Shaking hands with common foes: Clique premium and information diffusion in private equity networks

The fastest growing segment of private equity deals is secondary buyouts (SBOs) sales from one private equity (PE) firm to another. We operationalize a novel FactSet database to map the network structures of secondary buyouts between PE firms. We offer three contributions. First, after controlling for economic covariates, we find that PE firms are almost three times more likely to transact if they share a partner, that is both firms belong to the same clique. Second, we find that the profitability of such transactions is unambiguously higher relative to the baseline only if these are the result of repeated interaction between firms belonging to the same cliques. In other words, a clique premium exists under repeated interaction. Third, we provide evidence that the economic incentive at the core of clique premium may be related to access to information. In fact, we show that information related to transactions diffuses through the network, with 23% and 16% of the information going one and two steps beyond transacting parties, respectively.     

人民币汇率购买力平价的实证检验——基于中国加入SDR后的视角

2005年7月开始的人民币汇率形成机制改革使人民币均衡汇率的确定逐渐具有了市场基础。2015年11月人民币加入SOR对我国汇率市场化程度提出了新要求。在这种背景下，使用2005—2015年数据测算购买力平价理论在我国人民币与其他国家货币双边汇率决定中的有效性，同时测算对购买力平价偏离的半衰期，结果表明：人民币与印度卢比、韩元和南非兰特的双边汇率支持弱购买力平价成立，但半衰期存在差别；强购买力平价没有得到支持。
