In these days, an individual is evaluated by his or her credit. So, it is very critical for an individual to know his or her credit rating and then to try to improve the credit rating. But, there are few services to analyze credit status for an individual and inform the person of the credit. In fact, it could be impossible to let a person know how to improve his or her credit rating. Against this backdrop, we research on a credit management model to analyze credit status of an individual rapidly and propose individual-customized method to improve the credit rating. We set up the model and design it in detail. This servie would certainly make it convenient for an individual to retrieve credit rating and improve it.

On the basis of intertemporal utility maximization theory and stock-adjustment hypothesis, a multivariate stock-adjustment credit demand model, which included on- and cross-adjustment effects of credit and cross-adjustment effects of assets was developed. With weighted four-year panel data from 1983 and 1986 Surveys of Consumer Finances, the theoretical model was tested using two-stage estimation method for tobit model. The results supported the hypothesis that, in general, the household demand for a certain type of credit was related to the demand for other types of credit and asset components in the portfolio. The household demand for mortgage credit, installment credit and revolving credit card debt depended not only on the disequilibrium of itself but on the disequilibrium of the other types of credit and asset components in the portfolio. The household demand for non-installment credit was related not to the disequilibrium of itself and other types of credit but to the disequilibria of asset components in the portfolio.

The increasing late-payment rate of credit card customers caused by a recent economic downturn are incurring not only reduced profit of department stores but also significant loss. Under this pressure, the objective of credit forecasting is extended from presumption of good or bad customers to contribution to revenue growth. As a method of managing defaults of department store credit card, this study classifies credit delinquents into some clusters, analyzes repaying patterns of customers in each cluster, and develops credit forecasting system to manage delinquents of department store credit card using data of Korean D department store's delinquents. The model presented by this study uses Kohonen network, a kind of artificial neural network of data mining techniques to cluster credit delinquents into groups. Logistic regression model is also used to predict repayment rate of customers of each cluster per period. The accuracy of presented system for the whole clusters is 92.3%.

본 논문은 국내 은행금응기관의 신용위험관리를 보다 효율적이고 과학적으로 지원하기 위한 통합 위험관리시스템의 프레임웍을 제시한다. 즉, 담보 보증중심의 사전관리 위주의 대출관리에서 신용중심의 사후관리 위주의 대출관리로 전환되어야 함에 따라 신용평가시스템, 대출의사결정시스템, 사후관리시스템, 그리고 통합 신용위험관리시스템에 이르기까지 각 단위 시스템이 전체적으로 하나의 시스템으로 통합되어야 한다. 특히, 통합 위험관리시스템은 신용위험을 은행전체의 신용 포트폴리오의 관점에서 측정하고 분석함을 의미한다. 통합 위험관리시스템은 개별 대출기업 혹은 개별 대출에 대한 신용위험을 분석함과 동시에 이를 기초 데이터로하여 은행 전체 신용 포트폴리오의 신용위험 노출정도를 파악한다. 또한, 개별 대출기업의 신용등급 변화로 인한 은행전체 신용위험의 변화를 자동적으로 파악하고 조기 경보함으로써 은행의 총체적인 통합 신용위험관리가 가능하도록 한다.

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.

현재 개인신용정보이용 신용카드범죄는 그 특성상 고도의 전문화와 광역화로 인해 피해 발생후 원상회복이 어렵고 범죄인의 신속한 검거와 처벌 또한 쉽지 않다. 소수의 범죄인들에 의해서 발생하던 예전의 신용카드 위${\cdot}$변조 범죄들은 현재의 신용카드 관련 범죄와는 유형과 양상이 사뭇다르다. 현대신용사회에서 개인신용정보의 중요성은 굳이 강조할 필요가 없다. 따라서 개인신용정보이용 신용카드범죄가 국민 생활에 끼치는 악영향은 한 개인과 신용카드가맹점, 그리고 신용카드회사 모두에게 엄청난 경제적 손시로가 피해를 유발하는 것이다. 이 연구에서는 개인신용정보이용 신용카드범죄와 개인신용정보 부정이용범죄에 대한 효율적 대처방안들을 다음과 같이 제시하였다. 먼저, 신용카드정보 유출의 방지를 위한 대책으로서 카드사용자의 사용의식 전환, 신용카드매출전표의 인쇄내용 개선, PG(Payment Gateway) 업체 등을 통한 카드정보 암호화의 법제화를 들었다. 그리고, 비밀번호 입력에 대한 보완, 키보드 프로텍션(해킹방지) 시스템의 보급, 결제내역 즉시통보의무의 법제화를 들었다. 또한 다양한 본인 인증 방법으로서 전자인증서를 통한 인증, 생체인식 기술을 이용한 인증을 들었으며, 개인신용정보를 보호받지 못하는 나라에서의 신용카드사용을 제한하여 신용카드관련 피해 발생을 최소화하는 방안을 제시하였다. 그러므로 개인신용정보이용 신용카드범죄에 대한 효율적인 대처를 위해서는 카드사용자, 카드사, PG 업체, 정부 기관, 공인인증기관 등의 종합적인 협력과 노력이 요구되며, 경각심을 고취시키기 위한 처벌법규의 강화와 정책적 대안을 수립하여 현대사회에서의 건전한 신용문화를 형성하여야 할 것이다.
