A New Architecture for Personalization Engines: An Open Source Approach

There are many benefits in having personalized engines on a Web site. Several types of architecture have evolved to support this information system. Even though, a recent survey has shown that online shopping behavior is not altered by installing these systems on a Web site, enormous money is being spent on their use. These commercial personalization engines are very expensive to buy and are proprietary in nature. One alternative advocated in this article is to use a new architecture that follows an open source philosophy and uses a situation questions, problem questions, implication questions, need-payoff questions (SPIN) based question-answering strategy to interact with visitors. An implementation (called JESPER, a Jess-enabled personalization system) of such an architecture using JESS (Java-based expert system shell) is also presented. Our experience shows that personalization engines built this way for a Web site can be quite cheap and rigorous.     

Gender and ethnic diversity on boards and corporate information environment

Prior studies argue that demographic diversity on a firm's board impacts its information environment, yet there is limited empirical evidence regarding the relation between board diversity and corporate opacity. We extend this line of research by examining whether gender and ethnic diversity of directors impacts corporate opacity. Using a Herfindahl Index based on directors' gender and ethnicities to measure board diversity, and an opacity index based on analyst following, analyst forecast error, bid–ask spread, and share turnover to measure corporate opacity, we find that board diversity is negatively associated with corporate opacity. Our results are robust to alternative measures of board diversity and the various tests we employ to address potential endogeneity concerns.     

Are pricing policies an impediment to the success of customer solutions?

In an era of declining pricing power and increased global competition, customized solutions appear to be an effective way to build competitive advantages without the debilitating effects of price competition. Solutions involve provision of an integrated combination of goods and services that are designed to meet a business customer's specific needs. Premium prices and higher margins can be extracted by solution providers, who now have considerable incentives to design and market innovative solutions for their customers. We examine the applicability of various pricing frameworks and pricing practices in the context of two industries — business process outsourcing and power generation equipments. Our interviews suggest that firms predominantly use traditional pricing strategies; new strategies for solution pricing are only emerging; and, successful firms are currently using hybrid pricing models. We find that the solutions that we observed among practitioners are not what theory would suggest as true solutions but what would be described by theory as bundled products. We also find that solutions are in the eye of the beholder, i.e., if customers can de-bundle offerings, they are not true solutions. We extend our findings to academic theory and to the practice of developing and pricing solutions.     

Estimation of global systematic risk for securities listed in multiple markets

In this era of rapid globalization of financial markets there has been a substantial increase in cross-listings of stocks in foreign and regional capital markets. As many as a third to a half of the stocks in some major exchanges are foreign listed. The multiple listings of stocks has major implications for the concept of systematic risk. This paper demonstrates that the estimator for systematic risk and the methodology itself changes when stocks are listed in multiple markets. The paper suggests general procedures, using maximum information from the multiple markets, to obtain the estimator of beta under a variety of assumptions about the error terms of the market models in the different capital markets. The assumptions pertain both to the volatilities of the abnormal returns in each market, and to the relationship between the markets.     

Extent of hedging in the US lodging industry

This study investigates the extent of hedging in a sample of lodging firms over a five-year period from 2000–2004. The findings document that lodging firms predominantly use interest rate swaps and options to manage interest rate risk exposure. Lodging firms primarily use these instruments as cash flow hedges of their long-term debt liability. The findings indicate that the hedging decision should be modeled separately using a two-step model. The results are robust to alternative specifications and provide evidence to show financial leverage, floating rate debt, information asymmetry, firm size, cash flow volatility and diversification, to be significantly related to the amount of hedging.     

The Missing Dynamic: Corporations, Individuals and Contracts

In this article we discuss whether it pays to invest ethically. Our aim is to examine corporate social responsibility from philosophical, moral and practical points of views. We focus on two main issues related to ethical investments. Firstly we discuss the moral dilemma of how capitalism has changed its shape in today’s world and from ‘blaming the business’ there is a general attempt to use the markets to promote ethics values and corporate social responsibility. Secondly, we analyze the growth of ethical investment funds in the UK today, and their performance, and highlight some of the institutional investors involved in the management of ethical funds. We discuss whether ethical investments really succeed in reducing the conflict between profit-making and social responsibility as they promise or whether they use commercial rhetoric and market mechanism to merely sell us our own perceived values back. We conclude that the paper has a key contribution in setting the scene for future research in an area that is evolving and of fundamental importance to companies, investors and various stakeholder groups.     

Sale of monopoly information and behavior of rivaling clients: A theoretical perspective

This paper studies a three-stage Bayesian-Cournot game where rivaling firms sign contracts with an information monopoly to purchase proprietary information. The rivaling firms use the external information to create competitive advantage over one another. Knowing the rivalry among its clients, the information monopoly can exploit them by playing one client against another. The information-selling strategy depends on the clients' in-house information technology, the uncertainty of the economic environment, and the number of potential clients. The existence of an information market makes rivaling producers worse off and consumers better off. It is possible that the service of the information monopoly is a private good but a social bad.     

A stochastic cellular automata model of innovation diffusion

A stochastic cellular automata model of new product diffusion is proposed. It is found that the growth for a given market potential can be determined by a parameter that quantifies chance preferences of individuals for the product and can be estimated from field surveys. It is also found that the “takeover time” in a given seed region is almost independent of the number of innovators. The results suggest possible strategies for the successful introduction of a new product.     

Channel evolution: A framework for analysis

This article proposes a comprehensive model for analyzing the environmental forces that affect channel length. The marketing literature regards channel length as a succinct, key measure of channel structure. Transactional cost analysis offers an integrative explanation of the seemingly contradictory phenomena and varied interpretations found in the channels literature. The central thesis of this article is that the developmental process alters the balance between performing channel tasks externally and internally and thereby channel structure. The article also interprets from a transactional cost perspective how selected cultural, political, and urban market concentration factors account for enduring differences in channel structure among nations at similar levels of development.
