The adaptive markets hypothesis posits that trading strategies evolve as traders adapt their behavior to changing circumstances. This paper studies the evolution of trading strategies for a hypothetical trader who chooses portfolios from foreign exchange (forex) technical rules in major and emerging markets, the carry trade, and US equities. The results show that a backtesting procedure to choose optimal portfolios improves upon the performance of nonadaptive rules. We also find that forex trading alone dramatically outperforms the S&P 500, with much larger Sharpe ratios over the whole sample, but there is little gain to coordinating forex and equity strategies, which explains why practitioners consider these tools separately. Forex trading returns dip significantly in the 1990s but recover by the end of the decade and have been markedly superior to an equity position since 1998. Overall, trading rule returns still exist in forex markets—with substantial stability in the types of rules—though they have migrated to emerging markets to a considerable degree.  相似文献

The empirical corporate finance literature claims that better corporate governance constrains earnings management, while others argue that the unique legal and reporting structure of REITs may reduce the need for such internal corporate governance. Using a sample of publicly traded REITs for the 2004–2008 time period, we examine the relationships amongst corporate governance, accruals earnings management, manipulation of Funds from Operations (FFO), and real earnings management. We find that corporate governance quality is unrelated to accruals earnings management and manipulation of FFO. At first glance, the findings suggest that managers need less internal oversight because of the more transparent reporting structure of REITs. However, we document that REITs engage in significant real activities manipulation for earnings management purposes. Our empirical findings further show that corporate governance characteristics, in particular board size, independence, number of board meetings and audit committee financial expertise, are essential for constraining such activities. Finally, by focusing on a subset of REITs that act in ways which previous research has identified as more susceptible to earnings management activities, we demonstrate that good corporate governance effectively reduces accruals earnings management and manipulation of FFO for these REITs. Overall, our findings indicate that, despite the unique legal and reporting structure, REITs engage in certain forms of earnings management, and that the ability for REITs to manipulate earnings is reduced when corporate governance is more effective.  相似文献

Not having access to mainstream financial services, such as a bank account or a credit card, can lead to a variety of social and economic exclusions. In a number of countries, particularly Ireland, Spain, Canada and the UK, credit unions— member-owned financial co-operatives—play a significant role in reaching under-served and excluded communities, as well as providing ‘safe’ avenues for savings and credit. Yet many credit unions are facing financial and operational problems. This article looks at the experience of Welsh credit unions. The research has implications for policy development and government–credit union relations in Wales and further research on credit unions and financial inclusion.  相似文献

A number of empirical studies have examined business ethics across cultures, focusing primarily on differences in ethical profiles between cultures and groups. When managers consider whether or not to develop a business relationship with those from a different culture, their decision may be affected by actual differences in ethical profiles, but potentially even more so by their perceptions of ethicality in the counterpart culture. The latter issue has been largely ignored in extant empirical research regarding cross-cultural ethical profiles. In this study, we employ a design that allows for a more complete analysis of cross-cultural perspectives, examining both the manner in which selected cultures view themselves and the manner in which those same cultures perceive the ethical profiles of others. To this end, we surveyed master’s students in business fields at several universities in the United States and China—two countries/cultures that engage in a significant amount of business transactions—and examined differences in personal ethical profiles across cultures, differences in one group’s ethical profile and the way it is perceived by the other group, and differences in perceived ethical profiles across cultures; that is, differences in how groups view each other. Findings suggest meaningful discrepancies in the ethical perceptions formed toward the counterpart culture. Results support a role for ethical perceptions in future research, and further examination and inquiry into the development and adaptation of ethical perceptions in cross-cultural business dealings.  相似文献

This article examines the impact of local knowledge spillovers on employment growth in the service sector at both the theoretical and empirical level. It is argued that, in addition to life cycle and tradability effects, spillovers in services are likely to be strongly influenced by distinctive service characteristics and labour-related factors, which impact on the channels through which spillovers are transmitted. Empirical models of employment growth suggest significant differences in spillover effects between industry and services and across public, private, business and personal services. In particular, many services appear to benefit from spillovers arising from a diverse local economy.  相似文献

This paper studies the link between jobs mismatch and the impact of information technologies (ITs) on the efficiency of small service firms. From the perspective of job matching theory, the paper explores how small service firms that use ITs obtain an optimal matching between new skill requirements and workforce skills. The hypotheses suggest that optimal equilibrium will be obtained by matching IT intensity to ITs training and the proportion of workers with high educational levels. The study tests the hypotheses on a large sample of small services firms in Spain. The results confirm that matching the educational levels of the workforce with the IT intensity of the firm increases the efficiency of small service firms, while mismatch will decrease it. The contribution of IT training to firms' efficiency depends on training intensity but not on IT intensity.  相似文献

Changes within the air transport sector have required many European airports to either develop or expand their commercial activities. Strategies have included the expansion of retail space, a broadening of the tenant and merchandise mix and the development of a passenger segmentation strategy. This paper explores the efficacy of this approach by identifying the behaviour of different passenger segments while in an international airport. Using a framework of strategic market segmentation, it identifies how travellers allocate their time having entered ‘airside’ and details any purchases made. Using observational research and a face-to-face quantitative survey, 301 passengers were tracked and interviewed. Through a broad based, a priori form of segmentation, significant differences in shopping behaviour are identified. Such findings assist with the development of the airport's commercial strategy and allow a number of observations to be made about the value of market segmentation from both a theoretical and managerial perspective.  相似文献

The purpose of this study is to explain which factors affect the market orientation of semi-public service organizations in their transition from public to private. Change capacity and interdepartmental and organizational system factors are hypothesized to affect market orientation, which is operationalized in behavioural and cultural dimensions. Results of a survey among top-level executives of Dutch housing associations show that interdepartmental and organizational system factors have a significant effect. The most important antecedents, however, are two change capacity factors: process improvement control and top management emphasis. This suggests that change capacity is crucial for understanding market orientation in many service industries.  相似文献

In this article, we present the results of a case study of an entrepreneur who successfully founded and grew a venture underpinned by a portfolio of strongly homophilous, dyadic ties. Building on our case, we discuss how the entrepreneur strategically constructed these ties through a form of narrative identity work, explore the shared identity narratives that he used to do so, and highlight the heterogeneous nature of the resulting tie portfolio. We go on to explore the factors that motivated the entrepreneur to purposefully construct an entrepreneurial tie portfolio in this way. Building on our findings, we discuss the nature of narrative identity work and its role in creating homophilous ties, explore the connection between the resulting shared identity narratives and trust, and discuss the central role of values in strategic homophily.  相似文献

Abstract

This paper explores the social dynamics by means of which market forces are enacted at the level of everyday consumption. In particular, it draws on Holt's (2002 Holt, D.B. 2002. Why do brands cause trouble? A dialectical theory of consumer culture and branding. Journal of Consumer Research, 29: 7090. [Crossref], [Web of Science ®] [Google Scholar]) notion that as ‘unruly bricoleurs’, consumers kick-start processes of market adjustment and innovation through improvising ways to negotiate the demands of daily life. In this way, consumers can become active players in realising new possibilities for identity construction and empowerment that involve the creative re-appropriation of marketer-based meaning. To investigate those issues, we turn to a virtual community in the empirical setting of car customisation. Over an eight-month period, an internet-based methodology generated textual observations of online posting activity on five internet newsgroups attracting those interested in the particular pursuit of car modification. Participants used those web-forums to share information, passions, and enthusiasms. Analysis shows that grounded aesthetics function as vehicles for creativity and the reworking of dominant market logics (Vargo & Lusch, 2004 Vargo, S.L. and Lusch, R.F. 2004. Evolving to a new dominant logic for marketing. Journal of Marketing, 68: 118. [Crossref], [Web of Science ®] [Google Scholar]). We conclude that online discussion threads offer valuable access to the emergent interplay of discursive resources in circulation among virtual communities and that this has implications for the conduct of environmental scanning. The paper illustrates how the discursive resource-base is nurtured, sustained, and transformed through various interpellations, including performing claims to prestige and self-defining distinctions, as well as constructing narratives of personal history and social dynamics.  相似文献
