basically, the price drop depends on:- spread between the dividend tax rate and the capital gains tax rate for a particular stock [the so called "clientele effect" (Elton and Gruber, 70) - some investors prefer higher dividend stocks and others do not => market segmentation]- the possibility to economically trade around the dividend date (see michaely and vila...)among investors taxed differently on div and capital gains.
