Abstract

This paper compares ad valorem and per-unit taxes in a bilateral market where all traders have market power. To do so, we use a simple prototype of strategic market games, namely bilateral oligopoly models, and show that ad valorem taxation welfare-dominates per-unit taxation under strategic bilateral trade. Moreover, ad valorem and per-unit taxes have qualitatively different effects on strategic equilibrium offers.
