We use firm-level data for France and Italy to explore the impact of service regulation
reform implemented in the two countries on the mark-up and eventually on the performance of firms between the second half of the 1990s and 2007. We find that the relation between entry barriers and productivity is negative and is crucially intermediated through the firm’s mark up. If both countries adopted OECD’s best practices in terms of entry barriers, their TFP level would increase by 3% for Italy and 3.5% for France.
