This study aims to analyze the influence relationship between the level of fringe benefits and relational contract among social workers in the non-profit organization. Under this relationship, we explored the dual mediating effect of perceived superior's support and perceived organizational support. A total of 371 self-administered questionnaires were distributed to social workers in Gwangju, South Korea, and 271 questionnaires (73.0%) were used for study analysis after excluding incomplete and unreliable responses. This study performed structural equation modeling, the results are as follows. Perceived superior's support and perceived organizational support both have a positive (+) influence on relational contract. Furthermore, perceived superior's support and perceived organizational support were found to mediate effect between fringe benefits and relational contract. Therefore, these results contribute to provide academic meaning that the range of future studies by identifying the dual mediated effect of the fringe benefits and social worker 's relational contract.

The land use-transportation models typically have complicated model structure that is good for empirical execution but bad for theoretical probe. This complexity makes it very difficult to derive the first-order conditions for system optimization in tractable forms. Yu and Rhee (2011) and Rhee (2012) show how to simplify the derivative of the model's objective function with respect to policy variables in the computable general equilibrium model of land use and transportation. However, the travel demand in their model was fixed. This drawback fundamentally limits the applicability of their methodology in the planning field. We relax this restriction. Once this is done, we can employ the methodology developed in analyzing the impacts of various types of policy instruments in the models where land market is treated endogenously and transportation network is embedded.

본(本) 연구(硏究)에서는 1984년 한 해의 "도시가계연보(都市家計年報)"(전산(電算)테이프자료(資料))를 이용해 도시가구(都市家口) 계층간(階層間) 및 계층내(階層內)의 소득(所得) 및 소비(消費) 후생불평등도(厚生不平等度)를 추정하였으며 그 요인(要因)을 근로소득(勤勞所得)의 측면(側面)에서나 찾아보았다. 본(本) 연구(硏究)의 주요실증분석(主要實證分析) 결과(結果)는 다음과 같다. (1)도시가구(都市家口)의 불평등(不平等)을 크게 좌우(左右)하는 것은 재산소득(財産所得) 유무(有無)이며 (2)근로소득(勤勞所得)의 불평등(不平等)은 주로 학력간(學歷間) 임금격차(賃金格差)에서 비롯되고 있으며 (3)재산소득(財産所得)의 불평등(不平等)은 자본이득(資本利得)(capital gain)을 좌우(左右)하는 일반물가수준(一般物價水準)의 불안정(不安定)에서 비롯되고 있다. 따라서 불평등(不平等)의 개선(改善)을 위해서는 무엇보다도 먼저 물가수준(物價水準)의 안정(安定)이 최우선 조건이며 이와 더불어 학력간(學歷間) 임금격차(賃金格差)를 완화(緩和)시키는 노력도 병행되어야 할 것으로 보인다.

아세안은 한중일과의 무역을 통한 경제적 연계의 심화현상과 최근 글로벌 위기로 인한 경기침체를 고려하여 새로운 경제성장추진을 위해 동북아의 한중일 삼국과의 무역자유화를 적극 추진하고 있다. 이미 ASEAN-중국, ASEAN-일본, ASEAN-한국 양자간 자유무역협정(FTA)이 발효되어 실행되고 있으며, 이들 3개 양자협정을 아우르는 A+3FTA(ASEAN+중국+일본+한국) 논의도 진행중이다. 이에 본 연구는 이들 4개 자유무역협정의 경제적 효과를 분석하여 과연 A+3FTA가 아세안은 물론 동아시아 역내에서 보다 바람직한 통상정책인지를 평가한다. 본 논문의 정성적 평가는 기존의 경제통합의 경제적 효과를 결정하는 이론에 근거하여 참여국의 제반 경제적 현황(경제규모, 소득수준, 경제개발수준, 거래비용, 무역 및 산업구조, 관세율 등)을 통계적으로 비교 분석한다. 한편 정량적 평가는 무역의 경제적 파급효과 분석에 널리 이용되고 있는 연산가능한 일반균형모형(CGE)분석방법을 적용한다. 정태적 효과의 분석을 위해서 GTAP 모형을 이용하며, 이와 더불어 동태적으로 투자를 통한 자본축적을 반영하는 자본축적 CGE 모형분석을 병행한다. 분석결과 후생 및 생산확대 측면에서 아세안의 경우 일본과의 양자간 FTA가 한국이나 중국과의 FTA에 비해 보다 긍정적인 후생증진을 가져올 것으로 기대되며, 아세안과 한중일 모두에게 A+3FTA가 동아시아 역내에서 보다 바람직한 자유무역협정이 될 것으로 평가된다.

Terms of trade shocks have been considered one of the main driving forces causing business cycle fluctuations in small open economies. Despite their importance in business cycles of small open economies, it is hard to find a serious study in existing literature investigating their implications on monetary policy under a small open economy. Considering it, this paper studies what form of monetary policy rule is the most adequate for a small open economy where terms of trade shocks are dominant factors in generating its business cycle fluctuations. For this purpose, various implementable monetary policy rules frequently analyzed in existing literature are compared in terms of social welfare levels which they can provide for the economy respectively. Main results of this paper can be summarized as follows. First, for a small open economy where terms of trade shocks are main driving forces of its business cycle fluctuations, the nontradable goods price inflation targeting can provide higher level of social welfare than other traditional monetary policy rules such as the CPI inflation targeting or the fixed exchange rate regime. Second, the social welfare improvement of the non-tradable goods price inflation targeting is more apparent when export goods price shocks are more important than import goods price shocks.

전 세계적으로 항공시간 전략적 제휴가 확대되고 있는 가운데 우리나라의 국적항공사들도 2001년 대한항공이 SkyTeam에 가입하였고, 2003년 아시아나 항공이 Star에 가입하였다. 그러나 국내에서 독점금지예외조항이 없어 양 항공사가 전략적 제휴 그룹 내에서 일부 활동에 제약을 받고 있는 것으로 추정된다. 미국은 항공자유화 정책의 확대 추진 전략에 따라 미국 항공사들이 외국항공사들과 전략적 제휴를 맺는 경우, 자국의 시장에서 독점금지법 조항을 면제시켜주는 제도를 실시하고 있다. 이제도로 인하여 외국 항공사들과 폭 넓은 협력 관계를 유도하고 경쟁력 있는 항공운송산업을 이끌어 가고 있다. 본 연구는 미국의 독점금지예외(ATI ; Anti-Trust Immunity)에 대한 분석을 통해 국내환경에 적용 가능한지를 살펴보고자 한다. 과거 우리 정부는 경제성장을 위해 소비자로부터 생산자에게로 경제 잉여를 집중시키는 정책을 취하였다. 개발연대 동안 우리 기업은 정부의 정책 및 제도의 도움으로 또는 묵인 하에 국내시장에서 독과점적 지위를 유지하곤 하였다. 그러나 80년대에 접어들면서 “독점규제 및 공정거래에 관한 법률”과 공정거래위원회의 발족으로 시장구조를 경쟁적으로 만들고, 소비자 후생을 증대 시키는 정책목표가 보다 중요시 되고 있다. 그러나 미국에서도 소비자 후생을 증대 시키는 정책목표가 보다 중요시 되고 있다. 그러나 미국에서도 소비자 후생과 시장구조를 경쟁적으로 만들기 위해 제정된 독점금지법의 과도한 적용이 오히려 소비자 후생을 희생시킨다는 지적이 제기되고 있다. 또한 최근의 마이크로소프트사의 판례를 통해서도 나타났듯이 우월한 효율성과 규모의 경제에 의한 독점력은 인정되어야 한다는 추세이다. 이러한 관점에서 국내항공사가 외국의 항공사와 전략적 제휴를 맺어 효율성을 유지하고 규모의 경제성을 가지므로 인하여 지닐 수 있는 경쟁력은 국내의 항공운송삼업의 육성차원에서 지원이 되어야 할 것으로 판단된다. 향후 정부는 국제항공정책에 대한 장기적인 비젼과 함께 국내 항공법에 독점금지예외조항을 도입할 필요가 있다고 본다.

This paper attempts to improve domestic natural gas pricing system, thereby optimizing social welfare. This is done by deriving theoretical frameworks of natural gas pricing, which make use of both Ramsey component pricing rule and Efficient component pricing rule based on the theory of marginal cost. Allocative efficiency and social welfare between gas prices derived from the three pricing mechanism, present Cost-based pricing, Ramsey component pricing rule and Efficient component pricing rule, are analysed and compared in the case study. For the city gas, allocative efficiency of Cost-based pricing is higher than that of Ramsey component pricing rule and Efficient component pricing rule. In contrast, for the natural gas consumed for power generation, allocative efficiency of Cost-based pricing is lower than the other two pricing systems. It also turns out that social welfare is improved by the prices driven from Ramsey component pricing rule and Efficient component pricing rule rather than present Cost-based pricing.

We introduced mathematical economic analysis model for understanding the fairness of charge from VoIP providers for interconnection of access network. In order to set up this model we made four assumptions predictable in the real world. Also we proposed two accounting method that is flat-rate-pricing and usage-based-pricing and tried to propose which method is more desirable to charge for interconnection on the basis of social welfare and activation of market competitiveness. The outcome of this study includes the reasonable accounting method for interconnection between telephone network and IP Phone network which is most effective to ensure the social welfare and market competitiveness

This study investigates the strategic environmental corporate social responsibility (ECSR) of polluting duopoly when two firms have different production costs and compete with prices. We then examine an endogenous timing game in choosing ECSR and its effects on environmental damage and social welfare. The followings are the main findings: First, sequential choice of ECSR is strategic complements and it provides late adopter advantage irrespective of cost difference. Second, sequential choice of ECSR is the equilibrium of endogenous timing game. In particular, an efficient firm-leading ECSR is the payoff dominance equilibrium when cost difference is significant. Finally, environmental damage and social welfare depend on the social cost of pollution. In particular, an efficient firm-leading ECSR is socially desirable when social cost is high. However, an inefficient firm-leading ECSR increases environmental damage irrespective of social cost and it reduces social welfare when cost difference is significant.
