The importance of information as a resource and competitive factor in today’s society and economy is constantly rising. As a consequence, it becomes necessary for organizations to manage the risks that arise from poor information quality (IQ) in the same way other operational and strategic risks are managed. Information is, however, an unique and intangible resource that requires special method...

The correspondence of competitive partial equilibrium with a social optimum is well documented in the welfare theorems of economics. These theorems can be applied to single-period electricity pool auctions in which price-taking agents maximize profits at competitive prices, and extend naturally to standard models with locational marginal prices. In hydro-thermal markets where the auctions are r...

This paper considers the impact of information systems (IS) solutions on creativity and innovation within organizations and the associated role of risk assessment. It does this through an analysis of the results of two diverse studies. The studies are, respectively, an investigation of the relationship between the intention behind the initiation of an IS project and the post-implementation effe...

The aim of this paper is to propose a method for the evaluation of tunnel safety using probabilistic risk assessment. The framework includes three criteria; personal-, societal-and economic risk. The use of personal and societal risk is becoming more and more widespread. There are however, still some difficulties in using the economic risk criterion. Thus, as a first step towards economic risk ...

Information security professionals have to assess risk in order to make investment decisions on security measures. To investigate whether professionals make such decisions optimally, we conduct an online experiment and survey measuring risk attitudes of security professionals. Participants were asked to state their willingness-topay to avoid a series of losses-only lotteries and to make choices...

This paper reviews the state of the art in cyber security risk assessment of Cloud Computing systems. We select and examine in detail the quantitative security risk assessment models developed for or applied especially in the context of a Cloud Computing system. We review and then analyze existing models in terms of aim; the stages of risk management addressed; key risk management concepts cove...

We show that the dividend growth rate implied by the futures market is informative about (i) the expected dividend growth rate and (ii) the expected dividend risk premium. We model the dividend risk premium and explore its implications for the predictability of dividend growth and aggregate stock returns. We show that accounting for the dividend risk premium strengthens the predictability of di...

In the world of permanent cyber attacks to ICT systems, risk management is becoming a crucial task for minimization of the potential risks that can endeavor their operation. The prevention of the heavy losses that may happen due to cyber atta...
