The Economic Impact of Security Breaches on Publicly Traded Corporations: An Empirical Investigation

Abstract: In a 2008 survey of 522 computer security professionals, the Computer Security Institute found an average reported cost close to $500,000 for those companies that experienced a financial fraud. A survey of potential cloud computing adopters show that security and privacy are the primary concerns for not using the cloud. The present research conducts an event study to investigate the impact of publicly announced security breaches on the market value of the breached companies. We utilize the cumulative abnormal returns, risk shifts, and volume changes to measure this impact. Our results show that the cumulative abnormal return due to a security breach is -.19%. We also found the mean risk factor increases by about 22 percent. Our results also show an abnormal trading volume of about 6%. None of the previous research studies in the information systems area has investigated the impact of security breaches on cumulative abnormal returns, volume changes, and risk shifts.

ICT Diffusion at Developing Countries: The Role of Governance Types and Mechanisms

Abstract: The diffusion process of information and communication technology for mobile telephones, personal computers and internet users seems to follow the Bass’ diffusion model in most nations, but some of the factors affecting diffusion speeds are still unidentified. We focused on three geographical regions, of mostly developing nations namely: Eastern Europe, Southeast Asia, and Central America/Caribbean to compare diffusion speeds. We included economic wealth, social infrastructures, and governance mechanisms to measure their impact in the diffusion speed for a period of 20 years. Based on secondary data, we conclude that geographical location, financial status, social infrastructure and governance mechanisms impact diffusion speed of three ICT products (PC, mobile phones and Internet). Along with the economies, we discovered that the types of government (democratic, autocratic and communist), follow the same diffusion shape, but the speed of diffusion is greatly altered by governmental intrusion in this matter. Governance mechanisms also affect diffusion speed.

A Model to Develop Smart Energy Infrastructure in Latin America

Abstract: There exist many areas of interest to modernize the generation and distribution of electricity of Latin American countries. Since the liberalization of the energy supply activity in the 90’s, and the autonomy of regulation agencies, governments have been working along with private investors to enhance this market. In this paper, we develop a model that presents inputs, outputs and process elements to develop the infrastructure as foundation for smart energy provision in the developing countries of Latin America.

Comparing drivers, barriers, and opportunities of business models for renewable energies: A review

Abstract: This article systematically reviews the emerging field of research on business models for renewable energies, differentiating between developing and industrialized countries. The key findings on developing countries are as follows: first, there is a lack of quantitative data; second, opportunities are driven primarily by unfulfilled basic needs and micro-finance, whereas corruption and weak electricity grids are the main barriers; and third, business models should be replicable. The key findings on industrialized countries are as follows: first, opportunities are driven primarily by climate change mitigation and energy efficiency improvements; second, stuck thought patterns and high costs of energy storage are important barriers; and third, cooperation is a key in future business models to handle increasing complexity. This review reveals implications for researchers and policy-makers. Promising avenues for future research are the analysis of intermodal business models and opportunities concerning energy self-supply and renewable district heating. Policy-makers are advised to design legal frameworks that account for the global nature of the renewable energy challenge and are simultaneously adapted to regional disparities.

A review of optimal power flow studies applied to smart grids and microgrids

Abstract: The term smart grid refers to a modernization of the electrical network consisting in the integration of various technologies such as dispersed generation, dispatchable loads, communication systems and storage devices which operates in grid-connected and islanded modes. As a result, traditional optimization techniques in new power systems have been seriously influenced during the last decade. One of the most important technical and economical tools in this regard is the Optimal Power Flow (OPF). As a fundamental optimization tool in the operation and planning fields, OPF has an undeniable role in the power system. This paper reviews and compares the OPF approaches mainly related to smart distribution grids. In this work, the main OPF approaches are compared in terms of their objective functions, constraints, and methodologies. Furthermore, computational performances, case study networks and the publication date of these methods are reported. Finally, some basic challenges arising from the new OPF methodologies in smart grids are addressed.
