Market studies are a versatile tool for competition authorities to analyse whether there are competition problems in a sector, outside the context of a merger review or antitrust investigation. Nearly all competition authorities in the OECD conduct some type of market study. 

While the specific approach and framework for market studies varies across jurisdictions, the experiences of competition authorities provides substantial common insights. 

This document highlights these insights, and summarises the work conducted by the OECD Competition Committee on market studies. It can be used to inform the design of market studies frameworks, and to help guide the execution of market studies. 

This document can be read in conjunction with the International Competition Network Market study good practice handbook.
