This book uses a computable general equilibrium framework to evaluate recent value-added tax reform proposals in the European Union from a welfare point of view. The individual chapters deal with the development of value-added taxation in Europe, the main institutional features of different international taxation principles for value-added taxation, tax distortions under the destination and the origin principle, the exchange rate argument, the construction of a computable general equilibrium model and numerical estimates and economic explanations of the welfare effects of value-added tax reforms.
