Market studies assess whether competition in a market is working efficiently and identify measures to address any issues that are identified. These measures can include recommendations such as proposals for regulatory reform to remove competition restrictions. Market studies also provide a thorough knowledge of the market in question, which can be valuable to better detect antitrust infringements and take more informed decisions. However, they are complex initiatives, which require a good plan and prolonged engagement. Competition experts from several jurisdictions will share their experience on market studies and draw some good practices, also in light of the OECD Market Studies Guide for Competition Authorities.
