Competition and Welfare Effects of VAT Exemptions
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 effects of such asymmetric VAT regimes on market shares, optimal prices, and tax receipts analytically and by simulation. The analytical model shows how asymmetric VAT exemptions distort competition by strengthening the competitive position of non-rated firms. The net effect of VAT exemptions depends on the fraction of VAT rated inputs versus the fraction of non-rated customers. We further shed light on the main competitive impact of VAT policies, while showing the consequences on overall welfare by presenting simulation results based on a calibrated quantitative model of a selected sector. The contribution of our paper is to provide guidance on how to resolve the policy trade-off between a level playing field, consumer surplus and government tax revenue.
