Traditional location literature concludes that firms will optimally di
fferentiate in order to alleviate a tendency toward competitive pricin
g. However, it has recently been shown that firms will minimally diffe
rentiate if they (correctly) anticipate an absence of price competitio
n. This paper examines the relationship between product location and t
he sustainability of cooperative pricing, in horizontally and vertical
ly differentiated markets. Further, it describes equilibrium locations
when firms are able to choose their locations jointly and when they m
ust choose independently.
