This paper shows that there is a positive and statistically significant correlation between the short-term discount rate over a monetary reward and the short-term discount rate over a primary reward (chocolate). This correlation, however, is absent among subjects who do not like chocolate and...

The main issue of this article is to discuss the question of ‘precarity’ in the context of the theory of social quality (see Beck et al, 2001), with which to pave the way for developing further the theoretical foundation of precarity. Societal practice is the main challenge this concept...

We reexamine the analysis of Chambers (Social Choice and Welfare, 2009), that produces a characterization of a family of social welfare functions in the context of intergenerational equity: namely, those that coincide with either the sup, inf, lim sup, or lim inf rule. Reinforcement, ordinal...

The paper critically discusses the issue of rationality and choices in economics in both the behavioural and evolutionary approaches. Our study aims, on the one hand, to highlight the scientific contributions of psychology in economics, since psychology, and with it the theoretical approach of...

We conduct an experiment to investigate the degree to which deviations from exponential discounting can be accounted for by the hypothesis of hyperbolic discounting. Subjects are asked to choose between an earlier or later payoff in a series of 40 choice questions. Each question consists of a...

This paper argues critically the issue of choices and rationality in economic models through a multidisciplinary analysis. First, the analysis aims at highlight the scientific contributions of psychology in economics, since psychology and the related approach of cognitive economics has made more...

Sexual assault and rape are among the least reported crimes in the United States. This paper hypothesizes that this reflects the psycho-social costs of reporting a rape or sexual assault, which, in turn, reflect the stigma suffered by rape and sexual assault victims. These costs will be highest...

The article describes “the theory of value depreciation” developed by the author. In accordance with this theory, economic growth takes place using two inter-connected phenomena: (a) reduction in time necessary to produce “the set of goods currently consumed” (first form of value...

An allocation's ordinal efficiency deficit (OED) is defined as the greatest ordinal efficiency loss that can result from its application. More precisely, an allocation's OED is the negative of the greatest total amount by which it may be stochastically dominated by another feasible allocation....

This article analyzes the effect of speculation on the economic welfare from various criteria, using a simple Edgeworth box within a three-period Walrasian competition framework. Here “speculation” is defined as a series of transition processes of each agent’s spontaneous production of...
