utility functions are not concave-shaped but S-shaped. We justify the S shape using consumption-based asset pricing. We show … that various consumption-based asset pricing puzzles arise from the global concavity of the utility functions, and the S …-shaped consumption utility offers a solution. Also, the S-shaped utility helps explain the low elasticity of intertemporal substitution …

In this paper, we apply stochastic maximum principles to derive representations for exponential utility indifference … prices. We also obtain the related optimal portfolio processes and utility indifference hedging strategies. To illustrate our … theoretical results, we present several concrete examples and study the limit behavior of utility indifference prices for …

Utility tokens are digital currencies that serve as the only accepted means of payment for services and products …’s issuance, distribution, allocation, and potential destruction. The chapter describes utility tokens, compares them with other … tokenomic designs, discusses different regulatory approaches, and provides examples of current utility token applications in …

This paper introduces the concept of range-dependent utility. Instead of reference dependence which evaluates outcomes … decision maker is a fully rational expected utility maximizer only within a certain range. Range-dependent utility enables …-dependent utilities can be normalized to obtain decision utility -- a single utility function able to describe decisions involving …

A number of authors have suggested that investors derive utility from realizing gains and losses on assets that they … own. We present a model of this quot;realization utility,quot; analyze its predictions, and show that it can shed light on …

symmetry if the latter is generated by a field. Moreover, solving the PDEs yields the functional form for utility equivalent to …, multivariate separability, and homogeneity, including the cases of Cobb-Douglas and CES utility. …
