Gray market activities have become global, occurring not only in less developed or volatile markets, but also in many well-developed markets. Although the gray market problem has been discussed in the literature, pertinent research from a demand perspective remains scarce. This study establishes a valid measure of consumer attitude toward gray market goods and investigates the relationships between consumer attitude toward gray market goods and their antecedents. Data analysis reveals that both price-quality inference and risk averseness significantly and negatively affect consumer attitude toward gray market goods. Strategies for managers of international brands to address gray market problems are presented.

Green consumption involves comprehensive concerns that address the broad scope of sustainability, ecosystem balance, profit‐generation and people. Identifying the factors that influence consumers' purchase behavior enables manufacturers to understand consumers' decision‐making processes and can help them develop more environmentally beneficial products. However, scholars have recently found that a gap exists between environmental concern and consumers' actual purchase behavior. The purpose of this paper is to use cognitive behavior theory to investigate the drivers of green consumption behavior and the missing link in the concern–behavior gap. After collecting 375 valid questionnaires, this study validated the proposed conceptual model using structural equation modeling. The revised model indicates that environmental involvement, informational utility, green advertising skepticism and green trust are antecedent variables of consumer attitudes toward green products. Additionally, this study also provides a possible explanation of and remedies for the concern–behavior gap. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment

Purpose -Innovation has attracted considerable interest in recent years in improving competitive advantage for both profit and nonprofit organizations. Service innovation offers the potential for substantially improving the performance, but performance gains are often obstructed by users' unwillingness to accept and use available systems. This research aims to use the concept of Reasoned Action Theory to further examine consumer attitudes toward service innovation and its antecedents. Design/methodology/approach -By focus group discussion and literature review, a conceptual model with six postulated hypotheses is proposed. The Electronic Toll Collecting (ETC) system launched by the Taiwanese government is selected as the service innovation to test the model. A structured questionnaire is designed to collect field data. The structural equation model with LISREL VIII program is used to estimate the structural coefficients and to test the hypotheses. Findings -The results show that perceived ease of use, perceived price fairness, risk averseness and satisfaction with existing service significantly influence consumer attitude, and then influence consumer's intention to adopt service innovation. Practical implications -Before introducing a service innovation, the service provider must seriously consider the possible difficulties of usage and risk from the consumer's perspective. Originality/value -Compared with product innovation, research focusing on service innovation is relatively scarce. Services have specific characteristics of intangibility, inseparability, heterogeneity and perishability. Hence, the factors influencing the consumer adoption of service innovation may be different from those of product innovation.
