This article examines changes in state revenue and spending in the 1980s, with particular attention to the period from 1986 to 1989, and discusses likely developments in the 1990s. It incorporates four approaches that can help to improve the policy relevance of research about state-local finances: (1) disaggregating trends in spending, revenue, and different categories of government to a greater degree than usual; (2) employing fiscal data from sources that are often overlooked, particularly sources other than the U.S. Department of Commerce; (3) analyzing both discrete policy actions and changes that occur automatically because of the dynamics of the tax or spending system; and (4) being sensitive to shifts in trends over time.
