政府干预、政治关联与企业非效率投资——基于中国上市公司面板数据的实证研究

以2004~2009年间701家上市公司为样本,研究政府干预、政治关联对企业非效率投资行为的影响。研究发现:政府干预一方面会加剧有自由现金流量公司的过度投资,对国有企业过度投资的影响更为严重;另一方面可以有效地缓解融资约束企业的投资不足,尤其是国有企业的投资不足。这说明,出于自身的政策性负担或政治晋升目标,政府会损害或支持所控制的企业,这为政府"掠夺之手理论"和"支持之手理论"提供了实证支持。研究还发现,政治关联与过度投资和投资不足均负相关,这表明,政治关联可以作为法律保护的替代机制来保护企业产权免受政府损害,并为企业谋取利益。     

Effect of ownership structure on underinvestment and overinvestment: empirical evidence from Spain

This paper investigates how ownership affects the investment‐cash flow sensitivity by taking into account the non‐linearities of ownership with respect to firm value, and using a free cash flow index and a criterion for financial constraints to disentangle underinvestment and overinvestment. Interesting results are provided by estimating using the Generalized Method of Moments to eliminate the endogeneity problem. The alignment of interests between owners and managers and the monitoring by concentrated ownership both alleviate the sensitivity of investment to cash flow both in underinvestor and overinvestor firms. However, in the presence of controlling owners, underinvestment and overinvestment are exacerbated.     

Equity financing in a Myers–Majluf framework with private benefits of control

This paper generalizes the Myers and Majluf (1984) model by introducing an agency cost structure based on private benefits of control. This new model predicts that many corporate finance variables each have opposing effects on under- and overinvestment. Private benefits exacerbate overinvestment but, interestingly, a small amount of private benefits can enhance firm value by alleviating underinvestment. Likewise, an increase in insider ownership alleviates overinvestment but aggravates underinvestment. When private benefits are small, the adverse effect of insider ownership on underinvestment tends to dominate. When there are considerable private benefits, the incentive-alignment effect of insider ownership is pronounced. Additionally, this model reconciles existing equity financing theories on announcement effects. It helps resolve the puzzle that small-growth firms do not seem to have an asymmetric information disadvantage when they issue new equity.     

Re-measuring agency costs: The effectiveness of blockholders

This study examines the effectiveness of blockholders in mitigating agency costs such as managerial extravagance, poor asset management and underinvestment. Our evidence suggests that outside and inside blockholders exert their interventions differently. We find that outside blockholders are more vigilant about mitigating managerial extravagance while inside blockholders, especially managerial blockholders, are more effective in improving the efficiency of firm asset utilization. However, only managerial blockholders significantly overcome underinvestment problems, which may be attributable to their duality roles.     

On the macroeconomic effects of establishing tradability in weak property rights

The New Economy is closely associated with computing & communications technology, notably the Internet. We discuss property rights to, and trade in, the difficult-to-define intangible assets increasingly dominating the New Economy, and the possibility of under-investment in these assets. For a realistic analysis we introduce a Schumpeterian market environment (the experimentally organized economy). Weak property rights prevail when the rights to access, use, andtrade in intangible assets cannot be fully exercised. The trade-off between the benefits of open access on the Internet, and the incentive effects of strengthened property rights, depend both on the particular strategy a firm employs to secure property rights, and the protection offered by law. Economic property rights can be strengthened if the originator can find innovative ways to charge for the intangible assets. The extreme complexity of the New Economy and the large number of possible innovative private contract arrangements make it more important to facilitate the use and enforcement of private individualized contracts to protect intellectual property than to rely only on standard patent and copyright law. Enabling law is one proposed solution. Current patent legislation in the US has led to costly litigation processes weakening the position of small firms and individuals in patent disputes. The property rights of such firms and individuals could be strengthened with insurance or arbitration procedures.JEL Classification: D21, D23, D52, D82, H54, K11, K22, K41, L11, L23, M13, O14, O33An earlier version of this paper was presented at the 9th Congress of the International Joseph A.

Does supply network location affect corporate investment efficiency?

Using social network analysis, we compute a firm's network position characteristics and then examine their effects on firm investment efficiency. The results show that both supply network centrality and structural holes have no significant impact on corporate overinvestment but can ease corporate underinvestment by alleviating financial constraints. The specific paths are as follows: a firm that has a high level of centrality or rich structural holes in the supply network is more likely to obtain commercial credit and bank loans; however, supply network position has no significant impact on equity financing.     

The value of cash holdings in hotel firms

Extant research in finance suggests asymmetric information increases the cost of external financing substantially and creates underinvestment problems. While franchising might reduce underinvestment problems, it might exacerbate overinvestment problems in poorly-governed firms. Using combined postulations from both the pecking order theory and the free cash flow theory, this study examines the value of cash holdings in hotel firms and the extent to which franchising, financial constraints, and corporate governance affect this value. The findings suggest that cash can be a curse and a blessing; cash is more valuable for financially constrained firms than for unconstrained firms and less valuable for poorly-governed firms than for well-governed firms. Also, financial constraints have a greater effect on the value of cash holdings than weak corporate governance. Although franchising could solve underinvestment problems, it makes poorly-governed firms more vulnerable to overinvestment. Practical and theoretical implications are discussed within realms of corporate finance and franchising.     

风险投资对上市公司投融资行为影响的实证研究

本文研究风险投资机构对上市公司投融资行为的影响机制和作用效果,结果发现:风险投资的加入不仅可以抑制公司对自由现金流的过度投资,而且可以增加公司的短期有息债务融资和外部权益融资,并在一定程度上缓解因现金流短缺所导致的投资不足问题。进一步研究还发现不同特征的风险投资机构均可起到抑制自由现金流过度投资的作用,但只有高持股比例、高声誉、联合投资或非国有背景的风险投资机构才能够显著地改善外部融资环境,缓解现金短缺公司的投资不足问题。综合本文研究结果,作者认为企业上市后仍然可以利用风险投资机构的监督职能、声誉资源和融资关系网络来解决代理问题和信息不对称问题,进而促进企业投融资行为的规范化和理性化。     

Excess cash holdings and investment: the moderating roles of financial constraints and managerial entrenchment

Our study investigates the relationship between excess cash holdings and investment behaviour under two dimensions of financial constraints and managerial entrenchment, based upon a sample of Taiwanese firms operating in an environment characterized by poor legal protection for investors, with data covering the years 2000–2006. We find that excess cash is significantly correlated with capital expenditure, particularly for firms financially constrained and with severe managerial entrenchment. However, the evidence shows that excess cash is insensitive to R&D expenditure under these two dimensions.     

Acquisitions and shareholders' returns in restaurant firms: The effects of free cash flow,growth opportunities,and franchising

Restaurant firms extensively expand through acquisitions. While acquisitions can be an efficient business strategy, the extant literature presented evidence showing that acquisitions can be value–increasing or –decreasing investments. However, why acquisitions increase or decrease firm value is not clear. Corporate finance and franchising theories collectively suggest that the value of acquisitions may depend on firms’ free cash flow capacities, growth opportunities, and organizational forms. The purpose of this study is to examine the concurrent effects of free cash flows, growth opportunities, and franchising on restaurant firms’ returns from acquisitions. The results showed that firms with high-free cash flows gain lower returns compared to firms with low-free cash flows, suggesting that acquisitions reduce underinvestment problems but also increase overinvestment problems. Franchising firms also gain lower returns compared to non-franchising firms; however, the availability of free cash flows exacerbates overinvestment problems in franchising firms. Theoretical and practical implications are discussed.
