The study analyzes how effective the Government Internship Program has been on accumulation of the human capital. The Program was designed under the foreign exchange crisis to support the new, but unemployed graduates with MA or Ph.D degree in the science and the engineering fields. The survey data is collected from the participants in the Program. The Tobit model is estimated to find the economic effects of the Program in terms of the rate of return of investment in the human capitals of the intern researchers. Considering that the Program is tentative and that the human capitals of the participants are easily obsolescent, the rate of return is observed to be substantially large. These results imply that the Internship Program has been successful in terms of providing not only the researchers with the opportunity to accumulate the human capital by means of the on-the-job-training, but also the institutes or the firms with the opportunity to utilize the high-quality researchers at the low cost.

This study explores a changing social expenditure structure of welfare states on new social risks, using logistic regression analysis with Panel Corrected Standard Errors Model on panel data of 1997-2007 years from 27 OECD nations. The result of this study presents that social expenditure structures have been adjusted with new social risk structure due to trade openness, female employment rates, and child population rates. Greater trade openness, higher women's employment rates, and lower child population rates are, more social investment expenditures are than income security expenditures. Rates of employment in service industries and elderly population rates are not statistically significant on the change of social expenditure structure. This result does not imply a complete switch from demand-based to supply-based social policy, but somewhat reflects transitions of a social welfare system for changing economic and social environments in order to sustain welfare state economically.

Research and Development(R&D) investment is an issue of central importance in any economy. In this paper we analyze the relationship between R&D spillovers and trade-related variables, using a two-stage model where duopolists simultaneously decide on R&D in the first stage and engage in Cournot competition in the second stage. We characterized and compared the free-trade and trade-restriction R&D equilibrium in a two-stage game of R&D investment followed by Cournot market competition. We also assessed the impact of varying the R&D spillover on the equilibrium outcomes and tariff. We showed for both free trade and protection cases that there exists a unique symmetric solution(subgame perfect Nash equilibrium). As the solution, while analytical, cannot be stated in closed form, we resorted to numerical experiments to investigate the equilibrium results. Our estimates indicate for both free trade and protection cases that the level of R&D investment and the rate of R&D expenditure decrease as the degree of R&D spillovers increases, and that there is an inverse relation between the degree of R&D spillovers and level of protection. The latter implies that the larger the degree of R&D spillovers, the lesser the level of protection.

Domestic construction companies are interested in finding a larger market abroad because of declining the amount of orders placed and competing the amount of orders received. Recently, the Development project including the finance offer by builder is becoming more common and broad in the flow of the world market in construction from underdeveloped countries to the advanced countries. If the construction companies revitalized because of being active in the Middle East market don't appropriately cope with the situation, they will be probably depressed. The support policies helped revitalization of the development project are examined in this study. The purpose of this study is basic data how to be influenced by the situation of market abroad, policies revitalized development project and extending market. The policies revitalized development project and the relationship of many variables near the market abroad are analyzed applying the System Dynamics as hopeful market abroad which have a circumstance finding a larger market.

This research confirms a non-linear relationship between R&D investment and performance of small and medium-sized enterprises and measures the adequate level as threshold value. Although previous studies did not consider the time lag and estimated indirectly the level using the R&D investment squared term, this study assumes 2 years time lag and uses the threshold estimation model to measure directly. We find that there is the S-curve relationship between the profit rate as R&D output and R&D intensity and the ratio of researchers to employees as R&D input. Also, we estimate the adequate levels of R&D investment, 6.4% for R&D intensity and 13% for the ratio of researchers to employees. This relationship and measurement of the level can offer basic facts and implications about R&D policy and strategy.

The objective of this study is to investigate the association between MBTI personality types of potential investors and their cognitive behavioral investment disposition. Three questionnaires related with MBTI, cognitive investment disposition, and behavioral one from 400 subjects were collected and analyzed. Based on both cognitive and behavioral investment disposition scores, potential investors having E(Extroversion), S(Sensing), and F(Feeling) types tend to put up with the risk resulting from their investment better than ones who having I(Introversion), N(Intuition), and T(Thinking) types. However, the difference between J(Judging) and P(Perceiving) types was not significant. Also investor group with ENF combination had the most aggressive investment disposition among other groups. On the contrary the group with ISF had an tendency to avoid the investment risk. In addition the correlation between cognitive and behavioral investment dispositions was 0.86. This study is expected to be used as basic data with which investment companies and banks recommend adequate financial instruments to consumers.

정보 통신 기술은 비즈니스를 변화시켰고, 이제 교육에도 영향을 미치고 있다. e-Learning으로 대변되는 교육의 변화는 교육의 패러다임을 변화시키고 있다. e-Learning은 현재 정부차원에서 적극적인 지원을 하고 있는 상태이고, 시장 규모 및 성장 가능성이 매우 높다. 그러나 아직 시장이 성숙되어 있지 않고 기업환경이 불확실하기 때문에 e-Learning 시장 참여자들의 본격적인 투자 활동은 미진한 수준으로 보인다. 이에 본 연구는 e-Learning에 대한 특징을 살펴보고 국내외 산업 현황 및 정책 방향을 분석하여 e-Learning에 대한 현안과 문제점을 진단하고 발전 방향을 제시하고자 한다.

전원개발계획은 단독으로 결정되는 것이 아니라 국가경제운용정책 및 에너지 정책과 더불어 전력회사의 요금정책, 부하관리, 재무계획, 전원입지, 송전계통계획 등과 연계되어 결정되어야 한다. 기존의 전원개발계획은 주어진 수요예측안을 이용하여 수요를 기준신뢰도 범위내에서 최소비용으로 만족시킬 수 있도록 전원설비투자를 결정하는 것이었으나 향후로는 부하관리정책을 포함한 수급계획(supply-demand planning)의 수립기법, 미래 수용와 연료 가격등 경제요인의 불확실성 및 환경규제 등의 요인을 감안한 전략계획기법(strategic planning) 그리고 재무계획 등 관련계획 업무를 포함하는 종합계획 모형(corporate planning model)의 구축에 대한 방안을 강구해야 할 것이다.

This study investigates the welfare implications of BTL projects using a general equilibrium model with the public sector and public-private partnerships. We show that when the government is not allowed to run budget deficits but private firms is able to overcome the financial constraint, BTL projects performed by public-private partnerships (PPPs) could be a good alternative and improve the welfare of the model economy. This paper quantitatively investigates excessive expansion of PPP projects and several alternatives to retrieve welfare losses caused by such an expansion. Assuming that future rents of BTL projects are not taken into account, we find the welfare losses up to 20 percent relative to conventional government projects. Finally, we show that it would be possible to reduce the losses by transforming the fully depreciated capital stock of the government projects into much smaller new PPP projects.
