Inflation Policy is Influenced by Historical Events
Political actions or ideologies only really acquire strength if they are accompanied by emotional involvement and, it takes significant macro events in order to get the public involved with the details of economic policy. However, when they happen, the ramifications can become deeply embedded.
In terms of inflation, consider the hyper inflation experienced by the Germans in the inter-war period. This has had a lasting cultural effect on the willingness of Germans to agree to anti-inflationary Governmental measures. Similarly, the inflationary period in the 70's has caused no end of academic spilt ink to be devoted to formulating headline inflation busting policies. Whatever it took, headline inflation had to be controlled.
Moreover, this approach can be seen in the remits of both the ECB and the Federal Reserve. Although the Federal Reserve is supposed to oversee growth and inflation, very few people argue for a focus on the former if it compromises-in the slightest- the latter.
Academic Focus on Inflation
However, the focus on inflation is not just limited to executive political decision making. Indeed, it is fascinating how this is the one area of policy that the free marketeers (Milton Friedman etc) will insist requires action. Friedman's work focused on the control of monetary aggregate growth as the key to beating inflation. Friedrich Hayek has suggested that currencies be allowed to 'compete' with one another, in order to impose an anti-inflationary discipline upon issuers. Most of the economists focusing on this area of research would advocate inflation targeting in order to keep the economy out of recession.
Inflation Induces Misallocations of Capital
However, it is to an earlier insight of Hayek's that I think attention should be focused. In 'The Pure Theory of Capital'. In this early work, Hayek attempts to explain the cyclical nature of industrial output in a systematic theory of capital. He warns of the dangers of misallocations of capital that are caused by the availability of cheap credit during the boom period. The resulting recession is lengthened by the difficulties inherent in restructuring this capital. Furthermore, this 'cheap credit' is induced by rapid relative movements in pricing.
So for example, if house prices are booming-after the dot com bust, housing, commodities and hedge funds became the new 'dot-com'-then credit issuers will be psychologically induced to issue cheap credit. I need not explain the outcome of this and how much misallocated capital was thrown at new house build in the US. Just look at this chart...
The greatest insights into how economic agents are induced into doing this is given in the behavioural finance research of Kahneman and Tversky. They demonstrate how people tend to use heuristics in order to make decisions under uncertainty and, rapidly changing prices (inflation) are a significant cause of uncertainty.
In this article, I am arguing that it is the effects of these misallocations that are the symptoms and the cause is the psychological inducements. However, you can have these misallocations-with significant effects-without having head line inflation.
Inflation without the Inflation?
As noted above, for historical reasons, the focus on fighting inflation has been on the headline numbers. However, it strikes me that recent history has highlighted the dangers of inflation without, err, the inflation! Combating head line inflation is, in my opinion, far too narrow a political course to guide. In the last few years, we have seen inflation in the risk seeking within housing, mortgage bonds, CDO's etc. All of which was watched over by the Federal Reserve.
Indeed, Greenspan spoke of a 'bond conundrum' as he had tried to raise rates only to see the markets keep market rates low. Ultimately, was this a problem to Greenspan, given that his remit is headline inflation? I suspect not, or at least, not enough to propel him to act further. Unfortunately, the inflation remit of the Federal Reserve is set up to fight yesterday's battles.
Similarly, with European Sovereign Debt, the market merrily priced in peripheral debt at close to Bund levels for most of the naughties. The Greeks never had it so good. Again, the subsequent misapplications of capital are being dealt with today. Again, the ECB's inflation busting remit does not allow it to make considerations. Bizarrely of all, the history of Communist control in China has created an environment whereby their central authorities can look at these issues in isolation.
Fighting Inflation in Future
I think a fundamental rethink in inflation targeting is needed. I do not argue for an abandonment of current head line inflation targeting however I do think that policy responses-as with Greenspan and the 'bond conundrum'-should be encumbered because of a narrow focus on inflation targeting. Indeed, Greenspan repeatedly warned of the dangers of derivative issuance. Moreover, Mervyn King has been devastatingly succinct on what he thinks about the banking system.
It's time to rethink Central Banks remits and, to stop forcing them to fight yesterday's battles.
