This study examines the effecs of National Pension Service blockholders on accounting conservatism. The sample consists of 10,117 non-banking firm-years listed in Korea Stock Exchange(KOSPI) during the period 2011 to 2018. The results of this study are as follows. First, it was found that companies in which the National Pension Service as a major shareholder hold more than 5% of the shares are less prone to conservative accounting treatment than those that do not. Second, such a negative relationship between investment by the National Pension Service and conservative accounting was consistently found even when the investment period of the National Pension Service was divided into short-term (less than 1 year) and long-term (more than 3 years). It is expected that the National Pension Service, the largest institutional investor in Korea, will be able to carry out meaningful management control activities on investment companies. As the monitoring function of the National Pension Service works effectively in the capital market, agency costs are reduced, and investors' demands for corporate conservative accounting have decreased.

본 연구는 우리나라 IPO시장에서 나타나고 있는 초과수익률의 원인을 밝히고자 최근 벤처금융의 중심으로 급부상하고 있는 KOSDAQ시장의 공모 IPO를 대상으로 실증분석을 시도하였다. 연구결과 상장일 표본전체 IPO의 초과수익률(AR1)이 9.91%로 나타났으며, 벤처캐피탈투자 IPO는 5.13%, 비투자 IPO는 13.29%로 나타났다. 상한가의 행진이 종료된 날을 기준으로 한 표본전체 IPO의 초과수익률(AR2)은 30.97%, 벤처캐피탈 투자기업 IPO는 24.34%, 비투자기업 IPO는 34.67%로 나타났다. 초과수익률의 원인을 분석하기 위한 8개의 변수 중 IPO의 수요증감 척도인 KOSDAQ 지수는 초과수익률(AR)과는 양(+)의 관계로, 벤처캐피탈리스트들의 능력 및 가치책정의 행태를 엿볼 수 있는 변수인 본질가치와 공모가액의 차이는 음(-)의 관계로, 사업규모나 자본조달의 크기를 엿볼 수 있는 공모금액의 크기는 양(+)의 관계로 1% 유의수준에서 유의한 것으로 나타났다. 그러나 여타 변수들은 통계적으로 유의성을 확보하지는 못하였으나 초과수익률의 원인이론으로 '신호이론'과 '투기적 거품가설'에 의한 설명이 가능하였으며 분석결과를 다음과 같이 정리할 수 있었다. 첫째, IPO 본질가치에 대한 신뢰와 IPO의 발행규모에 대한 신뢰수준이 통계적으로 유의한 결과로 나타났는바 이러한 결과는 기업가치와 벤처 또는 사업의 계속적 수행 등에 대한 신호역할을 수행하고 있다고 할 수 있으며 상장초기 초과수익률은 주로 이러한 신호역할에 의한 수요집중으로 발생된 결과인 것으로 사료되었다. 둘째, 노련한 벤처캐피탈회사로 선정된 KTB의 투자기업들은 상장 후 4주간의 거래에 있어 AR 평균이 음(-)으로 여타 벤처캐피탈이 투자된 기업보다 손실 폭이 더욱 켰음에도 불구하고 상장일 초과수익률 AR2가 매우 높게 나타나 우리나라 IPO시장에 있어 과민반응(fads) 현상이 존재하고 있는 것으로 분석되었다. 셋째, 벤처캐피탈 투자 IPO의 초과수익률이 상대적으로 낮아 벤처캐피탈 투자여부가 IPO의 저가발행 수준을 축소하고 있어 벤처캐피탈리스트의 제 3자 보증역할이 어느 정도는 수행되고 있는 것으로 분석되었다.

The Purpose of this study is to investigate the problems arising during the investment decision making on maintaining and improving Manufaturing information systems. The detailed problem considered in this study is to determine the priorities of various investment alternatives on improving Manufacturing systems. For this purpose, this study suggests a systematic procedure in which the analytic hierachy process is used to fix the important weights of alternatives, together with a normalization step, and then an integer programming model to select the optimal set of alternatives that maximize the total priority while satisfying the allowable budget and the time limitation.

International trade flows have been determined by social, cultural and political environment around the world as well as economic elements. The environment of international trade has changed rapidly as the world has globalized. Significant changes have been generated in the international trade flows. This study investigates the influences of economic globalization on the international trade flows. The changes in international trade flows examined comprehensively by integrating trade with industrial locations, investment, and the various trade related environments. The focus laid on the integration of world economies, such as widening and intensifying international linkages in economic, political and social relation. Special concerns are laid on the impacts of Foreign Direct Investments (FDI) by Trans National Corporations (TNCs), which affect the supply-demand distributions of commodities by industrial relocations, and the expansion of intra-firm trade flows on the international trade flow patterns. The geographical characteristics of tile origins and destinations of FDI flows analyzed, since the spatial patterns of the intra-firm trade flows are determined by them. The FDI and intra-firm trade flow patterns have changed significantly over time.

This paper seeks to explore the effects of the board structure and director characteristics on the R&D investment of a company. The results from analyzing 95 Korean listed companies reveal that the directors' demographic characteristics substantially affect the R&D intensity. When the directors are younger, major in science or engineering, and have an experience of studying abroad, they tend to be supportive of R&D, thereby increasing the R&D expenditure. Particularly, the effects of insider directors are shown to be greater than those of outside directors, which implies that the Korean corporate boards are mainly operated by insiders. Furthermore, when the relative power of boards is greater than the management, the effects of inside directors, rather than overall directors, on R&D intensity are weakened.

For the application of the diffusion equation, slope height and maximum slope angle are calculated from the plotted slope profile. Using denudation rate as a solution for the diffusion equation, an apparent age index can be calculated, which is the total amount of denudation through total time. Plots of slope angle versus slope height and apparent age index versus slope height are useful for determining relative or absolute ages and denudation rates. Mathematical simulation plots of slope angle versus slope height can generate equal denudation-rate lines for a given age. Mathematical simulations of slope angle versus age for a given slope height, for equal denudation-rate at a particular profile site, and for comparing to other sites having controlled ages.

This research confirms a non-linear relationship between R&D investment and performance of small and medium-sized enterprises and measures the adequate level as threshold value. Although previous studies did not consider the time lag and estimated indirectly the level using the R&D investment squared term, this study assumes 2 years time lag and uses the threshold estimation model to measure directly. We find that there is the S-curve relationship between the profit rate as R&D output and R&D intensity and the ratio of researchers to employees as R&D input. Also, we estimate the adequate levels of R&D investment, 6.4% for R&D intensity and 13% for the ratio of researchers to employees. This relationship and measurement of the level can offer basic facts and implications about R&D policy and strategy.

This paper examined the strategic inward foreign direct investment and business performance in free economic zone. attractive of segment and country's competitive advantage were as proxy for the matrix of appropriateness. The marketing differentiation, inducement promotion, incentive, and business support were as proxy for the business performance. Based on the analysis of one hundred twenty cases, the following results were found. First, based on the attractive of segment and country's competitive advantage, the types of four segments was drawn. Second, the segment 4 have a significantly difference on their business performance. Third, strategic foreign direct investment have a significantly high difference on their marketing differentiation but a significantly low difference on their business support. Finally, the business performance, in order of performance, have a significantly difference on their marketing differentiation, inducement promotion, incentive, and business support. Limitation and suggestions for further are also highlighted.
