The Long Run


Niall Ferguson’s misunderstanding of Keynes led me to the question of how humans should balance the present against the long run?

It’s hard for us primates to have a real clue about the long run — the chain of events that may occur, the kind of world that will form. In the long run — the billions of years for which Earth has existed — modern human civilisation is a flash, a momentary pulsation of order imposed by primates on the face of the Earth — modern cities, roads, ports, oil wells, telecommunications and so forth built up over a little more than a century, a little more than two or three frail human lifespans.

Human projections of the direction of the future are notoriously unreliable. Professional futurists who devote careers to mapping the trajectory of human and earthly progress are often far wide of the mark. And in the realm of markets and economics, human projectional abilities are notoriously awful — only 0.4% of money managers beat the market over ten years.

As humans, our only window to the future is our imaginations. We cannot know the future, but we can imagine it as Ludwig Lachmann once noted. And in a world where everyone is working from unique internal models and expectations — for a very general example, Keynesians expecting zero rates and deflation, Austrians expecting rising rates and inflation — divergent human imaginations and expectations is an ingredient for chaos that renders assumptions of equilibrium hopelessly idealistic.

A tiny minority of fundamental investors can beat the market — Keynes himself trounced the market between 1926 and 1946, for example by following principles of value investing (like Benjamin Graham later advocated). But like in poker, while virtually everyone at the table believes they can beat the game in the long run — through, perhaps, virtues of good judgement, or good luck, or some combination of the two — the historical record shows that the vast majority of predictors are chumps. And for what it’s worth, markets are a harder game to win than games like poker. In poker, precise probabilities can be assigned to outcomes — there are no unknown unknowns in a deck of playing cards. In the market — and other fields of complex, messy human action — we cannot assign precise probabilities to anything. We are left with pure Bayesianism, with probabilities merely reflecting subjective human judgments about the future. And in valuing assets, as Keynes noted we are not even searching for the prettiest face, but for a prediction of what the market will deem to be the prettiest face.

This means that long run fears whether held by an individual or a minority or a majority are but ethereal whispers on the wind, far-fetched possibilities. It means that present crises like mass unemployment have a crushing weight of importance that potential imagined future crises do not have, and can never have until they are upon us. As the fighters of potential future demons — or in the European case, self-imposed present demons — suffer from high unemployment and weak growth in the present (which in turn create other problems — deterioration of skills, mass social and political disillusionment, etc) this becomes more and more dazzlingly apparent.

But in the long run, the historical record shows that crises certainly happen, even if they are not the ones that we might initially imagine (although they are very often something that someone imagined, however obscure). Human history is pockmarked by material crises — unemployment, displacement, failed crops, drought, marauders and vagabonds, volcanism, feudalism, slavery, invasion, a thousand terrors that might snuff out life, snuff out our unbroken genetic line back into the depths antiquity, prehistory and the saga of human and prehuman evolution. While we cannot predict the future, we can prepare and robustify during the boom so that we might have sufficient resources to deal with a crisis in the slump. Traditionally, this meant storing crops in granaries during good harvests to offset the potential damage by future famines and saving money in times of economic plenty to disburse when the economy turned downward.  In the modern context of globalisation and long, snaking supply chains it might also mean bolstering energy independence by developing wind and solar and nuclear energy resources as a decentralised replacement to fossil fuels. It might mean the decentralisation of production through widespread molecular manufacturing and disassembly technologies. In the most literal and brutal sense — that of human extinction — it might mean colonising space to spread and diversify the human genome throughout the cosmos.

Ultimately, we prepare for an uncertain future by acting in the present. The long run begins now, and now is all we have.


What Are Interest Rates And Can They Be Artificially Low Or High?

Many economic commentators believe that interest rates in America and around the world are “artificially low”. Indeed, I too have used the term in the past to refer to the condition in Europe that saw interest rates across the member states converge to a uniformly low level at the introduction of the Euro, only to diverge and soar in the periphery during the ongoing crisis.

So what is an interest rate? An interest rate is the cost of money now. As Eugen von Böhm-Bawerk noted, interest rates result from people valuing money in the present more highly than money in the future. If a business is starting out, and has insufficient capital to carry out its plans it will seek investment, either through selling equity in the ownership of the business, or through credit from lenders. For a lender, an interest rate is their profit for giving up the spending power of their capital to another who desires it now, attached to the risk that the borrower will default.

In monetary economies, money tends to be distributed relatively scarcely. In a commodity-based monetary system, the level of scarcity is determined by the physical limits of how much of a commodity can be pulled out of the ground. In a fiat-based monetary system, there is no such natural scarcity, but money’s relative scarcity is controlled by the banking system and central bank that lends it into the economy. If money was distributed infinitely widely and freely, there would be no such thing as an interest rate as there would be no cost to obtaining money now, just as there is no cost to obtaining a widely-distributed and freely-available commodity like air (at least on the face of the Earth!). Without scarcity money would lose its usability as a currency, as there is no incentive to trade for a substance which is uniformly and effectively infinitely available to everyone. So an interest rate is not only the cost of money, but also a symptom of its scarcity (and, as Keynes pointed out, a key mechanism through which rentiers profit).

So, where does the idea that interest rates can be made artificially low or artificially high arise from?

The notion of an artificially low or high interest rate implies the existence of a natural interest rate, from which the market rate diverges. It is a widely-held notion, and indeed, Ron Paul made reference to the notion of a natural rate of interest in his debate with Paul Krugman last year. A widely-used definition of the “natural rate of interest” appears in Wicksell (1898):

There is a certain rate of interest on loans which is neutral in respect to commodity prices, and tends neither to raise nor to lower them.

This is easy to define and hard to calculate. It is whatever interest rate yields a zero-percent inflationary level. Because interest rates have a nonlinear relationship with inflation, it is difficult to say precisely what the natural interest rate is at any given time, but Wicksell’s definition specifies that a positive inflation rate means the market rate is above the natural rate, and a negative inflation rate means the market is below the natural rate. (Interestingly, it should be noted that the historical Federal Funds Rate comes pretty close to loosely approximating the historical difference between 0 and the CPI rate, despite questions of whether the CPI really reflects the true price level due to not including housing and equity markets which often record much greater gains or greater losses than consumer prices).

The notion of a natural rate of interest is interesting and helpful — certainly, high levels of inflation can be challenged through decreasing interest rates (or more generally increasing credit-availability), and deflation can be challenged by decreasing interest rates (or more generally increasing credit availability). If the goal of monetary policy is price stability, then the notion of a “natural interest rate” as a guide for monetary policy is useful.

But policies of macrostabilisation have been strongly questioned by the work of Hyman Minsky, which posited the idea that stability is itself destabilising, because it leads to overconfidence which itself results in malinvestment and credit and price bubbles.

Austrian Business Cycle Theory (ABCT) developed by Ludwig von Mises and Friedrich Hayek, most influentially in Mises’ 1912 work The Theory of Money and Credit, theorises that the business cycle is caused by credit expansion (often fuelled by excessively low interest rates) which pours into unsustainable projects. The end of this credit expansion (as a result of a collapse resulting from excessive leverage, or from the failure of unsustainable projects, or from general overproduction, or for some other reason) results in a panic and bust. According to ABCT, the underlying issue is that the banking system made money cheaply available, and the market rate of interest falls beneath the natural rate of interest, manifesting as price inflation.

I do not dispute the idea that bubbles tend to coincide with credit expansion and easy lending. But it is tough to say whether credit expansion is a consequence or a cause of the bubble. What is the necessary precursor of an unsustainable credit expansion? Overconfidence, and the idea that prices will just keep going up when sooner or later the credit expansion will run out steam. This could be the overconfidence of central bankers, who believe that macrostabilisation policies have produced a “Great Moderation”, or the overconfidence of traders who hope to get rich quick, or the overconfidence of homeowners who see rising home prices as an easy opportunity to remortgage and consume more, or the overconfidence of private banks who hope to make bumper gains on loans or loan-related securities (Carl Menger noted that fractional reserve banking and credit-fuelled bubbles originated in economies with no central bank, in contradiction of those ABCT-advocates who go so far as to say that without central banking there would be no business cycle at all).

And is price stability really “natural”? Wicksell (and other advocates of a “natural rate of interest” like RBCT and certain Austrians) seem to imply so. But why should it be the norm that prices are stable? In competitive markets — like modern day high-tech markets — the tendency may be toward deflation rather than stability, as improving technology lowers manufacturing costs, and firms lower prices to stay competitive with each other. Or in markets for scarce goods — like commodities of which there exists a limited quantity — the tendency may be toward inflation, as producers may have to spend more to extract difficult-to-extract resources form the ground. Ultimately, human action in market activity is unpredictable and determined by the subjective preferences of all market participants, and this applies as much to the market for money as it does for any market. There is no reason to believe that prices tend toward stability, and the empirical record shows a significant level of variation in price levels under both the gold standard and the modern fiat system.

Ultimately, if interest rates are the cost of money, and in a fiat monetary system the quantity and availability of money is determined by lending institutions and the central bank, how can any interest rate not be artificial (i.e. an expression of the subjective opinions, forecasts and plans of those involved in determining the availability of credit and money including governments and central bankers)? Even under a commodity-money system, the availability of money is still determined by the lending system, as well as the miners who pull the monetary commodity or commodities out of the ground (and any legal tender laws that define money, for example monetising gold and demonetising silver).

And if all interest rates in contemporary markets are to some degree artificial this raises some difficult questions, because it means that the availability of capital, and thus the profitability (or unprofitability) of rentiers are effectively policy choices of the state (or the central bank).
