The impact of settlement time on the volatility of stock markets

چکیده
In this paper we investigate the impact of the switching from the same-day settlement to the following-day settlement on the market volatility and its structure. Using the Levene tests and bootstrap procedures, we find that the switching causes a drastic decrease in the stock market volatility. In addition, using a modified GARCH model, we also find a substantial change in the volatility structure, which implies that the markets become less efficient after the switching since the volatility shocks are less quickly assimilated in the stock markets.
