The purpose of this paper is threefold: (1) to identify gaps in the literature and inconsistencies between empirical data and Rogers' diffusion of innovations model originally outlined in 1962; (2) to propose a model of fashion adoption; and (3) to conduct an empirical test of the proposed model. The proposed model varies from Rogers' model as follows: four (vs. five) ideal‐type adopter groups with unique names and clear operational definitions; proportional distribution of consumers among groups; clear method of statistically identifying group members; categorization based on fashion innovativeness and opinion leadership; and standard procedure for identifying groups based on mean and standard deviation. The proposed model offers greater precision and provides results that are comparable across studies. The model was analyzed empirically using four methods of categorizing participants into fashion adoption groups (independent variable) and fashion involvement as the dependent variable. Participants in the study were 309 students from two universities. The analysis using the proposed model provided clear‐cut results that supported the hypothesis that higher levels of consumers' fashion involvement increased the probability of earlier adoption. Results from the other three analyses were not as clear‐cut. Based on the model for fashion adoption presented in this paper, the foundation is primed for development of a theory of fashion adoption. The proposed model offers a solution to the problem of identifying fashion adoption groups, plus, the solution achieves the desired effect with the simplest effort and is undertaken with appropriate methods.  相似文献

Customers' perceptions of price differ in the online environment due to the presence of price comparison sites. The purpose of this study is to examine how price comparison sites affect price and value perceptions of online shoppers across different product types and price consciousness levels of online shoppers. The results of the study indicate that the price information provided by an online price comparison site influences online shoppers' perceptions of internal reference prices. However, the influence of a price comparison site on value perception differs according to product type. As evidenced by the significant interaction effect between product type and price comparison site information, the presence of price comparison sites increases both transaction and acquisition value perceptions for the non-look-and-feel product category (e.g., notebook computers), but not for the look-and-feel product category (e.g., jeans). Contrary to the expectation, online shoppers' price consciousness influences their price and value perceptions independently of price comparison site information.  相似文献

Most of the existing Markov regime switching GARCH‐hedging models assume a common switching dynamic for spot and futures returns. In this study, we release this assumption and suggest a multichain Markov regime switching GARCH (MCSG) model for estimating state‐dependent time‐varying minimum variance hedge ratios. Empirical results from commodity futures hedging show that MCSG creates hedging gains, compared with single‐state‐variable regime‐switching GARCH models. Moreover, we find an average of 24% cross‐regime probability, indicating the importance of modeling cross‐regime dynamic in developing optimal futures hedging strategies. © 2012 Wiley Periodicals, Inc.

Based upon an empirical investigation, the study draws upon the responses of 1623 tourists in Kinmen to explore the notion of destination competitiveness and how it is related to customer satisfaction with tourists’ perceptions, service performance and destination competitiveness. It also considers the question of destination competitiveness and sustainable tourism development. Variables such as tourists’ pre-visit perceptions, post-visit satisfaction toward destination attractions and resources, willingness to recommend and revisit, and competitiveness with foreign destinations are tested. The results of the study suggest that there is no correlation between tourists’ overall satisfaction and destination competitiveness. Implications of the study outcome illustrate that a destination's unique tourism characteristics can be the most important variables for destination competitiveness. In Kinmen's case, battlefields, historic relics, beautiful scenery and travel security gave it a competitive edge, despite high prices. In addition, developing the destination's brand image was found to be critical for tourism marketers and authorities in the context of increasingly global tourism competition.  相似文献

This study examines a behavioral model using latent variables of place attachment, recreation involvement, conservation commitment and environmentally responsible behavior among tourists visiting wetlands. In total, 928 usable questionnaires were collected. Confirmatory factor analysis and structural equation modeling were applied to the data by using LISREL 8.70 for Windows. Analytical results, which further elucidate the behavioral models of nature-based tourism, suggest that place attachment, recreation involvement and conservation commitment critically impact environmentally responsible behavior. In this behavioral model, conservation commitment simultaneously and partially mediates the relationships between place attachment and environmentally responsible behavior and between recreation involvement and environmentally responsible behavior. A series of management implications are drawn, including the need to use this information via a visitor interpretation strategy, greater use of partnerships with local communities and businesses to spread the importance of wetlands and of environmentally friendly behavior, and the need to work with other wetlands to share the type of visitor motivations best suited to encourage environmentally friendly behavior.  相似文献

Blogs are an Internet application that continues to grow in popularity. Many blogs contain travel-related postings and, thus, are of importance for researchers and practitioners in the tourism field. Differences in blog use have been found across different cultures. This study seeks to test whether social identity theory can explain some of the differences in extent and type of blog use. A sample of 120 travel blogs written by Korean and U.S. bloggers about three different destinations (Paris, Hawaii, and Tokyo) was analyzed. The results show significant differences that fit the assumptions derived from social identity theory.  相似文献

Foreign direct investment (FDI) inflows into Africa have increased since the turn of the millennium, mainly due to FDI growth into African countries by multinational enterprises (MNEs) from developing economies. While African governments view this growth as a positive development for the continent, many governments in the West have raised concerns regarding the institutional impact of investments from developing economies. This paper examines the impact of FDI flows on institutional quality in African countries by distinguishing investments from developed versus developing economies. Previous empirical studies have found a significant relationship between FDI flows and institutional quality in African countries but regard the relationship as MNEs rewarding African countries for adopting institutional reforms. However, little attention has been paid to the reverse causality, i.e. that FDI can cause an institutional change in African countries. Using bilateral greenfield FDI flows between 56 countries during 2003?2015, we find no significant FDI effect from developed and developing economies on institutional quality in host countries. However, aggregate FDI flows from developed and developing economies have a significant positive effect on host country institutional quality but differ concerning the impact's timing. In contrast, we find no significant effect of FDI flows from China on host country institutional quality. Our results are robust to alternative measures of institutional quality.  相似文献

This study adopts the viewpoint of the Unified Theory of Acceptance and Use of Technology (UTAUT) model to examine the change agents' behavioral intentions in the implementation of an activity based costing/management (ABC/M) system. ABC/M is an important management system that emphasizes the allocation of overhead costs on the basis of cost drivers, in order to provide relevant information for improved decision-making. A change agent is a person chosen to cause organizational change. Senior managers and often chief executives usually play the role that implements change. The behavioral intentions have been identified as a proactive attitude and action for promoting the ABC/M system in this study. Since there is little evidence of ABC/M adoption outside the United States and European countries, this research used Taiwanese companies as the sample. Questionnaires were used to investigate the factors influencing change agents' behavioral intentions to promote ABC/M systems and the type of facilitating conditions that affected the extent of usage of ABC/M systems. The questionnaires were carried out through the perspective of user acceptance of information technology (IT). Furthermore, the aim of this paper is also to explore whether use of the ABC/M system will produce an improved effect on performance. The empirical results from 100 valid responses collected indicate that performance expectancy and social influence directly affect change agents' behavioral intentions. Both change agents' behavioral intentions and facilitation conditions are important constructs that affect the extent of usage of ABC/M systems. The extent of ABC/M usage is also significantly associated with relative financial and non-financial performance. The results demonstrate that the adaptive UTAUT model is applicable for measuring change agents' behavioral intentions in current implementations of ABC/M systems. The study also reveals the positive effect of change agents on the performance of ABC/M systems.  相似文献
