Abstract:
This paper develops and applies a new estimation technique for distinguishing transitory and permanent price and income elasticities of charitable giving using panel data. Twelve-year individual averages of income and deductions are combined with information on legislated changes in tax schedules, to construct instruments for permanent price and income variation. Unlike the previous literature, pre-announced changes in tax law are used to identify transitory variation, and fixed-effects are used to control for unobserved heterogeneity. The timing of giving is found to be significantly more responsive to tax incentives than is the long-run level of giving.
