In this note we discuss how to treat taxes in a cost-benefit analysis (CBA). In particular we relate the shadow price of taxes in CBA to the concepts the marginal cost of public funds MCPF) and the marginal excess burden (MEB) of taxes. In particular we demonstrate that the MCPF is equal to one...

A central finding of the modern labor market literature is that labor supply responses tend to be concentrated along the extensive margin (labor force participation) rather than the intensive margin (hours of work). Yet, the literature on the marginal cost of public funds (MCF) focuses solely on...

The marginal cost of public funds is usually seen as a number greater than one, reflecting the efficiency cost of distortionary taxes. But economic intuition suggests that since green taxes are efficiency-enhancing the MCF with such taxes will be less than one. The paper demonstrates that this...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...

In this paper we revisit the literature on the economic implications of inefficiency in public services provision. Most authors emphasize the need of changing public sector management practices and the scope of activities carried out by general government. Following Dupuit (1844) and Pigou...

The fact that raising taxes can increase taxed labor supply through income effects is frequently used to justify very much lower measures of the marginal welfare cost of taxes and greater public good provision than indicated by traditional, compensated analyses. We confirm that this difference...

We present analytic formulas for calculating marginal welfare costs when taxes are levied against the wages of a heterogeneous population of households and marginal tax revenue finances either the supply of a public good or lump-sum transfers. The formulas are applied to explain the wide...

This paper shows that under typical conditions the simple "excess-burden triangle" formula substantially underestimates the excess burden of commodity taxes. This formula performs poorly because it ignores general equilibrium interactions - most importantly, interactions between the market for...
