The IMF’s Fiscal Monitor report released this month had this to say about debt:
There is a negative relationship between initial government debt and subsequent per capita GDP growth. The fitted line (OLS) of a scatter plot of initial debt against subsequent growth over five-year periods shows a coefficient of initial debt of -0.025 (Figure 1). Taken at face value, this suggests that a 10 percentage point of GDP increase in initial debt is associated with a slowdown in per capita GDP growth of 0.25 percentage points. This magnitude is consistent with that obtained using econometric estimation (see below). Second, the average growth rate during periods of rising debt is lower than that during the periods of falling debt (Figure 2).
The graphs are revealing, accessed through the link on page 63 of the report. They obliterate Rudd’s tax-spend-debt agenda.
A recent article in the WSJ by Allan Meltzer, professor of economics at Carnegie Mellon University makes much the same point:
Keynesians who think reducing public spending during a recession is a disastrous error should recall that they warned British Prime Minister Margaret Thatcher in 1981 that Britain would never recover if she continued with her tight fiscal and monetary policy during Britain’s deep recession. Mrs. Thatcher declined to take their advice. Expectations about Britain’s future changed for the better, and a long, productive recovery began soon after.
Greece’s government should take heart from her example. The new government in Britain might remember this as well. And so might the Keynesians in the Obama administration.
More historical background here. Peter Costello outlined in his book that he was given much the same warning when he took the Treasury reigns, and look what happened to the economy and budget.
