Purpose: To find out the appropriate probability distribution of credit card usage behavior by considering the relationship among income, expenditure and credit card usage amount. Such relationship is enabled by Korea's especially high penetration of credit card. Method: Goodness-of-fit test and effect size statistic W were used to identify the distribution of income and credit card usage amount. A simulation model is introduced to generate the credit card transactions on individual user level. Result: The three data sets for testing had either passed the chi-square test or showed low W values, meaning they follow the exponential distribution. And the exponential distribution turned out to fit the data sets well. The r values were very high. Conclusion: The credit card usage behavior, denoted as the counts of users by usage amount band, follows the exponential distribution. This distribution is easy to manipulate, has a variety of applications and generates important business implications.

Purpose: It is to seek for an appropriate cost rate analysis methodology of credit card value propositions in Korea. For this issue, it is claimed that methodologies based on probability distribution is more suitable than methodologies based on data-mining. The analysis model constructed for the cost rate estimation is called VCPM model. Methods: The model includes two major variables denoted as S and P. S is monthly credit card usage amount. P stands for the proportion of usage amount at special merchants over the whole monthly usage amount. The distributions assumed for P are positively skewed distributions such as exponential, gamma and lognormal. The major inputs to the model are also derived from S and P, which are E(S) and the aggregate proportion of usage amount at special merchants over the total monthly usage amount. Results: When the credit card's value proposition is general discount, the VCPM model fits well and generates reasonable cost rate(denoted as R). However, it seems that the model does not work well for other types of credit cards. Conclusion: The VCPM model is reliable for calculating cost rate for credit cards with positively skewed distribution of P, which are general discount card. However, another model should be built for cards with other types of distributions of P.

The research aims to help merchant acquiring institutions gain a better insight on what merchant establishments in the Singapore market perceive of the costs they incur due to credit card acceptance. The research attempts to study the Singapore market and establish if increased credit card usage does increase costs for the merchant establishments that accept credit cards, this will help to acquire institutions in Singapore have a better understanding of merchant perceptions and what drives or deters credit card acceptance in the Singapore market. The survey was based on an interview of merchant establishments and the views of the merchants and was not based on their financial data. As a first step, the variables used in the survey were tested for interdependence using Chi-square tests; subsequently data reduction using factor analysis was performed and finally linear regression to establish a relation between dependent and independent variables. Merchant establishment believe accepting credit cards and increasing volume is costlier compared to another form of payment, but have mixed awareness about interchange fee. It also indicated that interchange fee and cardholder benefits are independent of the merchant establishments. The study only broadly attempts to gauge merchants view if increased credit card usage has increased costs for them.

Frequencies, Cronbach's Alpha, factor analyses, t-test, Pearson's correlation analysis, and regression analyses were conducted by SPSS WINDOWS. The results from this study were as follows. First, there were significant differences between credit card usage group and non-usage group in the means for future preparation, stingy attitude, and planned expenditure. However, there was no significant difference in the mean of money management behaviors. Second, for the credit card usage group, the significant variables affecting money management behaviors included sex, grade, experience of consumer education, father's occupation, monthly household income, future preparation, stingy attitude, methods of emotional change, planned expenditure, and negative recognition. On the other hand, for the non-usage group, grade, experience of consumer education, father's occupation, way of success, future preparation, stingy attitude, planned expenditure, and conditional permission were significant. These results imply that financial management education including values about money and consumption patterns should be conducted.

This classification is based on the study of factors taken into consideration during shopping and disparities in credit cared usage., The specific goals of this study are the following : First it is to classify female consumers over age 20 into "shopping orientation" types and "clothing purchase behavior" types according to their perception towards department store credit care usage. Second it is to discover the degree of perceived utility of department store credit card in clothing purchases. Third finally it is to assist a department store credit card market researcher establish a marketing strategy to best address consumers; needs and wants in credit card purchases The study methodology utilized and the results found were that : 1. The division of consumers into positive and negative groups based on factor analysis with the positive group found to have favorable attitudes towards department store credit card usage. 2. Classification of female consumers into three " shopping orientations" : fashion purchasing economic value purchasing and convenience purchasing. The positive group were predominantly fashion convenience purchasers who valued low cost and convenience over "fashionability" 3. The three classes of "purchase behavior" used were impulse buying planned buying and unplanned buying. The positive group those who had favorable attitudes toward department store credit cards. made mostly impulse and unplanned purchases while the negative group made largely planned purchasee the negative group made largely planned purchase.

The purpose of the study was to examine female college students' credit card usage characteristics and to investigate differences in buying propensity of clothing including impulse buying, consciousness, and conspicuous consumption among their buyer groups according to credit card use and personal characteristics. The questionnaires were administered to female college students in Seoul. The total of 588 questionnaires were collected and statistically analyzed by descriptive statistics, factor analysis, Analysis of Variance (ANOVA), and Duncan's test. Female college students' arrear as well as credit card use have been increasing, and they tend to purchase low price clothing item using credit card. Buying propensity was classified into three factors. There were differences in buying propensity of clothing including impulse buying, fashion consciousness, and conspicuous consumption among buyer groups according to the credit card use and personal characteristics. Students who have credit card and arrear experience, are heavy credit user, and purchase more clothing showed high impulse buying propensity. Students who purchase more clothing monthly with credit card were more fashion-conscious. Students who have credit card, are heavy credit user, and purchase more clothing showed high conspicuous consumption propensity. Implications and future research directions were discussed.

According to the clear potential of mobile banking growth, many studies related to this are being conducted, but in Korea, it is concentrated on the analysis of technical factors or consumers' intentions, behaviors, and satisfaction. In addition, even though it has a strong customer base of 20s, there are few studies that have been conducted specifically for this customer group. In order for mobile banking to take a leap forward, a strategy to secure various perspectives is needed not only through research on itself but also through research on external factors affecting mobile banking. Therefore, this study analyzes impulsiveness, credit card use, and SNS addiction among various external factors that can significantly affect mobile banking in their 20s. This study examines whether the relationship between impulsiveness and mobile banking usage depends on whether or not a credit card is used, and checks whether a customer's impulsiveness is possible by examining whether a credit card is used. Based on this, it is possible to establish new standards for classification of marketing target groups of mobile banking. After finding out the static or unsuitable relationship between whether to use a credit card and impulsiveness, we want to indirectly predict the customer's impulsiveness through whether to use a credit card or not to use a credit card. It also verifies the mediating effect of SNS addiction in the relationship between impulsiveness and mobile banking usage. For this analysis, the collected data were conducted according to research problems using the SPSS Statistics 25 program. The findings are as follows. First, positive urgency has been shown to have a significant static effect on mobile banking usage. Second, whether to use credit cards has shown moderating effects in the relationship between fraudulent urgency and mobile banking usage. Third, it has been shown that all subfactors of impulsiveness have significant static relationships with subfactors of SNS addiction. Fourth, it has been confirmed that the relationship between positive urgency, SNS addiction, and mobile banking usage has total effect and direct effect. The first result means that mobile banking usage may be high if positive urgency is measured relatively high, even if the multi-dimensional impulsiveness scale is low. The second result indicates that mobile banking usage rates were not affected by the independent variable, negative urgency, but were found to have a significant static relationship with negative urgency when using credit cards. The third result means that SNS is likely to become addictive if lack of premeditation or lack of perseverance is high because it provides instant enjoyment and satisfaction as a mobile-based service. This also means that SNS can be used as an avoidance space for those with negative urgency, and as an emotional expression space for those with high positive urgency.
