Abstract: This study extends the univariate Weibull conditional autoregressive range (CARR) model to establish a bivariate Weibull CARR (BWCARR) model to investigate the range-based volatility spillover effect. The empirical results indicate that a conditional autoregressive range relationship exists on the US, Japan, mainland China, Hong Kong and Taiwan stock markets. The new BWCARR model is more credible and efficient than the CARR model. Moreover, the range-based volatility for the US and Japan has an impact on Taiwan, indicating that there exists a range-based global and regional stock market spillover effect that has an impact on the Taiwanese stock market.

The modern tendency of Japanese politics-economy interaction has affected emerging countries. This article examines the influence of the House of Representatives sessions on returns to Nikkei 225. The conventional linear regression can only describe the impact of averages on returns, but cannot completely present all the possible relationships between the two. In order to avoid the restrictions of the above mentioned method, this article performs quantile regression to analyze the influence of the House of Representatives sessions on the returns of Nikkei 225. Meanwhile, quantile regression provides a more complete description of analysis on relationships between stock market behavior and parliament effects. [ABSTRACT FROM AUTHOR]

Abstract: This paper uses the traditional variance ratio test of Lo and MacKinlay (1988, 1989), the non-parametric-based variance ratio test of Wright (2000) and the multiple-variance ratio test of Chow and Denning (1993), to re-examine the validity of the weak form efficient market hypothesis for foreign exchange markets in four floating-rate markets in neighboring Asian economies (Japan, South Korea, Taiwan and the Philippines). The results show that the random walk patterns of the exchange rate return series cannot be rejected, with the one exception of Taiwan, where inefficiency is shown to be most prominent. We therefore conclude that the foreign exchange markets of Japan, South Korea and the Philippines are weak form efficient, while the foreign exchange market of Taiwan is inefficient.

Abstract: This study adopts the autoregressive conditional jump intensity (ARJI) model proposed by Chan and Maheu [J. Business Econ. Stat. 20 (2002) 377–389] to investigate the impact of news on SIMEX-Nikkei 225 and CME-Nikkei 225 (regards it as the twins). Empirical results demonstrate that the twins were captured by responses to various events; moreover, the twins have distinct jump intensity and risk. Finally, this investigation evaluates the lead–lag relationship between returns and jump behavior by the Granger causality test. Returns are based on unidirectional causality from two futures (the twins) to spot and feedback causality between the twins. Jump intensity reveal feedback causality between spot and the CME-Nikkei 225 and unidirectional causality from the CME-Nikkei 225 to in SIMEX-Nikkei 225. [Copyright &y& Elsevier]
