The modern equivalent of that learning about trade policy would be to think about mechanisms to ensure long-term improvement in fiscal policymaking. In particular, it would be helpful to devise a way to identify potential risks to fiscal stability (such as those implied by an over-extended banking and financial system).
时至今日，我们应该借鉴上述贸易政策的政治改良，思考怎样确保财政决策有一个持续改善的长效机制。尤其应该考虑有什么办法可以预警财政稳定性的风险（例如银行业和金融体系过度扩张所带来的风险）。此外，需要限制立法部门的施压能力，避免它们强推一些只有地方意义的项目，产生额外开销干扰整个财政大局。
