Evidence from a Real-Effort Experiment with Real Goods}, year={2010}, month={Aug}, institution={Institute of Labor Economics (IZA)}, address={Bonn}, type={IZA Discussion Paper}, number={5145}, url={https://www.iza.org/publications/dp5145}, abstract={The public finance literature demonstrates the equivalence between consumption and labor-income (wage) taxes. We introduce an experimental paradigm in which individuals make real labor-leisure choices and spend their earned income on real goods. We use this paradigm to test whether a labor-income tax and an equivalent consumption tax lead to identical labor-leisure allocations. Despite controlling for subjects’ work ability and inherent labor-leisure preferences and disallowing saving, subjects reduce their labor supply significantly more in response to an income tax than to an equivalent consumption tax. We discuss the economic implications of a policy shift to a consumption tax.}, keywords={experimental economics;tax equivalence;income tax;consumption tax;behavioral economics}, }
