric effect of trading volume on realized volatility. The study introduces new realized volatility models to examine this effect: one model uses asymmetric trading volume variables based on intraday returns, and the other uses asymmetric trading volume variables...
