我今天讲的问题是“反思经济学”。也就是说,我要对教科书当中的经济学(主流经济学)提出一些批评。我们知道对于经济学的批评并不新鲜。过去的一个批评是,认为主流经济学美化了市场,因为为了证明市场的有效性,主流经济学家做了很多假设,而这些假设都不现实,不成立。我的批评则刚好相反,我认为现在的主流经济学不是美化了市场,而是丑化了市场。市场的有效运行根本不需要经济学的那些假设。用了这些假设,人们就会用假设的现实性评价市场,这就败坏了市场的名声。经济学的本来面目几年前,世界经历了二战以来最严重的经济危机。这次危机由美国次贷危机引爆,蔓延至整个金融系统和实体经济,席卷全球。危机 The question I am talking about today is “Reflection Economics ”. In other words, I would like to make some criticisms of the economics of textbooks (mainstream economics). We know that criticism of economics is not new. One criticism of the past is that mainstream economics beautifies the market because, in order to prove the effectiveness of the market, mainstream economists make many assumptions that are unrealistic and unrealistic. My criticism is just the opposite, I think the mainstream economics is not to beautify the market, but to demonize the market. The efficient operation of markets does not require economic assumptions. With these assumptions, people use the hypothetical reality to evaluate the market, which spoils the reputation of the market. The Origin of Economics A few years ago, the world experienced the worst economic crisis since World War II. The crisis was detonated by the U.S. subprime mortgage crisis and spread to the entire financial system and real economy, sweeping the globe. crisis
