Purpose This study empirically investigates the impact of information technology(IT) investments on the financial and non-financial performance of a manufacturing firm. We examined the interaction effects of IT investments and strategic applications levels of information systems(IS). This study also demonstrated the three-way interaction effects of IT investments, levels of IS strategic applications, and perceived environmental uncertainty(PEU). Design/methodology/approach For this study, empirical data were collected from 98 manufacturing firms with the structured questionnaires. The data were analyzed with multiple regression models, and partial derivatives were utilized to identify the directions of the impact. Findings From the empirical results, it was found that when both the levels of IS strategic applications and the degrees of IT investments are high, the ratios of the costs of goods sold to total sales(RCGS) and the labor costs to total sales(RLCS) are decreased, as it were, the performance of a firm is improved. However, it was observed that when the levels of strategic IS are low, the high degrees of IT investments do not contribute to the improvement of a performance. The results showed that when the levels of strategic IS are high, the high degrees of IT investments incur the high RSAE not low RSAE. When PEU is considered, the empirical results showed that under the low degrees of PEU, the IT investments under high levels of strategic IS applications (strategic IT investments) improve the performance, as it were, low RCGS, and high degrees of perceived financial and non-financial performance. However, under high PEU, it was observed that high degrees of strategic IT investments do not increase the performance. When PEU is high, the strategic IT investments reduce RSAE, and under low PEU, RSAE is increased.

환경원가를 환경투자와 비용으로 구분하여 이 두 요소를 유발하는 요인과 효과를 실증 분석하였다. 결과를 보면 수익성(ROS 등)은 환경관련투자 및 환경보전비용에 유의적인 영향을 미치지 않았으며 레버리지 비율은 환경투자활동에 음의 영향을 미쳤으며 R&D 비율도 악영향을 나타내었다. 한편 지배주주의 비중이 높을수록 단기적인 환경보전비용의 지출은 물론 환경시설투자 등에도 능동적으로 대처하였다. 그리고 환경관련투자와 환경비용을 통한 노력이 재무성과(ROS)에는 부정적으로, $CO_2$ 배출량의 감소와 같은 환경성과에는 긍정적으로 나타났으며 결과적으로 환경경제효율에는 긍정적 방향을 나타냈으나 유의적이지는 않았다. 이것은 환경관련지출이 $CO_2$ 배출량 감소와 같은 긍정적 효과를 초래하지만 재무성과가가 악화된 것만큼 $CO_2$ 배출량 감소효과가 따라가지 못한다는 사실을 의미한다.

선진국 대기업간 인수 ·합병, 개도국 공기업 민영화와 구조조정 등으로 인하여 세계경제에서 외국인직접투자가 차지하는 비중은 커지고 있다. 각국별 외국인직접투자 결정요인을 비교 ·분석함으로써 외국인직접투자 유치를 위해서 중점적으로 추진해야할 분야가 국가별로 다르다는 것을 강조하였다. 아울러 차관, 포트폴리오투자 등 타 자본시장 개방은 외국인직접투자 유치에 직접적 효과가 없었다. .

This study examined factors associated with the ownership of stock investments and the amount of stock investments of households using the 2001 National Survey of Family Income and Expenditure by National Statistical Office. Households with large amounts of income, savings, and liabilities were more likely to invest in stocks and have large amounts of stock investments. Also, households with young and male householders, highly educated householders, a number of children in school, and housing ownership were more likely to invest in stocks and have large amounts of stock investments. On the other hand, self employed households and dual income households were less likely to invest in stocks and have small amounts of stock investments.

The purpose of this study is to analyze the effect of the R&D subsidies by the government on the private firms' R&D investments in the Korean pharmaceutical industry, which are supposed to have positive effects on their economic performance. We also estimate the relationship between the private firms' R&D investments and firms' economic outcome. Empirical analysis is done by Error Component 2 Stage Least Squares(EC2SLS) estimation using 43 pharmaceutical firms' 8 years' panel data. The elasticity of the government R&D subsidies on the private R&D investments is 0.021%, which we cannot say 'efficient'. Also R&D investments have positive effects on the economic outcome of the pharmaceutical firms, as we expected. We propose several suggestions in the conclusion for the efficient way of government R&D subsidies to induce more private R&D investments.

There has been investments by firms to protect workers' health and to improve their health status. Most of the investments are made on the ground of legal requirement. However many argue that the amount of investments made falls short of the legally required level. One of the reasons why firms are not active in undertaking required investments is that they are not certain whether such investment is economically beneficial to them or not. Using CBA (Cost-Benefit Analysis), this study investigates whether firms' investments on workers' health are economically justifiable or not. All kinds of expected costs and benefits are itemized and calculated, and costs are compared with benefits. The result shows that if firms fully undertake the legally required investments, total expected costs amount to W453.2 billion and expected benefits accruing to reductions from medical care costs, workers compensation costs, litigation costs in case of legal suit, work days lost, and etc. comes up to W2,086.8 billion. In other words, economic benefits from firms' investment on industrial health far outweighs their costs. As the economy grows, the probability of having various occupational disease increases. It is well conceivable from this study outcome that, the higher the probability, the greater the social loss would be, and the greater the benefits from proper investments on workers' health.

An analysis of the railroad industry for R&D investments has been insufficient whereas there are lots of analysis of accumulation of technology, economic performances and ripple effects for macroscopic view and other industry of R&D investments. This study decided intellectual rights, patent, and paper as common indicators of scientific and technological performances for setting up performance targets through surveying and analysis of preceding study and verified a appropriateness of scientific and technological performances for railroad R&D 11 projects which were successfully finished. Preceding study has been set up performance targets by research investments as input, but this study made a performance target by model through a cross-sectional and residual analysis of performances of railroad R&D 11 Projects in applying research investments, capital investments, inner labor cost and inner labor cost per man and research time as inputs, and verified a validity and a empirical analysis through analysis of other project.

The purpose of this study is to examine negative IT performances produced by irrational fashion-mimic IT investments in firms. Since most studies have been carried out on the assumption of rational investment decisions, many of them have revealed positive investment process and performances in firms. However, fashion-mimic investments to follow the paths of market leaders rather than rational investment decisions have been of frequent occurrence in many firms. This study divided types of mimic investments into subgroups where one subgroup has fashion-mimic properties and the other subgroup retains rational-mimic properties. We compared differences in performance of these subgroups to investigate effects of irrational investments in IT projects. The results indicated that there are differences in performance between fashion-mimic and rational-mimic investments. Additional analysis also revealed differences in performance at the presence of CEO control in the case of fashion-mimic investment subgroup.

As the life expectancy increases resulting in the aged society, the post-retirement life became one of the most important concerns of people. The long-term investment vehicles such as retirement savings and pension plans have been introduced to meet such demand of society. This paper examines the impact of asset allocation strategies on the long-term investment performance. Because of the unusually long investment horizon and the compounding effect, a suboptimal asset mix in a retirement plan can be a very costly and irreversible mistake. Instead of relying on anecdotal evidence to evaluate the merits of different allocation strategies, this paper performs various tests including stochastic dominance tests using both actual data and Monte Carlo simulated data that best fit the historical experience. The results indicate 1) the long-term investments perform better than the short-term investments, 2) the optimal asset allocation strategy for the long-term investments should be highly equity dominated.
