IN THE past thirty or more years, state policy-makers have expanded their efforts to improve the health of their state economies by going beyond traditional road and school building activities. New approaches in this area have included the provision of general obligation and industrial revenue bonds, loans and loan guarantees, tax reductions and exemptions, research and development support, and various programs to direct aid to those who are chronically unemployed. (See ACIR 1963, 1967; Conway 1979; Reinshuttle 1983; Council of State Governments 1976; National Association of State Development Agencies et al. 1984; New York Department of Commerce 1983; U.S. Office of Technology Assessment 1983, for descriptions of state programs.) General studies of the process of creating economic growth stress the many factors involved, including innovation, productivity, employment, and taxation, as well as the difficulty in designing and targeting policies for particular outcomes (Bosworth 1984; Rubin and Zorn 1985; Rasmussen et al. 1982a, 1982b; Nelson et al. 1967; Federal Reserve Bank of Kansas City 1983). State leaders, realizing the complexity of the process of economic growth, have frequently enacted a diverse set of policies. These programs are, in many instances, quite expensive in terms of direct program costs, tax expenditures, or both. One tax expenditure in Arizona for 1984-85 cost the state almost $8 million (Arizona Department of Revenue 1985), while two tax expenditures in Massachusetts in 1986-87 were estimated to cost the state nearly $187 million (Massachusetts House of Representatives 1986). If we add to such figures the amounts of other tax expenditures plus program costs, the totals lie in the billions of dollars of state resources. In most states, data on the costs of tax expenditures are not available.
