This paper presents the new OECD competition law and policies (CLP) indicators which measure the strength and scope of competition regimes in 49 jurisdictions (OECD and non-OECD). The indicators cover areas for which there is a broad consensus among member countries on what constitutes ‘good’ practice for competition regimes. The results suggest that competition regimes are broadly similar across countries in these areas because most countries have adopted all or a large number of the ‘good’ policy settings captured by the indicators. On average, the design of competition laws and policies appears to be closer to best practice in OECD countries than in non-OECD countries. Jurisdictions differ relatively more on the enforcement of competition law than on the competition law itself.
