In order to answer this question, we use a game-theoretic model with Bayesian forecasting to investigate the benefits of cooperative information sharing for the online and traditional retailers. We assume that online and traditional retailers have their own private forecasting information about the market demand (asymmetric information). Our results show that when the online and traditional retailers share their private forecasting information, both retailers will be better off if they have a close forecast. Furthermore, if retailer individual information is less accurate and channel competition is more intense, information sharing becomes much more necessary to each retailer. Based on our results, optimal marketing strategies are derived and important managerial implications are provided. Is information sharing profitable in e-business age?

This study uses the psychometric technique of the fundamental interpersonal relationship orientation-behavior (FIRO-B) to analyse and compare the social interaction preference of certified internal auditors (CIAs) working for US corporations and certified public accountants (CPAs) employed by public accounting firms. Surveys were developed using the FIRO-B instruments and sent to internal auditors from US corporations located in the western and southeastern sections of the USA. The results of the study show that the scores of the two groups are significantly different. Internal auditors reported lower social interaction preferences than the public accountants.

IT as a strategic resource can help bank managers to gain competitive advantage by improving banks' capabilities. The aim of this study is to investigate the impact of IT and two other variables on firm performance considering the moderating role of environmental dynamism and strategy. IT costs, number of employees and fixed assets are considered as independent variables which affect banks' profit and deposit as two main variables of bank performance. The study sample consists of 102 branches of the largest Iranian private bank. Results show that IT costs appear to have a stronger positive impact on bank performance when there are greater environmental changes and more proactive branch strategy. To our knowledge this is the first study considering the moderating role of strategy and environmental dynamism in the bank industry environment.

With the large array of service offerings, telecom providers engage in active advertising of service bundles to attract new as well as retain the existing customers. Focused advertising by personalising the service bundles based on individual customer preferences is a key success factor of such campaigns. This paper proposes the application of a neural network-based decision support model for pattern association using which mixed bundles of such services may be identified, as per customer preferences, so as to induce higher conversion in cross-sales and up-sales. Consumer service preferences can be combined with some standard packages of VAS bundles to personalise the service bundles and these service bundles would be generated dynamically. Identifying and promoting such services identified through pattern association rules will have a direct impact on the overall profitability of the service provider.

Companies are forced to re-evaluate the way they do business in today's highly competitive and global marketplace. Customers are no longer making buying decisions based solely on product quality and price, but are now also demanding high levels of service and flexibility. Therefore, a comprehensive approach for evaluating the suppliers is required. As service and flexibility are qualitative parameters, the aforementioned approach should be based on quality control disciplines. Here, we use control charts as a control tool for the suppliers' performance and Six Sigma criterions for more precise investigations. A 0/1 integer programming approach is applied to identify the optimal set of suppliers in the supply network. The efficiency of the proposed mechanism is presented using numerical illustrations.

Using an ordered-logit model, we study whether student performance and attitudes towards group work and team exams impact future individual performance. Our results suggest that satisfaction with one's group does not translate into better individual performance. We also show that satisfaction with the learning method and perceptions of whether it enhances their interpersonal skills fails to significantly impact performance. We do demonstrate, however, that future scholastic performance can be modelled partially as a function of attitudes and prior performance. Finally, we discuss the implications for educators and practitioners. Does attitude towards one's group impact student performance in a team-exam environment? A longitudinal analysis
