Conclusion
The Great Recession was notable both for its overall severity and for differential impacts across states and income groups. While state tax revenues took a major hit during the Great Recession, the effect varied widely across states. Thirty-six of the forty-eight contiguous states experienced losses, and by 2014, real tax revenues were still below 2007 levels in many states. While over a third of state tax revenue comes from the personal income tax and a little less than half from taxes on consumption, states vary widely in their relative reliance on each of these taxes. Conventional analyses have attributed interstate differences in the cyclical sensitivity of state tax revenues to differences in their relative dependence on these two types of taxes, based on the notion that the income tax base is more volatile than the consumption tax base.
We propose an alternative model based on the distributional impacts of the recession and the distribution of tax burdens by income segment. Given the overall growth in inequality of incomes and the greater importance of capital gains to top incomes, differences across states in income inequality, and the disparate impacts of the recession by income level, we argue that analysis by segment of the income distribution enhances our understanding of the effect of this extreme business cycle on state tax revenues. We therefore analyze revenue changes as a function of the interaction between the distribution of income changes and the distribution of tax burdens by income level.
