Statutory Incidence of Ad Valorem Taxes: Revisiting Classical Theory and Policy Implications
with Lukas Rodrian
SSRN WP 5232926 (November 2025)
Materials: graphs / files

Abstract

This paper revisits the canonical result that statutory tax incidence is theoretically irrelevant for economic outcomes in competitive equilibrium. We show that statutory incidence of ad valorem taxes changes the tax base and therefore effective tax rates. Shifting statutory incidence toward the demand side reduces the consumer price, raises the supplier price, and increases quantity. The effect on tax revenue is ambiguous. We derive empirically tractable incidence formulas and quantify them using simulations. Applying the framework to OECD payroll taxes, we find that accounting for statutory incidence is important since employer shares rise with total payroll taxes, offsetting nominal differences.

Financing Transitions across Development Stages

My work on development transition finance includes the OECD Transition Finance Toolkit. This toolkit allows analysts and decision-makers to conduct a transition finance diagnostic using a wealth of socio-economic and financial development indicators.
