Previous studies show that tall people have better labor market outcomes, but controlling for their abilities reduces the size of height effects. This implies that a failure to properly control for one's ability could overestimate the OLS estimate. This paper contributes to the literature by being the first to control for individual fixed effects (FE) and to examine height effects on the probability of one's attaining a leadership position. The data used are panel data of a cohort obtained during the cohort's middle and high school years. In OLS estimation, this paper finds positive height effects for boys. However, when controlling for individual fixed effects, the estimate is not statistically significant. For girls, the height effects are found on neither OLS nor FE model.

We find that there is the height premium in the Korean labor market. The wage increases by 1.5% with a centimeter increase of height among male workers of ages 30-49. This estimate is barely affected by family backgrounds such as a worker's father's education or occupation. It is rejected that a worker's height is a proxy variable for his health, which increases his wage. The height premium is unrelated with obesity. It is not also supported that a worker's height affects his wage through his occupational choice. We partly confirm that a worker's height affects his wage through his educational choice. The estimated height premium of 30's in Korea is comparable to that of age 33 in Great Britain.

Satellite application services can be divided into realtime services like voice communications and non-real time services like traditional data communications. To support both types of services on the same On-Board Switching(OBS), a scheduler which depends on their service classes is required. A fixed priority scheduling policy has a starvation problem. In this paper we propose a scheduling scheme based on premium and age. Premium is a fixed value which is given to a certain class of services. Age is another parameter of the scheduling policy and it will be increased by one for every scheduling cycle. The scheme we propose chooses a packet which has the largest sum of its age and premium. Simulation results indicate that the proposed approach shows better performance in both average cell delay and std-dev of cell delay for the lower class of service. There is no staying in infinite starvation state.

This study examined the effects of insurance company's CSR activities on customer-based brand assets and customers' intention to pay premium prices in order to identify the possibility of CSR activities as an insurance company's differentiated marketing strategies. Throughout collecting 510 surveys, this study has proved that economic and charitable activities had a effect on customer-based brand assets, also economic and environmental activities had a effect on intention to pay premium prices. In addition, the mediating role of the customer-based brand asset between economic and charitable activities and intention to pay premiums was proved. Lastly, it was confirmed that the level of SNS usage moderates the relationship between economic activities and customer-based brand assets. Based on the results, this study provides insurance companies with an effective marketing strategy of the CSR program.

This paper examines the relationship between information risk and equity premium in the Korean stock market. We use accruals quality as a proxy of information risk. Accruals quality (AQ) is estimated by Dechow and Dichev (2002) model, and then AQfactor is constructed based on the estimated AQ. Time-series and cross-sectional regression models are used to examine the relationship between information risk and equity premium, reflecting the critics of Core et al. (2008). The result of the paper shows that information risk proxied by accruals quality is not priced in equity premium in the Korean stock market. This result is consistent with Core et al. (2008) for US firms, but different with Francis et al. (2005) for US firms and Gray et al. (2008) for Australia firms. Also, the result shows that AQfactor is closely correlated with firm characteristic variables such as firm size. This implies that the effect of AQ on equity premium is more likely to arise from the pricing error due to firm characteristics rather than from an unknown risk factor.

인터넷 서비스 수요의 급증으로 IP망의 대용량화와 고품질 서비스 제공에 대한 요구가 증대되고 있다. 이에 대해 네트워크 시설의 확충이나 트래픽 엔지니어링의 적용을 통해 대응해 왔으나, 멀티미디어 서비스 증가, 데이터 유형별 QoS 특성의 차이로 인해 기존에 적용해 오던 망 관리 시스템에의 의존에서 탈피, 현재 나타나고 있는 통신서비스 활동 특성의 변화를 감안, 실제 사용자의 서비스 이용 차원에서 고품질, 광대역 서비스를 제공해 줄 수 있는 관리 방안에 대한 모색이 필요하게 되었다. 이에따라, Intserv, Diffserv, RSVP, MPLS 등이 등장하였고, QoS 보증(SLA)에서는 서비스품질 보장 범위의 확대를 비롯한 다양한 고객요구가 증가하고 있는 상황이다. 이에 본 논문에서는 통신서비스 전반에 나타나고 있는 차별화된 프리미엄 서비스의 등장에 따른 QoS 보증방안에 대해서 다루고자 한다. 이를 위해, 우선 통신사업자의 네트워크 운용환경 변화방향에 대해 점검해 보고, 프리미엄 서비스의 도입이 가능한 대상과 범위에 대해서도 살펴본다. 이어서, 새로운 서비스 환경에서의 사업 기회와 진략 수립 방향, 법${\cdot}$제도적인 측면을 포함한 사업환경에 대한 시사점을 제공하고자 한다.

본 사례는 국내 최대 화장품 기업인 아모레 퍼시픽의 프리미엄 한방화장품인 설화수 브랜드의 탄생과 발전과정을 소재로 하고 있으며, 설화수의 브랜드 정체성 확립 전략과 글로벌 전략에 대해 다루고 있다. 설화수는 아모레 퍼시픽의 오랜 생약 화장품 연구의 결과로 탄생한 제품으로 현재 한방 화장품시장의 60%를 차지하고 있는 시장지배자일뿐 아니라 아모레 퍼시픽이 강력한 외국 기업들을 제치고 1위의 프리미엄 화장품 공급자로 등극하게 한 일등 공신이다. 설화수 브랜드는 시의 적절한 제품 컨셉과 탁월한 브랜드 정체성 확립으로 오늘과 같은 위치에 이를 수 있었으며, 문화 마케팅이라는 설화수의 브랜드 정체성과 잘 조화된 전략을 통해 후발 경쟁자들과의 간격을 더욱 크게 벌려 놓았다. 국내의 경쟁과 성공에 안주하지 않고, 글로벌 전략을 선택한 아모레 퍼시픽은 아시아 권을 중심으로 세계시장에서 괄목할 만한 성장을 이루었으며, 더 나아가 설화수는 아모레 퍼시픽의 프리미엄 브랜드로의 포부를 담고 2004년 홍콩에 진출한다. 잘 준비된 브랜드 구축 계획과 4P 전략으로 초기 안정된 시장안착을 달성하고 빠르게 성장하고 있는 설화수이지만, 국내와는 다른 낮은 경쟁기반과 국내에서 성공한 전략의 실행여부 등 새로운 도약을 위한 고민이 계속되고 있다.

This study analyzes the determinants of wage premium, defined as the excess of actual wage rate over opportunity wage, for the average worker in a Korean bargaining unit. Average wage premium of a firm is decomposed into quasi-rent per worker and rent-sharing rule. Per capita quasi-rent, representing a firm's ability to pay, is defined as the difference between sales revenue and the opportunity cost of mobile factors, divided by the number of employees. Rent-sharing rule, a measure of workers' bargaining power, is defined as the average wage premium divided by the per capita quasi-rent. Empirical results show that the differences in wage premium among Korean bargaining units are much better explained by the differences in quasi-rent than by the differences in bargaining power. Also, comparing the results of 1986 with those of 1988 show that the wage settlement mechanism in 1988 was not quite different from that of 1986, in spite of the drastic change in industrial relation system in 1987. It may simply yield higher opportunity wages, by raising the bargaining power of overall workers. The tendency of Korean labor market in 1988 to show a dual structure of high & low wage premium sectors, is not due to the fact that the differences in bargaing powers across firms tend to expand, but to the fact that unions tend to reduce the wage differences among the workers within an enterprise by pursuing more equal distribution of total wage premium. Hence, the policies for reducing the wage differentials across firms should focus on rent-regulating industrial policies, e.g. eliminating monopoly rents by deregulation.
