Distortions under the value-added tax (VAT) arise mainly from the exemption of specific services and sectors. This paper develops an analytical model that is applicable to any sector characterized by asymmetric VAT exemptions of services and activities or differentiated VAT rates. We analyze the...

The focus of our paper is on the competitive effects of the proposed VAT regime relative to selected alternatives. We also highlight the welfare effects of various VAT scenarios. While an exempt operator cannot reclaim VAT paid on inputs (relevant for non-labor inputs only) and therefore faces...

This paper enhances the defender model by explicitly modeling the cost associated with quality attributes. It considers two firms and two quality attributes which cause fixed and variable cost, respectively, together with the price attribute. Hence, firms compete in three dimensions. The optimal...

Market opening in the postal sector invites competition, but it may also present challenge to financing the universal service obligation (USO) currently in place. USO financing under entry is challenged both by the loss of revenues and scale economies in combination with the affordability...
