where r is the risk-free rate, (μ, σ) are the expected return and volatility of the stock market and dB t is the increment of the Wiener process, i.e. the stochastic term of the SDE. The utility function is of the constant relative risk aversion (CRRA) form: =.
First, let one good be an example market e.g., carrots, and let the other be a composite of all other goods. Budget constraints give a straight line on the indifference map showing all the possible distributions between the two goods; the point of maximum utility is then the point at which an indifference curve is tangent to the budget line ...
The Dow Jones Utility Average (DJUA, also known as the "Dow Jones Utilities") is a stock index from S&P Dow Jones Indices that tracks the performance of 15 prominent utility companies traded in the United States.
σ M = standard deviation of the market portfolio σ P = standard deviation of portfolio (R M – I RF)/σ M is the slope of CML. (R M – I RF) is a measure of the risk premium, or the reward for holding risky portfolio instead of risk-free portfolio. σ M is the risk of the market portfolio. Therefore, the slope measures the reward per unit ...

The classic counter example to the expected value theory (where everyone makes the same "correct" choice) is the St. Petersburg Paradox. [3] In empirical applications, several violations of expected utility theory are systematic, and these falsifications have deepened our understanding of how people decide.
The graph shows the maximum amount of one person's utility given each level of utility attained by all others in society. [1] The utility–possibility frontier (UPF) is the upper frontier of the utility possibilities set, which is the set of utility levels of agents possible for a given amount of output, and thus the utility levels possible in ...
