Optimal oil import tariffs: An international perspective for the 1980s

Since the oil price explosion of 1973–74, oil policy has focused on two problem areas: firstly, chronically high international oil prices and secondly, vulnerability to disruptions in oil supply. Until recently, many held that measures designed to reduce the level of oil imports would mitigate both of these problems. Oil import reductions would put downward pressure on world oil prices during normal supply conditions, while simultaneously reducing the importer's exposure to oil supply interruptions. By the end of the 1970s, however, several analysts had concluded that certain characteristics of the world oil market would minimize both of these potential benefits of oil import reductions. Now, after more than two years of glut on the world oil market, many doubt that policy-induced import reductions would have any beneficial effects at all. This paper assesses the value of oil import reduction policies during the oil market conditions that are expected to prevail during the 1980s. The conclusion is that there are still substantial benefits to be gained by implementing efficient import reductions. This conclusion is robust over a broad range of assumptions about OPEC objectives and other key determinants of world oil market behaviour.
