Why Regulation is Warranted • To provide information or to correct for the inability of consumers to make good decisions – Examples: restrictions on advertising of tobacco, warning labels, age restrictions • To deal with externalities (effects of a transaction that hurts or helps people who are not a part of that transaction) – Examples: drunk driving and second-hand smoke • Immorality of a good (not a justification economists often use) – Example: prohibition McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved.

A Twist on the Externalities Argument for Tobacco • Cigarette smokers are more likely to die – at an earlier age than they would have otherwise died. – in a less costly manner than they would have otherwise died. (e.g. heart attack rather than Alzheimer’s.) • Some economists estimate that this effect saves Social Security, Medicare and Medicaid (because they are not in nursing homes) more money than the $1 per pack in estimated external costs.

The Tobacco Settlement and Why Elasticity Matters • 1998 settlement between several states and several tobacco companies • $250 billion spread over 20 years • Demand for tobacco products is fairly inelastic. This means that the percentage change in prices will be more than the percentage reduction in smoking. McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved.

Elasticity Estimates • Elasticity of Demand – for Tobacco • -.2 for adults • -.5 for children – For Beer • -.53 • Implications – A dollar increase in the tax on cigarettes would reduce consumption by adults by 10% and reduce consumption by children by 25%.
