In a pilot study, we employed a series of novel economic games to investigate the underexplored behavioral aspects of security investment decisions and security investment structure decisions (i.e., budgeting the security expenditure among different types of security measures). In our study, decision makers exhibited a bias toward investing in prevention even though investing in detection and r...

In this paper, the investment portfolio is formed based on the data mining algorithm of CHAID on the basis of the risk status criteria. In the next step, the second investment portfolio is created based on the decision rules extracted by the DEA-BCC model. The final portfolio is created through a two-objective mathematical programming model based on the Imperialist Competitive algorithm.

We consider all or nothing investment problem with a finite time horizon when the investment opportunity set is changing stochastically over time, especially under Markovian regime-switching environment, and a decision maker faces ambiguity of parameters governing profit flow dynamics of the investment. We apply α-Maxmin Expected Utility(α-MEU) preferences to reflect the ambiguity seeking attit...

A multistage decision process for transportation investment planning is described. Most transportation investment problems inherently involve multiple criteria and uncertainty. To deal with the variations arising from changes in external environments, robust contingency plans should be integrated in the planning process-not after plans are developed-to account for uncertainty. With the proposed...

Purpose: In this paper we discuss how managers use knowledge when making ICT investment decisions. ICT investments are complex processes and have also strategic implications for organizations. The focus of the study is to reveal how the organizational process of knowledge creation affects the individual-level decision making and how knowledge conversions between tacit and explicit knowledge occ...

This paper experimentally investigates investment behavior. We find that global risk – i.e. risk independent of an agent’s investment decision (like political risk) – substantially decreases investment. Also, if the capital used for investment is based on previous earnings (effort) instead of an endowment, investment decreases substantially. These results are neither in line with expected utili...

An important class of investment decisions is characterized by unrecoverable sunk costs, resolution of uncertainty through time, and the ability to invest in the future as an alternative to investing today. The options model provides guidance in such settings, including an investment decision rule called the bad news principle: the downside investment state influences the investment decision, w...

this paper provides a fuzzy based decision support system (dss) for risk analysis in e-tourism ( electronic tourism ) investment. in general term, e-tourism is the use of information and communication technology (ict) in tourism which may allow operating tourism in least variable cost, least time and increased work efficiency. it is worth noting that there are many factors that affect the deve...
