The Logic of Collective Action, Mancur Olson laid out the theory of "Concentrated Benefits and Dispersed Costs," by which Olson meant that well-organized groups who stand to lose or gain a great deal (usually, though not always, financially) if a certain government policy is changed will have more impact on the policy process than unorganized individuals whose interests oppose these organized groups and whose total numbers may be greater.
Need an example? Look no further than a decision this week by the South Korean Health Ministry to leave in place a restriction that allows over-the-counter drugs to be sold only in certified pharmacies (rather than allowing items such as aspirin, Tylenol, etc. to be sold in supermarkets). The Ministry - and the ruling Grand National Party - apparently balked at lifting this restriction in the face of pressure by the Korean Pharmaceutical Association (KPA).
According to the Joong-Ang Daily, the general public favors removing this restriction for the sake of convenience and even President Lee Myung-bak was upset by the Health Ministry's decision. Why, then, does the restriction remain?
Quite simply, the members of the KPA are well-organized and stand to lose a great deal of money if their monopoly on the sale of these drugs is removed. You can be damn sure, therefore, that they've spared no time or money in persuading the government to their way of thinking.
Individual consumers, meanwhile, continue to pay more for their Tylenol and are inconvenienced by having to find a pharmacy whenever they have a headache (heaven forbid they get that headache on Sunday, when most pharmacies are closed). These consumers, however are also busy people with jobs, families, and other demands on their time. In short, these individual customers have scant time to organize themselves and lobby the government in the hopes that such activity will save them a few minutes or a bit of money when they buy aspirin. Yet, when we add up the total cost inflicted upon all consumers by this restriction we see that such a restriction on the sale of OTC drugs does more social harm than good.
Show me a seemingly nonsensical government economic policy - protectionism, subsidies, etc. - and the odds are better than even that I can show you a case of concentrated benefits and dispersed costs.
