Li–Chen Hsu (Department of Public Finance, National Chengchi University, Taipei, Taiwan) has published Experimental Evidence on Tax Compliance and Voluntary Public Good Provision, 61 Nat’l Tax J. 205 (June 2008).  Here is the abstract:

Existing experimental literature on tax compliance and crowding–out examines either the incentive to evade tax or the incentive to give, but not both. This paper provides an experimental examination of the behavior of tax evasion and voluntary contributions when both publicly and privately provided public goods are present. The experimental evidence suggests that the privately provided public good is a substitute for the publicly provided public good, but the converse does not hold, and that the level of compliance may be underestimated, ceteris paribus, if private contributions are not taken into account.
