For integrating and utilizing the statistical data, which is summarized by arbitrary areal unit such as demographics, with stellite imagery or other GIS data, areal unit of both data should be accorded. Dasymetric mapping is proposed as a useful method fur disaggregating the aggregated statistical data to finer areal unit or generating surface model from object data such as polygonal area. This research evaluate the effectiveness of dasymetric mapping by 1) summarizing the yellow page information by administrative district, 2) modeling the business density using dasymetric mapping, and 3) comparing the business densities of raw data and that of spatial interpolation result.

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.

2007년 4월 1일 체결된 한미 FTA 협약으로 법률시장의 개방 또한 불가피해진 상황이다. 협정 발효 후 5년 내에는 완전 개방이 이루어져 미국 로펌과 국내 로펌 간 동업사업체 설립이 허용된 상태이다. 이러한 시점에서 로스쿨법이 지난 7월 국회 본회의를 통과하였다. 로스쿨법의 시행을 앞두고 우리 법률시장의 현황 및 특징을 알아보고, 법률시장개방에 따른 대응책을 검토해 봄으로써 로스쿨이 성공적으로 정착하기 위해서는 어떤 요건들을 갖추어야 하는지 살펴보기로 하자.

The aim of this study is to consider the degree of supply-demand balance in relation to the characteristics of retail sale activities in depopulation aging regions and the degree of aging by using simple regression analysis. The major findings of this study are as follows. While aging society, and aged society regions show a similar major retail sale industries, super-aged society shows fewer major industries and different industry composition. These characteristics are seen by different phenomenon and the background of the particular retail structure. The first one is that the number of employees per establishment increases when the aging phenomenon is not accelerated, and the annual sales per capita purchasing power decrease because their purchasing power becomes lower when the aging phenomenon is severe, but it also shows a high density of establishments because disperse location of establishment within depopulation aging region. The second one is the retail structure with high labor productivity in a aged and superaged society region. We identify the extent of demand and supply in general retails, fuel retails, food and beverage, and tobacco retails which represent the highest sales rates in depopulation aging region. As a result, general retails are seen as 'supply-demand balance region' in aged and super-aged society, fuel retail sales in aged and super-aged society which generally shows less sales, and food and beverages, and tobacco retails in super-aged society. The higher the degree of aging is, the less the regional differences in the gap between demand and supply is. This is because the difference in purchasing power between these regions is small.

Using a panel data set covering 19 Korean manufacturing sectors for the period 2009-2015, this paper investigates the extent to which industry characteristics affect the mode of entering foreign markets. The estimation results across various specifications show that firms prefer affiliate sales to export as firm heterogeneity increases, implying positive effects of productivity regarding foreign relative to domestic operations. The motive for overseas production is reinforced as economies of scale at the plant level decrease and economies of scale at the corporate level increase.

IMF 이후 기업들은 구조조정을 통한 체질개선에 총력을 기울임과 동시에 그 동안의 외형적 성장에서 탈피하여 투자 자본의 효율 향상을 위해 기업가치를 극대화하려고 노력하고 있다. 따라서. 각 사업체의 중점 육성 부분과 매각 부분을 선별하게 되었으며, 이해 사 간의 인수 합병이 빈번히 일어나고 있다. 그러나, 이렇게 생성된 기업체의 경우, 기존 전산 시스템의 하드웨어, 소프트웨어, 데이터베이스 등의 불일치로 통합에 많은 시간과 비용이 발생하고 있다. 따라서, 본 논문에서는 기존 전산 시스템의 플랫폼 불일치를 극복하며, 기존 시스템으로부터 개발되는 새로운 시스템으로의 전이를 자연스럽게 해줄 플랫폼 독립적인 대용량 데이터 동기화 서버(SyncDB2DB)를 설계한다.

This paper tests whether or not manufacturing specialization, employment growth, establishment size, employment size, industrial mix in manufacturing, regional difference between the Capital region and the others and so on are empirically related to manufacturing employment volatility levels across 203 municipalities called shi-gun-gu during the period 1990~2006. Using the spatial econometric analysis of cross sectional data, the municipalities tending to be more volatile are more specialized; they have higher-than-average employment growth rates, smaller establishment and employment sizes, regardless of any industrial mix in manufacturing; and they tend to be located in the Capital region. Unlike existing foreign literature based upon the spatial econometric analysis of cross sectional data, this paper finds that volatility of growth in a municipality is negatively rather than positively influenced by volatility of growth in its neighboring municipalities.

We investigate wage differentials in Korea in the manufacturing industry, as well as factors affecting structural change in wage determination for the pre- and post-financial crisis regimes. We use the 1995 and 1999 data from the Survey Report on the Wage Structure (SRWS) from the Ministry of Labor. Principal components regression analysis is used to tackle multicollinearity. We employ factor analysis to reduce a set of variables to a smaller number, which contain observed and latent variables. Our empirical investigation provide evidences for changes in wages structure between 1995 and 1999. In 1995, the job quality factor is the most critical in the determination of wages, while in 1999, the industry attributes factor impacts greatly on the wages.

This paper examines the effect of trade liberalization or globalization, more broadly, on plants' growth as well as on "bi-polarization". To do so, we reviewed the possible theoretical mechanisms put forward by recent heterogeneous firm trade theories, and provided available micro-evidence from existing empirical studies on Korean manufacturing sector. Above all, the empirical evidence provided in this paper strongly suggests that globalization promoted growth of Korean manufacturing plants. Specifically, evidence suggests that exporting not only increases within-plant productivity but also promotes introduction of new products and dropping of old products. However, the empirical evidence also suggest that globalization has some downsides: widening productivity differences across plants and rising wage inequality between skilled and unskilled workers. Specifically, trade liberalization widens the initial productivity differences among plants through learning from export market participation as well as through interactions between exporting and R&D, both of which increase plants' productivity. We also show that there is only a small group of large and productive "superstar" plants engaged in both R&D and exporting activity, which can fully utilize the potential benefits from globalization. Finally, we also show evidence that trade liberalization interacts with innovation to increase the skilled-unskilled wage inequality.
