This study's findings, together with the results of earlier studies of the relationship between advertis ing and market prices, provide considerable empirical support for the pro-competitive view of seller advertising. Data on attorney fees an d advertising practices in seventeen metropolitan areas across the U. S. were used to estimate the effect of market advertising intensity o n firm demand elasticities, holding other possible influencing factor s constant. The results obtained for all three routine legal services examined are consistent with the hypothesis that advertising increas es competition among sellers in a market.
