We introduce a new solution concept for games in extensive form with perfect information: the valuation equilibrium. The moves of each player are partitioned into similarity classes. A valuation of the player is a real valued function on the set of her similarity classes. At each node a player chooses a move that belongs to a class with maximum valuation. The valuation of each player is consist...

This paper analyzes the impact of model complexity on the net present value distribution and the expected default probability of equity investments in project finance. Model complexity is analyzed along two dimensions: simulation complexity and forecast complexity. We aim to identify model elements which are crucial for the valuation of project finance in practice. First, we present a simulatio...

the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

Valuation of information systems (IS) and information technology (IT) has gained a lot of attention over the years resulting in a broad range of approaches. We examine the use of valuation methods in a case study of a large public organization. Life cycle analysis was used to position and relate valuation methods. We found that eight different methods were used and that there was limited coordi...

Using landscape analysis and economic valuation, this article shows how valuation techniques can inform prioritization of private forestland for ecosystem service conservation and highlights the methodological challenges in doing so. We classify forests according to six ecological and social characteristics. If ecosystem service priorities are known a priori, this landscape analysis might be su...

OBJECTIVE To review the use of measures of health status in the assessment of benefits in economic evaluation, whether or not the measures were designed for this purpose. METHODS The review was based on a systematic search of the literature. It provides a comprehensive assessment of the evidence where it exists and a balanced overview of opinion otherwise. RESULTS Over 3000 papers were iden...

BACKGROUND The EQ-5D is a preference based instrument which provides a description of a respondent's health status, and an empirically derived value for that health state often from a representative sample of the general population. It is commonly used to derive Quality Adjusted Life Year calculations (QALY) in economic evaluations. However, values for health states have been found to differ be...

OBJECTIVE A new methodology is introduced to scale health states on an interval scale based on similarity responses. It could be well suited for valuation of health states on specific regions of the health continuum that are problematic when applying conventional valuation techniques. These regions are the top-end, bottom-end, and states around 'dead'. METHODS Three samples of approximately 5...

Valuation algebras are known to present a common roof over various applications out of different domains of research. In combination with the power of local computation it offers a possibility to solve inference problems in an efficient way. Implementing concretely these concepts by instantiating a valuation algebra means loosing the high level of abstraction. This paper presents a generic real...

To make a decision, a system must assign value to each of its available choices. In the human brain, one approach to studying valuation has used rewarding stimuli to map out brain responses by varying the dimension or importance of the rewards. However, theoretical models have taught us that value computations are complex, and so reward probes alone can give only partial information about neura...
