Utility function is the most important concept in economic theory. In academic literature, utility functions can take … various forms. We prove that under a very general condition, utility function is the logarithmic function …

This note considers a hypothetical experiment designed to give meaning to the concept of one "type" of utility function … that are indeed non-comparable, as contemporary economic theory holds, there also exists a class of preferences that can be …

separable utility. Applications of weighted utility can be found in choice under risk (expected utility) and uncertainty … (subjective expected utility), intertemporal choice (discounted utility) and welfare economics (utilitarian social welfare … function). This paper presents an improved behavioral characterization (preference axiomatization) of weighted utility. It is …

This paper proposes a new unified voter utility function with both proximity and directional components. This improved … unified spatial voter utility function enables researchers to predict voter choices from survey data and test the relative … utility function is normalized to facilitate comparisons between voter groups and to estimate the likelihood of voting, able …

In this paper a generalized decomposable multiattribute utility function (MAUF) is developed. It is demonstrated that … simplify its structure or assessment. The concept of utility efficiency is developed to identify efficient alternatives when …

independent, so agents can aggregate the utilities of the issue values by simple summation, producing linear utility functions. In … interdependent, resulting in nonlinear utility functions. In this paper, we address this important gap in current negotiation … outperforms existing methods in large nonlinear utility spaces like those found in real world contexts. Further, we show that our …

based on the same price-dependent utility function. The alleged price dependence, however, is fictitious in the sense that … from Dusansky's utility function are identical and observationally equivalent to the demand functions obtained from a … prototypical utility function. Since all the market and environmental effects are revealed only through the demand functions, the …

This paper presents an approach, building on techniques from computational geometry, for compiling nonmonotonic utility … functions into a form that substantially speeds utility calculation. We demonstrate speedups of up to 70x in our experimental …
