지금까지 사회보장제도(社會保障制度)의 경제적(經濟的) 효율성(效率性)에 대한 많은 논의가 있어 왔다. 그러나 그중 생애주기(生涯週期)(life-cycle)에 바탕을 둔 일반균형연산모형(一般均衡演算模型)(AGE : Applied General Equilibrium)에 의환 경험적 분석은 미진하였다. 본(本) 연구(硏究)의 목적(目的)은 사회보장제도(社會保障制度)의 세대내(世代內) 생애소득분위간(生涯所得分位間) 재분배효과(再分配效果)와 경제적(經濟的) 효율성(效率性)을 분석하는 데 있다. 연구방법으로서 Fullerton and Rogers(1993) 모형을 수정한 일부문(一部門), 다소비자(多消費者) 생애주기(生涯週期) 일반균형연산모형(一般均衡演算模型)을 이용하였다. 본 연구는 미국을 대상으로 한 정상상태(定常狀態)(steady state)의 분석이며, 소비자(消費者)를 생애소득별(生涯所得別)로 5분위(分位)로 나누어 기존 사회보장세(社會保障稅) 및 급여(給與)가 경제적(經濟的) 효율성(效率性)뿐만 아니라 계층간(階層間)의 분배(分配)에 어떠한 영향을 주는지를 분석하였다. 본(本) 연구(硏究)의 주요한 기여사항(寄與事項)은, 첫째 사회보장제도(社會保障制度)의 부담귀착분석(負擔歸着分析)에 새로운 연구방법(硏究方法)을 시도하였다는 점, 둘째 재정정책(財政政策)의 하나인 사회보장제도(社會保障制度)의 실질적(實質的) 부담(負擔)의 귀착문제(歸着問題)를 생애주기모형(生涯週期模型)으로 분석하였다는 점, 셋째 부담(負擔)의 귀착(歸着)은 사회보장세(社會保障稅)와 아울러 사회보장급여(社會保障給與)를 고려하여 분석하지 않으면 편향(偏向)(biased) 될 수 있다는 점을 지적한 점, 넷째 분석결과(分析結果) 기존 사회보장제도(社會保障制度)는 생애주기적(生涯週期的) 소득분배(所得分配)의 관점에서 누진적(累進的)(progressive)인 제도이지만 경제적(經濟的) 비효율성(非效率性)(efficiency cost)을 내재하고 있다는 점 등을 밝힌 것이다.

The purpose of this study were to a) clarify the current practice of internal marketing by contracted food service management companies, b) analyze the effectiveness of current internal marketing practices. The survey was conducted between October 12 and November 2, 2002 with the 10 contracted food service management companies; 6 large, and 4 small & medium sized companies. No significant difference was existed with the categories of internal marketing. However significant differences were existed with the service education, sanitary education, periodic interviews, rewards for best employees, incentive payments, paid -leave allowances, job function allowances, and position classes including unit manager, dietician and cook of MBO. The actual administration of internal marketing strategies showed that, the significant differences were existed with education, paid-leave, and employee welfare systems among position classes. Also the significant differences were existed with all categories of internal marketing between large and small & medium sized companies. In general, small & medium sized companies score of the internal marketing performance was lower than that of large sized companies. Therefore, the segmented internal marketing strategies depending on the analysis not only demand for employees but also the size of company, were required to be an effectively and efficiently managed contracted food management companies.

The ship management industry in South Korea has been growing steadily, leading the government to implement policies to support its development in response to changing environmental conditions. These policies aim to improve the competitiveness of South Korea's ship management industry by recognizing the importance of skilled professionals in determining its success. Plans and policies have been put in place to cultivate these professionals, but ship management companies are currently facing a serious shortage of manpower. To enhance the industry's competitiveness, it is essential to attract and retain competent ship management professionals. Therefore, this study investigates the reasons for turnover among these professionals. The research results identified four factors contributing to turnover: Work Environment, Economic Compensation and Welfare Benefits, Self-Development, and Promotion and Career Advancement. Subsequent multiple regression analysis based on these factors revealed the need to strengthen economic rewards and benefits in order to reduce turnover rates among ship management professionals. This study provides foundational data for the development of stable human resource management policies for the future of the ship management industry.

치수사업에서 실시하는 경제성분석은 계획하고 있는 사업의 사회적 후생의 극대화 측면에서 경제적 타당성을 분석 평가하는 것으로서 일반적으로 편익${\cdot}$비용분석이 사용되고 있다. 이러한 경제성분석시의 문제점으로 직접편익뿐 아니라 간접편익 및 비계량편익에 해당하는 사업의 효과도 편익부분의 계산에 포함할 수 있는 방법이 필요한 실정이다. 이에 따라 본 연구에서는 홍수에 의한 교통두절로 인한 피해를 간접편익으로 고려하여 오산천지역에 적용해 보았다. 교통두절피해 편익의 항목으로서 주로 차량운행비용 절감과 통행시간비용 절감의 두 항목을 고려하였으며, 이 두 항목에 내한 결과에서 홍수지체시간당(단위 1일당) 적지 않은 편익이 발생하는 것으로 나타났다. 본 연구를 통해 일반적인 치수사업 경제성분석에서 이뤄지지 않았던 교통두절에 의한 피해항목을 간접편익으로 고려함으로써 홍수로 인한 교통두절피해를 정량적으로 계량할 수 있었으며, 실질적으로 편익에 영향이 가장 큰 편익가치(재화가치, 시간가치)에 대한 연구가 계속적으로 수반된다면 이후의 다른 치수사업 경제성분석시에 효과적인 분석이 이뤄질 것으로 판단된다.

This study was conducted to compare job satisfaction and factors related to job satisfaction between permanently and temporarily employed dietitians in school foodservices in the Gyeongsangnam-do area. A total of 204 questionnaires were used in the final analysis. The average age, length of employment, and monthly wage of temporarily employed dietitians was significantly lower than those of permanently employed dietitians. However, there was no significant difference of overall job satisfaction between permanently and temporarily employed dietitians, although the average pay, welfare benefits, and promotion factors for permanently employed dietitians was significantly higher. Work and pay factors had significant effects on the overall job satisfaction of permanently employed dietitians, while work factors and work atmosphere had significant effects on the overall job satisfaction of temporarily employed dietitians. In conclusion, there was a significant difference in overall factors related to job satisfaction between permanently employed dietitian and temporarily employed dietitians. The pay, welfare benefits, and promotion condition of temporarily employed dietitians should be improved to ensure the efficient management of the school foodservice workforce in the future.

This paper provides the analysis of economic theories about bundling in telecommunications service. First, the negative aspect of bundling is discussed. Second, the competitively neutral aspect of bundling which is counter response of negative effect is analyzed. Third, some variables affecting the bundling is investigated and the corresponding effect of bundling is discussed. The bundling can increase the social welfare under some circumstance while it sometimes decreases economic efficiency by detering the entry of competitive firms. Finally, regulatory approaches on bundling such as the criteria of bundling provision, the requirement of equal access, the discounting scheme ad a price control, ex anti regulation vs. ex post regulation, and the criteria of predatory pricing are provided.

This paper examines the redistributive potential of capital taxations within the two-class overlapping generations model, where only capitalists are intergenerationally linked through heritable capital stocks. In particular, the dynamic welfare incidence of two different capital taxations is examined; first a capital income tax levied uniformly on interest earnings, and second, an estate tax levied on the intergenerational transfers of capital stock within the capitalists' families. Redistributive effects are measured by examining how the permanent and unanticipated changes in proportional capital income tax and estate tax rates affect workers' welfare when the proceeds in each period are distributed, in a lump-sum fashion, among young workers. It is shown that, except for in the short run, both the capital taxes are ineffective and may actually lower the workers' steady state welfare through the shifting of tax burden toward workers from capitalists. Differential incidence analysis shows that redistributive potential is diminished further when the lump-sum transfers are financed by the estate tax rather than by the capital income tax. Although the model examined in this paper is based on simple and strong assumptions, this study suggests that redistributive policy using the capital taxations may only have distortionary effects in the long run, without improving workers' welfare, by incurring dead-weight loss unless additional fiscal measures are implemented to increase the investment incentives.

In Korea, various environmentally harmful subsidies are granted in agriculture, fishery, energy, electricity, transportation, steel and shipbuilding industry. Examples include tax-exempt fuel for agriculture & fishery, VAT- exemption for briquette & anthracite, temporary subsidy for fuel, production stabilizing subsidy for coal mining, subsidy for briquette. Korea's yearly total subsidy in energy area is about 5,291 billion won, among them is 4,870 billion won. To reduce air pollutants and to mitigate climate change, Korea has to review the phase-out of environmentally harmful subsidies and the phase-in of environment-friendly subsidy. The reduction or removal of environmentally harmful subsidies will enhance economic efficiency and bring about environmental benefits. Economic efficiency means less use of inputs, which reduces environmental cost and improves social benefits. This paper applies the Shoven and Whalley's model to the Korean economy and analyzes the general equilibrium incidence effects of reforming environmentally harmful subsidies in the energy and electricity in Korea. We consider several counterfactual scenarios in which current environmentally harmful subsidies are reduced or abolished, compare them with the reference case in the economy, and evaluated the change in efficiency costs and distributional incidence of tax reforms related to subsidies.

The objective of this study is to conduct a quantitative assessment of potential impacts on the Korean economy of Agreement on Trade in Services Under the Framework Agreement on Comprehensive Economic Cooperation Among the Governments of the Republic of Korea and the Member Countries of the Association of Southeast Asian Nations which was signed on 21 November 2007 using a Computable General Equilibrium (CGE) model. Tariff equivalents of services were calculated on the basis of concessions made in the Agreement between Korea and ASEAN member countries. The empirical analysis shows that Korea is to get an additional gain in real GDP of 0.04 percent and in welfare of US$106 million, with an increase in per capita utility of 0.03 percent. Total exports and imports of Korea are to rise by US$179 million and $191 million, respectively, causing a trade deficit of $12 million. Korea's exports to ASEAN member countries will increase by $108 million and Korea's imports from them will rise by $278 million, giving rise to a trade deficit of $170 million.

본(本) 연구(硏究)에서는 가계(家計)가 소비지출시 어느 정도 유동성제약(流動性制約)(liquidity constraint)하에 처해 있는가를 분석하기 위하여 이론적인 모형(模型) 제시와 함께 한국(韓國) 일본(日本) 미국(美國)을 대상으로 실증분석(實證分析)을 시도하였다. 3개국 공히 내구재(耐久財) 소비지출시 비내구재(非耐久財) 소비에 비해 상대적으로 유동성제약 현상이 더 심한 것으로 추정되었다. 특히 우리나라의 소비자들은 내구재와 비내구재 등 모든 형태별 소비지출에 있어서 일본(日本)과 미국(美國)에 비해 더 심한 유동성제약하에 처해 왔던 것으로 나타났다. 1980년대에 들어서는 소비자금융시장에서의 유동성제약(流動性制約)이 점차 완화(緩和)되어 온 것으로 나타났으나, 여전히 일본과 미국의 수준을 크게 상회(上廻)하였다. 이러한 추정결과들은 장기간에 걸친 생산자(生産者) 중심의 금융제도 및 관행 등으로 인해 우리나라의 소비자금융시장(消費者金融市場)이 선진국에 비해 낙후(落後)되어 있음을 반영한다. 위의 분석결과는 향후 할부금융제도(割賦金融制度) 도입 등 소비자금융 규제 완화가 본격화되면 유동성제약(流動性制約)이 완화되어 가계의 차입(借入)과 저축(貯蓄)을 통한 소비의 평탄화(平坦化)(smoothing)가 가능해짐으로써 소비자의 후생(厚生)이 증대되고 경기변동(景氣變動)의 진폭이 축소될 것임을 시사한다. 또한 소비자금융의 활성화는 기존의 유동성제약하에 처해 있었던 가계들의 소비를 촉진시켜 단기적으로는 경제 전체의 저축률(貯蓄率) 하락요인으로 작용할 가능성도 있을 것이다.
