This article incorporates tax evasion into an optimum taxation framework with individuals di ering in earning abilities and initial wealth.

This paper attempts to estimate the size and distribution of tax evasion in rich countries. We combine random audits—the key source used to study tax evasion so far—with new micro-data leaked from large offshore financial institutions—HSBC Switzerland (“Swiss leaks”) and Mossack Fonseca (“Panama Papers”)—matched to population-wide wealth records in Norway, Sweden, and Denmark. We find that tax ...
