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.

This study expands the current body of research by exploring multiple scenarios of insufficient and excessive IT security investments caused by interdependent risks and the interplay between IT security investments and cyber insurance. A key finding is that organizations experiencing interdependent risks with different types of cyber attacks (i.e., targeted and untargeted attacks) use different strategies in making IT security investment decisions and in purchasing cyber insurance policies for their information security risk management than firms that are facing independent risks. The study further provides an economic rationale for employing insurance mechanisms as a risk management solution for information security.

This article explores economic models that show the optimal level of information security investment in the presence of interdependent security risks, Using particular functional forms, the analysis shows that the relationship between the levels of security vulnerability and the levels of optimal security investments is affected by externalities caused by agents' correlated security risks. This article further illustrates that, compared to security investments in the situation of independent security risks, in order to maximize the expected benefits from security investments, an agent should invest a larger fraction of the expected loss from a security breach in the case of negative externalities, while an agent should spend a smaller fraction of the expected loss in the case of negative externalities.

Intangible Assets are more important determinants of firm value than others in a digital information-based economy(Lev, 2001). Prior research reveals that investments in intangible assets such as R&D and advertising expenditures are associated with firm value. This paper examines the effects of the corporate investments in the information technologies(IT) on stock return and economic goodwill. The sample consists of 152 firms listed on the Korean stock market in 2002. To test hypothesis We employed multiple regression models. Results are as follows; First, IT environment, IT process, and IT human resource are positively associated with firm's IT value. Second, firm's IT value is positively correlated with firm's economic goodwill. Third, firm's IT value is positively correlated with firm's stock return. These results suggest that the investments related with IT are effective in cultivating firm's value and Stock investors can make the best use of firm's announcements related with IT value. Thus the authorities concerned need to expand the public announcements related IT value.

Many organizations have spent huge investments on information systems (IS) but are unable to achieve the maximum benefits expected. The problem of system underutilization of implemented IS is a major factor that causes the lackluster returns on organizational investments in IS. In light of the need for solutions to underutilization, researchers are beginning to explore IS infusion to enhance task performance. IS infusion is the extent to which an individual fully uses the system to enhance his or her task performance. So far, there has yet to be any significant finding or theory to explain the phenomenon. Therefore this study offers a conceptual framework on IS infusion based on the socio-technical system perspective. Particularly, this study investigates the influence of job fit, task competence, technology competence, self-determination with technology and self-determination with task on IS infusion. The analysis following the collection of empirical data found that job fit and self-determination with technology are positively related to IS infusion. This study serves as a basis for future research and suggests important implication to managers and system designers in promoting IS infusion.

본 연구에서는 1998년부터 2008년까지 우리나라 거래소에 상장되어 있는 기업들을 대상으로 기업의 내적인 투자기회, 외부금융의존도 및 타인자본비용이 기업의 자본투자의사결정에 미치는 영향을 분석하였다. 기업의 투자의사결정은 거시적인 경제정책에서도 영향을 받지만 기업 자체가 처한 상황인 영업경쟁력, 자본시장 이용조건, 자본비용 등의 요인에 의해서도 영향을 받다. 본 연구에서는 선행연구에서 초점이 되었던 법인세율이 기업의 자본투자에 미치는 영향을 통제한 상태에서 기업의 투자결정요인을 기업적 측면에서 분석하였다. 분석결과는 다음과 같다. 첫째, 기업의 투자기회는 자본투자에 양(+)의 영향을 미치는 것으로 나타나 기업의 영업 경쟁력인 투자기회가 많을수록 기업의 투자는 촉진되는 것으로 나타났다. 그러나 이러한 영향은 외부금융의존도가 높을수록 약화되며, 투자기회가 자본투자에 미치는 영향이 타인자본비용이 높을수록 약화되는 것으로 나타났다. 둘째, 기업의 외부금융의존도와 자본투자는 양(+)의 상관관계가 있는 것으로 나타나 외부금융의존도가 높은 기업의 경영자들이 자본투자에 적극적임을 암시한다. 그러나 타인자본비용이 높아질수록 투자기회가 자본투자에 미치는 영향의 정도는 낮아져 투자기회가 많다고 할지라도 타인자본비용이 높은 경우에는 자본투자에 저해요소가 됨을 암시한다. 셋째, 기업의 타인자본비용이 높을수록 자본투자는 낮아지는 것으로 나타났으며, 유가증권 시장 표본의 경우 투자기회가 자본투자에 미치는 영향은 타인자본비용이 높을수록 작아지는 것으로 나타났다. 본 연구에서는 기업의 내적인 요소가 자본투자에 미치는 영향을 분석하였다는 점에서 의의가 있으며, 향후에는 자본투자에 영향을 미치는 다양한 요인들을 밝혀내려는 시도가 필요할 것으로 보인다.

Lots of investment projects of new development and redevelopment for information systems have been not taken care of in the field of administration and evaluation, for these information systems projects have unique characteristics such as technology sensitiveness, network effectiveness, embeddedness, and externality. In fact, quantitative and qualitative evaluation of investments in information systems projects are not sufficient. It is critically important to generally evaluate benefits of development or operation cost, urgency, external effects, and so on. In addition, the efficient monitoring and effective analysis of information systems are surely needed for beneficient results of investment in information systems. We propose an economics evaluation model for information systems projects.

Despite the large and ongoing investments in information systems and technologies, many organizations still suffer from the lack of integration and interoperability of multiple information systems, In order to deal with these enduring problems, a number of government organizations and corporate firms in the United States have developed and maintained IT architectures through enterprise architecture planning. An IT architecture is a decision-making framework for IT planners and developers, establishing guidelines for the individual IT resource owners and users. It provides guidance to those involved in building and maintaining IT systems and infrastructure. Enterprise architecture planning represents a new paradigm of information systems planning in that it addresses the long-term view of the enterprise organization from top-level principles to detailed technology architectures. This paper explores a couple of cases in the successful implementation of IT architectures in both public and private sectors, and proposes a step-by-step methodology for building an effective IT architecture.

This research proposes a conceptual framework to highlight the importance of change management after firms implement ERP systems. With ERP, firms need to rework their business processes to make information flow smoothly within organizations. Firms cannot realize expected returns from ERP investments unless changes are effectively managed after ERP systems are put into operation. The research model is empirically tested using data collected from over 170 firms that had used ERP systems at least for more than one year. Our analysis reveals that the eventual success of ERP systems depends on effective change management after ERP implementation, supporting the existence of the 'valley of despair.

Even though many projects of new development and redevelopment for information systems are invested, they are not taken care of from the perspective of administration and evaluation. Also, decision makers fall short of not only support the process to check alternatives and select an alternative for investment and but also provide necessary information so as to maximize the effects of investments. That is to say, the suggestion of general direction toward IT investment is debatable. Against this backdrop, we propose a value measurement model to manage information systems.
