The Disciplinary Effect of the Single Market on Swedish Firms

In the 1980s it became increasingly clear that the European Community market was still segmented by national borders because of non-tariff barriers to trade. A major objective of the Single Market Program in 1992 was to remove these barriers, thereby enforcing intra-union competition. In this paper, a panel of Swedish firm-level data is used to evaluate whether domestic market power has been curtailed as a consequence of the SMP and of the Swedish membership in the European Union in 1995. Evidence of increased competition emerges, as price-cost margins have declined in industries with high non-tariff barriers prior to 1992.
