- Economics is a vital source of ideas for understanding how the world works. Although the greatest teachers of economics have always stressed this, economics as it is currently taught often deemphasizes the study of real-world problems and dwells too much on nonessentials. Economics teachers would find greater success (i.e., their students would retain more knowledge) if they focused more on the core lessons of economics, such as how the price system coordinates and harmonizes the decision-making of countless individuals, and why the resulting patterns of spontaneous order are self-regulating but can fall prey to public policies that create undesirable, unintended consequences.
- Although Adam Smith didnt originate economics, his synthesizing treatise The Wealth of Nations is a towering achievement in the intellectual history of Western Civilization. If one mark of a giant of economics is that his works continue to serve as sources of insight and debate for later generations, then Smith is surely among the tallest giants in the field. Along with instilling basic economic principles and their practical applications, economics teachers should strive to cultivate an appreciation for great political economists, from Smith and David Hume to F. A. Hayek and James Buchanan.
- The tradition of engaging the public on issues of practical importance while adhering to basic economic truths is a legacy that was carried forth by leaders of the Austrian school of economics. Carl Menger, Eugene Bohm-Bawerk, Ludwig von Mises, F. A. Hayek, and their intellectual progenyall relied on basic economic principles to develop their profound insights on Big Picture issues, such as the workings of a free-market price system, capitalism versus socialism, competition and entrepreneurship, and inflation and unemployment. Their theoretical works were almost always geared toward shedding light on real-world problems: they didnt view abstract theorizing as an end in itself.
- Although economics has become increasingly theoretical (one is tempted to say merely theoretical), alternative approaches that apply economic principles to pressing public issues have also gathered steam. James Buchanan, Gordon Tullock, Vincent and Elinor Ostrom, Ronald Coase, and the late Warren Samuels, for example, have used economic reasoning and analysis to vastly enrich our understanding of political decision-making, civil society, property rights, and the legal system. By putting the political back into political economy (the common name for the discipline in its early days, when it focused more on public issues), these thinkers demonstrate an affinity for that older tradition.
- If economics is to fulfill its potential as a vital tool for understanding and improving the world, the economic mainstream must turn its attention to the puzzles and problems that captivate the public. And then it must communicate its findings effectively to policymakers, opinion leaders, and society at large. If the economics profession continues to indulge its obsession with building abstract models that are based on unrealistic assumptions and devoid of empirical content, the public will regard it as irrelevant and will seek counsel from those who are not skilled inand who may be hostile tothe economic way of thinking.
Economics suffers from a bad reputation as a dismal science plagued with lifeless graphs and dry statistics. In reality, this accusation has less to do with substance than with style; the subject itself is lively and vital. Economics provides a powerful framework for understanding what goes on in the marketplace, the voting booth, the family, the community, and every other sphere of social activity; indeed, the application (or misapplication) of its principles shapes the fate of nations. The greatest teachers of economicsfrom before Adam Smith on down to the presenthave always impressed upon the public their disciplines explanatory powers and importance for human well-being.
In Living Economics: Yesterday, Today, and Tomorrow, Peter J. Boettke contributes to this tradition by discussing the ideas of some of the most important economists of the past centuryfamous and not so famous worldly philosophers whose innovative theories shed light on pressing issues such as inflation and unemployment, capitalism and socialism, competition and entrepreneurship, law and politics, and customs and civil society. He also explains how the conduct of economists, both in classrooms and in scholarly journals written for their peers, enhances or diminishes the influence of economic thinking on the world of practical affairs.
Boettkes thorough diagnosis of the maladies of todays economics profession is especially valuable. He concludes by urging his colleagues to return to their disciplines original mission: to make sense of human action and communicate the findings to a public sorely in need of cogent counsel. Scholarly and yet highly accessible, Living Economics enables readers to see far across the human landscape by standing on the shoulders of giants in the economics profession, as Boettke and his occasional chapter co-authorsChristopher Coyne, Steve Horwitz, Peter Leeson, David L. Prychitko, and Frederic Sauteteagerly acknowledge. Its sparkling insights make it worthwhile reading for economics teachers, students, and anyone interested in exploring the frontiers of the economic way of thinking and their potential impact on the world.
Part I examines the aim and methods of economic education. F. A. Hayek said that the task of economics was to teach people how little they knew about what they imagined they could design. He and other great economists, from Adam Smith to James Buchanan, have emphasized the unplanned or spontaneous aspects of the private-property market economy, especially self-regulation via the adjustment of relative prices and the profit and loss calculus. This may seem like simple economics, but it is not simple-minded economics.
Making this the theme of principles courses would be immensely helpful for teaching students core concepts such as thinking on the margin; opportunity cost; the gains from specialization, trade, and innovation; and the requirements of wealth creation. It would be vastly superior to teaching a watered-down version of Ph.D. classes or emphasizing market failure as if that were the essential characteristic of a market economy. Even at higher levels of economic study, spontaneous order is an invaluable unifying conceptone that suggests rewarding approaches to numerous research topics for the graduate student pursuing an academic career. This is one of many suggestions that Boettke has for grad students.
Teachers of Economics
Part II, the heart of the book, examines the teachings of more than a dozen economists who exemplify excellence. Boettke begins with Hans Sennholz, his undergraduate professor at Grove City College, whose public engagement on topical issues such as inflation, unemployment, and monetary reform was animated by a passionate advocacy of a free society. To those students who were open, Sennholzs message was transformative, Boettke writes.
Like Sennholz, Murray Rothbard, another early influence on Boettke, embraced the Austrian school of economics and wrote volumes on a wide variety of theoretical, historical, and policy concerns. His unjustly overlooked writings on the Soviet economy help answer a puzzling question: If central planning is very inefficient, why didnt the Soviet economy collapse sooner? Boettke explains how he utilized Rothbards insights in his own works about the Soviet economy.
Kenneth Boulding is seldom mentioned in conjunction with Austrian economicsone reason is that he was a veritable school unto himselfbut he shared the radical subjectivism of the Austrians, as is evident throughout the nearly 40 books and hundreds of articles he wrote on topics as diverse as capital theory, war and peace, and social evolution. Boettke encourages young scholars to excavate the goldmine that is Bouldings theoretical corpus.
Next Boettke examines the works of economists who enlarged the domain of the profession by applying economic thinking to the political realm. The late Warren Samuels emphasized the importance of political and legal institutions in shaping economic activity. His correspondence with James M. Buchanan about a legal case involving apple growers illustrates fascinating differences in their respective approaches.
Gordon Tullock, Buchanans early co-author and co-developer of public choice theory, has used economic thinking to illuminate political phenomena such as logrolling, voter motives, and rent seeking. To do this effectively he had to overcome interesting theoretical challenges, such as the need to identify filtering signals and equilibrating processes that differ from those common to commercial transactions, Boettke explains.
Public choice analysis usually emphasizes the institutional sources of conflict in collective decision-making. In contrast, the work of Vincent and Elinor Ostrom emphasizes the roots of cooperation in the non-market arena. By shedding light on the underpinnings of civil society, they aim to cultivate citizens that have the capacity for self-governance, Boettke explains.
During his short but productive life, Don Lavoie applied his creative mind to a diverse range of topics, including central planning, the history of economic thought, and computer science. Some Austrian economists deemed his work on the philosophy of the social sciences heretical, but Boettke suggests that it fits squarely within their tradition.
Although a sociologist rather than an economist, Peter Berger has a lot to offer the dismal science. Thomas Mayer confirms this in an economics book apparently patterned after Bergers bestseller, An Invitation to Sociology. Both works captivate the reader by explaining mysteries of everyday life that most people are content to leave unanswered, Boettke explains.
Ludwig von Mises, the unofficial dean of the Austrian school in the twentieth century, was as controversial for his stance on economic methodology as he was for his advocacy of laissez-faire. Among other heresies, he held that basic theorizing must precede empirical analysis because facts dont speak for themselves; the relevant facts must be selected and interpreted, and those steps rely on valid principles. Misess thoroughgoing defense of methodological apriorism confronts the claims of positivism but avoids the epistemological abyss of postmodernism, Boettke contends.
Mises also argued that the market isnt so much a place as it is a process, one that entails risk-taking, economizing, and constant change. His pupil Israel Kirzner has developed this idea further, arguing that the changeless general equilibrium models of neoclassical theory ignore, rather than explain, the most vital aspects of real-world markets, such as rivalrous competition and entrepreneurial discovery.
F. A. Hayek, the most famous economist to follow in Misess footsteps, is celebrated widely for his work on knowledge and social coordination, but he also wrote extensively about the political economy of freedom. These topics are not unrelated: Hayeks critique of socialism reflects his view of how markets use knowledge and create benefits far greater than anyone had intended.
James M. Buchanan shares many of Hayeks views but has taken political economy in a new direction. It can be framed as follows: Economics is about a game played within rules, but how are those rules determined? Buchanans answer dispels romantic notions about politics, but its realism has fostered a fruitful sub-discipline within public choice: constitutional political economy.
The Practice of Economics
Although the economics profession continues to shed light on the way the world works, the mainstream began to drift off course starting in the early twentieth century, Boettke argues in Part III.
Where did economics go wrong? Modern economics took flight from reality as mathematical formalism gained ascendency, especially after the publication of Paul Samuelsons Foundations of Economics (1947). Abetting this trend were the tacit assumption of man as machine and a corollary: the belief that economic prosperity was an engineering problem best dealt with by strong doses of Keynesian demand management and cost-benefit analysis, each treatment to be administered by the high priests of the Keynesian-neoclassical orthodoxy. Ironically, economics and political economy were well equipped to guard against such hubris, as Adam Smith and F. A. Hayek explained.
Fortunately, a counter-trend against what Hayek called constructive rationalism and what Smith called the man of systems is underway. An emphasis on real-world economic problems is making a comeback, and the limitations of policy activism are better understood. The timing is propitious. The fate of humanity, Boettke writes, will turn on the ability of those within the mainline of economics to beat back economic ignorance, special interest politics, and the hubristic ambitions of the man of systems.
