JNU SSS 2012 Question 86: Demand theory and elasticity

Suppose a consumer's preferences over commodities 1 and 2 can be represented by the utility function U(x1, x2)=min⁡{x1, x2}U(x_1,\ x_2) = \min \{x_1,\ x_2\}U(x1​, x2​)=min{x1​, x2​}, where x1, x2≥0x_1,\ x_2 \geq 0x1​, x2​≥0. The prices of the two commodities are 1 and 2 respectively and the consumer's income is 150.

Suppose the price of commodity 2 reduces to 1 while the price of the other commodity and the consumer's income remain unchanged. The income effect according to Slutsky of this price change on the optimal amount of commodity 1 is

Plain-text version

Suppose a consumer's preferences over commodities 1 and 2 can be represented by the utility function U(x₁, x₂) = min {x₁, x₂}, where x₁, x₂ ≥ 0. The prices of the two commodities are 1 and 2 respectively and the consumer's income is 150. Suppose the price of commodity 2 reduces to 1 while the price of the other commodity and the consumer's income remain unchanged. The income effect according to Slutsky of this price change on the optimal amount of commodity 1 is (A) 0 (B) 25 (C) -25 (D) -1

Also written as: Suppose a consumer's preferences over commodities 1 and 2 can be represented by the utility function U(x_1, x_2) = min {x_1, x_2}, where x_1, x_2 >= 0. The prices of the two commodities are 1 and 2 respectively and the consumer's income is 150. Suppose the price of commodity 2 reduces to 1 while the price of the other commodity and the consumer's income remain unchanged. The income effect according to Slutsky of this price change on the optimal amount of commodity 1 is
