This study assesses the adequacy of Florida's tax structure to meet future demands for government services through an analysis of Florida's major revenue sources (sales tax, gasoline tax, beverage tax and licenses, motor vehicle licenses, racing tax, and cigarette tax) to determine their stability and growth characteristics. The analysis involved measurement of changes in revenue collections and their relationship to changes in income, changes in population, and changes in prices. More specifically, the analysis involved: measurement of the selected changes over time to determine their long-run average effect on revenues; estimates of the short-run response of revenues to the selected changes; and an analysis of growth and predictability of each revenue source. Findings of the study indicate a major part of Florida's revenues are structurally inadequate to deal with the present and future needs of the state. If population growth or inflation continues, as is commonly assumed, the state will be faced periodically with revenue shortages. Even if price stability is achieved and economic population growth are slower than expected, these sources cannot be expected to provide stable revenues. (Author/JG)
