## Flaws in the Democratic System of Government

Most developed countries today have a democratic system of government: citizens express their opinions through votes and those votes affect the direction of the country. The advantage of democracy over other systems is that it allows everyone in a society an equal say and therefore may reduce the possibility of a small group of wealthy oligarchs oppressing the masses. There is no such thing as a perfect system, and democracy, for all its popularity, is not without its problems, a few of which we will examine here.
We sometimes sum up and oversimplify democracy in two words: “Majority rule.” When voters face three or more choices, however, then voting may not always be a useful way of determining what the majority prefers.
As one example, consider an election in a state where 60% of the population is liberal and 40% is conservative. If there are only two candidates, one from each side, and if liberals and conservatives vote in the same 60–40 proportions in which they are represented in the population, then the liberal will win. What if the election ends up including two liberal candidates and one conservative? It is possible that the liberal vote will split and victory will go to the minority party. In this case, the outcome does not reflect the majority’s preference.
Does the majority view prevail in the case of sugar quotas? Clearly there are more sugar consumers in the United States than sugar producers, but the U.S. domestic sugar lobby (www.sugarcane.org) has successfully argued for protection against imports since 1789. By law, therefore, U.S. cookie and candy makers must use 85% domestic sugar in their products. Meanwhile quotas on imported sugar restrict supply and keep the domestic sugar price up—raising prices for companies that use sugar in producing their goods and for consumers. The European Union allows sugar imports, and prices there are 40% lower than U.S. sugar prices. Sugar-producing countries in the Caribbean repeatedly protest the U.S. quotas at the World Trade Organization meetings, but each bite of cookie, at present, costs you more than if there were no sugar lobby. This case goes against the theory of the “median” voter in a democracy. The median voter theory argues that politicians will try to match policies to what pleases the median voter preferences. If we think of political positions along a spectrum from left to right, the median voter is in the middle of the spectrum. This theory argues that actual policy will reflect “middle of the road.” In the case of sugar lobby politics, the minority, not the median, dominates policy.
Sometimes it is not even clear how to define the majority opinion. Step aside from politics for a moment and think about a choice facing three families (the Ortegas, the Schmidts, and the Alexanders) who are planning to celebrate New Year’s Day together. They agree to vote on the menu, choosing from three entrees, and they agree that the majority vote wins. With three families, it seems reasonable that one producing choice will get a 2–1 majority. What if, however, their vote ends up looking like ?
Clearly, the three families disagree on their first choice. However, the problem goes even deeper. Instead of looking at all three choices at once, compare them two at a time. (See ) In a vote of turkey versus beef, turkey wins by 2–1. In a vote of beef versus lasagna, beef wins 2–1. If turkey beats beef, and beef beats lasagna, then it might seem only logical that turkey must also beat lasagna. However, with the preferences, lasagna is preferred to turkey by a 2–1 vote, as well. If lasagna is preferred to turkey, and turkey beats beef, then surely it must be that lasagna also beats beef? Actually, no. Beef beats lasagna. In other words, the majority view may not win. Clearly, as any car salesperson will tell you, the way one presents choices to us influences our decisions. 
We call the situation in which Choice A is preferred by a majority over Choice B, Choice B is preferred by a majority over Choice C, and Choice C is preferred by a majority over Choice A a voting cycle. It is easy to imagine sets of government choices—say, perhaps the choice between increased defense spending, increased government spending on health care, and a tax cut—in which a voting cycle could occur. The result will be determined by the order in which interested parties present and vote on choices, not by majority rule, because every choice is both preferred to some alternative and also not preferred to another alternative.

### Where Is Government’s Self-Correcting Mechanism?

When a firm produces a product no one wants to buy or produces at a higher cost than its competitors, the firm is likely to suffer losses. If it cannot change its ways, it will go out of business. This self-correcting mechanism in the marketplace can have harsh effects on workers or on local economies, but it also puts pressure on firms for good performance.
Government agencies, however, do not sell their products in a market. They receive tax dollars instead. They are not challenged by competitors as are private-sector firms. If the U.S. Department of Education or the U.S. Department of Defense is performing poorly, citizens cannot purchase their services from another provider and drive the existing government agencies into bankruptcy. If you are upset that the Internal Revenue Service is slow in sending you a tax refund or seems unable to answer your questions, you cannot decide to pay your income taxes through a different organization. Of course, elected politicians can assign new leaders to government agencies and instruct them to reorganize or to emphasize a different mission. The pressure government faces, however, to change its bureaucracy, to seek greater efficiency, and to improve customer responsiveness is much milder than the threat of being put out of business altogether.
This insight suggests that when government provides goods or services directly, we might expect it to do so with less efficiency than private firms—except in certain cases where the government agency may compete directly with private firms. At the local level, for example, government can provide directly services like garbage collection, using private firms under contract to the government, or by a mix of government employees competing with private firms.

### A Balanced View of Markets and Government

The British statesman Sir Winston Churchill (1874–1965) once wrote: “No one pretends that democracy is perfect or all-wise. Indeed, it has been said that democracy is the worst form of government except for all of the other forms which have been tried from time to time.” In that spirit, the theme of this discussion is certainly not that we should abandon democratic government. A practical student of public policy needs to recognize that in some cases, like the case of well-organized special interests or pork-barrel legislation, a democratic government may seek to enact economically unwise projects or programs. In other cases, by placing a low priority on the problems of those who are not well organized or who are less likely to vote, the government may fail to act when it could do some good. In these and other cases, there is no automatic reason to believe that government will necessarily make economically sensible choices.
 “The true test of a first-rate mind is the ability to hold two contradictory ideas at the same time,” wrote the American author F. Scott Fitzgerald (1896–1940). At this point in your study of microeconomics, you should be able to go one better than Fitzgerald and hold three somewhat contradictory ideas about the interrelationship between markets and government in your mind at the same time.
First, markets are extraordinarily useful and flexible institutions through which society can allocate its scarce resources. We introduced this idea with the subjects of international trade and demand and supply in other chapters and reinforced it in all the subsequent discussions of how households and firms make decisions.
Second, markets may sometimes produce unwanted results. A short list of the cases in which markets produce unwanted results includes monopoly and other cases of imperfect competition, pollution, poverty and inequality of incomes, discrimination, and failure to provide insurance.
Third, while government may play a useful role in addressing the problems of markets, government action is also imperfect and may not reflect majority views. Economists readily admit that, in settings like monopoly or negative externalities, a potential role exists for government intervention. However, in the real world, it is not enough to point out that government action might be a good idea. Instead, we must have some confidence that the government is likely to identify and carry out the appropriate public policy. To make sensible judgments about economic policy, we must see the strengths and weaknesses of both markets and government. We must not idealize or demonize either unregulated markets or government actions. Instead, consider the actual strengths and weaknesses of real-world markets and real-world governments.
These three insights seldom lead to simple or obvious political conclusions. As the famous British economist Joan Robinson wrote some decades ago: “[E]conomic theory, in itself, preaches no doctrines and cannot establish any universally valid laws. It is a method of ordering ideas and formulating questions.” The study of economics is neither politically conservative, nor moderate, nor liberal. There are economists who are Democrats, Republicans, libertarians, socialists, and members of every other political group you can name. Of course, conservatives may tend to emphasize the virtues of markets and the limitations of government, while liberals may tend to emphasize the shortcomings of markets and the need for government programs. Such differences only illustrate that the language and terminology of economics is not limited to one set of political beliefs, but can be used by all.

### Key Concepts and Summary

Majority votes can run into difficulties when more than two choices exist. A voting cycle occurs when, in a situation with at least three choices, choice A is preferred by a majority vote to choice B, choice B is preferred by a majority vote to choice C, and choice C is preferred by a majority vote to choice A. In such a situation, it is impossible to identify what the majority prefers. Another difficulty arises when the vote is so divided that no choice receives a majority.
A practical approach to microeconomic policy will need to take a realistic view of the specific strengths and weaknesses of markets as well as government, rather than making the easy but wrong assumption that either the market or government is always beneficial or always harmful.
