가격상한제가 효율적으로 시행될 경우 통신사업의 생산성 향상, 신규서비스 도입촉진 등으로 보수율 규제방식에 비하여 사회후생에 긍정적 효과가 기대된다. 즉 가격상한제는 규제대상의 사업자에게 제한된 범위내에서 요금설정의 자율성을 부여함으로써, 생산성 향상의 결과를 사업자가 일부 향유할 수 있어 원가절감의 유인을 제공할 수 있다. 또한 기술발전에 따른 신규서비스 도입과 수요행태에 부응하는 다양한 요금제도의 도입을 촉진할 수도 있다. 따라서 명시적인 규제기준과 합리적인 운용절차가 설정될 경우 경쟁활성화, 요금규제의 투명성 확보 및 공정경쟁 강화 등의 효과를 기대할 수 있다.

This study surveyed and analysed the factors that affect the job satisfaction of a home appliances service engineer. The job satisfaction analysis was based on two separate branches: the satisfaction of the current position and the intention to work. As the result, it was apprehended that as far as the individual qualities of the engineer are concerned, personality is a factor that had an effect on job satisfaction. Concerning the organisational qualities, it was analysed that social support, allowances and welfare were factors that contributed largely; and concerning the work itself, it was acknowledged that the appropriateness of the work influenced job satisfaction. To conclude, it was analysed that to increase job satisfaction, it would be important first and foremost to employ employees who have extroversive personalities, to take good care of the allowances and welfare of the employees and to distribute appropriately the amount of work.

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

As the society changes, the Private Security has developed highly in a short time. However, it has brought about various problems. The best urgent problem of those problems is the wage problem. This study is examining into the difference with the wage satisfaction and devotion to organization, and analyzing influence that wage satisfaction has on devotion to organization. According to this research, the first, women appeared higher numerical value than men in satisfaction with a wage level, wage disparity, wage system and the welfare system and the highest age group is over 26 year-old. While the college graduates appeared high satisfaction with a wage level and wage disparity, the university graduates is high satisfaction with wage system and the welfare. This shows that as the scholarship is high, they think they must be getting wages higher and higher as their work result or produce. The second, in devotion to his(her) organization, the men is higher than the women. The third, the men show the high emotional devotion because the men devote to his work on his own initiative while the women show the high continuos service devotion because they are passively. The fourth, over the 26-year old group appeared high level in devotion to his(her) organization, the university graduate group appeared high level both the emotional devotion and the continuous service devotion. The long-term employed person showed the satisfaction with job position, pay grade, and career and also appeared high in devotion to his(her) organization. The fifth, as the scholarship is low, they were concerned about a wage level and wage disparity but, as the scholarship is high, they were concerned about the wage system and the welfare. The wage satisfaction has influence on the scholarship, job position and career therefore, the long-term employed persons showed high wage satisfaction and devotion to his(her) organization. In conclusion, for the development of Private Security and high devotion to organization, the wage level of private security guards must be systematize and the quality of the welfare must be improved. And the many factors about the wage and welfare must be studied and analyzed to occupy as one of the skill lists through the educational-industrial collaboration.

This paper formulates the methodologies to estimate optimal congestion tolls from long-run and short-run perspectives and applies them to the highways of Seoul. An optimal long-run congestion toll is estimated with an optimal volume-capacity-ratio to minimize the total costs which consist of two components: road construction and maintenance costs and traveler costs. By contrast, an optimal short-run congestion toll is estimated with a supply-demand equilibrium which is determined by using a speed-flow function and a disaggregate modal choice model. The results of a long-run analysis for the Seobu urban expressway suggest the optimal volume-capacity-ratio of 1.35 and the optimal congestion toll of 503 Won per automobile kilometer. By contrast, those of a short-run analysis for the Mia-ro urban arterial suggest 1.31 and 420 Won, respectively. Although our results are to some degree dependent on the interest rate and time value assumed, one basic conclusion holds up: the congestions toll tested could generate substantial gains in social welfare if applied to Seoul.

The current linear programming model as for city park planning has the following intrinsic constraints. First of all, it cannot explicity consider choice behaviors of people. Secondly, the objective function of linear programming model cannot sufficiently intergrate satisfactions of people. In order to overcome these weak points of linear programming model, the following extensions have been made in this paper. First of all, bionominal and multinominal logit models based upon logit models, utility maximization of people have been constructed, Secondly, based upon logit models, social welfare function has been constructed in order to aggregate satisfactions of people. By doing this, intrinsic oonstraints of linear programming model have been successfully overcome. In the future research, empirical study of the model developed in this paper will be necessary. By doing this, the construction of optimal investment plan for city parks will be possible.

America is traditionally friendly to South Korea. Last year in 2008, U.S. exports to South Korea totaled $32.4 billion. The U.S. and Korean must reciprocate economic exchange. The purpose of this study to measure the re-purchase intentions and product satisfaction in America image. The major result of article can be summarized as follows. The factors of this article have been divided into 'society safety', 'industrialization level', 'economic image', 'political image', 'cultural image', and 'the character of a nation'. In the empirical result of the article, the goods satisfaction for America country image would be shown in the results. The first, 'society safety', 'industrialization level', 'the character of a nation' are significantly positive statistically to goods satisfaction. The second, 'economic image', 'political image', 'cultural image' are not as significantly positive statistically speaking.

본 논문에서는 오염배출 기업의 도덕적(道德的) 해이(解弛)(moral hazard)를 고려한 규제자의 강제정책(enforcement)에 관하여 분석한다. 또한 환경규제위반의 경우 일반적인 범죄와는 달리 의도적인 위반 이외에도 기술적 한계에 의한 불가항력적인 위반의 가능성이 있으므로 이를 고려하여 기업의 행태를 분석한다. 규제자의 강제 수단은 벌칙의 수준과 벌칙이 주어지는 기간으로 나누어 볼 수 있다. 벌칙의 강도와 벌칙이 주어지는 기간간의 관계는 사회후생을 고려한 경우 독립적이지 않고 서로 trade-off의 관계에 있다. 따라서 규제자는 벌칙의 구조를 결정함에 있어서 이러한 관계를 고려하여야한다. 크게 두가지의 선택이 있을 수 있는데 하나는 높은 수준의 벌칙과 짧은 벌칙 기간이고 다른 하나는 낮은 수준의 벌칙과 긴 벌칙 기간이다. 본 논문에서는 벌칙이 사회에 미치는 왜곡을 고려한 최적 벌칙 구조에 관한 분석을 목적으로 한다.

댐으로 인한 인공호수는 주위의 지역사회는 물론 타지역으로부터의 친수공간으로 활용될 수 있는 충분한 여건을 가지고 있음에도 불구하고 여러 가지 법적인 규제로 인해 극히 제한적으로 활용되고 있는 실정이다. 본 연구는 댐 호소의 관광자원화를 통한 친수공간의 확보와 국민복지증대 및 지역사회의 경제발전을 함께 도모할 수 있는 방안을 모색하였다. 만약 댐 호소에 대한 규제완화가 환경적인 영향이 크지 않고 경제적인 가치가 크다면 현 제도의 개선은 국민후생의 증대효과와 비점오염원의 관리를 통해 수질개선효과에 영향을 미칠 수 있음을 제시하였다.
