Completing the internal market in the European Community. Some industry simulations

This paper studies the effects of changes in the internal market of the European Community in a partial equilibrium model of imperfect competition with economies of scale. The model is numerically calibrated to data on ten industries and the effects of two policy changes are simulated. The first is a reduction in intra-EC trade barriers; the second is the elimination of firms' ability to price discriminate between different national markets. The simple reduction in intra-EC trade barriers generates modest welfare gains, but much more substantial gains are associated with integration of national markets into a single European market.
