Question: Drug law enforcers can concentrate their efforts on reducing supply or demand, removing suppliers or removing demanders.
a. Assuming that your goal is to raise the price of drugs to a prohibitive level, should you pursue suppliers or users? What does your answer assume about elasticities of demand and supply?
b. If instead you want simply to reduce consumption and are uninterested in what happens to price, under what assumptions about elasticities should you target users rather than sellers?
