10.21. Figure 10.18 shows the supply and demand curves for cigarettes. The equilibrium price in the market is $2 per pack if the government does not intervene, and the quantity exchanged in the market is 1,000 million packs. Suppose the government has decided to discourage smoking and is considering two possible policies that would reduce the quantity sold to 600 million packs. The two policies are (i) a tax on cigarettes and (ii) a law setting a minimum price for cigarettes. Analyze each of the policies, using the graph and filling in the figure’s table.
