What does Don Lavoie tell us about the implications of the knowledge problem for the plans of political entrepreneurs?

One of the questions that I have been contemplating in recent months is whether the tariff policies of President Trump could be part of a coherent economic plan. Can his policies be rationalized in terms of revenue raising objectives, the optimum tariff argument, provision of appropriate incentives to manufacturing industries to meet defence or employment objectives, or the pursuit of foreign policy objectives? Is it possible that he is assigning policy instruments to objectives in a manner consistent with a rational plan?

The presumption underlying such questions is that it is preferable for political entrepreneurs to endeavor to ensure that their economic plans are coherent rather than unprincipled, unpredictable, and capricious. Although that may be a reasonable presumption, there is another other option that should be considered. Perhaps it is appropriate for political entrepreneurs to refrain from engaging in economic planning.

I was reminded of that while reading Don Lavoie’s book, National Economic Planning: What is Left?  Don Lavoie was an economics professor at George Mason University, where he taught from 1981 until his death in 2001. This book was originally published by the Cato Institute in 1985 and was reprinted by the Mercatus Center in 2016.

In this book Don Lavoie explains, among other things, that political entrepreneurs are confronted with a fundamental knowledge problem when they seek to plan economic activities, The epigraph quoted above (from page 181) encapsulates an important implication of the knowledge problem.

Lavoie’s explanation of the information problem begins with the insights of F. A. Hayek. The data that a planning agency would require to engage in rational economic planning resides in the separate minds of millions of people. The data exists only in a dispersed form that cannot be fully extracted by any single agent in society. The only way that knowledge can be used effectively is by relying on competitive struggles in a market system.  (p. 56)

The most obvious implication is that it is impossible for markets to be replaced by comprehensive economic planning. However, more modest attempts to steer the market towards particular outcomes also obstruct the source of knowledge which is essential to rational decision-making. (p. 56-7)

Lavoie points out that the only way we can know whether we are squandering resources by over- or underinvesting in microprocessors or steel, for example, is via “the messages contained in the relative profitability of rival firms in these industries”. He adds:

“But this is precisely the information we garble when we channel money toward one or another of the contenders. Deprived of its elimination process, the market would no longer be able to serve its function as a method for discovering better and eliminating worse production techniques. Without the necessity of responding to consumers’ wants or needs, businesses would never withdraw from unprofitable avenues of production.” (p.181)

Lavoie notes that advocates of industry policy disagree on the directions in which the market should be steered. For example, Felix Rohatyn wanted to funnel aid to sunset industries while Robert Reich wanted to funnel it to sunrise industries. He sums up:

“It is the main conclusion of the argument that I have called the knowledge problem … that there are no rational grounds on which Reich could ever convince Rohatyn or vice versa on such matters as are involved in economic change. As a result, such battles are sure to be fought with weapons other than carefully reasoned argument.” (p. 200-201)

Lavoie notes that Rohatyn and Reich both argued that it is the responsibility of a strong leader to coordinate the actions of the rest of us. (p.190) The coordination they had in mind seems to be more akin to the coordination that military leaders impose by giving orders to subordinates than the coordination among individuals that occurs voluntarily and spontaneously in a free market.

Lavoie argues that economic planning is inherently militaristic: “The practice of planning is nothing but the militarization of the economy”. In making that point he notes that the theory of economic planning was from its inception modeled after feudalistic and militaristic organizations. (p. 230)

Some would argue that a degree of militarization is a price worth paying, or even desirable, to achieve a range of national objectives. Indeed, the conventional theory of democracy seems to entail top-down direction. Prior to elections, political leaders tell voters about their plans for education, health, social security etc. and are expected to implement those plans after they are elected.  

I am not aware of anything that Lavoie wrote that discusses the legitimacy of the concept of national objectives and the question of whether planning (and militarization) may be necessary in the pursuit of social objectives. However, he provided a highly relevant discussion of the concept of democracy in a book chapter entitled, ‘Democracy, Markets, and the Legal Order: Notes on the Nature of Politics in a Radically Liberal Society’. (The book is: Ellen Frankel Paul, Fred D. Miller, Jr., and Jeffrey Paul (Eds.) Liberalism and the Economic Order, Cambridge University Press, 1993.)

In that chapter Lavoie notes that Western liberals tend to view democracy and markets “as in some sort of necessary tension with one another”. We tend to think that “taking democracy too far undermines markets and that taking markets too far undermines democracy”. He attributes that view to “liberalism’s gradual drift into compromises with conservatism and socialism”.

Lavoie argues that liberalism needs to reinterpret its notions of markets and democracy so that they are seen to be essentially complementary. Our economics needs to take account of the cultural underpinnings of markets and our politics “needs to move beyond the model of the exercise of some kind of unified, conscious democratic will and understand democratic processes as distributed throughout the political culture”. The force of public opinion is best perceived as the distributed influence of political discourses throughout society rather than as “a concentrated will”.

Lavoie suggests that what we should mean by democracy is a distinctive kind of openness in society rather than a theory about how to elect the personnel of government:

“Democracy is not a quality of the conscious will of a representative organization that has been legitimated by the public, but a quality of the discursive process of the distributed wills of the public itself.” (p.111).

It seems to me that those who see merit in Lavoie’s view of democracy have good reasons to be skeptical about the worth of top-down planning to achieve national objectives. Individuals have different priorities and objectives that deserve to be recognized. National plans cannot solve the knowledge problem entailed in giving appropriate recognition to individual differences.
