The Shape Of 40 Years Of Inflation
I have written before that there is no single rate of inflation, and that different individuals experience their own rate dependent on their own individual spending preferences. This — among other reasons — is why I find the notion of single uniform rate of inflation — as central banks attempt to influence via their price stability mandates — problematic.
While many claim that inflation is at historic lows, those who spend a large share of their income on necessities might disagree. Inflation for those who spend a large proportion of their income on things like medical services, food, transport, clothing and energy never really went away. And that was also true during the mid 2000s — while headline inflation levels remained low, these numbers masked significant increases in necessities; certainly never to the extent of the 1970s, but not as slight as the CPI rate — pushed downward by deflation in things like consumer electronics imports from Asia — suggested.
This biflationary (or polyflationary?) reality is totally ignored by a single CPI figure. To get a true comprehension of the shape of prices, we must look at a much broader set of data:
Yet the low level of headline inflation has given central banks carte blanche to engage in quantitative easing, and various ultra-loose monetary policies like zero-interest rates — programs that tend to benefit the rich far more than anyone else. Certainly, lots of goods and services — especially things like foreign-made consumer goods and repossessed real estate — are deflating in price. But you can’t eat an iPad or a $1 burnt-out house in Detroit. Any serious discussion of monetary policy must not only consider the effects on creditors and debtors, but also the effects on those who spend a larger-than-average proportion of their income on necessities.
Another issue is that CPI leaves out both house prices as well as equity prices.
Below is CPI contrasted against equities and housing:
It is clear from this record that a central bank focused upon a price index that fails to include important factors like stock prices and house prices can easily let a housing or stocks bubble get out of hand. CPI can — as happened in both the 1990s as well as the early 2000s — remain low, while huge gains are accrued in housing and stocks. Meanwhile, central bankers can use low CPI rates as an excuse to keep interest rates low — keeping the easy money flowing into stocks and housing, and accruing even larger gains. However, because such markets are driven by leverage instead of underlying productivity, eventually the ability to accrue new debt is wiped out by debt costs, hope turns to panic, and the bubble bursts.
Both of the above examples indicate that the contemporary headline price index measures of inflation are deeply inadequate. Attempts to measure the rate of inflation that ignore data like house or stock prices will lead to flawed conclusions (rendering any such notions of “price stability” as meaningless), which has tended to lead to failed policy decisions such as those which led to the bust of 2008.
