Does competition relate only to firm behavior, or does it also intersect with regulation? In this video, María Pilar Canedo (Academic Director of the OECD-GVH Regional Centre for Competition), Federica Maiorano, and Said Kechida (both Senior Competition Experts at the OECD Competition Division) explore the relationship between competition and regulation. They draw on OECD work on Competition Assessment and its practical toolkit to illustrate key insights.
