Abstract
Advertising, the complexity of products, the struggle of suppliers to remain the most innovativein order to capture consumers and distance themselves from competitors, necessarily impactthe functioning of the market in a positive or negative way. By impacting the market, theyinevitably influence its main players, which are businesses and consumers, the final players inthe market. Economic law is then equipped with an arsenal of sanctions in order to fight againstattacks on free competition and encourage virtuous behavior. These sanctions are very diverseand are notably marked by the presence of positive sanctions, which aim to reward an economicoperator, and negative sanctions, which aim to inflict harm on the defaulting economic operator.They must then satisfy the particular interests of the plaintiff in the action and penalize theperpetrators of the alleged breaches. Are they still effective? The assessment of theeffectiveness of sanctions in economic law reveals a heterogeneous effectiveness of sanctions.The factors necessary for effectiveness will thus be highlighted in order to formulate proposalstending to improve the effectiveness of sanctions in economic law.
