Plain-text version
In a two-good world, a consumer's preferences over commodities 1 and 2 can be represented by the utility function U(x₁, x₂) = v(x₁) + x₂, where x₁, x₂ ≥ 0. The consumer's income is known to be very high. Then, the demand for good 1 displays which of the following? (A) The substitution effect is negative and the income effect is positive (B) The substitution effect is positive and the income effect is negative (C) The substitution effect is zero and the income effect is positive (D) The substitution effect is negative and there are no income effects
Also written as: In a two-good world, a consumer's preferences over commodities 1 and 2 can be represented by the utility function U(x_1, x_2) = v(x_1) + x_2, where x_1, x_2 >= 0. The consumer's income is known to be very high. Then, the demand for good 1 displays which of the following?
