Suppose that the preceding equilibrium is disturbed by an outward shift in the drink market demand curve so that 5200 more cups per day are demanded at every price. The equation for this new relationship is Q = 12,400 - 40F. In the short run following this demand shift, industry production expands because the rms already in the industry increase Their variable factors. There is no increase in their xed factors and no new rms enter the industry. (Recall that the short-run cost structure of the representative rrn in the industry is shown in Figure A.) 19. Plot and label the original (Do) and new (Dl) demand curves in Figure C. (For best results, make each vertical axis unit 10 and each horizontal axis unit 400. The vertical intercept of D1 will not t on your graph. Don't worry about it.) 20. Plot and label the industry long-run supply curve (LRS) in Figure C. 21. Label the original long-run market equilibrium point E0 in Figure C. 22. The industry short-run supply (SR5) is Q = 90P - 4500. It is obtained by summing the individual supply curves (i.e., the MC curves) of the No firms in the initial long-rim equilibrium. Plot and label this relationship in Figure C. 23. What are market price and quantity in the intermediate short-um equilibrium? 25. How many active rms are there in the industry? How much is each producing
