But these are the benefits of high finance as they apply to the ideal world of economists – that is, a world of rational utilitarian actors who are skilled calculators of expected utility under uncertainty, who are masters of dynamic programming, and who breathe stochastic calculus in their daily life. We do not live in such a world.
但这些都是在经济学家理想王国里，高级金融才能体现的好处。——也就是说每个人都是理性的功利主义者，对不确定性有着精确地计算，可以完全掌握动态的变化，以及在日常生活中可以随机应变地处理问题。事实上，我们并没有生活在这个理想王国里。
