The objective in this research is to propose an index for customer relationship management instead of utilizing RFM or share of wallet. This study examined whether the number of days from contract to initial usage can be used as the index for customer management. For this purpose, an empirical analysis was conducted by using a Bayesian model with purchase history data of a single year and three years regarding two kinds of credit cards and a customer master data. The results of the empirical analysis showed the shorter duration to the contract day, the amount of money for the one hundred eighty days from initial usage became higher. These results clarified that
the days can be utilized as the index for customer management. In the conventional customer management index such as RFM, it is necessary to store purchase history data for several months in a data warehouse, however, this proposed method does not need to store transaction data since the duration data can be utilized. Hence, this index can promptly find problematic customers.

In this paper, we studied the shelf-space allocation problem (SSAP). It is quite common recently to implement product design during a selling season and drastically change assortment decisions based on shelf-space allocation in response to up-to-date demand observations. While there are many literatures related to SSAP, However, existing literature assume that the demand is stationary. In this paper, we propose a dynamical framework to make shelf-space display decisions, in which space elasticity and potential demand are sequentially estimated using the latest data containing display space and sales for each product.

Abstract. Most brand managers need an effective and convenient method to measure the image of their brand that is held by consumers. One approach is to use reaction time as an indicator of the strength of the connection between brand and brand associations. In this study, an Internet survey is used to collect both responses and response (reaction) times for a series of questionnaire items. An appropriate survey mechanism is developed and two hierarchical Bayesian models are examined to determine which is more suited to measuring brand image. The simpler model measures only the weight of the brand association as indicated by consumer responses to the questionnaire items; more complex model measures not only the weight of the brand association but also the consumer’s ability to recall the brand. The results indicate that the simpler model is quite suitable for practical use.

Most brand managers are interested in measuring the degree of purchase intention of their brands. Purchase intention is useful to predict the future earnings of a brand. However, previous research has not measured brand purchase intention to learn the state of the brand. Therefore, this research proposes a method to measure the degree of brand purchase intention by using respondents’ reaction time between reading and answering a query about a brand. An original survey method to collect reaction time was developed and the results of this survey were analyzed by GLMM. The random parameters were estimated by the MCMC method. Because the respondents’ reactions are influenced by their past purchase experiences, the model in this research is developed for not only reaction time but also past purchase experience as an explanatory variable. Thus, the proposed model enables the measurement of purchase intention except for the influence of past purchase experience. The estimated parameter results clearly show the difference among brands and the present state of each brand.

The purpose of this research is to offer the point which utilizes the brand association network for brand management. For this purpose, the consumer survey was performed four times from the same respondents in order to collect brand association networks.
The following three points became clear from result of this survey
● The brand association network change with time
● The change is not only an addition and disappearance of the association in a network, but also combination of a link, and cutting.
● The relations among associations are not stable, and changes with time. This means that a certain association meaning has also changes with time.

In order to manage a brand, it is necessary to collect the brand association and to confirm what brand image a consumer has. Various methods to collect brand association have been proposed through previous studies. Previous methods have advantages and disadvantages, and they were selectively used by a brand manager according to his/her purpose to manage his/her brand. Since those methods have not been classified systematically, this study discussed the usage of past proposed methods with regard to their feature and tried to classify these past methods.

Four research methods (free association, sentence completion tests, cartoon completion tests, respondent association network) were compared in order to clarify the characteristics of methods to collect brand association. The result of an experimental study indicates the characteristics of each method. In this study past studies relating to collecting brand association were reviewed and an experimental study was conducted. The result of the experimental study indicates the relationship between the purpose and method of collect brand association and touches on practical use in business. At the end of the study, future challenges and the pros and cons of each of the methods covered are discussed.

With the diffusion of MROC (Marketing Research Online Community), the result of this study revealed that it is possible to obtain valuable information from dialogue of respondents in a website community. MROC gives marketing staff good news in order to carry out the marketing activeties. However, MROC creates a new problems that is the difficulty to summarize the dialogues in the website community. In order to overcome this problem, this study proposed a method to unify respondents’ attribute, their dialogues and their needs which underlie their dialogues.

People have two kinds of memory system. One is long-term memory and the other is short-term memory. Long-term memory keeps knowledge and experience and short-term memory keeps what he/she felt in the moment. The knowledge and experience which are kept in long-term memory are collected in conventional marketing research, however, the contents which are kept in short-term memory have not been collected before. It is also necessary to collect the contents in short-term memory in order to understand an actual consumer’s experience and opinion correctly. Thus, through this perspective, this study was conducted in order to confirm the possibility to collect what a consumer sees or feels by using mini-blog, Twitter. A result of empirical research showed that proposed method in this study is effective to collect short-time memory, since it is possible to collect the contents and impressions of the ads which a respondent has seen on his/her way to work.

In this paper, we analyzed the influence of the Global Financial Crisis on the grocery-purchasing behavior of consumers in Japan. We used the daily scanner data of a supermarket chain in Hokkaido, aggregated over the top ten branches in terms of the number of customers between January 2008 and December 2009. We built systems of itemlevel demand functions for four categories: raw eggs, milk (excluding low-fat milk), natto (fermented soybeans), and
tofu. Each system was estimated for the pre- and post-crisis periods. The overall results show that, in most of the categories,the consumers became more sensitive to prices after the crisis. With regard to item-level price elasticity, we found three types of changes in the estimates of own- and cross-price elasticities, which were increased own elasticity only, both increased own and cross elasticity, and increased cross elasticity only.

The understanding of consumer product and brand image is vital to the implementation of marketing. The understanding of consumer image through associative networks in particular allows for a deep understanding of the relationships between associations and provides effective business hints. In this study a new research method for understanding consumer images through associative networks was proposed and an empirical study was held to determine the effectiveness of this proposed method. Analyzing the survey results showed that the associations obtained by having participants create associative networks are sufficient for use in marketing purposes, as intended.
