International mutual funds allow individual investors to diversify abroad at a reasonable cost. This paper tests whether international funds that actively engage in country and security selection outperform passive global benchmarks. We apply a mean-variance efficiency test that incorporates the practical prohibition against short sales of open-end mutual funds. Our tests reject the efficiency of the world equity market portfolio over the sample period, and our funds as a group outperform the inefficient world index. However, we find no evidence of security selectivity ability using a 12-country benchmark. We do find that active international funds provide global diversification benefits. Tests using the Positive Period Weight (PPW) measure of Grinblatt and Titman (1989), which is robust to nonlinearity in fund and benchmark returns, yield similar results.  相似文献

We examine the acquisition and joint venture strategies of U.S. banks from 1980 to 1998 to diversify into non-banking sectors. We find that the market responds favorably to both types of expansions, with the gains being shared between acquiring banks and their targets and venture banks and their non-bank partners, respectively. Acquisitions expose acquiring banks to significant increases in nonsystematic, market, and total risk, while joint ventures result in significant decreases in the nonsystematic and total risk measures for participating banks. Our results suggest that product-market expansions, in general, provide U.S. banks with value-enhancing opportunities, and that joint ventures may improve both the return and risk characteristics of the partner banks.  相似文献

This paper reviews what has been learned from experiences of African agriculture and hence what policy lessons may be. Views of African agriculture over the last 130 years have changed from optimism to pessimism and at least halfway back again as the performance of the sector has fluctuated. Fortunately it seems the deep pessimism about agricultural prospects expressed in the 1980s and 1990s has receded. The performance of African agriculture since 1990 suggests that neither those who doubt that any significant advances are taking place, nor those who see advances in some remarkable but perhaps isolated cases of rapid transformation of farming and agricultural supply chains, have sufficient evidence – either from national data or small‐scale studies – to support their positions. Hence policy has to rely largely on general principles and historic lessons, rather than more clearly proven propositions. Policy debates over African agricultural development may sharply divide on some topics, but there is little debate over the importance of basic conditions for agricultural development of an enabling investment climate and the provision of rural public goods. Beyond these basics, the challenge is to remedy the failings of markets that deny most smallholders access to inputs, financial services and insurance. Here opinion divides between whether to return to public provision, as with fertiliser subsidies, or whether private and collective institutional innovations will be sufficient. Recent initiatives to test and scale up the latter look promising, but most have yet to be evaluated. If agricultural development is first and foremost about establishing the basic conditions for growth, then most countries in Africa may be better placed than they have been in the past. Given the many examples that show African smallholders investing and innovating when they have the chance, then there are reasons to hope that the modest growth of production and productivity seen in the last two decades may accelerate in the future – thereby allowing African countries to make the transition from agrarian to urban economies.  相似文献

We examine why firms use nonlinear derivatives (e.g., options). Our results suggest that option characteristics in investment opportunities and debt, the payoff structure of incentive compensation, and free cash‐flow agency problems influence the firm's choice. Investment opportunities, internally generated cash flow, business risk, and option compensation positively influence the use of nonlinear currency derivatives. Option feature in bonds positively influence the use of nonlinear interest rate derivatives, whereas bonus and stock compensation, and CEO tenure have a negative influence. In sum, nonlinear cash flow characteristics in investment opportunity, debt, and executive compensation all relate positively to nonlinear derivative usage.  相似文献

Previous research has shown that a touch or haptic element attached to a persuasive appeal can increase persuasion, particularly for individuals who have a clear preference for touch to enjoy its sensory feedback (high autotelics). This research extends previous work by including involvement in the context of an appeal by a nonprofit. We find, in an experiment where we manipulate involvement, that when a haptic element is present, high autotelics are more persuaded regardless of their involvement with the message. However, for low autotelics, a haptic element increases persuasion under conditions of low versus high involvement with the message. A second experiment measures involvement and finds that again, under low involvement conditions, both high and low autotelics are persuaded by a touch element. Finally, a field study with a local symphony orchestra is conducted in which involvement with the message is low but involvement with the company is high. In this case, a touch element is only persuasive for high autotelics. © 2011 Wiley Periodicals, Inc.  相似文献

At the center of Schumpeter's theory of competitive behavior is the assertion that competitive advantage will become increasingly more difficult to sustain in a wide range of industries. More recently, this assertion has resurfaced in the notion of hypercompetition. This research examines two large longitudinal samples of firms to discover which industries, if any, exhibit performance that is consonant with Schumpeterian theory and the assertions of hypercompetition. We find support for the argument that over time competitive advantage has become significantly harder to sustain and, further, that the phenomenon is limited neither to high‐technology industries nor to manufacturing industries but is seen across a broad range of industries. We also find evidence that sustained competitive advantage is increasingly a matter not of a single advantage maintained over time but more a matter of concatenating over time a sequence of advantages.

In this paper prior work on earnings-price (E/P) and standardized unexpected earnings (SUE) anomalies is re-examined and extended. A relation between excess returns and E/P is tested controlling for SUE. Results suggest that both anomalies are still present in the data, and that the E/P effect exists independently of the most recent earnings surprise.  相似文献

The Impact of Membership in the Ethics Officer Association   总被引:1,自引:0,他引:1  
In this study, we propose considering membership in the Ethics Officer Association (EOA) as a proxy for the firm's commitment to ethical decision making, and we analyze the influence of firm- and CEO-specific characteristics on this commitment. While we observe a positive relationship between membership and firm size, we also document a negative relationship between EOA membership and the executive's time in position and, to a more modest extent, accounting returns. Pursuing this further, we present evidence that firms with past legal issues may seek EOA membership as a signal of their intention to be compliant in the future.  相似文献
