financial times

it's 11 months since martin wolf, the "premier financial and economics writer in the world," dissected the gop and supply-side economics on his financial times blog, but apparently nobody noticed on this side of the pond, because virtually all players in government and media are still digging in their heels while sinking into quicksand.

so, in hopes that someone will stumble across it this time, here's an excerpt and a link:

My reading of contemporary Republican thinking is that there is no chance of any attempt to arrest adverse long-term fiscal trends should they return to power. Moreover, since the Republicans have no interest in doing anything sensible, the Democrats will gain nothing from trying to do much either. That is the lesson Democrats have to draw from the Clinton era’s successful frugality, which merely gave George W. Bush the opportunity to make massive (irresponsible and unsustainable) tax cuts. In practice, then, nothing will be done.

Indeed, nothing may be done even if a genuine fiscal crisis were to emerge. According to my friend, Bruce Bartlett, a highly informed, if jaundiced, observer, some “conservatives” (in truth, extreme radicals) think a federal default would be an effective way to bring public spending they detest under control. It should be noted, in passing, that a federal default would surely create the biggest financial crisis in world economic history.

To understand modern Republican thinking on fiscal policy, we need to go back to perhaps the most politically brilliant (albeit economically unconvincing) idea in the history of fiscal policy: “supply-side economics”. Supply-side economics liberated conservatives from any need to insist on fiscal rectitude and balanced budgets. Supply-side economics said that one could cut taxes and balance budgets, because incentive effects would generate new activity and so higher revenue.

The political genius of this idea is evident. Supply-side economics transformed Republicans from a minority party into a majority party. It allowed them to promise lower taxes, lower deficits and, in effect, unchanged spending. Why should people not like this combination? Who does not like a free lunch?

How did supply-side economics bring these benefits? First, it allowed conservatives to ignore deficits. They could argue that, whatever the impact of the tax cuts in the short run, they would bring the budget back into balance, in the longer run. Second, the theory gave an economic justification – the argument from incentives – for lowering taxes on politically important supporters. Finally, if deficits did not, in fact, disappear, conservatives could fall back on the “starve the beast” theory: deficits would create a fiscal crisis that would force the government to cut spending and even destroy the hated welfare state.

In this way, the Republicans were transformed from a balanced-budget party to a tax-cutting party. This innovative stance proved highly politically effective, consistently putting the Democrats at a political disadvantage. It also made the Republicans de facto Keynesians in a de facto Keynesian nation. Whatever the rhetoric, I have long considered the US the advanced world’s most Keynesian nation – the one in which government (including the Federal Reserve) is most expected to generate healthy demand at all times, largely because jobs are, in the US, the only safety net for those of working age.

True, the theory that cuts would pay for themselves has proved altogether wrong. That this might well be the case was evident: cutting tax rates from, say, 30 per cent to zero would unambiguously reduce revenue to zero. This is not to argue there were no incentive effects. But they were not large enough to offset the fiscal impact of the cuts (see, on this, Wikipedia and a nice chart from Paul Krugman).

Indeed, Greg Mankiw, no less, chairman of the Council of Economic Advisers under George W. Bush, has responded to the view that broad-based tax cuts would pay for themselves, as follows: “I did not find such a claim credible, based on the available evidence. I never have, and I still don’t.” Indeed, he has referred to those who believe this as “charlatans and cranks”. Those are his words, not mine, though I agree. They apply, in force, to contemporary Republicans, alas,

Since the fiscal theory of supply-side economics did not work, the tax-cutting eras of Ronald Reagan and George H. Bush and again of George W. Bush saw very substantial rises in ratios of federal debt to gross domestic product. Under Reagan and the first Bush, the ratio of public debt to GDP went from 33 per cent to 64 per cent. It fell to 57 per cent under Bill Clinton. It then rose to 69 per cent under the second George Bush. Equally, tax cuts in the era of George W. Bush, wars and the economic crisis account for almost all the dire fiscal outlook for the next ten years (see the Center on Budget and Policy Priorities). [more]
