Recently, the blog ThinkMarkets published a post by Gunther Schnabl about how Friedrich Hayek’s works helped to understand the link between Quantitative Easing and political unrest. The piece of writing summarized with praiseworthy precision three different stages of Friedrich Hayek’s economic and political ideas and, among the many topics it addressed, it was mentioned the increasing level of income and wealth inequality that a policy of low rates of interest might bring about.

It is well-known that Friedrich Hayek owes the Swedish School as much as he does the Austrian School on his ideas about money and capital. In fact, he borrows the distinction between natural and market interest rates from Knut Wicksell. The early writings of F.A. Hayek state that disequilibrium and crisis are caused by a market interest rate that is below the natural interest rate. There is no necessity of a Central Bank to arrive at such a situation: the credit creation of the banking system or a sudden change of the expectancies of the public could set the market interest rate well below the natural interest rate and, thus, lead to what Hayek and Nicholas Kaldor called “the Concertina Effect.”

At this point we must formulate a disclaimer: Friedrich Hayek’s theory of money and capital was so controversial and subject to so many regrets by his early supporters – like said Kaldor, Ronald Coase, or Lionel Robbins – that we can hardly carry on without reaching a previous theoretical settlement over the apportations of his works. Until then, the readings on Hayek’s economics will have mostly a heuristic and inspirational value. They will be an starting point from where to spring new insights, but hardly a single conclusive statement. Hayekian economics is a whole realm to be conquered, but precisely, the most of this quest still remains undone.

For example, if we assume – as it does the said post – that ultra-loose monetary policy enlarges inequality and engenders political instability, then we are bound to find a monetary policy that delivers, or at least does not avoid, an optimal level of inequality. As it is explained in the linked lecture, the definition of such a concept might differ whether it depends on an economic or a political or a moral perspective.

Here is where I think the works of F.A. Hayek have still so much to give to our inquiries: the matter is not where to place an optimal level of inequality, but to discover the conditions under which a certain level of inequality appears to us as legitimate, or at least tolerable. This is not a subject about quantities, but about qualities. Our mission is to discover the mechanism by which the notions of fairness, justice, or even order are formed in our beliefs.

Perhaps that is the deep meaning of the order or equilibrium that it is reach when, to use the terminology of Wicksell and Hayek’s early writings, both natural and market interest rates are the same: a state of affairs in which the most of the expectancies of the agents could prove correct. The solution does not depend upon a particular public policy, but on providing an abstract institutional structure in which each individual decision could profit the most from the spontaneous order of human interaction.
