In economics, a random utility model (RUM), [1] [2] also called stochastic utility model, [3] is a mathematical description of the preferences of a person, whose choices are not deterministic, but depend on a random state variable.
where t is time, f is a deterministic function, and e t is a zero-long-run-mean stationary random variable. In this case the stochastic term is stationary and hence there is no stochastic drift, though the time series itself may drift with no fixed long-run mean due to the deterministic component f ( t ) not having a fixed long-run mean.
An econometric model specifies the statistical relationship that is believed to hold between the various economic quantities pertaining to a particular economic phenomenon. An econometric model can be derived from a deterministic economic model by allowing for uncertainty, or from an economic model which itself is stochastic. However, it is ...

Encouraging Healthy Eating Behaviors Despite the focus of current and past legislation on providing information, there is little evidence that doing so has much impact.
In other words, someone who has more money has a lower desire for a fixed amount of gain (and lower aversion to a fixed amount of loss) than someone who has less money. The theory continues with a second concept, based on the observation that people attribute excessive weight to events with low probabilities and insufficient weight to events ...
