In an effort to address the problem, governments in Colombia, Mexico, Peru, South Africa, and elsewhere have been busy changing their tax codes, redesigning their registration systems, and exploring the potentially perverse incentive problems associated with social-welfare programs. While the jury is still out on the effectiveness of any of these initiatives, I would bet against their success.
为了解决问题，哥伦比亚、墨西哥、秘鲁、南非及他国政府忙于修改税法、设计注册系统，及对社会福利计划的不正当激励问题进行研究。虽然相关计划是否有效现在还很难确定，但我打赌计划不会成功。
