Revenue Diversification: Fiscal Illusion or Flexible Financial Management

This study examines the trends in revenue diversification in approximately 240 suburban municipalities in the Chicago metropolitan region between 1988 and 1997. It then tests a model of revenue diversification's impact on tax effort using data from 1993 to 1997, and separated by home rule and non–home rule municipalities. Trends show that suburbs with higher increases in diversification tend to be home rule, younger, less residential, experiencing more growth, less reliant on property taxes, and more reliant on sales taxes. Model estimates show that communities with more revenue diversification have lower tax effort when controlling for other determinants of tax effort, and this effect is stronger in non–home rule municipalities.
