How do the oil companies organize their business? What sorts of changes would best serve free-market competition in the abstract, and the actual consumer at the gas pump? Is a solution to the energy crisis to be found in "divestiture" (i.e., ending the practice in which, as Senator Hart puts it, "Whether through the exchange of crude petroleum, whether through joint pipelining arrangements, whether through joint-venturing of refining, whether through a conglomerate of financial arrangements, these firms which control the product from the ground to the gas pump, having these horizontal arrangements among themselves, dominate for all practical purposes anywhere from 75 to 90 per cent of the product at one time or another")? A serious and mostly accessible discussion of these and related questions.
