Krugman on the IMF paper
by digby
The IMF has just released a new paper on austerity that is kind of heavy going (unnecessarily, I think), but ends up making a simple but important point.
Suppose that a government imposes fiscal austerity in a realistic fashion, with spending cuts getting steadily deeper relative to baseline over a period of several years. If the negative impact of these cuts is fairly large — which all the evidence coming in suggests is the case under current liquidity-trap conditions — and if the country starts from a fairly high level of debt — as the austerity countries do — something alarming is likely to happen. Instead of falling, the ratio of debt to GDP is likely to rise for years.
In part this is because a weaker economy shrinks revenues, offsetting a large part of the direct austerity. What pushes it over the top is the weakening of GDP, which increases the ratio.
I ran my own version of their simulations for a hypothetical country — call it Osbornia — which starts with debt at 100 percent of GDP and a budget deficit that would, left to itself, be consistent with a stable debt ratio thanks to 2 percent growth and 2 percent inflation. On this economy I impose 5 years of tightening at the rate of 1 percent of potential GDP each year, with a multiplier of 1.3 (which is about where recent estimates have been converging). Output ends up 6.5 percent below the baseline; debt looks like this:
Why does this matter? As the paper says,
Although this effect is not long-lasting and debt eventually declines, it could be an issue if financial markets focus on the short-term behavior of the debt ratio, or if country authorities engage in repeated rounds of tightening in an effort to get the debt ratio to converge to the official target.
(My emphasis).And, of course, this destructive behavior is especially likely if said country authorities are firm believers in the notion that austerity does not depress output; they’ll see the weak performance either as “structural” or as showing the need for more confidence. Either way, they’ll see it as a reason to tighten even more.
Sound like anyone you know?
Uhm, yes. And how convenient that will be for the anti-government, anti-tax zealots.
But hey, I hear that if we can make a deal right now to only impose the trillions in cuts we’ve already agreed to in the short run and commit to cut trillions more from the “entitlements” down the road, we’ll take all this messy deficit schmeficit stuff off the table and everything will be smooth sailing. What could go wrong?
Update: This piece pressuring liberals to come around on entitlements by holding them responsible for the hideous discretionary cuts shows just how this is supposed to work:
“The aging population and the growth of health-care costs make enacting reforms to entitlements imperative. Enacting them now would help the economy by reducing uncertainty. This would also instill more confidence in government, give people time to adjust and release the pressure on the small portion of the budget that so far has absorbed virtually all of the cuts. “
Really? It looks to me as if the evidence Krugman cites says exactly the opposite.
But don’t let that stand in the way of shamefully holding liberals responsible for what the centrists and conservatives are doing to this country. That’s par for the course.
