In cross-cultural psychology, uncertainty avoidance is how cultures differ on the amount of tolerance they have of unpredictability. [1] Uncertainty avoidance is one of five key qualities or dimensions measured by the researchers who developed the Hofstede model of cultural dimensions to quantify cultural differences across international lines and better understand why some ideas and business ...
In decision theory and economics, ambiguity aversion (also known as uncertainty aversion) is a preference for known risks over unknown risks.An ambiguity-averse individual would rather choose an alternative where the probability distribution of the outcomes is known over one where the probabilities are unknown.
Uncertainty avoidance (UAI): The uncertainty avoidance index is defined as "a society's tolerance for ambiguity", in which people embrace or avert an event of something unexpected, unknown, or away from the status quo. Societies that score a high degree in this index opt for stiff codes of behavior, guidelines, laws, and generally rely on ...
Upon graduating in Economics from Harvard in 1952, Ellsberg left immediately to serve as a US Marine before coming back to Harvard in 1957 to complete his post-graduate studies on decision-making under uncertainty. [10] Ellsberg left his graduate studies to join the RAND Corporation as a strategic analyst but continued to do academic work on ...
In economics, in 1921 Frank Knight distinguished uncertainty from risk with uncertainty being lack of knowledge which is immeasurable and impossible to calculate. Because of the absence of clearly defined statistics in most economic decisions where people face uncertainty, he believed that we cannot measure probabilities in such cases; this is ...
In economics and finance, risk aversion is the tendency of people to prefer outcomes with low uncertainty to those outcomes with high uncertainty, even if the average outcome of the latter is equal to or higher in monetary value than the more certain outcome. [1]
Regret theory is a model in theoretical economics simultaneously developed in 1982 by Graham Loomes and Robert Sugden, [1] David E. Bell, [2] and Peter C. Fishburn. [3] Regret theory models choice under uncertainty taking into account the effect of anticipated regret. Subsequently, several other authors improved upon it. [4]
In cognitive science and behavioral economics, loss aversion refers to a cognitive bias in which the same situation is perceived as worse if it is framed as a loss, rather than a gain. [ 1 ] [ 2 ] It should not be confused with risk aversion , which describes the rational behavior of valuing an uncertain outcome at less than its expected value .
