The object of this study is to examine the informational effect of the rating change announcement on the capital market. For this study, daily stock prices from January 1993 to February 2001 and daily bond prices from July 2000 to February 2001, for the bond market are used. In the stock market, we could not observe any statistically significant stock price reaction to rate change announcements from July 2000 to February 2001. However, if rating agencies announce more than two degradation for the period of January 1993 to February 2001, statistically negative significant stock price reactions are observed. On the other hand, there is no statistically significant stock price reaction to any other rating change announcement. In the bond market, there is no statistically test on the bond price reaction, but the general directions of bond price movements are consistent with the effect we can expect from rating change announcements. Generally, when the rating agencies degraded more than two grades at once, a cumulative abnormal returns move negatively during the overall period. In this case, we can say that rating agencies' role is to confirm information or investor's expectations. However, for the other cases, we could not observe my significant movement before or on the event data.

It empirically studied the effects of customer status, truth of messages, and involvement on loyalty when customer experience demotion in loyalty program. A scenario based 2(customer demotion: highest status customer/middle status customer) ${\times}$ 2(truth of messages: high/low) ${\times}$ 2(involvement: high/low) between-subjects factorial design experiments are conducted for the hypotheses. According to the result of ANCOVA, highest status customer's loyalty and middle status customer's loyalty decrease when they experience demotion. But middle status customer's loyalty less decreases than the highest status customer. Loyalty of the group who feel high truth of message less decreases than those of other groups. And loyalty of the low-involvement group's loyalty less decreases than those of other groups. Moreover it test three way interactions among customer status, truth of messages, and involvement. The result indicates that loyalty of the group who feel high truth of message and low-involvement less decreases than those of other groups.

This study aimed to analyze the effect of the change in CP class of a firm on the abnormal yield of its stock price. As a result, it was found that the change in CP class of a firm had an effect on the abnormal yield. That is. the abnormal yield rose when the class of CP rose while it dropped when the class of CP dropped. And it was analyzed that the class of CP in the firm in which its current net gain was great while it dropped in the firm in which the current net gain was small. And it was found that the CP class of the firm with the high debt to equity ratio rose when the CP class of the firm changed, whereas it rose in the firm with the low debt to equity ratio. But it was found that the size of majority shareholders equity rate in a firm, the size of corporate value of the firm, the size of cash flow of the firm and the size of the burden of financial costs of the firm were not related to the abnormal yield of its stock price. This study has its significance in analyzing the effect of the information on the change in CP class of the firm on the capital market. But it has its limitations in the sample firm and the selection of the point in time of disclosure.

본 연구는 급경사지 정비 사업 이후 현장을 재평가하고, 등급을 산정할 때 보강시설로 인한 등급 하락의 효과성을 검증하기 위해 역량 지표를 추가하여 12명의 전문가와 15개 지점에 대한 현장평가를 실시하였다. 15개 지점 중 11개소에서 점수가 변화되었으며, 6개의 지점에서 등급이 하락하였다. 등급의 변화가 크지 않아 개선해야 할 점이 있지만 본 연구는 향후 급경사지 등급 조정 연구에 활용될 수 있을 것으로 판단된다

This article estimates the economic values of changes in water quality of the Paldang Watershed by using the Choice Experiment (CE). The conditional logit model estimation results show that a small improvement in water quality from the 'status quo' level to the level of 'very good' increases average household's monthly utility by 3,157 Won, whereas a water quality degradation down to the 'normal' level gives rise to an increase in the monthly average utility by 9,649 Won. The corresponding social gain and loss of water quality changes to the Metropolitan Area were thus estimated about 285 billion Won and 872 billion Won, respectively. This article seems meaningful in that it resorts to the new water ecosystem classification criteria and indices that are respondent-friendly. They help a CE study like this to overcome one of its critical weakness that the number and contents of attributes of a CE study can quickly add to the information overload problem, especially where the environmental good under investigation is hard for ordinary respondents to understand.

하절기에는 이등유에 의한 납유정지. 서균수 및 체세포수의 증가에 따른 위생등급 하락. 0.2% 정도의 유지율 저하 및 10% 이상의 산유랑 감소에 의하여 일년 중 유대 수입이 가장 적은 계절이다. 이러한 유질저하 및 산유량 감소에 따른 경제적 손실은 목장 규모 및 사양관리수준에 의해서 수십만원에서부터 수백만원에 이르기까지 매우 다양하다. 그래서 낙농가에 있어서는 가장 힘든 계절이다.
