Modelling the macroeconomic impact of competition policy : 2023 update and further development

This report models and analyses various aspects of the macroeconomic impact of competition policy interventions by the European Commission over the period 2012-2022. Based on information provided by the Directorate-General for Competition (DG COMP) on its merger interventions, cartel prohibitions and other antitrust interventions, the Joint Research Centre (JRC) has used two models to simulate the macroeconomic impact of such interventions: the QUEST III macro-model of the EU economy, which was developed by the Directorate-General for Economic and Financial Affairs (DG ECFIN) for assessing the impact of EU policies, and an EU-wide input-output model, which allows for an investigation of the sectoral differentiation and spill-over effects of competition policy interventions.
