This study explores the impacts on small securities firms' performance of the multi-stage commission deregulation in Japan from 1994 to 1999. Different from previous findings, market volume does not rise while commission rates fall following each phase of the deregulation. Therefore, securities...

This study investigates the Nikkei 225 rebalancing. Unlike those for changes in the Samp;P 500, the price effects are permanent for both additions and deletions despite significant price reversals around both the announcement and effective days. The permanent price effects are shown to be...

This study investigates for the first time the effects of involuntary foreign delistings from the U.S. stock exchanges. Upon announcement of delisting, prices drop a significant 4.5% permanently. The price effects do not seem to differ significantly by various measures of differential market...

Theories predict that introduction of option trading should affect the pricing efficiency in the underlying stock market.

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 S&P 100 options in March 1983. Controlling for...
