This volume, originally published in 1983 investigates join venture participants in outer continental shelf sales from institutional, theoretical and statistical points of view. It includes a section on the 1975 joint bidding ban, which reviews the principal study which led to the ban and several which are critical of it. The study of ofshore leasing sales goes far beyond the field of economics and this volume will therefore be of interest to those in geology and geophysics, finance, law, politics and statistics.
