Consider a consumer with utility U(x) = log x₁ + √x2 for 2-good bundles. 1. Are the consumer's preferences homothetic? If so, prove it. If not, provide a coun- terexample. 2. Calculate the Marshallian demand for each good, as a function of prices and wealth. 3. Plot the Engel curve for each good when p = (1, 1). (Each plot should represent wealth on the horizontal axis and quantity on the vertical axis.) 4. Suppose that p = (1, 1). At what (positive) wealth level does the consumer purchase equal quantities of the two goods?

Question
Consider a consumer with utility U(x) = log x₁ + √x2 for 2-good bundles.
1. Are the consumer's preferences homothetic? If so, prove it. If not, provide a coun-
terexample.
2. Calculate the Marshallian demand for each good, as a function of prices and wealth.
3. Plot the Engel curve for each good when p = (1, 1). (Each plot should represent wealth
on the horizontal axis and quantity on the vertical axis.)
4. Suppose that p
=
(1, 1). At what (positive) wealth level does the consumer purchase
equal quantities of the two goods?
