A play-the-winner-type urn design with reduced variability

We propose a new adaptive allocation rule, the drop-the-loser, that randomizes subjects in the course of a trial comparing treatments with dichotomous outcomes. The rule tends to assign more patients to better treatments with the same limiting proportion as the randomized play-the-winner rule. The new design has significantly less variable allocation proportion than the randomized play-the-winner rule. Decrease in variability translates into a gain in statistical power. For some values of success probabilities the drop-the-loser rule has a double advantage over conventional equal allocation in that it has better power and assigns more subjects to the better treatment.

专业化管理的家族企业——新加坡的华人企业

通过考察大量口迷历史记录、个人访谈、文献研究及有关新加坡经济、社会的评论，研究了亚洲金融危机（以下简称危机）前后新加坡华人企业变化及其发展的持续性，表明危机前，这些大型企业由家族制管理变为专业化管理；危机后，其变化趋势有两种，一种由于面临着西方企业日益激烈的竞争，在政府密切关注下，同时也因缺乏有能力、有管理家族企业意愿的后代，家族制度已松散；另一种由于没有政府的直接管制，在危机后消极的市场形势下，为谋求生存，任用有能力的家族后代充分发挥优势，维持着传统的家族制。本文分别从市场、制度（包括文化和政府）及一些主要大公司的领导者行为分析，推导一个路径清晰、条脉分明的管理变化模式，同时提出进一步的研究方向——专业化管理家族企业的结构及政府的角色。

What＇s So Special about China＇s Exports？ A Comment

Dani Rodrik argues that China's exports are unusually sophisticated for a country at its income level. He also claims that China's export sophistication reflects the government's successful industrial policy and has been instrumental in the recent acceleration of its economic growth. Although Rodrik's interpretation of China's economic growth is broadly correct, the accuracy of his empirical analysis is questionable. This note identifies several problems regarding the “export sophistication” index used in his empirical work and casts doubt on his analysis.
