(c) (Points: 8) Now let firms freely enter and exit. Solve for the long run partial equilibrium. Answer:(d) (Points: 10) Graph the aggregate demand curve, short run aggregate supply curve, and the long run aggregate supply curve on a qp -diagram. Be sure to label the graph clearly. Hint: Draw the aggregate supply and demand as price as a function of quantity. Answer:3. (POINTS: 40) Consider an economy there are 4 consumers and they each have the following demand function q"(p) =82.5-p There are many identical firms that produce this good according to the cost function C(q) = 11q- -6q+99 to maximize profits. (a) (Points: 4) What is the aggregate demand function Q"(p) for this economy? Answer: (b) (Points: 8) Suppose in the short run, there are / = 89 firms. Solve for the short run partial equilibrium. Be sure to setup the firms profit maximization problem over quantity and also check if the firms will shutdown in the short run
