This study analyzes the relevance of capital adjustment and risk-taking adjustment during the financial tsunami when the banking industry was under capital regulation. Using the panel data of commercial banks in the USA and non-USA from 2003 to 2009, we consider the effects of financial freedom, concentration and governance control simultaneously by threestage least square analysis. The results show that capital and risk adjustment are positively correlated for both USA and non-USA banking industry, which are consistent after the financial tsunami. This applies to the verification of the capital buffer theory. In addition, for banks with low capital adequacy ratio, capital and risk adjustment are negatively correlated. This applies to the verification of bankruptcy cost avoidance theory and managerial risk aversion theory. Finally, banks with lower capital ratio will be faster in the adjustment of risk-taking as compared with banks with higher capital ratio. This study recommended that supervision should be coupled with governance control to achieve the goal of reducing risk-taking.

By utilizing vector error correction model (VECM) and EGARCH model, this article uses 5-minute intraday data to examine the interaction of return and volatility between Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) and the newly introduced TAIEX futures. VECM model shows that there exists bi-directional Granger causality between index spot and index futures markets, but spot market plays a more important role in price discovery. The results of impulse response function and information share indicate that most of the price discovery happens in index spot market. The evidence of EGRACH shows that the impacts of spot and futures innovations are asymmetrical, and the volatility spillovers between spot and futures markets are bi-directional. However, the information flow from spot to futures is stronger. These results suggest that the TAIEX spot market dominates the TAIEX futures market in terms of return and volatility. . 255 Rev. Pac.

This article uses daily data from July 21, 1998 to July 31, 2000 to examine the hedging effectiveness, price behavior, and lead-lag relationship of SGX MSCI Taiwan index futures and TAIFEX TAIEX futures. By applying the Bayesian approach using Gibbs sampler, we find that TAIFEX index futures has a better hedging performance. A variance ratio test reveals that mean reversion and negative correlation of returns exist in SGX index futures. Only TAIFEX TAIEX futures is cointegrated with TAIEX spot. The uni-directional Granger causality between the two futures markets and spot market are from SGX to TAIEX and from TAIEX to TAIFEX. In terms of price discovery, SGX MSCI Taiwan index futures play a more important role than TAIFEX TAIEX futures.
