Recently, e portion of on-line stock brokerage has been rapidly increased to be more than 50%, on the basis of contracted money. The usage of wCTS(Web Based Cyber Trading Systems) has now got into the steady state over the initial diffusion stage, which means wCTS has got more-than-half customer base in on-line service. Therefore, brokerage service providers have their competitive strategic focus on customer retention through the enhancement of customer loyalty. This study provides framework and survey results on explanation of wCTS user's loyalty, what and how factors affect wCTS user's loyalty. We adopt the results of early studies on information technology acceptance and diffusion such as TAM(Technology Acceptance Model) and IDT(Innovation Diffusion Theory). We also referred loyalty theory of marketing area and studios on CTS usage. We categorized explanation factors as three groups characteristics of users, characteristics of system, social environment. And we assumed that these three factors could affect the loyalty through two parameters : customer satisfaction and trust to the system. This study firstly shows that the ease of use and usefulness, the major factors of TAM. can also be applied to the loyalty of wCTS with resulting that the usefulness is more important than the ease of use In wCTS. Secondly, it shows that the innovative and risk-sensitive user has the lower degree of loyalty. Thirdly, it shows that the satisfaction and trust impact the loyalty simultaneously, the trust particularly impacts more strongly than the loyalty, due to the characteristics of monetary transaction in wCTS. This study provides meaningful results to the other on-line EC service fields as a first empirical research regarding the loyalty to wCTS which is a typical on-line EC service.

Because of the radical changes in the domestic and foreign economic circumstances Koreaa fisheries is confronted with difficulties. Along the end of the UR marine products of other nations are rushing into Korea. Also migration of labor to other industries and rise of wage level in Korean fisheries deteriorate managerial conditions. But in Korea which has little natural resourses fisheries is still more important. That is \circled1 creating job opportunites \circled2 increase of income \circled3 supply of foodstuffs and animal protein \circled4 acquisition of foreign currency \circled5 enlargement of domestic market for industrial products \circled6 development of other interrelated industries \circled7 rational use of domestic resourses \circled8 diversification of population and production activites \circled9 contribution to balanced growth of national economy by the developing regional economy. These roles of fisheries in national economy mentioned above are to be excuted forward. In spite of the radical change in the economic circumstances at the end of the UR fisheries if crucial in Korea as a industry. For this our fisheries is to be made to compete with foreign fisheries. Through the cheap price and high quality our fisheries must be came to compete with foreign fisheries and meet the people's needs for marine products. For this it is necessary to maintain high productivity and competitive power. Now with the exception of a portion of the deep - sea fishing, our fisheries is generally paltry, Especially inshore fishery which is the main stock in our fisheries is very paltry and so productivity and competetive power are very low. So to develop our fisheries which has s comparative disadvantage active polices that follows below are to be promoted on a large scale. \circled1 improvement of structure \circled2 augmentation of productivity in fishing ground by making fisheries resourses \circled3 enlargement of finantial and monetary assistance \circled4 effective administration of fisheries cooperative union \circled5 activation of R&D etc These polices which need to be scientific and comprehensive are very valuable. Especially without making fishieries resources we cannot expect economy of scale, promotion of productivity and development of fisheries. And we do also endeavour to gather the results of the study and investigation about fisheries domestic and foreign and do ceaselessly put these to practical use systimatically.

Purpose - Since COVID-19, the government's expansion of liquidity to stimulate the economy has resulted in an increase in private debt and an increase in asset prices of such as real estate and stocks. The recent sharp rise of the US Federal fund rate and tapering by the Fed have led to a fast rise in domestic interest rates, putting a heavy burden on the Korean economy, where the level of household debt is very high. Excessive household debt might have negative effects on the economy, such as shrinking consumption, economic recession, and deepening economic inequality. Therefore, now more than ever, it is necessary to identify the causes of the increase in household debt. Design/methodology/approach - Main methodology is regression analysis. Dependent variable is household loans from depository institutions. Independent variables are consumer price index, unemployment rate, household loan interest rate, housing sales price index, and composite stock price index. The sample periods are from 2017 to May 2022, comprising 72 months of data. The comparative analysis period before and after COVID-19 is from January 2017 to December 2019 for the pre-COVID-19 period, and from Jan 2020 to December 2022 for the post-COVID-19 period. Findings - Looking at the results of the regression analysis for the entire period, it was found that increases in the consumer price index, unemployment rate, and household loan interest rates decrease household loans, while increases in the housing sales price index increase household loans. Research implications or Originality - Household loans of depository institutions are mainly made up of high-credit and high-income borrowers with good repayment ability, so the risk of the financial system is low. As household loans are closely linked to the real estate market, the risk of household loan defaults may increase if real estate prices fall sharply.

본 연구는 1990년대 이후의 한국경제의 성장패턴을 이해하기 위한 노력의 일환이다. 이를 위해, 본 연구에서는 Blanchard and Quah(1989)가 제시한 바와 같이 장기제약식하의 구조적 벡터자기회귀추정법(Structural Vector Auto Regression: SVAR)에 의거하여 우리나라의 경제를 오늘에 이르게 한 다양한 충격들을 식별하고 각각의 상대적 기여도를 구분하고자 하였다. 보다 구체적으로는 Blanchard and Quah의 2-변수 모형과 이를 확장한 3-변수 모형, 그리고 New Keynesian류의 선형모형을 변형시킨 두 개의 모형을 분석하였다. 특히, 후자의 두 모형은 1997년 외환위기 이후 있었던 외환시장체제(고정환율제도에서 변동환율제도)와 통화정책기조(통화총량제에서 물가목표제)의 변화를 반영하도록 구성되었다는 점에서 의의를 갖는다. 이러한 각 모형으로부터의 추정 결과를 충격반응 및 예측오차분해 분석의 형식으로 정리 비교한 결과 다음과 같은 두 가지 공통점을 발견할 수 있었다. 첫째, 경제성장률의 변동은 생산성의 충격에 주로 기인하며, 이와 같은 경향은 2000년대 이후 더 강해진 것으로 보인다. 이는 2000년대 이후 우리 경제의 성장이 잠재성장률과 밀접한 관계를 갖고 있음을 시사한다. 둘째, 2000년대 이후 충격반응의 크기나 지속성이 전반적으로 줄어드는 경향이 있다. 무역의존도가 높은 우리 경제상황에 비추어 2000년대의 전 세계적인 저(低)금리, 저(低)인플레이션 및 견실한 성장세, 그리고 중국경제의 부상이 자본 및 수출 수입 수요의 안정적인 확보를 도모하여 특히 각 부문 충격이 경제에 미치는 영향을 반감시켰을 개연성이 있다. 분석에 사용된 모형과 식별에 사용된 충격의 다양한 조합에도 불구하고 위의 두 가지 패턴은 일관되게 관측되고 있음에 비추어 볼 때, 2000년 이후 우려되고 있는 우리나라의 경제성장률 저하 현상은 잠재성장률 하락에 주로 기인하는 것으로 판단된다.

준(準)재정활동(quasi-fiscal activities)이란 흔히 중앙은행과 같은 공기업이 수행하는 활동 가운데 정부정책의 성격이 강한 활동을 말한다. 준재정활동은 정부 재정활동의 규모와 수지상황을 왜곡함으로써 재정투명성을 저해하고 잠재적인 재정위험요인을 낳기도 한다. 준재정활동은 여러 가지 측면에서 정의될 수 있는데, 본고는 중앙은행의 경우 그 고유기능인 통화정책의 수행 및 은행서비스(은행간 지급결제, 국고취급 등)의 제공에 해당하지 않는 것을 중앙은행의 준재정활동이라 정의하기로 한다. 이렇게 볼 때 우리나라의 경우 특히 문제가 되는 것은 한국은행이 민간에 제공하는 저리의 총액한도대출 및 정부에 대한 이익잉여금의 이전이다. 총액한도대출 잔고는 외환위기 이후 급증하여 2002년 말 현재 7.6조원(본원통화 대비 20.0%)을 기록하였다. 또 기금출연을 포함한 대정부 이전은 1998~2002년의 5년 동안 총 9.9조원을 기록하였다. 본고는 1994년 이후의 기간을 대상으로 한국은행 준재정활동의 규모를 측정하였다. 분석결과 만일 준재정활동이 모두 명시적인 재정활동으로 수행되었다면 외환위기 이후 공공부문 통합재정수지는 실제보다 GDP의 0.5% 정도 감소하였을 것으로 추정되었다. 이는 주로 총액한도대출의 증가와 한은 잉여금의 대정부 이전에 기인한다. 앞으로도 준재정활동을 축소하기 위한 노력은 지속되어야 할 것으로 판단된다. 이는 통화관리의 유연성을 확대하는 동시에 재정투명성을 제고하기 위해 필요하다. 특히 총액한도대출의 완전한 철폐 및 한은 이익잉여금의 정부이전 축소와 더불어 국고금에 대한 이자지급을 고려하는 것이 바람직하다.

본 연구는 한국과 일본의 철도업체를 노동, 동력, 차량 및 유지보수의 세 가지 생산요소를 투입하여 신칸센 인키로, 일반여객 인키로, 화물톤키로의 세 가지 산출물을 생산하는 기업형태로 상정하여 확률적 변경 접근법을 이용한 일반초월대수 함수형태의 가변비용함수모형을 설정하였다. 이 모형의 독립변수로는 준고정요소인 기반시설의 총 가치와 네트워크효과를 나타내는 궤도연장, 타 업체와의 비용구조 차이를 반영하는 더미변수, 그리고 생산성을 분석하기 위한 시간추세변수가 함께 포함된다. 가변비용함수모형은 철도청에 대한 27개 연도별 자료($1977{\sim}2003$), 일본국철(JNR, Japan National Railways)에 대한 8개 연도별 자료($1977{\sim}1984$), 그리고 7개 일본철도주식회사(JR's, Japan Railways)에 대한 17개 연도별 자료($1987{\sim}2003$)를 결합한 총 154개의 불균형통합자료를 이용해 반복결합일반화최소자승법으로 추정하였다. 확률적 변경 접근법을 이용한 비용 효율성 추정 결과 한국과 일본의 철도업체는 표본평균에서 비용 비효율성이 2.57%로 나타났으며, 비용 효율성은 평균적으로 JR서일본이 가장 높고 JNR과 JR구주가 가장 낮은 것으로 분석되었다. KNR의 경우 $1977{\sim}2003$년까지 평균적인 비용 비효율성은 1.80%이고, 특히 $1996{\sim}2000$년에 비용 비효율성이 4.16%로 가장 컸던 것으로 나타났다. 반면 일본의 경우 민영화 이후 비용 비효율성이 전반적으로 상당히 개선된 것으로 나타났다. 한편 비용 효율성 변화, 기술변화, 규모 효율성 변화 및 배분적 효율성 변화에 기인하는 생산성 변화율을 추정한 결과 전반적으로 정부부처형 공기업인 KNR과 공사체제인 JNR의 생산성은 감소한 반면, 민영업체인 JR's의 생산성은 JR동해를 제외하고 증가한 것으로 나타났다.

Purpose - Because creativity, which is an intangible resource embedded within the company, can offer a competitive advantage, most companies have an interest in promoting creativity among their employees and division(e.g., marketing organization). Creativity renders a sustainable competitive advantage to a firm because it is a strategic resource that is valuable, flexible, rare, and imperfectly imitable or substitutable. Although most companies broadly recognize the importance of creativity, the methods for developing creativity remain elusive. Therefore, the present study investigates how to structure incentives to motivate employees to be more creative and how to develop tools to facilitate creativity. In detail, the present study aimed to examine the relationship between the regulatory focus of marketing organizations(e.g., promotion focus vs prevention focus) and creativity of marketing organizations. In addition, the present study set out to examine the moderating role of interaction of financial reward and creative training in addition to investigating the direct relationship between creativity and regulatory focus in New Product Development(NPD) context. Research design, data, and methodology - The data used to test the hypotheses are drawn from a survey of full time NPD project members(including project manager, designer, engineer, and marketer). The present study utilized data obtained mainly from a database compiled by the Korea Investors Service-Financial Analysis System which provides comprehensive corporate and financial information on firms listed on the Korea Stock Exchange. A study population comprising 1,000 South Korean firms was obtained from this database. We selected 864 firms from the database, and the firms have experiences of new product development project. We collected a total of 162 responses, for a 18.8% response rate. After we excluded 14 questionnaire because of incomplete responses, a total of 148 questionnaire remained(final response rate: 17.1%). Working with a sample of 148 responses in South Korea, hierarchical moderated regression is employed to test research hypotheses(

The relationship between promotion focus and creativity of marketing organization,

The relationship between prevention focus and creativity of marketing organization,

The moderating effect of joint influences(interaction between financial rewards and creativity training) on the relationship between promotion focus creativity of marketing organization,

The moderating effect of joint influences(interaction between financial rewards and creativity training) on the relationship between prevention focus creativity of marketing organization). SPSS 18.0 and AMOS software were used in the data analysis. Results - The empirical study confirmed that promotion focus of marketing organization is positively related to creativity of marketing organization. Also, prevention focus of marketing organization is positively affected to creativity of marketing organization. In addition, the interaction between financial rewards and creativity training moderated the relationship between regularity focus(e.g.), promotion focus vs prevention focus) and creativity of marketing organization. These results suggest that managers can improve the performances of their creative efforts by providing the use of financial rewards and creativity training in combination. Conclusion - Based on results of this study that examine the effects of regulatory focused creative efforts on creativity of marketing organization, promotion focus is helpful with marketing organizations to enhance their service innovation and performance. Prevention focused organization should allow monetary rewards and creativity training to increase their creativity for innovation of new products.

We examine the impact of public and private information on price movements using the thirty DJIA stocks and twenty-one NASDAQ stocks. We find that the standard deviation of daily returns on information days (dividend announcement, earnings announcement, insider purchase, or insider sale) is much higher than on no-information days. Both public information matters at the NYSE, probably due to masked identification of insiders. Earnings announcement has the greatest impact for both DJIA and NASDAQ stocks, and there is some evidence of positive impact of insider asle on return volatility of NASDAQ stocks. There has been considerable debate, e.g., French and Roll (1986), over whether market volatility is due to public information or private information-the latter gathered through costly search and only revealed through trading. Public information is composed of (1) marketwide public information such as regularly scheduled federal economic announcements (e.g., employment, GNP, leading indicators) and (2) company-specific public information such as dividend and earnings announcements. Policy makers and corporate insiders have a better access to marketwide private information (e.g., a new monetary policy decision made in the Federal Reserve Board meeting) and company-specific private information, respectively, compated to the general public. Ederington and Lee (1993) show that marketwide public information accounts for most of the observed volatility patterns in interest rate and foreign exchange futures markets. Company-specific public information is explored by Patell and Wolfson (1984) and Jennings and Starks (1985). They show that dividend and earnings announcements induce higher than normal volatility in equity prices. Kyle (1985), Admati and Pfleiderer (1988), Barclay, Litzenberger and Warner (1990), Foster and Viswanathan (1990), Back (1992), and Barclay and Warner (1993) show that the private information help by informed traders and revealed through trading influences market volatility. Cornell and Sirri (1992)' and Meulbroek (1992) investigate the actual insider trading activities in a tender offer case and the prosecuted illegal trading cased, respectively. This paper examines the aggregate and individual impact of marketwide information, company-specific public information, and company-specific private information on equity prices. Specifically, we use the thirty common stocks in the Dow Jones Industrial Average (DJIA) and twenty one National Association of Securities Dealers Automated Quotations (NASDAQ) common stocks to examine how their prices react to information. Marketwide information (public and private) is estimated by the movement in the Standard and Poors (S & P) 500 Index price for the DJIA stocks and the movement in the NASDAQ Composite Index price for the NASDAQ stocks. Divedend and earnings announcements are used as a subset of company-specific public information. The trading activity of corporate insiders (major corporate officers, members of the board of directors, and owners of at least 10 percent of any equity class) with an access to private information can be cannot legally trade on private information. Therefore, most insider transactions are not necessarily based on private information. Nevertheless, we hypothesize that market participants observe how insiders trade in order to infer any information that they cannot possess because insiders tend to buy (sell) when they have good (bad) information about their company. For example, Damodaran and Liu (1993) show that insiders of real estate investment trusts buy (sell) after they receive favorable (unfavorable) appraisal news before the information in these appraisals is released to the public. Price discovery in a competitive multiple-dealership market (NASDAQ) would be different from that in a monopolistic specialist system (NYSE). Consequently, we hypothesize that NASDAQ stocks are affected more by private information (or more precisely, insider trading) than the DJIA stocks. In the next section, we describe our choices of the fifty-one stocks and the public and private information set. We also discuss institutional differences between the NYSE and the NASDAQ market. In Section II, we examine the implications of public and private information for the volatility of daily returns of each stock. In Section III, we turn to the question of the relative importance of individual elements of our information set. Further analysis of the five DJIA stocks and the four NASDAQ stocks that are most sensitive to earnings announcements is given in Section IV, and our results are summarized in Section V.
