Abstract:
When demand is linear, and supply is perfectly elastic, tax revenue is maximized at a per-unit tax that
causes demand elasticity to increase to twice its initial value, plus one. This is termed the 2+1 rule. This
paper shows that the 2+1 rule also applies to classes of nonlinear demand functions, thus justifying the
assumption of demand-function linearity for tax-revenue maximization in these cases. We also
demonstrate that while optimal tax revenue and price elasticity of demand are inversely related, it is not
necessarily best from a tax-revenue maximization perspective to tax the lower elasticity good.
