凯恩斯-拉姆齐规则

[Ramsey's 1928 article] is, I think, one of the most remarkable contributions to mathematical economics ever made, both in respect of the intrinsic importance and difficulty of its subject, the power and elegance of the technical methods employed, and the clear purity of illumination with which the writer's mind is felt by the reader to play about it subject. The article is terribly difficult reading for an economist, but it is not difficult to appreciate how scientific and aesthetic qualities are combined in it together.

——John Maynard Keynes, "F.P. Ramsey", Economic Journal, 1930[13]
