Knowledge can influence the whole decision-making process of consumers. While green product knowledge is often conceptualized as a direct antecedent of green purchase intention, empirical findings in support of this relationship are inconsistent. Based on 236 samples, this study investigates how green product knowledge promotes consumers’ green purchase intention. Results show that green trust and perceived consumer effectiveness partly mediate the relationship between green product knowledge and green purchase intention. The relationship between green trust and green purchase intention is positively moderated by perceived price. Compared with low perceived price, green trust has a greater effect on green purchase intention in the case of high perceived price. However, the relationship between perceived consumer effectiveness and green purchase intention is not moderated by perceived price. This study provides a new insight into green product knowledge and how to promote green purchase intention, and the findings help government and enterprises to formulate strategies to promote consumers’ green purchase intention.

PurposeThe purpose of this research is to help better understand the impact of online user reviews on sales of search goods.Design/methodology/approachThis research is based on digital camera sales data collected from amazon.com and two studies are included in this research. The first study is based on a static model and sample data from one time stamp. The second study is based on two sample data collected from two different time stamps, and a dynamic model is proposed.FindingsThe results from the first study reveal that the average online customer review, the number of online reviews, the price and the camera's physical properties such as the number of pixels and the optimal zoom number (but not LCD screen size) have significant influence on digital camera sales. The results from the second study show that the sales from the previous period are an important indicator for future sales. In addition, change in price, change in average online review rating and change in the total number of online reviews are all significantly associated with future sales.Research limitations/implicationsThe research reveals that there is a significant relationship between the online user review and sales of search goods, and the influence of online user reviews on search goods sales is different from that on experience goods. It also recognizes that the product specifications influence the sales of search goods. In addition, the research on search goods shows that price at the specific time and price changes are significant factors affecting sales.Practical implicationsThe research indicates that retailers should provide channels for, and encourage, customer online reviews for search goods to improve sales. It is also beneficial for online retailers to provide detailed product attributes to help their customers make the purchase decision. Carefully designed and executed price promotions could also be effective ways to improve sales of searchable goods.Originality/valueThis study is one of the first attempts to investigate the impact of online user reviews on sales of search goods.

PurposeThe COVID-19 outbreak has been rapidly spreading around the world for more than a year. However, few studies have explored the connection between the perceived severity of COVID-19 and purchase intention of the health-related products, for example, organic food. Based on the stimulus–organism–response (S-O-R) framework, this study examines the influencing mechanism of perceived severity of COVID-19 on purchase intention of organic food.Design/methodology/approachTo evaluate the proposed model, an online survey was utilized to collect 1,104 valid questionnaires from China.FindingsThe findings suggest that (1) the perceived severity of COVID-19 has a significant positive impact on purchasing intention; (2) health consciousness acts as a mediating role between perceived severity of COVID-19 and purchasing intention and (3) perceived inconvenience negatively moderates the connection between perceived severity and purchase intention.Originality/valueThe findings of this paper provide new insights into the positive effects of COVID-19 and pave the way for governments and enterprises to promote the purchase behaviour of organic food.

Purpose This paper aims to demonstrate both the positive and negative effects of loyalty programs. The study proposes a model to demonstrate why and how loyalty program strategies can result in good customer relationships and customer entitlement behaviors. Various configurations of three different loyalty program strategies are analyzed – tangible rewards, preferential treatment and perceived status. Design/methodology/approach The authors’ hypotheses were tested by analyzing the survey data of 152 frequent flyer program members in China through partial least squares-structural equation modeling. Fuzzy-set qualitative comparative analysis (fsQCA) was used to test different configurations of the three loyalty program strategies. Findings A net effects analysis demonstrates that loyalty programs are a double-edged sword. While loyalty programs can improve customer relationships, strategies based on perceived status have a positive relationship to customer entitlement, which may lead customers to expect extraordinary efforts from companies, such as greater discounts and extra privileges. Using fsQCA, the authors determined four sufficient configurations of high level of relationship quality and high level of customer entitlement, which also support their findings. Originality/value First, this study expands the research on loyalty programs by providing an examination of their positive and negative consequences. Second, by proposing the configuration paths that lead to high level of relationship quality and high level of customer entitlement using fsQCA, this research enriches research on the net effects of loyalty programs, providing researchers and practitioners with a more comprehensive understanding of loyalty programs. Third, this research extends the concept of customer entitlement to the context of buyer–seller relationships by introducing perceived status as an important antecedent of customer entitlement and by identifying four sufficient configurations.

PurposeReducing food waste is one of the critical challenges of campus canteens. This study aims to test an extended theory of planned behaviour that incorporates moral norm, food taste and campus food-saving climate to understand the influence factors of food waste behaviour on campuses.Design/methodology/approachTo evaluate the proposed model, an online survey was utilized to collect 513 valid questionnaires.FindingsThe findings suggest that (1) attitudes towards food waste, subjective norm and perceived behavioural control have a significant influence on intention to reduce food waste; (2) Moral norm and food taste are shown to have a favourable effect on the intention to reduce food waste; (3) Food waste behaviour is significantly determined by intention to reduce food waste; (4) Campus food-saving climate negatively moderates the relationship between intention to reduce food waste and food waste behaviour.Originality/valueThis study paves the way to enhance the understanding of the factors of food waste among college students. In addition, this study develops practical strategies to prevent large amounts of food from being wasted on campus.
