Consider public policy aimed at smoking. a. Studies indicate that the price elasticity of demand for cigarettes is about $0.4 .$ If a pack of cigarettes currently costs $\$ 5$ and the government wants to reduce smoking by 20 percent, by how much should it increase the price? b. If the government permanently increases the price of cigarettes, will the policy have a larger effect on smoking 1 year from now or 5 years from now? c. Studies also find that teenagers have a higher price elasticity of demand than adults. Why might this be true?

Key Concepts

Time Horizon Effects in Elasticity

The responsiveness of consumers to price changes can vary over time, with long-run elasticities generally being higher than short-run elasticities. This concept is important when considering policies that permanently raise prices; over time, consumers have more opportunities to adjust their behavior, such as quitting smoking or finding alternatives, thereby enhancing the policy’s effectiveness.

Differential Price Elasticity Among Demographics

Different demographic groups can have varying sensitivity to price changes due to factors like income levels, social habits, or addiction vulnerability. For instance, teenagers often exhibit a higher price elasticity for cigarettes compared to adults, possibly because they have less disposable income and are more responsive to price variations. Understanding these differences is key for tailoring public policies to target specific groups effectively.

Price Elasticity of Demand

Price elasticity of demand measures the percentage change in the quantity demanded of a good in response to a one-percent change in its price. This concept is crucial for understanding how consumers adjust their consumption patterns as prices vary, which is fundamental for designing effective public policies, such as those aimed at reducing smoking through price increases.

Impact of Price Changes on Consumption

This concept refers to the relationship between the price of a product and the amount consumers purchase. In public policy, increasing the price of harmful products like cigarettes is a strategy to reduce consumption. The calculation of the required price increase, based on elasticity, helps policymakers estimate the likely reduction in consumption resulting from a targeted price hike.
