This paper uses data on the prices charged at fast-food restaurants in
the metropolitan Pittsburgh and Detroit areas to assess the effect of
franchising on price dispersion within chains in fairly narrowly defi
ned geographical areas. A review of reasons why firms may face more pr
ice dispersion under franchising guides the empirical analyses. Result
s indicate that I) franchisors do not aim for fully uniform prices eve
n on the corporate side of their chains, 2) the degree of price disper
sion is highest for firms with both franchised and company-owned units
, as predicted by models implying a systematic price differential betw
een units operated under these different contracting mechanisms, and 3
) price dispersion for fully franchised chains is greater than for ful
ly corporate chains. These last two results, combined with evidence fr
om court cases that franchisors sometimes try to control franchisee pr
ices directly, suggest that franchisors indeed lose some amount of con
trol over prices charged to customers when they use franchising as opp
osed to corporate ownership. Finally, I find a positive effect of the
royalty rate on price dispersion. This suggests that double marginaliz
ation is behind at least some of the higher prices found in franchised
units in the existing literature. (C) 1998 Elsevier Science Inc.
