The Role of Ethical Standards in the Relationship Between Religious Social Norms and M&A Announcement Returns

Journal of Business Ethics - Prior studies suggest that firms headquartered in areas with strong religious social norms have higher ethical standards. In this study, we examine whether the ethical...     

New insights into the impact of the introduction of futures trading on stock price volatility

We examine whether, and to what extent, the introduction of trading in share futures contracts on individual stocks (i.e., individual share futures, or ISFs) has impacted on the systematic risk and volatility of the underlying shares. The use of ISFs allows a unique experimental design that complements existing work on index futures. Our major findings are as follows. First, we found a general reduction in systematic risk on individual stocks after the listing of futures. Second, we found evidence of a decline in unconditional volatility. Third, we found mixed evidence concerning the impact on conditional volatility. Fourth, the introduction of futures was found to impact on the market dynamics, as reflected by a change in the asymmetric volatility response, although the direction of that change is stock‐specific. In general, the results point to a number of features that are case‐specific and provide new insights into the mixed results that are typical of existing studies. © 2001 John Wiley & Sons, Inc.

What moves the gold market?

In this article, we provide a detailed characterization of the intraday return volatility in gold futures contracts traded on the COMEX division of the New York Mercantile Exchange. The approach allows the study of intraday patterns, interday ARCH effects, and announcement effects in a coherent framework. We show that the intraday patterns exert a profound impact on the dynamics of return volatility. Among the 23 U.S. macroeconomic announcements, we identify employment reports, gross domestic product, consumer price index, and personal income as having the greatest impact. Finally, by appropriately filtering out the intraday patterns, we find that the high‐frequency returns reveal long‐memory volatility dependencies in the gold market, which have important implications on the pricing of long‐term gold options and the determination of optimal hedge ratios. © 2001 John Wiley & Sons, Inc.

New Brands Versus Brand Extensions, Attitudes Versus Choice: Experimental Evidence for Theory and Practice

The current study compares better-fitting and worse-fitting new brand names and brand extensions on brand attitudes and choice shares across situations that differ in terms of the amount of product information available and consumer knowledge of the target product category (which had limited effects), 35[emsp4 ]mm cameras (choice-set competitors Nikon and Minolta). While brand extensions and better-fitting brands generally enjoyed more positive brand attitudes and larger choice shares, effects were moderated by product information. When information was limited to brand name and price, the better-fitting brand extension (Sony) commanded more share than did the better-fitting new brand (Optix) which in turn commanded more share than did either the worse-fitting extension (Nike) or the worse-fitting new brand (Topix). But when information on product features was added, target brands were chosen similarly across brand names where the better-fitting new brand Optix garnered slightly (non-significantly; 5%) more share than the better-fitting extension Sony. This weak preference was reversed, however, in the attitude data where Sony was rated significantly higher in liking than Optix. Two focal conclusions emerge. First, new brands can perform as well as or better than brand extensions when consumers process product information. In this study, brand-extension advantages were confined to situations of limited information processing and better fit. Second, since branding effects differed across attitudes and choice, researchers hoping to duplicate in the laboratory the types of branding effects likely to occur in the marketplace may want to expand their traditional focus on attitudes to include choice.     

The role of contractual governance flexibility in realizing the outcomes of key customer relationships

An entrepreneurial firm's relationships with customers, suppliers, investors, universities, and other organizations have a significant and long-lasting impact on the survival and success of the firm. Yet, little research has focused on how the management of these relationships influences outcomes for entrepreneurial firms.This paper focuses on the customer relationships of new, technology-based firms (NTBFs). We aim to contribute to the literature on the governance of exchange relationships between NTBFs and their customers. Further, in so doing, we seek to explore the implications of such governance for the performance of new firms.Because of their small size, their “liabilities of newness,” and their highly specialized, knowledge-intensive resources, NTBFs are able to maintain only a limited number of close customer relationships. Consequently, NTBFs often become highly dependent on one or a few of their customers. In this study, we focus on the relationships between NTBFs and their single largest customers. We refer to the customer that accounts for the highest proportion of an NTBF's total revenue as the “key customer.”Strategic management literature, resource dependence theory, and transaction cost economics emphasize the risks associated with being dependent on an exchange relationship, focusing on the opportunistic use of power by the exchange partner. These perspectives suggest that firms can minimize their external dependencies and protect themselves against opportunism through the use of contracts. The present paper expands this view by also examining how flexibility in exchange governance may unlock potential benefits or dampen potential dangers that an NTBF faces in its commitment to its single largest customer, e.g., sharing the costs and risks of R&;D with the customer, improving the reputation of the NTBF, and realizing savings in sales and marketing costs. We examine the extent to which the realization of the potential positive and negative outcomes of a high level of dependence are moderated by the flexibility of the exchange partners' attitudes toward contractual agreements. The research question that we seek to answer is: Does the manner in which a contractual agreement is implemented affect the outcomes of a customer relationship for an NTBF at high levels of exchange dependence on the key customer?We develop a set of hypotheses that examines how the governance of the key customer relationship affects the NTBF's new product development, reputation, and sales costs when exchange dependence on the key customer is high. We use the term “contractual governance flexibility” to refer to the extent to which the exchange partners are willing to adjust to changes in the relationship instead of relying on the contract. We test the hypotheses with survey data from 195 NTBFs in the UK. The results of regression analyses reveal that contractual governance flexibility moderates the relationship between exchange dependence and outcomes. In relationships with a high level of exchange dependence, greater contractual governance flexibility was associated with greater new product development and sales cost advantages. No such benefits were realized for relationships in which exchange partners relied heavily on the contract.These findings are important because they suggest that by relaxing formal contractual mechanisms governing a relationship, NTBFs can derive benefits from key customer relationships that are characterized by a high level of dependence. Our findings suggest that at high levels of exchange dependence on key customers, NTBFs can benefit when greater contractual governance flexibility is present. Our data indicated that, interestingly, NTBFs tend to do just the opposite: at higher levels of exchange dependence, NTBFs are inclined to rely increasingly on the contract. By so doing, they may fail to realize the potential benefits of the relationships, such as gaining access to complementary resources and reducing costs. These outcomes, which may be derived from dependent exchange relationships by means of contractual governance flexibility, can have a significant influence on the long-term development and competitive advantage of an entrepreneurial firm.     

Consumer Ethics in the European Union: A Comparison of Northern and Southern Views

There is a growing interest in understanding consumer ethical actions in relation to their dealings with firms. This paper examines whether there are differences between Northern and Southern European Union (EU) consumers' perceptions of ethical consumer behaviour using Muncy and Vitell's (1992) Consumer Ethics Scale (CES). The study samples 962 university students across four Northern EU countries (Germany, Denmark, Scotland, The Netherlands) and four Southern EU countries (Portugal, Spain, Italy, Greece). Some differences are identified between the two samples, which might question the ability of organisations to consider the EU as one homogeneous market.     

Corporate Identity,Ethics and Reputation in Supplier–Buyer Relationships

Multi-national corporations (MNCs) have been criticised for not behaving ethically in some situations, which could have a negative effect on their reputation. This study examines the ethics of a large MNC in its relationship with its suppliers. A brief literature review of corporate identity, business ethics and buyer–supplier relationships is undertaken. The views and perceptions of the buying staff and the suppliers to a large South African MNC are obtained and discussed. The results indicate that this MNC has a good corporate reputation among both its suppliers (an important stakeholder) and its own buying department. The existence and implementation of formal codes of ethics was found to be a necessary, but not sufficient condition for good ethical practice. Candid relationships with suppliers emerged as a second and important factor. Ethical perceptions of buyers by suppliers are driven by the management of corporate identity, through the elements of ethical standards and candid relationships. We present a model of corporate identity/reputation in Buyer–Supplier Relationships. Michael Bendixen is a Professor of Research Methodology and Statistics at the H.

DIFFUSION MODELS FOR EXCHANGE RATES IN A TARGET ZONE

We present two analytically tractable diffusion models for an exchange rate in a target zone. One model generalizes a model proposed by De Jong, Drost, and Werker (2001) to allow asymmetry between the currencies which is often an important feature of data. Estimation of the model parameters by the method of Kessler and Sørensen (1999) using eigenfunctions of the generator is investigated and shown to give well-behaved estimators that are easy to calculate. The method is well suited to the models because the eigenfunctions are known so that explicit estimating functions are obtained, and because the state space is a finite interval, for which it is known that the method can be made arbitrarily efficient by including sufficiently many eigenfunctions. The model fits data on exchange rates in the European Monetary System well. In particular, the asymmetry parameter is significantly different from zero for three out of four currencies. An alternative diffusion model is presented with similarly nice properties, but with different dynamics that allow constant volatility near the boundaries of the target zone. No-arbitrage pricing of derivative assets is considered, and the effect of realignments is briefly discussed.     

Die Privatisierung öffentlicher Wohnungen

Seit 1997 wurden rund 700 000 Wohnungen aus ?ffentlicher Hand privatisiert. Welche Auswirkungen hat diese Ma?nahme auf den Wohnungsmarkt? Ist es aus sozialpolitischen Gründen notwendig, dass Wohnungen in ?ffentlichem Besitz verbleiben? Kann die sozialpolitische Komponente auch mithilfe von Belegungsrechten gel?st werden?

Why sales reps should welcome information technology: Measuring the impact of CRM-based IT on sales effectiveness

This study seeks to answer the following question: Can sales representatives enhance their performance through their acceptance of information technology (IT) tools? Using data collected from two companies, we show that despite uncertain results and the frequent resistance among salespeople to IT interventions, IT acceptance indeed has a positive effect on sales performance. This occurs because salespeople using IT expand their knowledge and, in turn, gain improved targeting abilities, enhanced presentation skills, and increased call productivity. Thus, sales representatives have a strong incentive to accept IT because doing so is likely to sharpen their own job performance.
