It has been contended that basing-point pricing (BPP) is not indicativ
e of anticompetitive behavior because a cartel would never attain maxi
mum profits by using BPP. We disprove this contention. BPP is the prof
it-maximizing pricing strategy for a cartel that faces competition onl
y at selected locations. In addition, our model explains the emergence
of multiple basing points, and establishes that BPP must be consisten
t with a market-division scheme.
