Prudence coefficient and precautionary savings [DD5] 7. This means that the higher the utility level the higher the item will be prioritized in the consumer’s budget. Preview: if your utility over monetary outcomes is concave in the amount of money, then you are risk-averse.

Drèze, A. Rustichini. probability theory In probability theory: An alternative interpretation of probability …that the individual has a utility function, which measures the value to him of each course of action when each of the uncertain possibilities is the true one, and a “subjective probability distribution,” which expresses quantitatively his beliefs about the uncertain situations.
