For some entities, the utility-maximizing evasion rate depends substantially on tax audit features, such as audit probabilities and penalty rates. Bergolo et al.

Of all the channels that we explore, recent contact with audits best explains differences in misperceptions.Centro de Estudios Distributivos, Laborales y Sociales
