The political genius of supply-side economics

July 25, 2010 4:18pm

The future of fiscal policy was intensely debated in the FT last week. In this Exchange, I want to examine what is going on in the US and, in particular, what is going on inside the Republican party. This matters for the US and, because the US remains the world’s most important economy, it also matters greatly for the world.

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).

Today’s extremely high deficits are also an inheritance from Bush-era tax-and-spending policies and the financial crisis, also, of course, inherited by the present administration. Thus, according to the International Monetary Fund, the impact of discretionary stimulus on the US fiscal deficit amounts to a cumulative total of 4.7 per cent of GDP in 2009 and 2010, while the cumulative deficit over these years is forecast at 23.5 per cent of GDP. In any case, the stimulus was certainly too small, not too large.

The evidence shows, then, that contemporary conservatives (unlike those of old) simply do not think deficits matter, as former vice-president Richard Cheney is reported to have told former treasury secretary Paul O’Neill. But this is not because the supply-side theory of self-financing tax cuts, on which Reagan era tax cuts were justified, has worked, but despite the fact it has not. The faith has outlived its economic (though not its political) rationale.

So, when Republicans assail the deficits under President Obama, are they to be taken seriously? Yes and no. Yes, they are politically interested in blaming Mr Obama for deficits, since all is viewed fair in love and partisan politics. And yes, they are, indeed, rhetorically opposed to deficits created by extra spending (although that did not prevent them from enacting the unfunded prescription drug benefit, under President Bush). But no, it is not deficits themselves that worry Republicans, but rather how they are caused: deficits caused by tax cuts are fine; but spending increases brought in by Democrats are diabolical, unless on the military.

Indeed, this is precisely what John Kyl (Arizona), a senior Republican senator, has just said:

“[Y]ou should never raise taxes in order to cut taxes. Surely Congress has the authority, and it would be right to — if we decide we want to cut taxes to spur the economy, not to have to raise taxes in order to offset those costs. You do need to offset the cost of increased spending, and that’s what Republicans object to. But you should never have to offset the cost of a deliberate decision to reduce tax rates on Americans”

What conclusions should outsiders draw about the likely future of US fiscal policy?

First, if Republicans win the mid-terms in November, as seems likely, they are surely going to come up with huge tax cut proposals (probably well beyond extending the already unaffordable Bush-era tax cuts).

Second, the White House will probably veto these cuts, making itself even more politically unpopular.

Third, some additional fiscal stimulus is, in fact, what the US needs, in the short term, even though across-the-board tax cuts are an extremely inefficient way of providing it.

Fourth, the Republican proposals would not, alas, be short term, but dangerously long term, in their impact.

Finally, with one party indifferent to deficits, provided they are brought about by tax cuts, and the other party relatively fiscally responsible (well, everything is relative, after all), but opposed to spending cuts on core programmes, US fiscal policy is paralysed. I may think the policies of the UK government dangerously austere, but at least it can act.

This is extraordinarily dangerous. The danger does not arise from the fiscal deficits of today, but the attitudes to fiscal policy, over the long run, of one of the two main parties. Those radical conservatives (a small minority, I hope) who want to destroy the credit of the US federal government may succeed. If so, that would be the end of the US era of global dominance. The destruction of fiscal credibility could be the outcome of the policies of the party that considers itself the most patriotic.

In sum, a great deal of trouble lies ahead, for the US and the world.

Where am I wrong, if at all?

He sounds like a commie librul to me. I bet he ain't been to church in years. Why should I listen to a man who's turned his back on God and God's awesome creation - the United States of America?

Its interesting that none of the wingnuts have come out to condemn this well thought out, fact driven criticism, from a very well informed fellow from the other side of the pond, that rips to shreds the economic basis of the modern Republican party.

Maybe our local wing nuts can't read that many words at one time, so are powerless to see the strength of the argument.

There's nothing new worth discussing in the piece. If the Democrats are so wonderful why is unemployment stubbornly high and consumer confidence so low. It has nothing to do with the Bush era tax cuts and the Dems are free not to renew them.

The Dems now say deficits don't matter because there's no crowding out on the bond market and interest rates are low so let's blow money anything and hope something positive happens.

Well, it interesting not a single liberal had a worthwhile comment because Obama has had his and half and the Democrat Congress has had four years at the helm and nothing positive to show except more excuses and blaming the GOP for everything. It's grown tiresome.

[mendeleev 68]

Alien, perhaps, represents one of those with reading or contextual challenges.

He seems to think that anyone who comments on US politics does so from the inside. Wolf is by no means inside the US political dialogue. That's part of the point of the post.

Wolf, a Brit with pretty moderate tendencies, given their polity, makes observations across 30 years of Republican delusion. It is concerning that delusion that Wolf asks, where, if anywhere, is he wrong.

It would be refreshing if Alien and his ilk could address the criticism head-on.

I don't expect it -- I don't expect the ability for intellectual engagement -- I'm just hoping.

Alien: take up the challenge if you can. Read Wolf's post carefully and tell us where, if anywhere, he is wrong.

I already went over it and you said zip in defense. Repeating yourself means you don't understand much beyond cut and paste skills. You can always tell a poster that doesn't know his stuff. He just keeps repeating read the article as if that defects any and all criticism.

Think for yourself. What was new about the piece? Which legislation has the GOP successfully killed under Obama? Where the Obama economic success stories?

You guys have nothing left except hoping for something all criticism of Obama will magically be transmuted into some silly racist quote to distract voters in November.

It's late and don't feel like ripping the article to shreds if you don't feel answering a few simple questions. It's common courtesy.

Killed, not much. Heavily neutered? Just about everything.

If Republicans really care about protected the American people as they claim, more of them would have voted for financial reform. But in the end, the good ole boys are more win out.

The success, is in the fact that in all the dire predictions of depression, double dip recession, never happened.

You are correct but are Democrats any better at this or smarter in managing anything really? Democrats like to cling to pie-in-the-sky ideas like green and assume these things will create jobs out of thin air. Furthermore, a large faction of the party [libs] have not been interested in anything work-related post 60's yet apparently now have the answers to job creation and so forth. Forty years too late, especially when considering that while libs or their mommies and daddies were dancing and tripping, nobodies like Canadians and Australians built countries offering Q.O.L that even 50,000 San Frans cannot possibly come close to competing with.

What I do agree with is that Republicans also have no idea and along with libertarians are promoting dangerous policies that will make the country suffer in the long run. Ignorantly ignoring the realities and operating environment of the 21st century global environment; furthermore, neglecting how poorly the US compares in terms of things like infrastructure, QOL and so forth to other first world countries.

I agree.

I hang on to hope that most Americans are wising up to the empty promises of "tax cuts to solve our economic problems." It's like some of these fad diets where you can eat what you want and still lose weight.

Martin Wolf is the smoochiest on the FT staff, in my opinion; I would totally be crushing on him if I hadn't seen him up close and in person. It takes a special kind of kink for that.

Anyway, I'm with novotul on this -- I'm not really sure where those who do not agree with Wolf's analysis (with the exception of BY) are making actual points about WHY they do not agree, except on the basis that this is obviously a librul piece. Furthermore, unless I'm having one of those reading comprehension: FAIL days, I can't really see where this is a pro-Democrat piece at all. It is a critique of the Republicans, but that does not necessarily predicate support of the other party. If anything, it is a condemnation of the entire US system (with a tiny "woooo Britain" bit at the end).

An attack on supply side economics is an attack on Saint Ronnie. Once that is done, blaming the attack on Democrats is Pavlovian.

[luckytxn 2,264]

I agree pretty much with what he says. I was very happy when the tax cuts happened and actually saw the revenues rise. That had shocked me. What was wrong with supply side and showed me that the Neocons were wrong was that they also didn't back up what they promised and give us less Government but actually gave us more and thus what ever increase in revenue was off set by increased spending. I remember when Reagan came on the tube and said that a expensive military system was being stopped and that it would save us so much money and then in the next paragraph announce a even larger new system that was even more expensive. #######.

The one president that did what I want my government to do and that is at the least a balanced budget was Clinton. Sure he was forced to go with the tax cuts because of the GOP having the congress and he was thwarted on health care but he was in office and did give us a surplus and even paid down the deficit. Kudo's are deserved.
