经济学家讲不讲“道德”问题,说到底就是经济学家在经济研究中要不要价值判断。这个问题在西方经济学界颇富争议性,迄今为止谁也没有说服谁。但在国内学术界,总有一种倾向性的看法:经济学界的自由主义学派是主张经济学家不讲道德的。其中,有的学者在搬出弗里德曼的观点外,还搬出哈耶克作为例子。把哈耶克与弗里德曼都归入经济学界的自由主义行列没有错,但把二人同归为主张经济学家不讲道德的行列,其实是个误会。因为弗里德曼专文论述过经济研究(不是经济学家)原则上应该排除价值判断,而哈耶克则反之。在《通往奴役之路》一书中,尽管哈耶克与弗里德曼一样对自由市场、私有化的维护简直到了无以复加的地步,但哈耶克在经济研究究竟要不要价值判断问题上的看法则十分明确:即经济研究不仅不应该排除价值判断,且经济学家的责任就在于认真探求社 Economists do not speak about “morality”, after all, economists should not value judgments in economic research. This issue is quite controversial in Western economics and so far no one has convinced anyone. However, there is always a tendency in domestic academic circles: the liberal school of economics advocates that economists are unscrupulous. Among them, some scholars moved out of Friedman’s point of view, but also moved out of Hayek as an example. There is nothing wrong with including both Hayek and Friedman in the liberal field of economics, but it is misleading to classify the two as economists unscrupulous. Since Friedman’s essay deals with economic studies (not economists), in principle value judgments should be ruled out, whereas Hayek on the other hand. In the book “The Road to Serfdom,” although Hayek and Friedman maintained their free-market and privatization maintenance to an absolute level, Hayek’s question of whether economic research needs value judgment Is quite clear: economic research should not only exclude value judgments, but economists’ responsibility lies in earnestly exploring the society
