Do Higher Oil Prices Still Benefit ? Stephen P. A. Brown and Mine Yücel

Texas and oil. These two words have gone hand in hand since 1889, when the state started producing oil. Since then, the Texas economy has often been driven by volatileT energy prices—suffering with low oil prices and benefiting with high oil prices. The effects of energy prices on the Texas economy were particularly evident during the 1970s and 1980s (Chart 1). As energy prices rose, the Texas economy expanded at a rapid pace, with strong employment and income growth. Although the Texas economy continued to expand until 1986, the oil and gas sector began to slip as energy prices slid from their 1981 heights. The oil price collapse in July 1986 touched off a statewide reces- sion and significant job losses. Since the early 1980s, however, the Texas energy industry has shrunk and other sectors of the Texas economy have grown. Despite these changes, Texas remains the top oil and natural gas pro- ducer in the United States and exports most of its production of these two com- modities to other states. Consequently, the energy industry remains an important driver of the state economy. The diversification of the Texas econ- omy away from energy and this sector’s continuing importance to the state prompt us to consider: How much do swings in energy prices affect the Texas economy today? How much has that rela- tionship changed since the energy boom years of the 1970s and 1980s?

Oil Production in Texas: A Brief History1 The first economically significant oil in Texas was discovered in Corsicana in 1894. Discoveries in Navarro County fol- lowed. By 1901 the oil field was producing 75,000 barrels per day and had contributed to the first Texas . In the early 1900s, Texas produced rel- atively little oil and gas—crude oil pro-
