Most route choice models assume that people are completely rational. Recently, regret theory has attracted researchers’ attentions because of its power to depict real travel behavior. This paper proposes a multiclass stochastic user equilibrium assignment model by using regret theory. All users are differentiated by their own regret aversion. The route travel disutility for users of each class is defined as a linear combination of the travel time and anticipated regret. The proposed model is formulated as a variational inequality problem and solved by using the self-regulated averaging method. The numerical results show that users’ regret aversion indeed influences their route choice behavior and that users with high regret aversion are more inclined to change route choice when the traffic congestion degree varies. 相似文献

Evaluation of subsidiary marketing performance: combining process and outcome performance metrics 总被引:1,自引:0,他引:1

Issues in evaluating marketing performance and devising appropriate metrics for measurement have taken center stage in marketing
thought and practice in recent years. We propose an empirical model that enables a multinational enterprise (MNE) to assess
the marketing performance of its subsidiaries, taking into explicit consideration the fact that tactical actions by subsidiaries
contribute to the creation of assets that can be harnessed for marketing outcomes. Thus, our model captures the asset creation
abilities of marketing expenditures and also takes in to account the environmental differences of the context in which each
MNE subsidiary operates. We evaluate comparative, overall, and process-level (creation of market assets and market yield)
marketing performance in the context of multi-country operations. This simultaneous examination of marketing process and marketing
outcome performance enables a global corporation to gain strategic, operational, and diagnostic insights into the performance
of its subsidiaries. Our approach is empirically illustrated with an evaluation of the marketing performance of subsidiaries
of a large global corporation. 相似文献

This paper carries on the recent work of Yang and Wang (2011) on tradable credit schemes by considering heterogeneous users with different value of time (VOT). Given a tradable credit scheme, the user equilibrium (UE) and market equilibrium (ME) conditions with heterogeneous users are formulated into a variational inequalities (VI) problem. Sufficient conditions for uniqueness of the aggregate UE link flows and then the ME credit price are established. Appropriate tradable credit schemes are developed to decentralize system optimal and Pareto-improving network flow patterns. Extension is made to the elastic demand case. 相似文献

Idea Competitions (ICs) are becoming a popular mechanism chosen by firms to perform Open Innovation. They are a way to engage with external sources of knowledge such as individual entrepreneurs and small firms who are asked to submit ideas and compete for a prize. However, little is known about the success of ICs as acquisition mechanisms. The researchers conducted interviews in five multinational companies to evaluate the effects of using ICs as an acquisition mechanism. Although still preliminary, the results of this study show that the success of ICs as an acquisition mechanism remains uncertain because their output (i.e. the number of ideas acquired) is often low compared to the input (i.e. the number of ideas submitted) and effort required to run them (e.g. to vet ideas). Across the cases observed, ICs appear to be more successful at identifying and acquiring early-stage ideas, particularly those outside the current business focus. The study shows that ICs deliver other functional benefits such as improved intelligence and public relations and that these need to be considered as part of the evaluation of the IC's success. The paper concludes by discussing the conditions in which ICs are implemented and the implications for Open Innovation theory. 相似文献

This study focuses on what drives technology-driven companies to engage in risk-taking behavior by serving new markets. Building on the behavioral theory of the firm and prospect theory, this study suggests that technology-driven organizations tend to respond to past performance rather than future possibilities. Using a sample of 5312 video games from 362 game developers, the results reveal that market performance trend and market performance variability have opposing effects on risk-taking behavior: while a positive market performance trend negatively influences a company's tendency to venture into new markets, a high-degree of market performance variability tends to positively influence new market entry. The study also finds opposite results for expert performance trend and expert performance variability: companies with consistently positive expert evaluations are more likely to enter into new markets, while variability in expert evaluations has a negative effect on new market entry. Furthermore, the effects of expert performance trend and variability are conditional on market performance trends. Finally, the results suggest that companies that venture into new markets tend to choose relatively similar markets if these companies are suffering from a negative market performance trend or a negative expert review trend. 相似文献

We study the effects of organizational code‐preserving and code‐violating changes on external evaluations by third parties—an essential but under‐studied strategic outcome. We define code‐preserving changes as a variation in the firm's product range that preserves the social code within which the firm positions its offering. By contrast, a code‐violating change corresponds to a variation in the product range that breaks with past codes and embraces another social code. Our analyses of French haute cuisine restaurants show that code‐preserving changes and code‐violating changes have positive effects on external evaluations. Both effects decline with prior evaluations received by the organization, but only the effect of code‐violating changes is reduced with age. Moreover, external evaluations improve when restaurants undertake more code‐preserving changes than their direct competitors but decline when they make more code‐violating changes than competitors. These results enable us to derive implications for research on strategic change, strategic groups, and strategic social positioning. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

This paper investigates the relationship between mandatory adoption of mobile information technology and market performance in the business-to-business (B2B) setting. This study presents and tests the B2B technology satisfaction model (TSM), including perceived loss of control as the mandatory technology acceptance-specific variable. The results of this study reveal that integrating perceived loss of control with user satisfaction and the TAM (technology acceptance model) in a single model can better explain the B2B market performance model. The empirical results suggest that perceived loss of control has a negative effect on user satisfaction and perceived market performance is influenced by user satisfaction and perceived usefulness. Managerial implications of the study are discussed. 相似文献
