| Abstract: | Exchange minimum price variation regulations create discrete bid-ask spreads. If the minimum quotable spread exceeds the spread that otherwise would be quoted, spreads will be wide and the number of shares offered at the bid and ask may be large. A cross-sectional discrete spread model is estimated by using intraday stock quotation spread frequencies. The results are used to project $ 1/16 spread usage frequencies given a $ 1/16 tick. Projected changes in quotation sizes and in trade volumes are obtained from regression models. |
