Tax Evasion Revised: Surprising Experimental Evidence on the Role of Principal Witness Regulations and Differences in Gender Attitudes

This paper experimentally investigates indirect tax evasion that requires the cooperation of an intermediary. We explore the effectiveness of the introduction of a principal witness regulation as a means to facilitate tax compliance. Reactions show a significant drop in tax compliance that, surprisingly, is vastly different across gender with the effect being mainly driven by women. As a result, women decrease their tax compliance significantly reaching an even lower level than men who in turn do not react to the institutional change.
