2010年由约翰·西格弗莱德（John Siegfried）的《学好经济学，过上美好生活 》 （ Better Living through Economics）强调了这些创新对真实世界的影响：碳排交易、赚得收入（earned-income）税抵扣、降低贸易关税、工作福利（welfare-to-work）计划、高效货币政策、频段执照拍卖、交通部门去监管化、延迟接受算法（deferred-acceptance algorithms ） 、 开明反垄断政策、纯志愿军、巧妙使用默认选项促进退休金储蓄等。
The 2010 book Better Living through Economics, edited by John Siegfried, emphasizes the real-world impact of such innovations: emissions trading, the earned-income tax credit, low trade tariffs, welfare-to-work programs, more effective monetary policy, auctions of spectrum licenses, transport-sector deregulation, deferred-acceptance algorithms, enlightened antitrust policy, an all-volunteer military, and clever use of default options to promote saving for retirement.
