The great majority of the many comments, speeches, articles, and books that Buchanan wrote over the course of his long scholarly career is an outgrowth of the fundamental insights that he offered in 1949.
Most foundational among these 1949 insights is this: because neither the state nor society is a singular and sentient creature, a great deal of analytical and policy confusion is spawned by treating them as such. Collections of individuals cannot be fused or aggregated together into a super-individual about whom economists and political philosophers can usefully theorize in the same ways that they theorize about actual flesh-and-blood individuals. Two or more people might share a common interest and they might—indeed, often do—join forces to pursue that common interest. But two or more people are never akin to a single sentient individual. A collection of individuals, as such, has no preferences of the sort that are had by an actual individual. A collection of individuals, as such, experiences no gains or pains; it reaps no benefits and incurs no costs. A collection of individuals, as such, makes no choices.
Until John Maynard Keynes published his General Theory of Employment, Interest, and Money in 1936, most economists—from Adam Smith in the mid-eighteenth century through economists in the early twentieth century—understood that the costs of government projects funded with debt are passed on to the future generations who, as citizen-taxpayers, must repay the debt. This understanding was rejected by the new orthodoxy and replaced with the insistence that projects funded with borrowed money are, just like projects funded with currently collected taxes, paid for at the time the projects are undertaken.
Economists often depict government as an omniscient organization that implements policies to maximize social welfare. But this depiction falls short in at least two ways. First, there is no such thing as “social welfare” beyond the welfare of each of the individuals who make up the society. Second, recognizing that government is not omniscient, there is no way for policy makers to know what policies would benefit those who are affected by them beyond discovering the preferences of its citizens as revealed by those citizens themselves.
When someone makes a choice, that person incurs a cost in the form of the value, to him or her, of what he or she forgoes as a result of making that choice. Someone who spends $15 to go to a theater to watch a movie forgoes the opportunity to spend that $15 to go to a restaurant to have lunch. Costs are often summarized in monetary terms, which obscures the fact that the true cost is not giving up the money itself, but, rather, giving up what else could have been purchased with the money.
An externality exists when the actions of some people impose costs or convey benefits to others not involved in those actions. One common example is smoke from a factory that pollutes the air that nearby individuals breathe. The typical remedy suggested by economists is to tax the externality-generating activity, or if that is not feasible, to impose a regulation that reduces the external cost—the cost that’s imposed on third parties.
Individuals have their own goals and desires, and the purpose of economic activity is to enable them to cooperate with each other so they can further those goals. As economists depict it, individuals have “utility functions” and they make choices that enable them to maximize their utility. What this means in more common language is that individuals have their own goals, which each individual understands better than does anyone else. And the subject of economics, as Buchanan saw it, is to analyze how individuals interact for their mutual benefit in furtherance of those goals.
A major difference between the social sciences and the physical sciences is that the objects of study in the physical sciences behave exactly as prescribed by the laws of nature. The challenge in the natural sciences lies in discovering those laws. The social sciences face this same challenge—there are indeed laws of social behaviour, such as the law of demand. But in the social sciences there’s an additional challenge: Its subjects—human beings—make choices about how they will behave. Predictions in the social sciences, therefore, can never be as precise, or as replicable, as predictions in the physical sciences.
Individuals engage in market exchange because it is mutually advantageous for them to do so. They voluntarily agree to trade because all parties to each exchange view it as a way for each party to further his or her own individual interest. The most familiar kind of market exchange is the simple “two-party” exchange: you give me some fish in exchange for some of my bananas. But much exchange involves many individuals, each still seeking his or her own gain, consciously organizing together to pool their resources and efforts. Thus, individuals often work together through collective organizations to carry out those mutually advantageous activities. Some organizations, such as clubs and firms, are voluntary, but other kinds of collective action are taken through government. When government is used ideally, people exchange with each other politically in order to accomplish ends that they could not accomplish individually or through market exchange.
Buchanan observed that economic analysis, for the most part, examines the choices people make subject to given rules. Constitutional economics, in contrast, examines the choice of rules themselves. Buchanan calls decisions on what those rules should be “constitutional decisions,” while decisions that people make within some set of rules are called “post-constitutional decisions.” Using a sports analogy, Buchanan likens constitutional rules to the rules of the game, and post-constitutional decisions to those that are made within the rules of the game. Constitutional decisions are the decisions that determine the rules under which the game is played.
James Buchanan devoted his presidential address to the Southern Economic Association to answering the question “What should economists do?”—also the title of his talk. To non-economists, this question probably seems silly, or at least surprising. Don’t professional economists already know what they should do? And isn’t the answer obvious—namely, study the economy?
Well, yes, of course. But what, exactly, is the economy? “The economy” is a familiar enough phrase, regularly used by economists and non-economists alike. But the very familiarity of the phrase likely inhibits those who hear it from thinking deeply about just what it refers to, and hence, about what exactly it is economists should study. Buchanan argued that economists had become seriously misled by their failure to think carefully about just what the economy is and what it does.
