9.8 Public Goods and National Security LEARNING OBJECTIVES 1. Learn that public goods, which have the features of being nonrival and nonexcludable in consumption, are a type of market imperfection. 2. Recognize that a trade policy can be used to correct for a public good imperfection. 3. Learn the first-best and second-best policy options to correct for a public good imperfection. One of the oldest and most common arguments supporting protection is the “national security argument,” also called the “national defense argument.” This argument suggests that it is necessary to protect certain industries with a tariff to assure continued domestic production in the event of a war. Many products have been identified as being sufficiently important to warrant protection for this reason. Perhaps the most common industry identified is agriculture. Simply consider the problems that would arise if a nation did not have an adequate food supply when it was at war with the outside world. Low food stocks may induce severe hardships and even famine. A simple solution to avoid this potential problem is to maintain a Saylor URL: http://www.saylor.org/books Saylor.org 489
sufficiently high tariff in order to keep cheap foreign goods out and, in turn, maintain production of the domestic goods. Similar problems may arise in many other industries. Consider the potential problems for a country’s national security if it could not produce an adequate amount of steel, aluminum, ships, tanks, planes, fuel, and so on in the event of a war. The number of products that could be added to this list is enormous. Indeed, at one time or another in most countries’ histories, it has been argued that almost every product imaginable is important from a national security perspective and thus is deserving of protection. One of the most interesting arguments ever described is that made by the embroidery industry, which once argued for a protective tariff in the United States because embroidered patches on soldiers’ uniforms are essential in maintaining the morale of the troops. Thus it was clear, to them at least, that the embroidery industry needed to be protected for national security reasons. National Security and Public Goods We can make better sense of the national security argument if we classify it in the context of the theory of the second best. In this case, we must note that the national security argument is actually incorporating a market imperfection into the story to justify the use of a protective tariff. The market imperfection here is a public good. National security is a public good and public goods are excluded from the standard assumptions of perfect competition. Thus, whenever a product has public good characteristics, we can say that a market imperfection is present. Traditionally, the literature in economics refers to concerns such as national security as noneconomic objectives. The effects that food production may have on the nation’s sense of security, for example, were thought to fall outside the realm of traditional economic markets. In general, public goods have the following two consumption characteristics: they are nonexcludable and they are nonrival. Nonexcludability means that once the product is produced, it is impossible to prevent people from consuming it. Nonrivalry means that many people can consume the produced product without diminishing its usefulness to others. Here are a few examples to explain the point. First, consider a nonpublic good: soda. A soda is excludable since the producer can put it into a can and require you to pay for it to enjoy its contents. A can of soda is also a rival good. That’s because if you consume the can of soda, there is no way for anyone else to consume the same can. This implies that a can of soda is not a public good. On the other hand, consider oxygen in the atmosphere. (This is an odd example because oxygen in the air is not formally produced, but let’s ignore that for a moment.) Atmospheric oxygen is Saylor URL: http://www.saylor.org/books Saylor.org 490
