1. Suppose Congress, influenced by studies linking cigarette smoking to cancer, plans to raise the excise tax on cigarettes so the price rises by 10%. Estimate the effect the price increase will have on cigarette consumption and consumer spending on cigarettes (in percentage terms).
2. Suppose a major brokerage firm advised its clients to buy cigarette stocks under the assumption that, if consumer incomes rise by 50% as expected over the next decade, cigarette sales will double. What is your reaction to this investment advice?
