We need an Office for National Statistics that understands both economics and accounting

Posted on

The Financial Times noted something this morning deeply hidden within data published by the Office for National Statistics.

This unnoticed data is represented by this chart.

It shows the ratio of what is called UK gross national debt (but which is actually nothing of the sort because a significant part of the sum is always owed by the government to itself, and the rest represents deposits placed with the government not used to fund its activity) to GDP, which is the supposed measure of our national income.

This ratio is the subject of obsession among politicians, economists and financial commentators, and this chart shows that it has stabilised at a level just below 100% of GDP, a figure it had been suggested it would long ago surpass.

In fact, the data presented here is not the same as that originally published by the Office for National Statistics. As this chart, also produced by the Financial Times but based on ONS data, shows, this ratio has been subject to frequent and significant revisions over the last few years, with the revisions almost always being downward.

The result is that, despite all the claims made about the threats that national debt represents, and all the demands made for ever greater austerity cuts and what might properly be called fiscal punishment, that debt has not been out of control.

The Office for National Statistics, on the other hand, might have been out of control, and it has certainly produced a great deal of seriously misleading information that has resulted in very poor decision-making.

But the thing that the Financial Times does not note is what is most important about this. They correctly record that the figure that has been altered every time the data has been restated is not that for the supposed debt, but the figure for gross domestic product. It appears that we are hopelessly unable to get this, in itself nonsensical, figure right.

But, and this is my key point, there may be a very good reason for that.

The figure for GDP is always laden with estimates. It is riddled with assumptions. And the one thing that we know is that the assumptions used by the Office for National Statistics are cautious to the point of being absurd.

In particular, they ignore multiplier effects. When they record a great many types of expenditure, including much of that which the government undertakes, as well as investment expenditure, they fail to consider the consequences and benefits of what has happened. They believe that these sums are lost, forsaken and forgone when the reality is that they are incurred for future benefit, and, as this second chart shows, that benefit does arise and to a much greater degree than the Office for National Statistics ever thinks might be the case.

What is happening? It is that the ONS is persistently under-recording the creation of the literal stocks of well-being created by way of investment, mainly by public, but also some private, spending, with the result that they write off expenditure at the time that it is incurred and then appear to be continually surprised that later income is higher than they expected.

This is the real message that comes out of this chart when the finding is extrapolated appropriately. This is not the point that the Financial Times made about it. But the key issue is that the ONS is so blinded by its neoliberal assumptions, and its refusal to consider double entry when undertaking its accounting, and therefore the relationship between income and capital, and current and future returns, that it produces deeply misleading information, the consequence of which is that we all suffer excess downward pressure on government spending, quite inappropriately.

It really is time that we had an appropriate Office for National Statistics. One that understood economic reality, temporality, the relationship between income and capital, and the need for double-entry bookkeeping to ensure that appropriate checks and balances are reflected in the data that is produced.
