Steady State Laffer Curve with the Underground Economy

The Laffer curve for high incomes

An expression for the La er curve for high incomes is derived, assuming a constant Pareto parameter and elasticity of taxable income. The peak of this La er curve is given by the well-known Saez (2001) expression. Microsimulations using Swedish population data show that the simulated curve matches the theoretically derived La er curve well, suggesting that the analytical expression is not too m...
