Randomness in Tax Enforcement

For most parameter values, increased randomness about how much taxable income an auditor would assess leads to higher reported income and more revenue, When reducing randomness is costly, optimality requires some randomness in assessed taxable Income.

These results do not rely on the presence of a distortion in labor supply.
