基于前景理论和区间数的商业银行信贷决策研究

在商业银行信贷背景下基于前景理论和区间数的模糊决策方法,模拟了商业银行客户经理的信贷决策行为,前景理论能够解释期望效用理论不能解释的现象,更全面考虑银行贷款客户经理有限理性的特征。而贷款客户经理在信贷决策过程中往往很难对客户风险给出精确的决策信息,在对客户的准则值进行评价时,用区间数等模糊形式来表示决策信息,可以更好地刻画信贷决策问题,帮助银行贷款客户经理提高决策质量。

Public Policy for Venture Capital

This paper proposes a simple partial equilibrium model to investigate the effects of government policy on venture capital backed investments. Giving up an alternative career, entrepreneurs focus their effort on a single, high risk venture each. Venture capitalists acquire an equity stake and offer a base salary as well. In addition to providing incentive compatible equity finance, they support the venture with managerial advice to raise survival chances. We analyze several policy measures addressed at venture capital activity: government spending on entrepreneurial training, subsidies to equipment investment, and output subsidies at the production stage. While these measures stimulate entrepreneurship, only cost-effective government services can improve welfare.     

Taxation and Venture Capital Backed Entrepreneurship

In recent years, venture capital has increasingly become a factor in the financing of new firms. We examine how the value of mature firms determines the incentives of entrepreneurs to start up new firms and of venture capitalists to finance and advise them. We examine how capital gains taxes as well as subsidies to start-up costs of new firms affect venture capital backed entrepreneurship. We also argue that dividend and capital gains taxes on mature firms have important consequences for start-up firms as well.     

Post-IPO Operating Performance, Venture Capital and the Bubble Years

Abstract:  We analyse the post-issue operating performance of 316 venture-backed and 274 non-venture UK IPOs 1985–2003. The finding of a statistically significant five-year, operational decline exhibited over the full sample period is not robust. Rather it is driven by the dramatic underperformance during the 1998–2000 bubble years while IPOs perform normally in the remaining years. Cross-section regression results indicate support for venture capital certification in the non-bubble years but a significantly negative relationship between operating performance and venture capitalist board representation during the bubble years. The bubble year underperformance is explained by market timing and by low quality companies taking advantage of investor sentiment.     

风险投资领域“对赌协议”的可执行性研究

对赌协议在我国风险投资领域已有较多表现,实践中因对赌失败所引发的执行困境时有发生。本文阐明了本土背景下的对赌协议产生基础在于企业的股权融资偏好行为,分析了对赌协议在不完全契约状态下表现出的射幸性特点,论证了基于企业估值调整所进行的条款安排并不违背法律所追求的公平和效率目标。在此基础上,文章认为,对赌协议的可执行问题最终需回归到对其效力的认定上。合法性、契约自由以及公司自治等原则是审视此类协议效力的重要标准。     

Venture Capital and Private Equity: A Review and Synthesis

This paper reviews the existing literature on venture capital and private equity. The paper emphasises the importance of examining venture capital in the light of recent developments in corporate finance and its distinctiveness from other forms of finance. In order to understand current developments, the paper adopts a framework which combines industry/market and firm levels of analysis. Existing literature is reviewed using this framework. Industry level issues relate to rivalry between firms, the power of suppliers and customers, and the threats from new entrants and substitutes. Firm level issues concern deal generation, initial and second screening, valuation and due diligence, deal approval and structuring, post-contractual monitoring, investment realisation, and entrepreneurs' exit and recontracting with venture capitalists. This is followed by a review of the evidence on the performance of venture capital firms. The paper suggests potentially fruitful areas for further research including the extension of analysis to cover all stages of venture capital investment, examination of the inter-linkages between industry and firm level issues and between stages in the venture capital process, as well as further analysis of deal structuring issues and investment realisation and recontracting.     

Asymmetric Information and the Market Structure of the Venture Capital Industry

In this paper we study a horizontally differentiated market for financial intermediation and develop a simple explanation for concentration in the financial intermediation industry. We show that under asymmetric information, if the demand for funds is not perfectly elastic, the heterogeneity of entrepreneurs in need of financing translates into a barrier to entry. That is, we do not need to resort to learning, weak property rights or exogenous costs of entry to generate this result.

Performance of Private to Public MBOs: The Role of Venture Capital

Abstract:   Using a unique dataset, we examine financial performance, and venture capital involvement in 167 MBOs exiting through IPOs (MBO‐IPOs) on the London Stock Exchange, during the period 1964 –1997. VC backed MBOs seem to be more underpriced than MBOs without venture capital backing, based on average value‐weighted returns. MBOs backed by highly reputable VCs tend to be older companies, and exit earlier than MBOs backed by less reputable VCs. The results contradict 'certification' and 'grandstanding' hypotheses supported by US data ( Megginson and Weiss, 1991 ; and Gompers, 1996 , respectively). We found no evidence of either significant underperformance, or that VC backed MBOs perform better than their non‐VC backed counterparts in the long run. However, MBOs backed by highly reputable venture capital firms seem to be better long‐term investments as compared to those backed by less prestigious venture capitalist firms. The results remain robust after using different methods to measure performance, and after controlling for sample selectivity bias.
