Fortunately, the US has the Congressional Budget Office, which scores legislation in terms of its budgetary impact, assesses official budget proposals, and formulates its own economic projections. (I serve on the CBO’s Panel of Economic Advisers, which comments on the draft forecast twice a year, but does not assess budget proposals or anything else.)
美国和其他不少国家所需要的是独立、胜任且经验丰富又不偏不倚的机构。幸运的是，美国还有国会预算办公室，它可以根据预算冲击给立法打分，评估官方预算方案，并给出自己的经济预测。（我便是国会预算办公室经济顾问委员会成员，每年两次对预测草案进行评论，但经济顾问委员会不会评估预算方案或其他事项。）
