"Considering the increasing importance of economics in complex cases, the Commission's competition department often makes requests for information asking for substantial economic data (for example used in econometric analysis) during its investigations. Parties also often submit arguments based on complex economic theories on their own initiative. In order to streamline the submission of such economic evidence, the Best Practices on economic evidence outline the criteria which these submissions should fulfill. It also explains the practice of the competition department's case teams and the Chief Economist when interacting with parties which submit economic evidence".
