  2. Indifference curve - Wikipedia

    en.wikipedia.org/wiki/Indifference_curve

    The negative slope of the indifference curve reflects the assumption of the monotonicity of consumer's preferences, which generates monotonically increasing utility functions, and the assumption of non-satiation (marginal utility for all goods is always positive); an upward sloping indifference curve would imply that a consumer is indifferent ...

  3. Corner solution - Wikipedia

    en.wikipedia.org/wiki/Corner_solution

    When the slope of the indifference curve is greater than the slope of the budget line, the consumer is willing to give up more of good 1 for a unit of good 2 than is required by the market. Thus, it follows that if the slope of the indifference curve is strictly greater than the slope of the budget line:

  4. Marginal rate of substitution - Wikipedia

    en.wikipedia.org/wiki/Marginal_rate_of_substitution

    For example, if the MRS xy = 2, the consumer will give up 2 units of Y to obtain 1 additional unit of X. As one moves down a (standardly convex) indifference curve, the marginal rate of substitution decreases (as measured by the absolute value of the slope of the indifference curve, which decreases).

  5. Markowitz model - Wikipedia

    en.wikipedia.org/wiki/Markowitz_model

    Indifference curves C 1, C 2 and C 3 are shown. Each of the different points on a particular indifference curve shows a different combination of risk and return, which provide the same satisfaction to the investors. Each curve to the left represents higher utility or satisfaction. The goal of the investor would be to maximize their satisfaction ...

  6. Robinson Crusoe economy - Wikipedia

    en.wikipedia.org/wiki/Robinson_Crusoe_economy

    At this equilibrium point, the slope of the highest indifference curve must equal the slope of the production function. Recall that the marginal rate of substitution is the rate at which a consumer is ready to give up one good in exchange for another good while maintaining the same level of utility. [ 6 ]

  7. Risk aversion - Wikipedia

    en.wikipedia.org/wiki/Risk_aversion

    Right graph: With fixed probabilities of two alternative states 1 and 2, risk averse indifference curves over pairs of state-contingent outcomes are convex. 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 ...

  8. Linear utility - Wikipedia

    en.wikipedia.org/wiki/Linear_utility

    The indifference curves are straight lines (when there are two goods) or hyperplanes (when there are more goods). Each demand curve (demand as a function of price) is a step function : the consumer wants to buy zero units of a good whose utility/price ratio is below the maximum, and wants to buy as many units as possible of a good whose utility ...

  9. Consumer choice - Wikipedia

    en.wikipedia.org/wiki/Consumer_choice

    For example, every point on the indifference curve I1 (as shown in the figure above), which represents a unique combination of good X and good Y, will give the consumer the same utility. Indifference curves have a few assumptions that explain their nature. Firstly, indifference curves are typically convex to the origin of the graph.
