The Benefits of Consumer Protection

15 一月, 2016 - 09:47

Consumer protection laws are generally based on one of two conceptual arguments. The first holds that consumers do not always know what is best for them. This is the view underlying government efforts to encourage the use of merit goods and discourage the use of demerit goods. The second suggests that consumers simply do not have sufficient information to make appropriate choices.

Laws prohibiting the use of certain products are generally based on the presumption that not all consumers make appropriate choices. Drugs such as cocaine and heroin are illegal for this reason. Children are barred from using products such as cigarettes and alcohol on grounds they are incapable of making choices in their own best interest.

Other regulations presume that consumers are rational but may not have adequate information to make choices. Rather than expect consumers to determine whether a particular prescription drug is safe and effective, for example, federal regulations require the Food and Drug Administration to make that determination for them.

The benefit of consumer protection occurs when consumers are prevented from making choices they would regret if they had more information. A consumer who purchases a drug that proves ineffective or possibly even dangerous will presumably stop using it. By preventing the purchase in the first place, the government may save the consumer the cost of learning that lesson.

One problem in assessing the benefits of consumer protection is that the laws themselves may induce behavioral changes that work for or against the intent of the legislation. For example, requirements for childproof medicine containers appear to have made people more careless with medicines. Requirements that mattresses be flame-resistant may make people more careless about smoking in bed. In some cases, then, the behavioral changes attributed to consumer protection laws may actually worsen the problem the laws seek to correct.

An early study on the impact of seat belts on driving behavior indicated that drivers drove more recklessly when using seat belts, presumably because the seat belts made them feel more secure. Sam Peltzman, “The Effects of Automobile Safety Regulations,” Journal of Political Economy 83 (August 1975): 677–725. A recent study, however, found that this was not the case and suggests that use of seat belts may make drivers more safety-conscious. Alma Cohen and Liran Einan, “The Effects of Mandatory Seat Belt Laws on Driving Behaviour and Traffic Fatalities,” Review of Economics and Statistics 85:4 (November 2003): 828–43.

In any event, these “unintended” behavioral changes can certainly affect the results achieved by these laws.
