This paper incorporates more general cases with a new class of constantly adjusted concavity demand curves and includes three types taxes. To verify the output symmetry under various forms taxation, we simulate both linear constant elasticity functions unit, ad valorem, cost valorem If all in submarkets are linear, total outputs identical uniform pricing third-degree price discrimination. Furth...
