The United States’ Affordable Care Act, which entered into force this year, contains further variants on the idea of government as a catalyst, including incentives to reward health-care systems that improve outcomes and reduce costs. The incentives have spurred a number of state-level experiments in Medicaid (America’s health-insurance program for the poor) through waivers of the standard rules.
今年生效的美国平价医疗法案（Affordable Care Act）中包括了政府充当催化剂这一思想的后续衍生品，如用奖金激励改善效果、降低成本的新医疗体系。这套激励刺激了许多摈弃标准规则的州级医疗补助计划（Medicaid，面向穷人的全国医保项目）的产生。
