If tax obligations are met, the balanced-budget substitution of an ad valorem tax on output for a specific tax not only raises a monopolist's production, but also represents a Pareto improvement. However, if tax avoidance or evasion is feasible and the marginal costs of such actions decline with the legal tax burden, a monopolist will respond to a balanced-budget substitution of an ad valorem tax for a specific tax by reducing output, while profits remain constant. Therefore, in the presence of tax avoidance or evasion activities a move towards specific taxation can represent a Pareto improvement.
