    科斯:我被反垄断法烦透了

    Posted on Thursday, December 31, 2009 at 6:28 pm

    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 […]

      布坎南:我们尚未堕落成随营的娼妓

      Posted on Thursday, December 31, 2009 at 6:06 am

      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

        Posted on Tuesday, October 20, 2009 at 11:30 pm

        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 […]

          Why Bailouts and Stimulus Don’t Work

          Posted on Monday, October 19, 2009 at 11:55 pm

          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 […]

            周其仁:货币似蜜,最后还是水

            Posted on Monday, October 19, 2009 at 3:43 pm

            周其仁:“货币似水说”的重心在总量,在价格总水平;“货币似蜜说”更关注过程中相对价格改变的影响。不过,也不宜把两说的分歧看得太大。毕竟,弗老领军的货币主义与哈耶克坚守的奥地利学派,有一个共同的出发点,那就是对“法定不可兑现货币”制度,抱有一种理性的怀疑。结合中国经济2004年以来惊心动魄的起伏,先是“结构性过热”从钢铁、水泥、电解铝漫游到众多投资部门,然后是房地产、股市的历史性的上冲与下跌,再到物价总水平的陡起陡落,我们或许可以把把两说合并:货币进入市场,受黏性支配改变相对价格,然后推高物价总水平。是的,货币似蜜,最后还是带黏性之水 (见这里)。

              Lessons from the Great Depression

              Posted on Monday, October 12, 2009 at 6:03 pm

              Christina D. Romer: [T]hough the current recession is unquestionably severe, it pales in comparison with what our parents and grandparents experienced in the 1930s. Last Friday’s employment report showed that unemployment in the United States has reached 8.1%–a terrible number that signifies a devastating tragedy for millions of American families. But, at its worst, unemployment […]

                波斯纳:我是如何成为凯恩斯主义者的

                Posted on Thursday, October 8, 2009 at 3:02 pm

                薛兆丰按:我最近谈到波斯纳关于凯恩斯的评论(见这里)。冯冠军老师花费了大量宝贵时间和精力,将波斯纳的文章翻译出来。感谢冯老师!波斯纳法官写道:《通论》中虽然还有一些有如邪教的思想,掺杂着疑惑,模糊,无所适从,混乱,错误,故弄玄虚,和诸多思路不清之处,但并没有减少此书与我们当前所面临问题的关联性。经济学家们可能忘记了《通论》,在继续前进,但经济学并没有超出它,或者说通过举例说明的非正规讨论方式,可以使数学无法用到的角落和缝隙出现光明。凯恩斯的这部杰作,涉及很多内容,但“过时”与它无缘(见这里)。

                    柴静:应该尊重这样的头脑和灵魂

                    柴静:一个国家是由一个个具体的人构成的,它由这些人创造并决定,只有一个国家能够拥有那些寻求真理的人,能够独立思考的人,能够记录真实的人,能够不计利害为这片土地付出的人,能够捍卫自己宪法权利的人,能够知道世界并不完美,但仍然不言法理、不言放弃的人,只有一个国家拥有这样的头脑和灵魂,我们才能说我们为祖国骄傲,只有国家能够尊重这样的头脑和灵魂,我们才能说我们有信心让明天更好(见这里)。
