Assume that Benedict's utility function is u(x, x)=xx. Suppose that, initially, both goods are $1 per unit and that his income is $80. Then, the price of the first good (p) rises to $4. Find the Hicksian substitution and income effects of this price change on the first good. Hint: First, find the optimal allocation at $1 for both goods and then the optimal allocation when good 1 costs $4.
