This paper presents an original description and a semi-formal definition of the concept of a value proposition, which has been so far used in service science rather intuitively. Our approach is based on utility functions and conceptual modelling techniques. The proposed semi-formalization can be...

A method of small-area estimation with a utility function is developed. The utility characterises a policy planned to be implemented in each area, based on the area's estimate of a key quantity. It is shown by simulations that the commonly applied composite and empirical Bayes estimators are...

This paper analyzes how the indeterminacy of competitive equilibrium in one-sector growth models depends on the magnitude of the households' income effect on the demand for leisure. The paper first establishes that the presence of income effect is necessary for the existence of an indeterminate...

This note concerns Markov decision processes on a discrete state space. It is supposed that the reward function is nonnegative, and that the decision maker has a nonnull constant risk-sensitivity, which leads to grade random rewards via the expectation of an exponential utility function. The...

We identify necessary and sufficient conditions under which a finite data set of price vectors and consumption bundles can be rationalized by a weakly separable utility function.  Our result could be understood as a generalization of Afriat's Theorem.
