Duncan Presents Tax Incidence In The Presence Of Tax Evasion Today At Indiana

DuncanDenvil Duncan (Indiana-Bloomington) presents Tax Incidence in the Presence of Tax Evasion (with Philipp Doerrenberg (ZEW Mannheim and Institute for the Study of Labor (IZA), Germany) at Indiana-Bloomington today as part of its Tax Policy Colloquium Series hosted by Leandra Lederman:

This paper studies the economic incidence of sales taxes in the presence of tax evasion opportunities. We design a laboratory experiment in which buyers and sellers trade a fictitious good in double auction markets. A per-unit tax is imposed on sellers, and sellers in the treatment group are provided the opportunity to evade the tax whereas sellers in the control group are not. We find that the market equilibrium price in the treatment group is lower than in the control group. This difference is economically and statistically significant, and implies that sellers with access to evasion shift a smaller share of the statutory tax burden onto buyers relative to sellers without tax evasion opportunities.

Interestingly, we find that sellers with evasion opportunities shift the full amount of their effective tax rate onto buyers. Additional experimental treatments show that the full shifting of the effective tax burden is due to the evasion opportunity itself rather than the evasion-induced lower effective tax rate.
