Verligte Economics

Nobel  laureate economist, Paul Krugman, has a blogpost summarizing his (and some of Brad DeLong’s) arguments against imposing fiscal austerity in the short-term.   I realize that the verkrampte wing of the economic commentariat seem to be in the majority at present, so unfortunately the wise good sense of Krugman and DeLong seems unlikely to prevail.  But I want to note their arguments for the record so that, 2 or 5 years from now, when we are again (or still) in recession, we can look back and weep.

So, one more time: here’s an attempt to put together some key arguments about why the rush to fiscal austerity is deeply misguided.
Let me start with the budget arithmetic, borrowing an approach from Brad DeLong. Consider the long-run budget implications for the United States of spending $1 trillion on stimulus at a time when the economy is suffering from severe unemployment.
That sounds like a lot of money. But the US Treasury can currently issue long-term inflation-protected securities at an interest rate of 1.75%. So the long-term cost of servicing an extra trillion dollars of borrowing is $17.5 billion, or around 0.13 percent of GDP.
And bear in mind that additional stimulus would lead to at least a somewhat stronger economy, and hence higher revenues. Almost surely, the true budget cost of $1 trillion in stimulus would be less than one-tenth of one percent of GDP – not much cost to pay for generating jobs when they’re badly needed and avoiding disastrous cuts in government services.
But we can’t afford it, say the advocates of austerity. Why? Because we must impose pain to appease the markets.
There are three problems with this claim.
First, it assumes that markets are irrational – that they will be spooked by stimulus spending and/or encouraged by austerity even though the long-run budget implications of such spending and/or austerity are trivial.
Second, we’re talking about punishing the real economy to satisfy demands that markets are not, in fact, making. It’s truly amazing to see so many people urging immediate infliction of pain when the US government remains able to borrow at remarkably low interest rates, simply because Very Serious People believe, in their wisdom, that the markets might change their mind any day now.
Third, all this presumes that if the markets were to lose faith in the US government, they would be reassured by short-term fiscal austerity. The available facts suggest otherwise: markets continue to treat Ireland, which has accepted savage austerity with little resistance, as being somewhat riskier than Spain, which has accepted austerity slowly and reluctantly.
In short: the demand for immediate austerity is based on the assertion that markets will demand such austerity in the future, even though they shouldn’t, and show no sign of making any such demand now; and that if markets do lose faith in us, self-flagellation would restore that faith, even though that hasn’t actually worked anywhere else.
