A consumer's utility function is -a u = x1x², where ₁ and 2 are the quantities consumed of goods one and two, respectively, and a is a parameter. Let p₁ and p2 denote the prices of goods one and two, respectively, so that the total expenditure in goods one and two is p₁1 + P2x2. The minimum expenditure that can be achieved subject to the constraint that the consumer achieves the level of utility ū is given by e = P₁P₂ 1-ªμа (this expression can be obtained by solving the corresponding constrained optimization problem). Calculate an approximation to the change in e due to increasing the level of utility by a small quantity d.

Mark is currently earning $44,000 a year. He has worked for this firm for 5 years. He is considering a job that will increase his lifetime earnings by $240,000 but that requires a Ph.D. in finance. The job will mean also attending a full-time finance program for four years at an annual cost of $28,500. Mark already completed an MBA, for which he spent $86,000 in tuition and books. Would he take the job and attend the Ph.D. program? Calculate: Insutructions: Use ono decimals. Use commas (30,000, not 30000). Opportunity costs of this decision = $ MC = $ MB = $ Sunk Costs = $
