Abstract

We have estimated the price effects of two changes in market structure resulting from two changes in the ownership of gasoline refineries in the San Francisco Bay area: Tosco's purchase of Unocal's Rodeo refinery in April 1997 and UDS's purchase of Tosco's Avon refinery in August 2000. These events provide a relatively unique opportunity to test a price concentration relationship. If market concentration is related to price, then we should observe prices increase and then decrease by a similar amount following these transactions. We do not find evidence of a consistent price concentration relationship.
