I. Jans et Di. Rosenbaum, MULTIMARKET CONTACT AND PRICING - EVIDENCE FROM THE US CEMENT INDUSTRY, International journal of industrial organization, 15(3), 1997, pp. 391-412
We empirically examine the effect of multimarket contact on pricing in
the U.S. cement industry. A model of price and quantity formation is
estimated for a panel of 25 regional cement markets over 16 years. The
results indicate that the divergence of price from marginal cost in a
particular market is directly related to the extent of multimarket co
ntact among firms in that market.
