This book has uncovered the role of multinational enterprises in the making of the Single European market by uncovering both firm strategies in the new business environment of an internal market as well as firm mobilization against to various dimensions of market governance. Together, the business cases covered in this book add a new, granular perspective to European political economy, not focused on the theoretical framework of capitalism, but on business strategy that constitutes its praxis. They also demonstrated the very different ways multinationals approached market integration and the Commission’s efforts to establish market regulations for the benefit of consumers and workers, with automakers most enthusiastic about the industrial focus of the market’s design, banks more interested in the new opportunities of market enlargement and its regulation than in deeper market integration, and commerce mobilizing against the threats of producer consolidation and the social dimensions of the Single Market.
