The purpose of this paper is to provide information concerning the nature of cost conditions with the preprivatization telecommunications industry in the United Kingdom. In particular, the issue of whether the overall cost function is subadditive and whether joint production characterizes the industry is examined. Using cointegration, it is found that for the period 1951/52-1980/81, telecommunication production in the inland and international areas were characterized by cost complementaries; hence joint production was a feature of the U.K. telecommunications industry.
