| Tiivistelmä: | A "transaction" data-base is employed to study whether observed quote-revisions are consistent with those predicted by the adverse selection and inventory cost theories of the bid-ask spread. Actual quote-revisions are found to be consistent with the theoretical prediction in only 25 p.c. of the cases. Quote-revision patterns are strongly dependent on the level of the outstanding spread and, to a lesser extent, on the transaction size. These systematic patterns, unrelated to the inventory cost and adverse selection theories, are consistent with the effect on quote-revisions of the limit order book and the minimum 1/8 price-change rule. |
