Expected utility of net present value is the practitioner's approach to incorporate risk aversion into the evaluation of a project's cash flows. The discount rate and the convergence with the risk-neutral beta-adjusted approach from finance have always been a question. To fill this gap, we adopt...

Problem Definition: Project managers are responsible for setting and then revising projects' goals. As uncertainty related to project performance is resolved, a project manager is tasked with comparing ongoing costs, and potentially achieved scope, to a baseline plan. We question whether project...

Models where current utility depends solely on current consumption (a.k.a. time separable preferences) are widely acknowledged to be unrealistic, specially to describe preferences over consumption rates. Alternatively, one may stipulate that instant utility also depends on a state, e.g., some...

Why do we believe that more money will buy us more happiness (when in fact it does not)? In this paper, we propose a model to explain this puzzle. The model incorporates both adaptation and social comparison. A rational person who fully accounts for the dynamics of these factors would indeed buy...

Using a survey study of 261 decisions under uncertainty, we explore the factors that explain risk taking behavior and those that predict the importance of a decision. We also examine the relationship between framing and status quo, the similarity between monetary and non-monetary decisions, as...

We introduce a modification of the discounted utility model that accounts for both habituation and satiation in intertemporal choice. Habituation level and satiation level are state variables that induce changes in preferences as those states vary. We examine several properties of our model,...

We consider a resource allocation problem in which time is the principal resource. Utility is derived from time-consuming leisure activities, as well as from consumption. To acquire consumption, time needs to be allocated to income generating activities (i.e., work). Leisure (e.g., social...

Several studies have reported high performance of simple decision heuristics multi-attribute decision making. In this paper, we focus on situations where attributes are binary and analyze the performance of Deterministic-Elimination-By-Aspects (DEBA) and similar decision heuristics. We consider...
