The relative efficiency of commodity futures markets

The ability of futures markets to predict subsequent spot prices has been a controversial topic for a number of years. Empirical evidence to date is mixed; for any given market, some studies find evidence of efficiency, others of inefficiency. In part, these apparently conflicting findings reflect differences in the time periods analyzed and the methods chosen for testing. A limitation of existing tests is the classification of markets as either efficient or inefficient with no assessment of the degree to which efficiency is present. This article presents tests for unbiasedness and efficiency across a range of commodity and financial futures markets, using a cointegration methodology, and develops a measure of relative efficiency. In general, the findings suggest that spot and futures prices are cointegrated with a slope coefficient that is close to unity, so that the postulated long-run relationship is accepted. However, there is evidence that the long-run relationship does not hold in the short run; specifically, changes in the spot price are explained by lagged differences in spot and futures prices as well as by the basis. This suggests that market inefficiencies exist in the sense that past information can be used by agents to predict spot price movements. A measure of the relative degree of inefficiency (based on forecast error variances) is then used to compare the performance of different markets. © 1999 John Wiley & Sons, Inc.

Web advertising: The role of e-mail marketing

This study examines a comprehensive range of executional elements in a sample of permission-based e-mail marketing campaigns. The sample comprised almost 1000 promotional e-mails sent over an 18-month period by twenty leading U.K. e-retailers. Content analyses of the e-mail campaigns reveal that different tactics of format, address, subject lines, hyperlinks and interactivity are applied to initially attract customers' attention and then encourage further interest. Interviews with nine of the twenty marketing executives who designed the campaigns pointed to managers' reasons for use of the tactical alternatives.     

Just Doing Business or Doing Just Business: Google,Microsoft, Yahoo! and the Business of Censoring China’s Internet

This paper addresses the criticism recently directed at Internet companies who have chosen to do business in China. Currently, in order to conduct business in China, companies must agree to the Chinese government’s rule of self-censoring any information the government deems inappropriate. We start by explaining how some of these companies have violated the human rights of Chinese citizens to freely trade information. We then analyze whether the justifications and excuses offered by these companies are sufficient to absolve them of moral responsibility. We argue that both justifications and excuses offered are insufficient. Wilfully abiding by unjust laws, albeit necessary to do business in China, should not trump moral actions that protect rights. “This is not something we did enthusiastically, or not something that we are proud of at all.”– Elliot Schrage answering questions from Congress regarding Google’s decision to censor its Internet searches in China Neil Haddow is currently finishing his PhD in philosophy at the University of Waterloo.

Women’s Careers at the Start of the 21st Century: Patterns and Paradoxes

In this article we assess the extant literature on women’s careers appearing in selected career, management and psychology journals from 1990 to the present to determine what is currently known about the state of women’s careers at the dawn of the 21st century. Based on this review, we identify four patterns that cumulatively contribute to the current state of the literature on women’s careers: women’s careers are embedded in women’s larger-life contexts, families and careers are central to women’s lives, women’s career paths reflect a wide range and variety of patterns, and human and social capital are critical factors for women’s careers. We also identify paradoxes that highlight the disconnection between organizational practice and scholarly research associated with each of the identified patterns. Our overall conclusion is that male-defined constructions of work and career success continue to dominate organizational research and practice. We provide direction for a research agenda on women’s careers that addresses the development of integrative career theories relevant for women’s contemporary lives in hopes of providing fresh avenues for conceptualizing career success for women. Propositions are identified for more strongly connecting career scholarship to organizational practice in support of women’s continued career advancement.     

Long memory and structural breaks in commodity futures markets

This study employs daily data for 14 commodities and three financial assets 1990–2009 to explore the impact of the time series properties of the futures‐spot basis and the cost of carry on forward market unbiasedness. The main result is that the basis of 16 assets exhibits both long memory and structural breaks. The long memory in the basis is robust even to the use of break‐adjusted data. It implies that the cost‐of‐carry has long memory which the empirical results confirm using the interest cost as a proxy. These new findings suggest that the forecast error has long memory and are inconsistent with unbiasedness. They could be consistent with a weaker version of market efficiency in the presence of a fractionally integrated, time‐varying risk premium but they could also be rationalized by priced noise trader risk with limits to arbitrage in less than fully efficient markets. © 2010 Wiley Periodicals, Inc.

Lining Up for Star-Wars Tickets: Some Ruminations On Ethics and Economics Based on An Internet Study of Behavior in Queues

Queues may represent business ethics in microcosm: they provide an opportunity to study in a smaller package the fundamental ethical tension in economic activity between self-interest and civility in the context of uncertainty and stress. In May 1999 people began forming lines to purchase tickets to the new Star Wars movie "The Phantom Menace." This paper reviews responses to a questionnaire on the internet regarding experiences in those lines. It focuses on two behaviors threatening queue discipline – the formation of cooperative groups and "pre-scalping." It concludes that although queues are complex phenomena, exhibiting important ethical, economic, social, and psychological elements, the general organizing principle of "first-come-first-served" still provides the foundation for queues while at the same time making room for a variety of legitimate modifications. Second, this paper concludes that, as with queues, the thought that self-interest is the exclusive guiding principle for business behavior is likewise too narrow, inducing participants to neglect opportunities for personal enrichment and satisfaction.     

Scale and scope economies of Australian permanent building societies in a dynamic framework

In this paper we examine the interrelationship between technological change, branching, and the multi-product cost structure of Australian Permanent Building Societies within a dynamic specification of the cost function. The results strongly support this dynamic formulation, though the speed of adjustment of costs to long-run levels is quite fast. We also find evidence of economies of scale for small societies, suggesting some potential for smaller societies to benefit from increased scale through mergers.
