These key assumptions implies that ad valorem taxes are superior in oligopoly as well as monopolistic competition, showing that earlier results on taxes in monopolistic competition (Schröder in J Econ 83(3):281–292, 2004) are not due to the mode of competition, but rather are due to the functional forms used UR - 10.1007/s00712-012-0320-6 ER -
