Plan B or not to B

Plan B was launched over the weekend to much fanfare. There was much excited analysis in The Guardian. In The Observer, one hundred economists told George Osborne that Plan A is failing.

I will focus on one small aspect, the Plan B critique of current fiscal policies. Behind Plan B is the idea that "current policies … may do the very opposite of their avowed intention, by actually increasing the deficit." The logic underlying this argument extends he Keynesian multiplier: public spending cuts put people out of jobs and reduce their incomes, so that they pay less in tax; if taxes fall by more than spending, the deficit will widen, ending in higher, not lower public debt. Turn this argument around and there would be scope, apparently, for Britain to spend its way out of debt.

Another idea behind Plan B is that "the UK national debt is not large by long-run historical standards." Judging from the historical record, it seems, Britain can easily afford a higher public debt. While debt reduction may sound virtuous, it is suggested, it is currently unecessary (and the policies designed to achieve it may be actively harmful).

The outcome of Plan A, according to Plan B, is economic "sado-masochism": We are enduring the pain of public spending cutbacks to no purpose (since the cutbacks will not reduce the deficit) when the purpose (to reduce the public debt) is not even necessary in the first place. Or is there pleasure for some in the pain of others?

This weekend, by coincidence, the Royal Economic Society Newsletter (no. 155, October 2011) published my short paper Surely You're Joking, Mr Keynes?This paper makes two points.

First, it's true that Britain has carried much larger debts relative to its GDP in the past, but this was almost entirely the result of wars; do we have a comparable excuse today? It's completely unhistorical, moreover, to compare Britain's credit today with that obtainable when Britain was the world's dominant economic and financial power. The world has changed; is that something we still need to get used to?

On this, I conclude:

Historically, having a debt twice the size of the national income has been a sign that something went terribly wrong: a run of major wars, for example. Faced with the worst recession in 80 years, the British government was right to let its budget go into deficit temporarily. At that moment an increase in Britain’s debt was inevitable. Now it looks essential to bring it back under control over a few years.

Second, there is no robust evidence in the historical data that deficit reduction is self-defeating. There is claimed to be evidence, but I show that it crumbles when you touch it. On average, in fact, deficit reduction has reduced the national debt -- as one would expect.

Here, I conclude:

It remains true that, once the public debt is set on a particular course, it is hard to change that course quickly. But this is only momentum that takes time to reverse; there is no evidence of destabilizing pushback from Keynesian multipliers.

To sum up: I have taken aim at two common beliefs about the British public finances. One is that we should borrow our way out of recession; the other is that we can spend our way of debt. These beliefs are based on intriguing stories. But, like many good stories, they are fictions. Our country cannot spend its way out debt. In today’s world, we can afford to borrow much less than in the past, and that may be just as well.
