  • The aim of this paper is to investigate adjusting process of trade-off relationship between economic growth and income distribution in China which is established by mixed with social and market-oriented economic systems. The characteristic nature of social welfare index in urban and rural regions in China is examined by employing principal component analysis. Empirical evidences reveal that unlike national wide or urban region, the increases of income contribute to improve social well-being in rural region, but not social welfare index. Accordingly, it can be said that although social well-being in rural region seems to be harmful because of weakly organized social welfare index, the potentiality exists to improve social well-being by increased income. Taken all together, the results signifies that the mixed economic system such as China might distribute its increased income appropriately, however, the distributional system is hardly operated to improve social welfare index. And thus the distributional system has to be amended to enhance social well-being in China.

  • We analyze the economic effects of mobile termination rate asymmetry by simulation model. The asymmetry allows the mobile operator to get access profits at the expense of the incumbent and induces negative effects such as the entry of inefficient operator and allocative efficiency as well as productive efficiency. We use simulation model to investigate the effect on social welfare of asymmetric regulation. If the brand loyalty is high, social welfare increase as the termination charge of entrant increases. The extension of the basic model shows that the degree of social welfare increase becomes higher as the brand loyalty increases when the cost of entrant is smaller than that of incumbent. But, the degree of social welfare decrease becomes lower as the substitution effects increase.

  • The aim of this study is to analysis how economic welfare lost happens within the present korea seasonal and time period electricity pricing system and find out reasonable electricity price system acceptable during the transitional period of korea electricity industry restructuring To analyze economic welfare lost in the electricity industry, in advance seasonal and time periodic 9 demand curves(summer, spring &fall, winter/peak-load time, middle-load time, low-load time) and one market supply curve are made and then using these demand and supply curve, seasonal and time periodic market equilibrium prices is calculated. Finally, comparing these market equilibrium prices with present regulated classified seasonal and time periodic prices, the whole economic welfare lost in the electricity industry is calculated. The result of this study shows that in 2002, the total economic welfare lost in electricity industry is 137,770 million Won and under present price system, the worst welfare lost is happening seasonally in spring & fall, time periodically in the middle-load time. Specifically analyzing the characteristics of welfare lost, especially on the industry customers and service customers which are applied in seasonal and time periodic pricing, for the industry customers, the welfare lost calculated in this class occupies 51% of the total welfare lost in the whole electricity industry and the worst welfare lost is happening seasonally in spring & fall, time periodically in the middle-load time. For service customers, the welfare lost calculated in this class occupies 13% of the total welfare lost in the whole electricity industry and the worst welfare lost is happening seasonally in summer, time periodically in the peak time Finally, this study was made based on the year of 2002 and KEPCO has practiced two times of rate change until now. The result of rate change was positively analyzed in the direction of economic welfare improvement(welfare improvement achieved by 16.3% compared to 2002 result).

  • 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.

  • 본 논문에서는 카페테리아 복리후생의 기본개념의 고찰과 함께 국내 및 국외에서 활용되고 있는 카페테리아 플랜에 대한 사례연구를 통해 A항공사(航空社)를 중심으로 새로운 종업원 복리후생제도 도입을 제시하고자 한다. 복리후생제도 도입방안은 다음과 같다. 첫째, 선택적 복리후생제도에 대한 종업원들의 공감대를 형성하는 것이다. 항공사는 대체로 노동조합이 잘 발달되어 있는 편이고 종업원들의 학력수준도 높은 편이다. 따라서 사내교육 등을 통하거나 노조 설명회를 통하여 전반적인 사회변화에 따른 다양한 선택적 복리후생제도의 효율성, 종업원 니즈에 대한 충족도의 우수성, 저가항공사의 난립에 따른 필연적 M&A 등이 발생할 경우를 대비하여 필요하다는 점, 종업들의 원가에 대한 이해(cost contiousness)가 높아질 수 있다는 점, 등에 대해 알리고 이해를 시킬 필요가 있다. 둘째, 기존에 일률적으로 제공되고 있는 우대탑승제도는 종업원마다 매년 일정한 한도가 부여되지만 티켓을 소비하는 횟수는 각각 다르다. 또한 항공업의 특성상 성수기로 인해 원하는 시간에 원하는 곳을 갈 수 없다는 큰 문제점이 발생하고 곧 니즈 욕구에 대한 불만족으로 직결 한다. 우대탑승 제도에 부여된 항공 티켓 지원은 비수기나 여유 있는 좌석상황에 따라 소비할 수 있기 때문에 종업원의 만족도는 높지 않게 나타난다. 따라서 종업원의 수혜수준을 종업원이 스스로 선택할 수 있게 함으로써, 사원 스스로의 니즈에 맞게 복리후생 계획을 세울 수 있게 하는 카페테리아플랜 즉 선택적 복리후생제도의 도입의 검토가 필요하다. 이런 선택적 복리후생제도는 종업원의 측면에서 좀 더 자신의 상황과 요구에 부합하는 복리후생을 수혜함에 따라 만족도가 증가하고, 스스로 복리후생을 선택함으로써 동기를 부여하는 측면의 의의가 있다. 그러나 현 기업의 능력과 종업원 의식에 대한 정확한 분석 및 이해가 없는 외부 성공사례의 도입은 지금까지 우리나라 많은 기업들의 경영기법 도입사례와 같이 일과성으로 끝나는 위험성도 크다. 따라서 보다 깊은 자기 성찰을 통한 제도의 수용과 이를 부분적으로 개선 및 보완하여 적용할 줄 아는 지혜가 무엇보다도 우선되어야 할 것이다.

  • This paper constructs the two-part tax-a combined form of output tax and entrance fee-for polluting oligopolists under endogenous entry. In the presence of external damage that varies exogenously with aggregate output, we show that the two-part tax produces the ex post Pigouvian rule and thus achieves the first-best optimum. We also examine a detailed analysis of the impact of the two-part tax on social welfare and government revenues. Finally, when estimation errors exist in the process of regulation, we identify the incentive conflicts between interest groups and analyze the effects of estimation errors on determining optimal tax. In particular, we show that if the regulator takes care of both welfare loss and revenue gain under the proposed two-part tax, not only over-estimation on the slope of external damage but also under-estimation on the slope of market demand should be taken into the policy consideration.

  • We introduce a simple theoretical model to analyze the welfare impact of a competition policy in the natural gas market in South Korea. An incumbent monopolistic firm currently owns essential facilities, but the competition policy mandates that the firm provide open access to any entrant firm, charging an access fee. When no regulation is imposed on the fee pricing, this policy increases social welfare as well as the profit of the incumbent firm. When the pricing is regulated, however, social welfare depends on whether there is information asymmetry between the government and the firm regarding the operating cost of the facilities. If the government has complete information, social welfare can be maximized by choosing the optimal prices. Otherwise, the government has to set the prices based on the information that the firm delivers. We formulate a Bayesian game to analyze this case and identify a set of perfect Bayesian equilibria to compare social welfare.
