| 摘 要： | 本文以Lo and Mackinlay(1988,1989)1]2]的方差比率为基础,构建了考察股市噪音成分的MCT指标,并对亚洲七个国家和地区的股市进行了检验。结果发现中国大陆和泰国股市具有更大的噪音成分,市场效率性较差;香港地区、台湾和日本股市则具有较小的噪音交易成分,且无法拒绝不存在噪音交易的零假设;马来西亚和印度尼西亚的市场表现则处于前两者之间。最后我们通过Bootstrap对检验进行了重新评估,发现本文的检验结果是稳健的。

| Abstract: | Based on the variance-ratio test of Lo and Mackinlay(1988,1989),I construct a noise composition test(NCT) index in this paper and give an empirical test to seven Asian stock markets.I find the the markets of mainland of China and Thailand have more noise composition and are more inefficient.Meanwhile,the markets of Hong Kong,Taiwan,and Japan have a smaller noise composition and I cannot reject the zero hypothesis of price which is following a random walk.At last,I use the Bootstrap sample to re-estimate the previous results and find it is robust. |
