我国证券投资基金羊群行为的实证研究

国外的研究显示，发达国家市场机构投资者的羊群行为并不十分明显。作为新兴市场主体的中国机构投资者在这方面的行为特征如何呢？本文使用经典的LSV方法以及Wermers扩展方法，对我国金融市场上以证券投资基金为代表的机构投资者交易行为进行了实证研究。结果发现，我国证券投资基金之间具有较明显的羊群行为，并具有以下特点：同时使用正负反馈操作策略；在流通盘较大和较小的股票上的羊群行为显著；成长型基金的羊群行为显著等。针对这些发现，笔者探究了羊群行为产生的原因，并提出了一些避免过度羊群行为的措施．     

Staging of Venture Financing, Investor Opportunism and Patent Law

Abstract:  Stage financing provides a real option that is valuable when facing external uncertainty. However, it may also induce investor hold-up, if the property rights on an invention are not sufficiently protected. As a consequence, the entrepreneur may not work hard. Investor opportunism is less likely to occur, if investors' residual cash-flow-rights are contingent on verifiable 'milestones' in the previous stage. Equity-linked financing also provides high-powered incentives to the investor not to 'steal the idea' because his payoff becomes sensitive to the project value. The paper provides a new explanation for both types of contractual provisions.

Convergence of Real Capital Market Interest Rates—Evidence from Inflation Indexed Bonds

This paper investigates the convergence of long‐term ex ante real interest rates (RIRs) obtained from Canadian, French, UK, and U.S. inflation indexed government bonds. In contrast to previous research, our evidence suggests full convergence in the long run and, hence, capital market integration. For the same sample period, global convergence is rejected for RIRs measured in conventional terms. From these results, we conclude that previous tests of the long‐run real interest rate parity might have suffered from weak measurement of real capital market interest rates.     

Regulatory Uncertainty and Financial Contagion: Evidence from the Hybrid Capital Securities Market

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids.
