Purpose - Present study aimed at investigating the factors that may affect consumers' decision confidence and decision comfort inducing choice commitment taken place at the stage of post-decision/pre-outcome. This study explored whether there are positive effects of dominance and instrumentality of chosen product on the decision confidence, and also identified whether there are positive effects of choice easiness and goal achievement-related affect felt at the chosen product on the decision comfort. Research design, data, and methodology - Portable digital camera as experimental product was used. 260 data were collected from college students. Four were removed from the analyses because they did not complete the questionnaire. Eighteen were removed because they indicated not experiencing the camera in the past. 238 data were used at the analyses to verify hypotheses by structural equation model in AMOS 21.0. Results - First, both of the consumers' decision confidence and decision comfort positively affected choice commitment. Second, the dominance as well as the instrumentality had positive impact upon the decision confidence. Third, the choice easiness and goal achievement-related affect felt at the chosen product had positive impact on the decision comfort. In sum, present study identified the mediation roles of the decision confidence in the effects of both dominance and instrumentality of the chosen product on forming choice commitment, and also found the mediation roles of the decision comfort in the effects of choice easiness and goal achievement-related affect felt at the product on forming choice commitment. Conclusions - Focusing on the stage of post-decision/pre-outcome in decision making process, present study contributes to advancing the choice commitment theories by exploring the positive effects of both dominance and instrumentality of chosen product on the decision confidence, and by finding the positive effects of both choice easiness and goal achievement-related affect felt at the chosen product on the decision comfort. Marketers should promote their products' dominance and instrumentality by showing the superior roles of their product attributes in achieving consumption goal, and should help consumers feel comfort by making choice process easier and giving information that could help feel the goal achievement-related affect at their product chosen.

As the role of retail stores in distribution channels becomes more significant and competition among them becomes more fierce, retail stores are making efforts to gain a dominant position in market share. And as such, consumer store choice behaviour is becoming more diverse and complex. The purpose of this study was to analysis the store choice process and to aid in understanding the types of store choice behaviors. 30 subjects were sampled by focus sampling and investigated by in-depth interview. Some consumers went through all stages of store choice process and others skipped some. The consumers who usually had no plan to visit stores and who purchase without problem recognition process were categorized as opportunity-taking type, and the consumers who visited just one store without external search of other store information were categorized as store-loyal type. Finally, the consumers who searched store information externally were divided into brand-oriented type and value-seeking type. The brand-oriented type represented the consumers who did not evaluate stores in detail because which store to visit was decided on brand; and the value-seeking type represented the consumers who did in fact evaluate stores in more detail according to the items and trends in fashion. This study is meaningful in that it provides a dynamic store choice process and examines related variables thereto.

This paper analyzes Korean residential tenure choice for house which is the most important in Korean households' assets. Data used in the analysis is the data of Korean Labor and Income Panel Study for the period from 1998 to 2006 and with 2341 households. In this paper, a household chooses a housing tenure mode, either by renting or by owing house. We use a mixed-logit panel model as an estimation model to take into consideration household's heteroscedasticity of preference in tenure choice. It turns out that the heteroscedasticity is significant in households' tenure choice behavior, implying that Korean housing policy emphasizing supply side should consider the demand side.

Economists have identified informed consumer choice as one element of a better-functioning health care market, and thus increased attention is directed to the role of information in the health care system. In this country, however, little work has been done for understanding consumers' search behavior in health care market. Based upon this observation, expectant mothers' information search for the choice of delivery care institution was investigated. In doing so, two hypotheses were proposed: 1) Those women who were more active in the search for information would make choice of a delivery care institution with more confidence and would feel greater subsequent satisfaction. 2) The activeness of expectant mothers in information search would depend upon their various personal characteristics, such as socio-economic status, obstetric conditions, and knowledge and attitudes in relation to delivery and health care. The data used for the analysis were collected through face-to-face interviews with those women who had childbirth during the period from January 1, 1996 to the date of interview in February 1998. The survey was conducted using prepared structured questionnaire in Seoul. The sample was drawn from each of arbitrarily defined four regions of Seoul, Northeast, Northwest, Southeast and Southwest, in proportion to the number of births reported in 1996 in each of them. The distribution of the interviewed women by educational level was made similar to that of mothers of new babies reported in 1996. The sample size was planned to be about 300, but ended up with 319. The results of analysis were generally consistent with the proposed hypotheses. Apparently, information increased expectant mothers' confidence in selecting a delivery care institution and subsequent satisfaction with the institution. Indication is that policy efforts should be strengthened to produce and disseminate relevant, comprehensible and credible information that can aid patient decision making. Also, attention should be directed to motivate patients to actively engage in information search from adequate sources.
