Does corporate international diversification destroy value? Evidence from cross-border mergers and acquisitions

This paper investigates the valuation effects of corporate international diversification by examining cross-border mergers and acquisitions of US acquirers over the period 1990–2000. We find that, on average, acquisitions of “fairly valued” foreign business units do not lead to value discounts. In contrast, unrelated cross-border acquisitions result in a significant diversification discount of about 24% after accounting for the valuation of foreign targets. Furthermore, significant wealth gains accrue to foreign target shareholders regardless of the type of acquisition. Overall, our results suggest that international diversification does not destroy value while industrial diversification leads to discounts even after controlling for the pre-acquisition value of the target.

风险分散与中国混合型基本养老保险制度改革研究

本文从参保人养老投资风险分散角度研究混合型基本养老保险制度设计。通过构建一个两期消费模型,综合考虑参保人所面临的人口结构、工资增长率、养老基金投资等风险因素,本文研究了混合型基本养老保险制度中现收现付制与基金积累制的最优比例,并利用中国数据进行了测算与敏感性分析。研究发现:引入小规模个人账户基金积累制可以分散人口老龄化给现收现付制所带来的风险,中国实行混合型基本养老保险制度有其合理性;但如果要维持40%～45%的养老金替代率水平,中国基本养老保险制度的财务可持续性会面临较大挑战。

Rational plunging and the option value of sequential investment: The case of petroleum exploration

The potential to invest sequentially in related assets creates a tradeoff between diversification and concentration. Loading a portfolio with correlated assets has the potential to inflate variance, but also creates information spillovers and real options that may augment total return and mitigate variance. We examine this tradeoff in the context of petroleum exploration. Using a simple model of geological dependence, we show that the value of learning options creates incentives for investors to plunge into dependence; i.e., to assemble portfolios of highly correlated exploration prospects. Risk-neutral and risk-averse investors are distinguished not by the plunging phenomenon, but by the threshold level of dependence that triggers such behavior. Aversion to risk does not imply aversion to dependence. Indeed the potential to plunge should be larger for risk-averse investors than for risk-neutral investors. We test the empirical validity of our theory by examining bidding activity in petroleum lease sales. We find significant plunging behavior across a broad sample of oil companies. We also find that privately-held firms pursue even more concentrated (less diversified) prospect portfolios than publicly-held firms—which we attribute to risk aversion rather than size.     

Antecedents of entry mode choice when diversifying

Corporate diversification is one of the broadest investigation topics in strategic management, but there are important gaps in the literature regarding entry mode choice. Few studies have examined the extent to which pre-entry conditions influence the choice of entry mode into new businesses. Past research has focused exclusively on internal development and acquisition as ways of entering new businesses, without considering the existence of hybrid forms, such as strategic alliances, that have experienced extensive growth during the last decade. Here we present an in-depth analysis of entry mode choice that uses an integrative perspective of corporate diversification and considers strategic alliances as an alternative to traditional approaches. A survey of 272 domestic diversifying entries by 155 Spanish firms allows us to characterize the use of cooperative agreements in diversification and to stress the role of inter-firm cooperation in acquiring the knowledge and capability required to grow into new businesses.

开放式创新背景下新兴企业创新模式对创新绩效的影响

在回顾创新模式现有文献的基础上,以中国821家新兴企业为研究对象,就开放式创新背景下新兴企业创新模式对创新绩效的影响进行研究。得出以下结论：探索式创新和利用式创新均会对新兴企业创新绩效产生积极影响,但新兴企业同时进行探索式创新和利用式创新会对创新绩效的提升产生负向影响;在开放式创新背景下,新兴企业与行业价值链伙伴的垂直联结关系会正向影响企业探索式创新对创新绩效的作用,而负向影响企业利用式创新对创新绩效的作用;市场多元化会正向影响企业探索式创新与创新绩效的关系,而对企业利用式创新与绩效的关系不会产生显著影响。     

Diversification Bias and the Law of One Price: An Experiment on Index Mutual Funds

Individual investors select high-fee index mutual funds despite the fact that the future payouts are nearly identical. The authors offer an explanation for this violation of the law of one price based on investor desire to diversify. While diversification in some settings may be beneficial, in the case of assets with identical payouts, fee minimization is the only rational strategy. The evidence confirms that investors diversify by selecting multiple higher fee funds rather than minimizing fees when investing in index mutual funds.     

家族涉入对企业多元化及其价值效应的影响研究

多元化是战略管理领域中的一个核心议题。文章基于社会情感财富框架和企业行为理论,着重考察了家族涉入对企业多元化战略及其价值效应的影响。基于2010年363家中国民营上市制造业企业样本数据的研究发现：家族所有权对企业总体多元化和非相关多元化均具有显著的负向影响。在多元化的企业价值效应方面,家族管理权会显著减弱总体多元化和非相关多元化对企业绩效的负向影响。这样的研究结果证明了假设猜想：家族通过所有权参与更多影响的是企业的多元化决策,而家族参与管理则会更多地影响多元化战略的执行。这一研究有助于深入揭示家族涉入对企业行为的内在影响机制,有效区分不同维度家族涉入对企业战略决策及执行过程影响机制的差异。
