The Coming Slump

Zero Hedge

Submitted by Alasdair Macleod via The Cobden Centre blog,

Governments and central banks have made little or no progress in recovering from the Lehman crisis six years ago. The problem is not helped by dependence on statistics which are downright misleading. This is particularly true of real GDP, comprised of nominal GDP deflated by an estimate of price inflation. First, we must discuss the inflation adjustment.

The idea that there is such a thing as a valid measure of price inflation is only true in an econometrician’s imagination. An index which might be theoretically valid at a single point in time is only subsequently valid in the wholly artificial construction of an unchanging, or “evenly rotating economy”: in other words an economy where everyone who is employed remains in the same employment producing at the same rate, retains the same proportion of cash liquidity, and buys exactly the same things in the same quantities. Furthermore business inventory quantities must also be static. All human choice must be excluded for this condition. Only then can any differences in prices be identified as due to changes in the quantity of money and credit. Besides this fiction, an accurate index cannot then be constructed, because not every economic transaction is reported. 

Furthermore biases are built into the index, for example to overweight consumer spending relative to capital investment, and to incorporate government activity which is provided to users free of cost or subsidised. Buying art, stockmarket investments or a house are as much economic transactions as buying a loaf of bread, but these activities and many like them are specifically excluded. Worse still, adjustments are often made to conceal price increases in index constituents under one pretext or another.

Economic activities are also only selectively included in GDP, which is supposed to be the total of a country’s transactions over a period of time expressed as a money total. A perfect GDP number would include all economic transactions, and in this case would capture the changes in consumer preferences excluded from a static price index. But there is no way of identifying them to tell the difference between changes due to economic progress and changes due to monetary inflation.

To illustrate this point further, let’s assume that in a nation’s economy there is no change in the quantity of money earned, held in cash, borrowed or repaid between two dates. This being the case, what will be the change in GDP? The answer is obviously zero. People can make and buy different products and offer and pay for different services at different prices, but if the total amount of money spent is unchanged there can be no change in GDP. Instead of measuring economic growth, a meaningless term, it only measures the quantity of money spent. To summarise so far, governments are using a price index, for which there is no sound theoretical basis, to deflate a money quantity mistakenly believed to represent economic progress. In our haste to dispense with the reality of markets we have substituted half-baked ideas utilising dodgy numbers. The error goes wholly unrecognised by the majority of economists, market commentators and of course the political classes.

It also explains some of the disconnection between monetary and price inflation. Price inflation in this context refers to the increase in prices due to demand enabled by extra money and credit. As already stated, newly issued money today is spent on assets and financial speculation, excluded from both GDP and its deflator.
