We further explore a new volatility explanation for the permanent price effect of index additions, using a sample of changes in the Nikkei 225. Additions to the index elicit significant price hikes, which tend to be permanent despite temporary price reversals. Meanwhile, investor awareness and...

This study analyzes the impacts of explicit transaction costs on weak-form market efficiency within the context of the brokerage commission deregulation in Japan in October 1999, which led to lower commission rates across the market. Applying two alternative statistical tests to both daily and...

This study examines the effect of transaction costs on the time series behavior of stock returns over a period surrounding the April 1989 changes in tax rates on securities transactions and capital gains in Japan. We find significant decreases in estimates of the first-order autocorrelation in...

We investigate the volatility impacts of the full commission deregulation in Japan in October 1999, and find that the deregulation overall tends to significantly increase price volatility in the Japanese equity market, using alternative model specifications and control variables. This finding...

There has been very limited evidence about the impact of index derivatives on the informativeness of the underlying stocks' prices, despite its empirical nature. We explore this issue in this study, employing the introduction of the S&P 100 options. We find that, net of the market, the...

We investigate possible reasons for voluntary delistings by U.S. firms from the Tokyo Stock Exchange from 1982 to 2005. We find that the small shareholder base, as measured by low turnover, for U.S. stocks in Japan helps to explain the voluntary foreign delistings. This finding is consistent,...

When stocks are added to (deleted from) an index, more (less) information should be generated and incorporated into their prices, leading to higher (lower) pricing efficiency and lower (higher) return predictability for them. We test this hypothesis for the first time using membership changes in...

Theories predict that launching index futures could affect the price informativeness for the underlying stocks. We test this hypothesis by taking advantage of the introduction of the Nikkei 225 futures contracts in Singapore on September 3, 1986. Employing two alternative statistical methods...

Existing theories predict lower trading volume, but ambiguous changes in price, bid-ask spread, and volatility for the underlying stocks following the advent of index derivatives. We further test these predictions around the introduction of the Samp;P 100 options in March 1983. Controlling for...

International cross-listing should subject stocks involved to ameliorated information environment in the host market, resulting in more information being revealed, fed back, and impounded into their prices at home and, thus, higher home-market pricing efficiency. Employing a simple nonparametric...
