  • General Form of a Quasi-Linear Utility Function

Marginal Utility of Income in a Quasi-Linear Function

For a quasi-linear utility function of the general form u(x,m)=v(x)+mu(x, m) = v(x) + m, where mm represents income, the marginal utility of income is constant and equal to 1. This is determined by calculating the partial derivative of the utility function with respect to income: ∂u∂m=1\frac{\partial u}{\partial m} = 1.

  • A consumer's preferences are described as 'quasi-linear' if the utility function is linear with respect to one good (typically representing all other consumption) and non-linear with respect to another. A key implication of this form is that the marginal utility of the non-linear good does not depend on the quantity of the linear good. Given this information, which of the following utility functions, u(x, m), represents quasi-linear preferences where x is a specific good and m is money spent on all other goods?

  • A consumer's preferences for a specific good x and money m (representing all other consumption) are described by the utility function u(x, m) = 10√x + m. By analyzing the properties of this function, which statement accurately describes the consumer's behavior or preferences?

  • Consider a consumer whose preferences for a specific good, x, and money available for all other goods, m, can be represented by the utility function u(x, m) = 20 * ln(x) + m. According to this model, if the consumer's income increases, their willingness to pay for an additional unit of good x will also increase.

  • A utility function of the form u(x, m) = v(x) + m is said to represent 'well-behaved' quasi-linear preferences. For this to be true, the utility from good x must be increasing (meaning its first derivative, v'(x), is positive), and there must be diminishing marginal utility for good x (meaning its second derivative, v''(x), is negative), for all x > 0. Which of the following specifications for v(x) satisfies both of these conditions?

  • An individual's preferences are modeled by a utility function u(x, m), where x is the quantity of a specific good and m is the amount of money available for all other goods. Match each utility function to the statement that correctly describes its marginal utility properties.

  • A utility function of the form u(x, m) = v(x) + m is referred to as 'quasi-linear' because while it is typically non-linear with respect to good x, it is perfectly linear with respect to the variable ______, which represents an individual's income available for other goods.

  • Derivation of the MRS for a Quasi-Linear Utility Function

  • A consumer's preferences are represented by the utility function u(x, m) = 10√x + m, where 'x' is the quantity of a good and 'm' is the amount of money available for other goods (income). How does the additional utility the consumer gains from one extra dollar change as their initial amount of money 'm' increases?

  • Consider a consumer whose preferences for a good (x) and money for other goods (m) can be represented by a utility function of the form u(x, m) = v(x) + m. For this consumer, the additional satisfaction gained from one extra dollar of income will decrease as their total income (m) increases.
