Recent discussions about a minimum wage increase (MWI) and its influence on the economy have mainly focused on the quantitative aspects, such as labor costs and employment. However, concerning the qualitative aspects, an MWI could have positive effects by enhancing firm productivity and crowding out marginal firms from the market. These positive effects of an MWI can offset, to some extent, its potential negative effects - increasing labor costs and decreasing employment, among others. In this regard we empirically examine the impact of an MWI on firm productivity (total factor productivity). Using firm level panel data from the manufacturing industry in Korea, we calculate the influence rates of a minimum wage by sector and by firm size (number of workers), and analyze its effects on firm productivity. In particular, the production functions of the firms are estimated by taking into account endogeneity among the input factors, in order to resolve the drawbacks of existing studies - underestimating the capital factor coefficient and overestimating the labor factor coefficient. This study finds that the influences of an MWI on wages, employment, and productivity are substantially different across sectors and firm sizes. While an MWI has shown to have positive influences on productivity growth in the manufacturing industry as a whole, each sector demonstrates a different direction of effect, and the degree of productivity change also varies by sector. The impacts of an MWI on firm productivity are generally estimated to be more negative for smaller firms, but in some sectors the effects are found to be positive. In addition, the wage increases resulting from an MWI seem to cause a productivity enhancement across all sectors in the manufacturing industry. The policy implications of this study are as follows. Considering the empirical findings that an MWI causes an increase in productivity in many sectors of the manufacturing industry, it would be desirable to take into consideration not only the negative side effects but also the positive effects of an MWI when designing any future minimum wage policy. Moreover, in spite of there being a uniform minimum wage, this study finds that the diverse influence rates of a minimum wage across firms have different impacts on wages, employment, and productivity across sectors or firm size. This finding could be conducive to discussions about differentiation among minimum wage schemes by sector or firm size.

Korean card firms suffered harsh setbacks due to high credit defaults in 2002 and 2003, after issuing cards recklessly. Their key principle is changed to grow without damaging profitability and financial soundness. However, competition in the credit card market is heating up rapidly. Bank-affiliated card firms, having stronger sales networks and more capital than independent issuers, have increased their investments in card affiliates in a bid to develop new cash cows. Moreover, newly emerging independent card firms have waged fiercer campaigns to raise their credit card market share. In order to overcome these business conditions, S-card has settled on a strategy that focuses on stepping up marketing aimed at increasing charge card spending rather than credit card loans or cash lending services. Accordingly, S-card reformed the current business classification system of merchants, which was out-of-dated and originally built for the purpose of deciding merchant service fees only. They also drove customer segmentation planning to deliver the right customers to the right merchants. In this paper, we emphasize the problems of business classification systems of merchants with which most credit card firms have faced, and the need for reforming them not only to provide customer-tailored services but also to raise their business promotion excellence by reviewing S-card's process of customer segmentation.

This study examines the determinants of proportion of self-employed and their policy implications focusing hotel/restaurant and wholesale/retail sectors in Korea. In this study, we estimate the optimal size of self-employed in Korea using OECD data. Several hypothesis are tested by use of the regression analysis on the panel data of OECD economies during 2000-2007 period. Using the panel data of per capita GNI, unemployment level, income tax burden, we found that the excess supply level of self-employed was about 8.0%~9.5% overall. We also found that the excess supply level of self-employed was 13.7~14.1% for hotel and restaurant sector, and 10.4~11.1% for wholesale and retail sector. This results imply that strategically coordinated programs for noncompetitive sectors are more effectively implemented. Furthermore, more aggressive entry and exit policies are needed to solve the over-supply problem of self-employed in Korea.

The number of domestic construction company is expanding every year while the construction workers' exposure to disaster risk is increasing due to technological advancements and popularity of high-rise buildings. In particular, the industry faces greater fatalities and severe large scale accidents because of construction industry characteristics including influx of foreign workers with different language and culture, large number of aged workers, outsourcing, high place work, heavy machine construction. The construction industry is labor-intensive, which is to be completed under given timeline and consists of unique working environment with a lot of night shifts. In addition, when a fixed construction budget is not secured, there is less investment in safety management resulting in poor risk management at the construction site. Taking account that the construction industry has higher accident risk rate and fatality rate, risky and unique working environment, and various labor pool from foreign to aged workers, preemptive safety management through risk factor identification is a mandatory requirement for the construction industry and site. The study analyzes about 8,500 cases of construction accidents that occurred over the past 10 years and identified risk factor by construction industry sector to secure a systematic insight for risk management. Based on interrelation analysis between accident types, work types, original cause materials and assailing materials, there is correlation between each analysis factor and work industry. Especially for work types, there is great correlation between work tasks and industry type. For reinforced concrete and earthwork are among the most frequent types of accidents, and they are not only high in frequency of accidents, but also have a high risk in categories of occurrence.

데이터마이닝 기술은 1990년대 전반에 걸쳐 기초연구가 본격화돼 최근 2~3년간 부쩍 산업계에서 실용화되기 시작했다. 필자가 조사한 범위에서는 금융이나 유통 등의 분야에서 마케팅 조사를 하는데 적용하는 것이 주류였으며, 기타 제조업이나 통신 서비스 업종에서도 품질관리 및 고객관리 등에 적용시키고 있다. 이처럼 데이터마이닝 기술이 급속한 보급을 보이고 있는 배경에는 데이터가 점차 디지털화 되어 가고 데이터베이스 축적에 의해 그 대상이 되는 데이터를 풍부하게 얻을 수 있게 되었다는 점이다.

뜻한 바는 달라도 각자가 목표한 바를 이루기 위해서 경쟁자와의‘전략적 제휴’를 맺어야 할 때도 있다. 앞서는 기술력과 패기로 똘똘 뭉쳤다 해도 네트워크와 자금 등 기반 여건이 열세인 벤처기업들에게 무엇보다 필요한 것은 더불어‘공생하는 것’이다. 단순한 경쟁관계를 넘어 이제는 업종간의 전략적 파트너십으로 서로간의 이점을 나누는‘협력의 공유폴더’를 생성해보자.

국내 이동통신사업자들은 자사 고객의 충성도를 높이기 위해 사용요금의 일정비율에 해당하는 포인트와 제휴사의 서비스를 제공하는 멤버십 제도를 운영하고 있다. 최근 포인트에 대한 소비자의 권리의식이 높아지면서 통신사업자들 뿐만 아니라 포인트를 발행하는 타 업종에서도 사회적 이슈로 제기되고 있다. 이에 본고에서는 이동통신사가 운영하는 멤버십 제도의 운영 실태를 살펴보고 이용자를 보호할 수 있는 방안들을 검토해 보고자 한다.
