5) The questions in this part refer to the following diagram showing the costs and benefits of a particular type of medical testing: Marginal Benefits & Marginal Costs 10 Matging External Benefit Margin Private Benefit Quantity 10 produced & consumed 5a) Draw the marginal social benefit curve on the above diagram and label it MSB (if you do this in Word, you can use the draw tool, being careful to make the MSB a straight line (if you mess up, you can always undo )). [3 pts .] 5b) What will be the quantity of medical tests if markets are left on their own without outside intervention? What is the socially optimal level of tests? [2+2=4 pts .] 5c) On the diagram, in a different color (you can add more colored pens in Word by going to the Draw menu, adding a pen , then changing its color on the little drop -down arrow on the pen ), draw the deadweight loss triangle (a.k.a. the efficiency loss triangle ). Calculate deadweight loss by finding the area of that triangle . [2+2=4 pts . ] 5d) If a subsidy is given to all consumers in order to induce them to purchase the socially optimal level of medical tests , how big will that subsidy be (per consumer )? [3 pts.] 5e) On the diagram, in a different color, draw the MPB curve after the subsidy. [3 pts.]
