Oil stands alone among primary commodities in its potential for sending economic shock waves across the world. The value of oil production is one and a half times the world's total production of food grains; demand is unresponsive to price in the short run; and the world's oil resources are heavily concentrated in the Middle East, where political disturbances have been chronic and oil supply is subject to sudden interruption. Together, these factors have made oil a virtual rogue elephant in the world economy since 1973. This book discusses the oil shocks of 1973-74, 1979-80, and the "minishock" of 1990-91, and examines the possibility of oil shocks over the next twenty years. The authors assess the world market outlook on the basis of underlying trends on world oil supply and demand. They take into account prospects for investment in oil production in the Persian Gulf states, the former Soviet republics, and Latin America; environmental factors and policies; and political uncertainties in the Middle East.
