      abstract = {The purpose of the research presented in this study is to  examine the
relationship of price dispersion to search  costs, store choice, and market power
in the food-retailing  sector. The study used consumer level  demographic
information and brand level fluid milk  consumption data from 33 U.S.
metropolitan areas. Overall,  the study found strong evidence of search cost
related  strategic firm and consumer behavior. Our results show that  purchase
frequency has a negative and significant  relationship with price dispersions and
with measures of  price cost margins. We also find that the price of fluid  milk
was an important factor in explaining whether or not  consumers return to the
same store. Demographic factors  such as income and race were important in
explaining price  dispersions, which suggest different willingness to search  across
population sub-groups.},
