John E. Anderson of the University of Nebraska, Lincoln and the Lincoln Institute of Land Policy discusses the volatility and resilience of property, sales and income tax revenues, focusing on how they relate to changes in GDP.

3. New Estimates of State and Local Tax Resilience
• Estimate relationship between changes in state GDP and changes in state
and local tax revenue
• Property, income, and sales tax data
• Property tax data: 1967-2012
• Income and sales tax data: 1972-2012
• Estimate two relationships:
• Long-run buoyance: change in revenue in response to change in state GDP
• Error correction: response following a GDP shock, returning to long-run equilibrium
4. Two Measures of Resilience
• Buoyance measures the long-run relationship between changes in state GDP
and changes in tax revenue
• No adjustments for policy offsets (i.e. tax rate or base changes)
• A buoyancy estimate of 1.0 indicates that a one percent change in GDP results in a one
percent change in tax revenue
• An estimate less than 1.0 indicates a less than proportionate change in tax revenue
• An estimate more than 1.0 indicates a more than proportionate change in tax revenue
• Error correction term measures how a tax system responds to a GDP shock
as it adjusts to its long-run equilibrium
• A negative sign indicates that a positive error in the previous year (revenues above trend) is
followed by a negative adjustment in the following year
5. Tax Buoyancy and Error Correction Estimates, Overall
Estimates for the 50 States and D.C.
Property Tax Income Tax Sales Tax
Long-run buoyancy 0.78 1.06 0.90
Error correction -0.75 -0.21 -0.81
• The property tax is the most stable revenue source with a long-run buoyancy estimate less than
one; followed by the sales tax which is more buoyant
• The income tax is the least stable revenue source, reacting more than proportionately to state
GDP shocks
• In terms of error correction, adjusting to shocks that displace states from their long-run equilibrium,
the sales and property tax systems adjust more quickly, while income tax systems adjust much
more slowly

7. Long-Run Tax Buoyancy—New England States
• Property tax:
• CT, NH and VT have property tax buoyancy in the range of 0.8 to 1.0, somewhat less than
proportional responses to changes in state GDP
• ME, MA, and RI have no buoyancy, i.e. fluctuations in state GDP have little or no impact on
property tax revenues
• Income tax:
• CT has an extremely volatile income tax system (4.6)
• MA, RI, and VT have buoyancy estimates that are greater than one indicating more than
proportional responses to changes in state GDP (1.1 to 1.2)
• Sales tax:
• VT has unitary buoyancy (1.0)
• ME, MA, and RI have buoyancy of about 0.8, indicating less than proportional response
• CT has a less response sales tax system (0.5)

9. Error Correction Terms—New England States
• Property tax:
• Error correction terms are strongest for property tax systems
• For all New England states, except CT, the error correction terms are in the range of 1.0 to
1.1, indicating quick recovery after a GDP shock
• Income tax:
• Error correction terms for CT, MA, and VT are much smaller, in the range of 0.3 to 0.6,
indicating slow corrections after GDP shocks
• ME and RI terms are essentially zero, indicating little to no correction after a shock
• Sales tax:
• Error correction terms are in the range of 0.8 to 1.2 indicating relatively strong corrections
after GDP shocks
• RI has the strongest correction process
10. Policy Implications
• Volatility through the business cycle depends on the state and local portfolio of
revenue sources
• Reliance on property tax revenue produces relative stability and resilience
• Reliance on income taxes produces greater volatility and slower recovery
resilience to shocks
• Reliance on sales tax revenue also produces relative stability and resilience
• Individual state performance depends on the portfolio of revenue sources

14. Conclusions
• State revenue source portfolios have a direct impact on the buoyancy and
resilience of state tax systems
• Evidence indicates that states more heavily reliant on property and sales taxes experience
more stable revenue streams and faster error corrections following GDP shocks
• Evidence also shows that states more heavily reliant on income taxes experience less
stable revenue streams and have slow error correction processes
• If the policy objective is to have a stable revenue stream and a resilient tax
system, this evidence points toward greater reliance on property and sales
taxes
