Richard Wagner’s latest book is not about James M. Buchanan. At least not in the way you’d expect given the title: James M. Buchanan and Liberal Political Economy: A Rational Reconstruction. Wagner has written elsewhere that economics is a discipline that “deals with thoughts, not with things,”[i] and he has stayed true to that approach here, writing an intellectual biography that is about Buchanan’s ideas first and his work and person second. The result is a masterful work that invites both the experienced and the novice student of political economy to think about democracy, self-governance, and constitutional processes in new ways.
A rational reconstruction of a rich scholarly life like Buchanan’s is no simple task. The biographical pieces are the easy part. The hard part is absorbing a lifetime of scholarship by Buchanan — a heavy-hitting, extra pot of coffee, sleep-is-for-the-weak kind of lifetime — and then transforming that lifetime of scholarship into a neat 300-page presentation that delicately arranges all those decades of coffee and mimeographs into a cohesive theoretical frame. When the Scandinavian Journal of Economics printed Buchanan’s list of publications at the time of his Nobel award, the list included 23 books, 14 monographs, and an 18-page long list of articles, book chapters, and comments.[ii] That was only two-thirds of the way through his career. In short, Buchanan wrote a lot. This commitment to his craft shines through particularly in the appendix to James M. Buchanan and Liberal Political Economy and in my interview with Wagner, where he offers a set of more personal reflections on working with Buchanan than appear in the rest of the book.
Further, Buchanan’s body of work is not just long, but deep. He is credited as the originator of not one, but two established fields within economics: public choice and constitutional political economy. Both of these fields remain important within the discipline of economics and in other parts of the social sciences today, making the impact of Buchanan’s theorizing difficult to fully grasp. His co-authored book with Gordon Tullock, The Calculus of Consent: Logical Foundations of Constitutional Democracy, would surely alone have made any shortlist of the 20th century’s most influential works in political economy.[iii] And that really was just the beginning. Not too shabby for a country boy who went to Middle Tennessee State College for undergrad because he couldn’t afford the University of Tennessee.[iv]
Wagner argues persuasively that the epicenter of Buchanan’s contributions to public choice and constitutional political economy is a humbly titled article published in 1949 in the Journal of Political Economy, “The Pure Theory of Government Finance: A Suggested Approach.”[v] In brief, the suggestion offered by Buchanan in that article is that theorizing about governments as if they are single-minded, organism-like abstractions with unified visions and plans is deeply flawed. Instead, governments are collections of individuals, each of whom have their own separate goals and plans, and who will often be in conflict with each other. Stated so plainly it seems obvious, as obvious as the existence of gravity or the fact that the earth revolves around the sun. The obvious does not always make it in to theory without a fight though, and Buchanan worked on developing this individualistic approach to understanding political organization for the rest of his life.
Another way of thinking about Buchanan’s individualistic approach to public finance is that it is at heart a re-conceptualization of public finance as a democratic project. In contrast, the dominant approach to public finance economics in the 1940s and 1950s, with its emphasis on the identification of optimal strategies without concern for how that information would be revealed and how the resulting plans would be executed, was designed for a world of benevolent despots and obedient subjects. In Buchanan’s view, that kind of theorizing might have relevance for the study of feudal or monarchic societies, but simply wouldn’t be of use in seeking to understand democracies. The individual’s active role as a democratic citizen in the political project is simply too important to be ignored. This focus on the individual’s active role in constructing their environment would continue through to Buchanan’s 1979 essay, “Natural and Artifactual Man,” in which he explores the individual’s constitution of themselves and their own wants, projects, and plans, as an exercise in self-governance.[vi] This consistent concern with democracy and the individual’s role in the process of self-governance connected Buchanan’s theorizing to that of other figures identified by Wagner as integral to establishing the foundation for what would become public choice economics, such as Knut Wicksell, Frank Knight, Vincent Ostrom, and Italian public finance theorists including Attilio da Empoli, Maffeo Pantaleoni, Vilfredo Pareto, and Luigi Einaudi.[vii]
The metaphor that Wagner suggests for thinking about Buchanan’s career as a whole is that of an oak tree, deeply rooted in his 1949 article on public finance and then branching out from that single seed.[viii] In Chapter 3, Wagner explains Buchanan’s constitutional framework, in which he studied how and for what purpose individuals might choose to bind themselves through the creation of rules, as emerging from this individualistic, democratic approach. Chapter 4 explores the extension of this constitutional approach into the study of political externalities, federalism, and competitive government. Chapter 5 discusses the way in which Buchanan incorporated notions of time into this theorizing, particularly through the study of public debt, a project in which Wagner himself was an important partner, for example, their 1977 book, Democracy in Deficit.[ix] Chapters 6 and 7 address the themes of ethics, liberty, and individual responsibility, with a particular focus on the way that these were integral to Buchanan’s theorizing throughout his life and represented important contributions to positive as well as normative projects within political economy.
This book and my interview with Wagner both demonstrate that the creation of a rational reconstruction is active, not passive. In the process of revealing the superstructure within Buchanan’s body of work, Wagner reveals something about himself and his own approach to the study of the social world as well. His career, including studying with Buchanan at the University of Virginia and working alongside Buchanan as a faculty member at George Mason University, has given him unparalleled insight into Buchanan’s democratic approach to public finance. This is an approach that he has advanced and re-imagined in many ways over the course of his own illustrious career. This active advancement has been most recently realized not only through this current book, but also through Wagner’s ongoing work on entangled political economy and macroeconomic phenomena as the result of emergent, individualistic processes.[x]
So perhaps the oak tree metaphor needs to be modified somewhat, or at least the idea that it grew for 64 years. Instead, the study of democratic public finance continues to grow today, through the work of Wagner and others who have sought to extend Buchanan’s research program. So long as research in public choice and constitutional political economy continues to generate meaningful insights into the social world, there will be plenty of sun, soil, and sky for the tree Buchanan planted in 1949 to continue to grow.
