This study proposes a new collaborative filtering model that integrates Restricted Boltzmann Machines. The proposed two-stage model is applied to household-level supermarket purchase data. Results show that our model fits the data better and outperforms existing collaborative filtering methods in predicting shopping patterns. The proposed model also improves interpretations of market complexity and common causes of coincidence associated with customers’ multi-category purchases.

One specific manifestation of CSR is the solicitation of donations in collaboration with an NGO. Especially in an online environment, companies can easily control if they present donation options to consumers either before or after the actual purchase moment of their products. The aim of this paper is to investigate how the sequence of purchase and donation requests in the customer journey influences the willingness to donate to a charitable cause and the potential revenues for the seller. As theoretical frame, we use two related concepts of moral self-regulation, namely moral licensing and moral cleansing. We assume that consumers spend a higher sum on a luxury product after donating to an NGO (moral licensing) and vice versa donate a higher sum to charity after purchasing a self-indulgent product (moral cleansing). While we do not consider luxury products as morally questionable per se, prior research has shown that consumers repeatedly feel bad after purchasing a luxury item. Our results indicate that the moral cleansing effect is present in our experiment. On average, participants who first indicate their WTP for a luxury product are subsequently more prone to donating money to an NGO. We could not observe a moral licensing effect at large. Both conditions lead to comparable mean WTP measures, hence to similar total potential revenues. In general, our results indicate that both parties profit the most, if donation options are available after purchase decisions.

In consideration of the existing eco-friendly marketing research, it is only focusing on the type and characteristics of eco- friendly consumers. Therefore, in order to carry out more systematic and comprehensive eco-friendly marketing research, it is necessary to complement the comprehensive model that examines the mechanism by which the leading variables of the enterprises factors affecting consumer’s eco-friendly consumption behaviors. In this research, based on previous studies and literature considerations, it tries to present a research model that the core benefits and relational benefits of the retail store which is the advantage of VMD affect eco-friendly consumption behavior through consumer's implicit and explicit motivation. And, considering the environment, this study assumes the regulatory role of the perceived risk on the environmental problems under the relationship between green consumption motive and consumption behavior. The purpose of this research is as follows. First, it clarifies the influence of the benefits of eco-friendly VMD in fashion retail stores on the eco-friendly consumption motive, which is a psychological factor of consumers, as a leading variable of corporate factors affecting consumers’ green consumption behavior. The core benefits and relational benefits provided by eco-friendly VMD will identify differentiated impacts on consumer motivation, which is a psychological factor that drives green consumption behavior. Second, the types of motivations that cause eco-friendly behavior are classified into explicit motivation and implicit motivation, and this study tries to find out which type of motivation better predicts eco-friendly consumption behavior. Third, it tries to verify the moderating role of environmental perceived risk in the relationship between explicit motivation, implicit motivation and green consumption behavior. By further organizing the theme of eco-friendly marketing research, this study has its academic significance in that it derives a comprehensive model, moderating consumers’ green consumption behavior regarding eco-friendly marketing stimulates. It reveals the mechanisms that affect green consumption behavior backed by fashion retail stores where consumer buying behavior actually takes place. Based on this research, it is expected that subsequent studies of a more fragmented viewpoint for fashion retail stores’ eco-friendly marketing will be developed that will give consideration to consumers' green consumption behavior. Practically, the results of this research can be utilized very conveniently. In a practical dimension, if it becomes possible to thoroughly understand the mechanism by which eco-friendly VMD stimulation leads to green consumption behavior, retailers are possible to formulate an environmental marketing strategy peculiar to the target market segment. From a socio-policy perspective, retailers can encourage consumers' eco-friendly consumption by giving a stimulus of VMD to them. Moreover this study will promote companies to develop and manage healthier and more sustainable products.

This paper makes a detailed comparison between two metrics designed for measuring customer’s satisfaction in the retail industry. The first metric, which is called the customer service level, has not been widely used due to the intrinsic requirement on the parameter assumption(s) of the demand distribution. Unlike the customer service level metric the in stock ratio metric does not require any requirements on the demand distribution. And the in stock ratio metric is also very easy to understand the meaning. To develop the detailed planning activities for business with the in stock ratio metric on hand one should collect some information as following : 1) POS (Point of sales) data, 2) Inventory Data 3) Inventory Trend.

management on corporate image and purchase intention. Research design, data, and methodology - The study employs monthly time series data from October 2013 to November 2013, analyzing variables to verify hypotheses. These concern three questions on marketing communication, five on public interest business activities, four on donation & sponsorship, two on donation & sponsorship activities, six on corporate image, four on volunteer service, and five on demographic characteristics. Results - Hypothesis 1, "Ethical management in marketing communication, public interest business, donation & sponsorship, and volunteer service positively affects corporate image," was partially adopted with significant regression of marketing communication, public interest business activity, and donation & sponsorship. Hypothesis 2, "Ethical management such as marketing communication, public interest business, donation & sponsorship, and volunteer service positively affects purchase intention," was partially adopted with significant regression of marketing communication and public interest business. Hypothesis 3, "Corporate image positively affects purchase intention," was adopted at significant regression. Conclusions - Ethical management influenced purchase intention and corporate image.
