Antitrust Reform: An Economic Perspective
从经济学视角审视现有反垄断执法的不满，分析欧美立法改革对消费者福利和经济权力的影响，指出改革需平衡传统原则与风险。
There is widespread dissatisfaction with existing antitrust enforcement. The European Union has enacted comprehensive legislation to address perceived antitrust limitations, and several proposals to amend US antitrust laws have followed its lead. Most of the actual and proposed laws target firms that dominate the digital economy, while others have measures to tighten antitrust enforcement more generally. Market power has increased in the United States and most advanced economies, but it has not been uniformly associated with higher prices or lower productivity. Nonetheless, antitrust reforms can benefit consumers and address concerns about the concentration and exercise of economic power. In the United States, legislation would be desirable to amend rulings that are excessively deferential to antitrust defendants. However, most enacted and proposed reforms include prohibitions or obligations that depart from traditional antitrust principles and create potential risks for consumer welfare.
