Chapter Outline HISTORICAL VIEW OPEC WHY PRICES CHANGE SO FAST WHAT WILL THE FUTURE HOLD Electricity Prices Historical Events Relating to Oil and Gas Prices 1972 Arab-Israeli War US support for Israel prompted an embargo by Arab oil producers against the US and Europe. This led to a significant increase in crude oil prices. 1979 Iranian Revolution Iran’s Islamic revolution led to instability in the Persian Gulf. This led to a significant increase in crude oil prices. 1980’s Rapid increases in profits led to significant discoveries of oil in Mexico and the North Sea 1980-1988 Iran-Iraq War The war led to increased production by both parties as each needed to fund their war effort. This caused a precipitous fall in crude oil prices. World Oil Reserves Group Billions of Barrels in Reserve Percentage of World Reserves Persian Gulf 664 63% Non-Persian Gulf OPEC 134 13% Rest of the World 238 24% OPEC The Organization of Petroleum Exporting Countries (OPEC) Algeria, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, and Venezuela OPEC began as a cartel. A cartel is an organization of individual competitors that join to form as a single monopolist. Was OPEC a Cartel? OPEC production has always been a significant part of the oil market but it has never reached the level of monopoly. The cartel model is still useful because it has been a dominant player.

Electricity Residential electric power tends to be sold by a regulated monopoly. It has been a monopoly because of significant barriers to entry. It has been regulated because prices would be much higher than is socially optimal. Types of Monopolies Simple Monopoly: a monopoly in which marginal costs of production are rising. Natural Monopoly: a monopoly in which marginal costs of production are falling. Monopoly in the Market for Residential Electricity The market for residential electricity is likely to be a natural monopoly for nuclear power because of the very high fixed costs (transmission lines and the power plant and diminishing marginal costs.) The market may be characterized as a simple monopoly or natural monopoly for coal or gas generated electricity.

California “deregulated” by Having its utilities sell their productive capacity to a variety of competitive producing firms Having them buy electricity from these producers Letting the market price for wholesale electricity float. Continuing to fix residential electricity prices. Natural gas prices increased dramatically The utilities could not buy the power because they were selling it at regulated prices that were lower that the deregulated prices at which they were buying it.
