自由市场又是怎样保证食品不会被“暗中”（如果标明当然另当别论）掺入毒品的呢？既然消费者有购买无毒食品的需求，惟利是图的商人就会提供。在毒品合法化的社会里，毒品无处不在，就象细菌无处不在一样，人们都担心会吃上毒品，就象都担心会吃上细菌一样，所以商人就会以“保证无毒”的良好信誉为生存之道。到时，即便象可乐这类剂量轻微的毒品，商人也会标明其毒性，以备监督、以示忠厚的。

自由市场怎样保证食品卫生

这道理和卫生费用一样。餐厅如果免去消毒的程序，就会节省一笔费用，相当于增加了利润；餐厅如果在食品中掺入毒品，就会增加销量，也会增加利润。这两种方法在逻辑上是等效的。

那么自由市场是怎样保证消费者的健康的呢？既然消费者有对卫生食品的需求，惟利是图的商人就会提供。在自由竞争中，惟有“卫生”的信誉，才能保住顾客——在香格里拉吃饭后拉肚子的机会微乎其微，因为香格里拉是不会为了节省成本而省却消毒程序的。

科斯：我被反垄断法烦透了

科斯（Ronald H. Coase）：“我被反垄断法烦透了。假如价格涨了，法官就说是‘垄断定价’；价格跌了，就说是‘掠夺定价’；价格不变，就说是‘勾结定价’”。(Ronald Coase said he had gotten tired of anti-trust because when the prices went up the judges said it was monopoly, when the prices went down they said it was predatory pricing, and when they stayed the same they said it was tacit collusion. — Source: William Landes, “The Fire of Truth: A Remembrance of Law and Econ at Chicago”, JLE (1981)) 详见这里和这里。

布坎南：我们尚未堕落成随营的娼妓

布坎南（James M. Buchanan）：需求量和价格之间的反向关系，是经济科学的核心命题，它体现了这样的预设，即人类的选择行为足够理性，以致是可以预测的。没有一个物理学家会说“水往上流”，也没有一个自重的经济学家会说“提高最低工资可以增加就业”。这种说法，要是认真地生发下去，将无异于全盘否定了经济学，使其科学含义荡然无存；要是这样，经济学家除了撰写迎合意识形态偏好的文章，就别无可为了。值得庆幸的是，只有一小撮经济学家愿意背弃两个世纪的经济学教诲；我们尚未堕落成一群随营的娼妓（详见这里）。

Becker: Financial Regulations

Gary Becker: The claim that the crisis was due to an insufficient level of regulation is not convincing. For example, commercial banks have been more regulated than most other financial institutions, yet commercial banks performed no better than other classes of financial institutions. At the other extreme, hedge funds have been the least regulated, and on the whole they did better than most others in the financial sector. One major problem with regulations is the regulators themselves. See here.

Why Bailouts and Stimulus Don’t Work

Benjamin Powell at Washington Times: America’s move to act swiftly and boldly misses the point. Bank bailouts and fiscal stimulus bills don’t work because they strive to maintain the status quo. But the status quo is the problem and exactly what needs to be corrected. The U.S. housing bubble drew too many workers and too much capital into construction and related industries. So funding public works projects to keep those companies in business is the wrong solution. See here. (HT: EconLog)
