Suppose that the tofu industry is initially operating in long-run equilibrium at a price level of $5 per block of tofu and quantity of 150 million blocks per year. Suppose that the Food and Drug Administration (FDA) reports that compounds naturally occurring in tofu are linked to chronic illness. The FDA's research is expected to cause consumers to demand _ tofu at every price. In the short run, firms will respond by Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of the FDA's research. 10 O Supply Demand Supply PRICE (Dollars per block) w Demand N 30 60 0 120 150 180 210 240 270 300 QUANTITY (Millions of blocks) In the long run, some firms will respond by untilShift the demand curve, the supply curve, or both on the following graph to illustrate both the short-run effects of the FDA's research and the new long-run equilibrium after firms and consumers finish adjusting to the news. 10 O Supply Demand CO Supply 5 PRICE (Dollars per block) w Demand N 0 30 60 90 120 150 180 210 240 270 300 QUANTITY (Millions of blocks) The new equilibrium price and quantity suggest that the shape of the long-run supply curve in this industry is in the long run
