Some consumers fail to observe shrouded product attributes when they buy a new product. For example, an account holder may not know their bank's fee schedule. Firms will choose high shrouded fees and compete to attract consumers with loss-leader base goods: e.g., banks will offer free gifts for...

Conventional theory explains moral hazard as a consequence of information asymmetries. The present paper proposes an alternative approach. We argue that information asymmetries are just one among several causes of moral hazard and that they entail negative consequences for third parties only...

Risk aversion is traditionally defined in the context of lotteries over monetary payoffs. This paper extends the notion of risk aversion to a more general setup where outcomes (consequences) may not be measurable in monetary terms and people may have fuzzy preferences over lotteries, i.e. they...

This note provides an axiomatic derivation of a case-based decision rule. It shows that, if preferences orders over available acts in various contexts satisfy certain consistency requirements, then these orders can be numerically represented by maximizationof a similarity-weighted utility function.

This paper derives a representation of preferences for a choice theory with vague environments; vague in the sense that the agent does not know the precise lotteries over outcomes conditional on states. Instead, he knows only a possible set of these lotteries for each state. Thus, this paper's...

Loss aversion is traditionally defined in the context of lotteries over monetary payoffs. This paper extends the notion of loss aversion to a more general setup where outcomes (consequences) may not be measurable in monetary terms and people may have fuzzy preferences over lotteries, i.e. they...

Define the riskiness of a gamble as the reciprocal of the absolute risk aversion (ARA) of an individual with constant ARA who is indifferent between taking and not taking that gamble. We characterize this index by axioms, chief among them a "duality" axiom which, roughly speaking, asserts that...

The increase of spendings with the prices of raw materials, energy and fuel has eventually, and almost inevitably, led to an unexpected rise in the demand for currency, a demand coming from the goods and services suppliers. The resulting effect was the surging of an accelerated inflationist...

Este breve artículo glosa algunas de las aplicaciones recientes de sistemas dinámicos estocásticos de la Teoría de Juegos y la Economía. El modelo que se describe con más detalle demuestra que la única asignación estocásticamente estable de un proceso de intercambio entre coaliciones...

Accounting information is processed by decision makers guided by their particular need to support decisions. The Throughput Modeling approach to ethics provides a way of dealing with accounting information processed through various pathways by dec ision makers. This modeling approach captures...
