Performance hypothesis testing with the Sharpe ratio: The case of hedge funds

As recent research highlights that the Sharpe ratio has a decision theoretic foundation even in the case of asymmetric or fat-tailed excess returns and thus is adequate even for the evaluation of hedge funds, this note provides the first Sharpe ratio based performance analysis of the hedge fund market. Furthermore, it addresses the important practical question whether the choice of hypothesis test used to statistically compare Sharpe ratios can influence an investor’s hedge fund selection process. Our key findings are as follows: (i) Only a small fraction of hedge funds in our large dataset can significantly outperform passive investments in corresponding hedge fund indices. (ii) Especially in the presence of autocorrelated or skewed excess returns, the traditional test of Jobson and Korkie, 1981, Memmel, 2003 tends to overstate the number of significant outperformers and thus provides potentially misleading information for investors. Decision makers are advised to use the bootstrap test of Ledoit and Wolf (2008) allowing robust and more reliable inference.

‘Too Big to Fail and Too Big to Succeed': Accounting and Privatisation in the Prison Service of England and Wales

This paper is concerned with the challenges involved in the transformation of the prison into a performance‐oriented accounting entity. It examines the implication of private sector accounting and consulting expertise in redefining prison values and prison performance, and it discusses the consequences this had for definitions of risk and responsibility. The paper shows how the reforms promoted a systemic decentring of Prison Service accountability. Prison managers and regulators came to be inserted into hierarchies of expertise and credibility shaped by quests for commensuration and auditability. Further, the paper shows how the reform attempts brought about a situation of institutional lock‐in by contributing, as the outgoing HM Chief Inspector of Prisons Anne Owers has put it in 2010, to the creation of an inflated prison system ‘too big to fail, and too big to succeed'.

投资者参与、企业内在价值与IPO抑价——基于中国A股市场的经验证据

本文以中国A股市场为背景,以2009～2010年沪深两市通过IPO募集股权资本的上市公司为样本,探讨了投资者参与程度、企业内在价值与IPO抑价之间的关系。研究发现,在诸多影响因素中,以市盈率衡量的企业内在价值与IPO抑价负相关;以中签率和换手率衡量的投资者参与程度,与IPO抑价正相关。较低的中签率和较高的换手率,代表更高的投资者参与热情,通常会导致更高的IPO抑价。此外,诸如IPO规模和行业特征等其他因素也会对IPO抑价产生影响。
