Private equity performance, both for buyouts and venture capital, has been highly cyclical: periods of high fundraising have been followed by periods of low performance. Despite this seemingly predictable variation, we find modest gains, at best, to pursuing realistic, investable strategies that time capital commitments to private equity. This occurs, in part, because investors can only time their commitments to funds; they cannot time when commitments are called or when investments are exited. There is a high degree of time-series correlation in net cash flows even across commitment strategies that allocate capital in a very different manner over time.  相似文献

Small and medium enterprise (SME) research has typically found that female-owned SMEs underperform male-owned SMEs. Further, this underperformance usually persists after controlling for variables such as industry, age of business, and size of business. However, previous studies have normally limited their assessment of performance to sales or profit (or growth in sales or profit) without controlling for differences in risk. Our results indicate that although profits are significantly higher for male-controlled SMEs, so is the variation in profits (risk). After adjusting for risk, we find no significant difference between the performances of male- and female-controlled SMEs.  相似文献

It seems intuitively obvious that firms in supply chains may have more to gain than to lose from learning to cooperate; but it is now more than two decades since Poirier [1999. Advanced Supply Chain Management. San Francisco, CA: Barrett-Koehler] and others called for cooperation in order to capture mutual gains in supply networks and even now ‘cooperation is neither common nor easy’. The simple fact is that not only are supply chains exceptionally complex but so too is the ‘process of cooperating’ – often in the context of antitrust legislation and competition policy. This paper argues that there is a critical need to rethink the principles and processes of cooperation within the broader framework of the competitive behaviour of firms and business strategy. Particularly, it suggests that the relatively recent thinking of Greenwald and Kahn [2005 Greenwald, B., and J. Kahn. 2005. Competition Demystified A Radically Simplified Approach to Business Strategy. New York, NY: Portfolio, The Penguin Group. [Google Scholar]. Competition Demystified A Radically Simplified Approach to Business Strategy. New York, NY: Portfolio, The Penguin Group] in their ‘radically simplified approach to business strategy’ offers sound conceptual insights into cooperation and cooperative strategies for firms not only in markets but also in chains. Furthermore, it notes that the analytical framework for cooperation and cooperative strategies which the authors develop is far removed from the notion of cooperation as ‘commitment and trust and shared thinking’ and from ‘buyer/seller reciprocity’ and ‘collaborative attitudes’ which tend to underwrite much contemporary thinking and research. The paper also argues that the Greenwald and Kahn framework – its single intelligence model of cooperation and cooperative strategies – resonates with real-world relevance, at least for particular supply chains. The paper focuses attention on research into globally significant export coal chains from major east coast Australian ports and in brief case studies finds substantial alignment between concept and practice.  相似文献

This paper reports the results of a scientific survey of the equity valuation practices of CFA Institute members with equity analysis job responsibilities. Using an instrument designed to minimize biases in prior valuation surveys and sampling a larger group than in previous studies (13,500 investment professionals, resulting in 1,980 valid completed questionnaires), this paper documents professional practices in the selection of equity valuation approaches, including specific model variations and key input preferences. Important differences in practice were observed across geographies and employer firm types.  相似文献

Social TV is the use of communication devices to connect with family and friends watching other TV screens. Plausible arguments suggest both positive and negative effects of social TV viewing on ad-effectiveness. This study contributes by providing evidence for the direction of social TV's effects. The results of a controlled laboratory experiment suggest that the benefits of social TV, principally its association with live TV and therefore less ad-avoidance, come at the cost of negative distraction effects. Like normal coviewing, social TV viewing distracts from ad-processing, reducing unaided recall and brand attitude favorability, compared to individual (solus) viewing. However, social TV messaging about ads improved brand attitude. Perceived creativity increased the likelihood of ad-related messaging. Social TV also has an additional source of distraction, multitasking, but in this study, multitasking did not further reduce ad-effectiveness compared to coviewing. The paper concludes with implications for advertisers and future research.  相似文献

The finance literature seems to be in support of the diversification benefits of adding commodity futures to an existing portfolio. Yet no empirical work has been performed to test whether the benefits are indeed statistically significant. This paper addresses several unresolved issues concerning the potential diversification benefits of commodities. First, we attempt to ascertain whether the alleged diversification benefits exist and are statistically significant. Second, to what extent are the diversification benefits unique to US investors? Would investors of a resource-based economy like Canada also benefit from adding commodities to their portfolios? Third, recent studies indicate that correlations among international equity returns are higher during bear markets than during bull markets. This type of regime-switching correlation behavior will mean lower diversification benefits from international investments when investors face a bearish environment at home. Do commodity futures display the same type of regime-switching behavior? To what extent do commodity futures offer real diversification benefits that are robust over time and across regimes? Finally, commodities may appear to be an asset for the more adventurous investors with higher risk tolerance. We want to know what type of investors should hold commodities. We demonstrate that the diversification benefit of commodities is a far more complex phenomenon than often understood in the finance literature.  相似文献
