지식정보산업은 한정된 물리적 자원을 기반으로 한 기존 산업과는 달리 요소투입이 무한해 규모와 경험의 축적을 통한 가속적인 성장이 가능한 신산업이다. 새로운 기술적 지식을 근거로 세계 지식정보 산업의 주도권을 확보할 수 있다면 경제발전의 새로운 성장동력을 얻는 계기가 될 것이다. 지식기반경제에 능동적으로 대처하면서, 지식기반사회에서의 지식정보 관리정책 방향 수립의 기초자료를 확보하기 위해서 국가경제에서 차지하는 지식정보의 지위와 역할이 규명되어야 한다. 이에 본 연구는 지식정보의 가치 추정을 위한 체계적 연구의 기초작업으로써, 지식정보의 개념을 정립하고 지식정보의 가치를 측정할 수 있는 방안을 수립하고자 한다. 아울러 지식정보의 가치에 영향을 미치는 요인들을 도출하고 각 요인별 측정 방안에 대한 연구를 수행하고자 한다. 분석결과 지식창출형 지식정보가 소비지향형 지식정보에 비해 더 큰 가치가 있는 것으로 나타났으며 이러한 경향은 전문가일수록 두드러진 것으로 나타났다. 지식정보평가에 대한 틀이 잡히고 평가 결과가 시장으로부터 신뢰성을 획득하기까지는 정부의 적극적인 지원이 필요하며, 이는 지식정보 거래시장의 성숙과 새로운 성장동력의 확보로 이어질 것이다. Unlike existing other industries, the knowledge-based industry has the potential to grow increasingly with factor input unlimited. Importance of investigating knowledge and information evaluation cannot be overemphasized to promote economic development in that knowledge and information is accepted as an engine of new economy. We attempt to define the scope and value of knowledge and information and develop the knowledge and information value model. The results help policy-makers to manage and evaluate the knowledge and information with useful and responsible information.

Evaluating the sources of economic development is of obvious importance, and numerous attempts have been made to judge the impact of many different factors on economic development. Since some empirical studies have reported that telecommunications investment is one of the important factors in economic development, this paper empirically investigates the impacts of telecommunications investment on economic development using a cross-country analysis based on data from 56 developing countries for the year 1970-98. To this end, a further augmented version of the neoclassical Solow growth model is suggested and applied. Subject to the appropriate caveats, the results provide further support for several key conclusions of the former studies - investment in physical capital, population growth, and the human capital seem to be quite important in accounting for economic development in developing countries. In addition, more importantly, it is concluded that telecommunications investment significantly contributes to economic development in developing world.

Deep sea water (DSW) generally refers to sea water from a depth of more than 200 meters. Recently, the utilization of DSW is receiving much attention due to its high productivity, large quantity, and potential for recycling energy. In order to develop and manage the DSW, long term estimation of its demand is widely asked, but empirical work of demand analysis on the DSW products remain scarce. This study attempts to estimate the demand for the DSW products employing the data from a survey of 500 persons in the Metropolitan area (Seoul, Kyungki, and Incheon). We classified the DSW products into bottled drinkable water, soft drinks, alcohol, cosmetics, bean curd, salts, and bathing supplies. The demand for the seven DSW products was estimated for the Metropolitan area and then expanded to the nation. The annual demand for each DSW product in 2018 is estimated as 80.6, 452.6, 537.9, 158.5, 91.8, 187.8, and 392.2 billion wons in 2006 constant value, respectively. Thus, the annual DSW products market size amounts to 1,902.6 billion wons. These quantitative information can be usefully utilized in the policy-making for the industrialization of the DSW.
통일세에 대한 지불의사액 -1998년 대우패널 데이터 분석을 중심으로-

본 논문은 1998년도 대우패널 데이터를 이용하여 통일세에 대한 지불의사액(WTP, willingness to pay)을 분석하면서 평균 WTP에 대한 추정치를 얻고자 한다. 특히 상당한 수의 응답자들이 제공한 영의 WTP 자료를 다루기 위해, WTP 분포에 대한 혼합모형을 제안하고 적용한다. 혼합모형에서 WTP는 영에서 점 질량을 갖는 한 개의 분포와 실수의 양의 영역에 걸치는 다른 한 개의 분포의 혼합으로 정형화된다. 추정된 연 평균 WTP는 1인당 약 5,765원이었다. 이 값을 18세 이상 성인인구에 대해 확장시키면 연간 약 1,946억원에 이른다. 아울러 공변량을 포함한 분석도 병행하였는데, 영의 WTP를 가질 확률은 몇 개의 변수에 따라 유의하게 변함을 발견하였다. 마지막으로 연구결과에 대해 논의한다. This paper analyzes the willingness to pay (WTP) for inter-Korean unification tax and obtain an estimate of the mean WTP, using the data collected from a nationwide 1998 KHPS survey. To deal with zero WTP responses a considerable number of people gave, a mixture model of WTP distributions is proposed and applied. The WTP is specified as a mixture of two distributions, one with a point mass at zero and the other with full support on the positive half of the real line. The mean annual WTP for inter-Korean unification is 5,765 won (US$4.43) per person. The aggregate value to Korean people is 194.62 billion won annually. addition, when covariates were added to the model, it was found that the probability that an individual has zero WTP significantly varies with some variables. Finally, some discussions of the results are presented.
Information Technology and Economic Growth

Evaluating the sources of economic growth is obviously important, and numerous attempts have been made to judge the impact of many different factors on economic growth. Since some empirical studies have reported that information technology (IT) is one of the important factors in economic growth, this paper empirically explores the impacts of IT investment on economic growth using a cross-country analysis based on data from 86 countries for the year 1970-98. To this end, a further augmented version of the neoclassical Solow growth model, explicitly including IT investment, is proposed and applied. Subject to the appropriate caveats, the results provide further support for several key conclusions of the former studies investment in physical capital, population growth, and the human capital are important in accounting for economic growth across countries. More importantly, it is concluded that IT investment significantly contributes to economic growth. In addition, the main finding is that the implied return to IT investment is very high between the sample countries.
