This research evaluated what ammonia concentration causes pullets or young laying hens to show an aversion. Because previous studies had shown conflicting data for laying hen aversion at 25 ppm ammonia, this aversion was tested with pullets and young laying hens in the current study. The test birds used in this study had not previously experienced elevated ammonia concentrations and thus their ...

The phenomenon of ambiguity aversion, in which risky gambles with known probabilities are preferred over ambiguous gambles with unknown probabilities, has been thoroughly documented in adults but never measured in children. Here, we use two distinct tasks to investigate ambiguity preferences of children (8- to 9-year-olds) and a comparison group of adults (19- to 27-year-olds). Across three sep...

The Nash equilibrium solution concept for games is based on the assumption of expected utility maximization. Reference dependent utility functions (in which utility is determined not only by an outcome, but also by the relationship of the outcome to a reference point) are a better predictor of behavior than expected utility. In particular, loss aversion is an important element of such utility f...

This paper focuses on the study of decision making under risk. We, first, recall some model-free definitions of risk aversion and increase in risk. We propose a new form of behavior under risk that we call anti-monotone risk aversion (hereafter referred to as ARA) related to the concept of anti-comonotony a concept investigated in Abouda, Aouani and Chateauneuf (2008). Note that many research h...

We focus on automatic strategies to optimize life cycle savings and investment. Classical optimal savings theory establishes that, given the level of risk aversion, a saver would keep the same relative amount invested in risky assets at any given time. We show that, when optimizing lifecycle investment, performance and risk assessment have to take into account the investor's risk aversion and t...

Inequality Aversion and Risk Attitudes Using self reported measures of life satisfaction and risk attitudes, we empirically test whether there is a relationship between individuals inequality and risk aversion. The empirical analysis uses the German SOEP household panel for the years 1997 to 2007 to conclude that the negative effect of inequality measured by the sample gini coefficient by year ...

Of a randomly selected sample of 214 patients treated with aversion therapy for cocaine dependence in four chemical dependency units operated by Schick Shadel Hospitals, 156 were followed up 12 to 20 months posttreatment (average 15.2 months). Significant other validation was obtained in 33%. Total abstinence from cocaine for the group overall was 53% at one year post treatment, and current abs...
