Personal saving rose again in the second quarter. “Does this mean the stimulus tax cut has failed, as the 2008 tax cut stimulus did?”, asks The National Journal.

My answer:

Martin Feldstein and others predicted that the tax-cut component of the 2009 fiscal stimulus package would have substantially less expansionary bang-for-the-buck than the spending component of the package, because much of the tax cut would be saved, as had been the case with the 2008 tax cut.  (“Bang for the buck” in this case could be defined as demand stimulus divided by budget cost.)   We knew this from Milton Friedman’s permanent income hypothesis, or even from good old Keynesian multiplier theory.

But in February President Obama had to get those last three (Republican) votes to pass the stimulus bill in the Senate, and those three Senators insisted on raising the tax cut component of the stimulus package a bit and lowering the spending component. Their motivation presumably was to mollify their fellow Republicans, many of whom still claim that ONLY tax cuts provide stimulus, and that spending does not (and perhaps even has a negative effect) — which is even more extreme than the claim that a tax cut creates stimulus equal to spending. After the failures of the Bush tax cuts (and Reagan’s before him), I don’t know if any economists still cling to such “supply sider” notions — or indeed if these congressmen would be able to state their logic. Regardless, I think the Feldstein prediction has been borne out since then.   Talk about irony!   The Reagan tax cuts of 1981-83 and the Bush tax cuts of 2001-03 were both explicitly designed to boost saving — hence their focus on capital income and higher income brackets — and yet in both cases private saving fell in their aftermath.   The tax cuts of January 2008 and February 2009 were both explicitly designed to boost consumption; yet private saving rose in their aftermath !   

Fortunately, the majority of the Obama stimulus package took the form of increased spending, much of which has yet to come.

None of this is to deny that efficiency is an important consideration, and cost-benefit calculations should always enter into the choice of both what kind of tax cuts to adopt and what kind of spending increases to adopt. But if it is short-term demand stimulus we are after, and we are, then government spending gives more bang for the buck than tax cuts.

A panel on Supply Side Economics in Washington, September 12, included statistics on the superior performance of the American economy under President Clinton compared to his Republican successor. (The graph to the right, from Ettlinger & Irons, shows the first term of each administration.  The growth gap during the second terms was even wider.)  Former Treasury Secretary Larry Summers gave some statistics that included Democratic versus Republican presidents throughout the postwar period.   As others have also pointed out, the Democratic record dominates to a surprising extent.   (The event was jointly sponsored by the Center for American Progress and the Economic Policy Institute.)

 By coincidence, in a column in that day’s Wall Street Journal, Donald Luskins sought to “get something settled once and for all. Have the stock markets and the economy historically done better under Democrats or Republicans?”

 These matters are not solely of interest to historians or economists.   The presidential campaign of Senator John McCain appears set to drive its wagon down the same road in which Reagan and Bush have already worn deep ruts.   The candidate is apparently selling the same snake oil:  he says he believes that tax cuts increase revenues.   His principle policy director disavows the Laffer Principle, just as the economists who advised Presidents Reagan and Bush did.   But the views of the economic advisers are not what determines what these presidents do. 

“The Queen in Alice in Wonderland  said that, with practice, she was able to believe as many as six impossible things before breakfast.   Most of us are more limited in our capacity for credulity.  If John McCain believes both the Laffer Proposition (tax cuts raise revenues) and Starve the Beast (higher revenues lead to higher spending, anathema to conservatives), then as a good conservative, his duty is clear.  He ought to run on a truly novel platform of higher tax rates!   Why?   Higher tax rates would reduce revenues (this is what Laffer says would happen) and thereby reduce spending (this is what Starve the Beast says would happen).   
    

Seriously folks.   If McCain continues to propose extending the Bush tax cuts, he should at least be forced to choose between the Lafferite defense and the “Starve the Beast” defense. Only then can the rest of us know which of the two mutually inconsistent propositions to refute. 

I discussed my paper September 12, in a panel where Larry Summers and Gene Sperling also gave their thoughts on Supply Side Economics, at a joint meeting of the Center for American Progress  and the Economic Policy Institute.

In my earlier post, I catalogued some quotes from high Bush Administration officials asserting the Laffer claim that a cut in US tax rates stimulates income so much that the Treasury ends up taking in more revenue than before. I didn’t then quote in detail the extensive statements made by the Director of Office of Management and Budget, Joshua Bolten, in July 2005.

Director Bolton’s statements are of particular interest for several reasons. First, by 2005 it had become obvious to any objective observer that (1) the record budget surplus inherited by the Bush Administration had been quickly converted into a record budget deficit, and that (2) the aggressive Bush tax cuts were a major cause of that swing (as was the sharp acceleration in federal spending, both domestic and international, relative to the 1990s). Second, while the utterings of President Bush himself can in general perhaps be dismissed as not to be taken seriously, Bolten was the professional whose job is to be responsible for the integrity of the budget process. (Indeed, he is a higher-quality civil servant than some in the Bush Administration who have been quick to “bolt on” crazy ideological propositions to what should be serious positions.)

Here is what the OMB director had to say about the Laffer proposition:

“And with all those economic gains, we are also seeing more revenues coming into the Federal Treasury. We have arrived at this point largely because of this President’s and this Congress’ pro-growth policies, especially tax relief. Those policies have strengthened the economy, which is now producing better-than-expected revenues.” — Testimony of Joshua B. Bolten, Mid Session Reivioew of the President’s FY 2006 Budget Requst, Committee on the Budget, U.S. House of Representatives, page 1, para. 3.

And lots more:
“The tax cuts proposed by the President and enacted by Congress are not the [budget] problem. They are, and will be, part of the solution…Had Congress not enacted the President’s three tax relief packages, moreover, the economy would be substantially weaker than it is…The most effective way to lower future deficits is to grow the economy. And the President’s tax packages have been well designed to do precisely that.”

“…all economists, I think will agree very strongly that when you reduce taxes, put more money back into the economy, that has a feedback effect in the economy that causes growth and in turn increases receipts. And being able to measure those receipts, to see how much better the government’s fiscal situation is as a result of the tax cuts would be something I’d very much like to include in the numbers….We think we’ve done the right things by making the tax cuts to restore the economy to growth, because what got us into the difficulty deficit situation in the first place is the flagging growth, flagging receipts in the economy. We think the best way back is to restore the economy to growth, and restore receipts that correspond to it…. ”

Q: “…you’ve got a substantial drop in the deficit [forecasted] in 2005…”
A: “…there are other factors involved, and one of them is the ‘03 tax cut.”

– Press Briefing by OMB Director Josh Bolton, The White House, July 15, 2003.

Following up on my preceding post, I will here document who has said what.

High officials in the Reagan Administration apparently did subscribe to the Laffer Hypothesis:
• Reagan himself: “…our kind of tax cut will so stimulate the economy that we will actually increase government revenues…” July 7, 1981 speech 1/
• His Secretary of the Treasury, Don Regan, even after events had falsified the proposition to the satisfaction of most observers, wrote of his “very strong opinion that a tax cut would produce more revenue than a tax increase.”2/
Also: “The increase in revenues should be financed not by new and higher taxes, but by lower tax rates that would produce more money for the government by stimulating higher earnings by corporations and workers…” (p.173).

Similarly, high officials during the Bush era have also have been quoted saying that tax cuts, via faster growth, lead to higher tax revenues:
• President George W. Bush : “The best way to get more revenues in the Treasury is not raise taxes, slowing down the economy, it’s cut taxes to create more economic growth. That’s how you get more money into the U.S. Treasury.” — July 24, 2003.
• OMB Director Joshua Bolten, press conference July 2003; & WSJ, Dec. 10, 2003
• Majority Leader Tom DeLay: “We, as a matter of philosophy, understand that when you cut taxes the economy grows, and revenues to the government grow.” NYT, 3/31/04.
• Treasury Secretary John Snow, Congressional testimony, Feb. 7, 2006: “Lower tax rates are good for the economy and a growing economy is good for Treasury receipts.”
• CEA Chair Ed Lazear, press conference 2/12/07, “revenues have come in…higher than we predicted…because the economy has grown at a rate higher than we predicted…[T]he tax cuts…[were] at least in part responsible for making the economy grow.”

Most leading Republican economists who served as chief economic advisers to Presidents Reagan and Bush during their tax cutting frenzies, however, do not subscribe to the Laffer Hypothesis, and did not compromise their beliefs while in office. Three examples:

• Martin Feldstein: “I objected therefore to those supply-siders like Arthur Laffer who argued that a 30 percent across-the-board tax cut would also be self-financing because of the resulting increase in incentives to work.”3/
• Glenn Hubbard: “Although the economy grows in response to tax reductions… it is unlikely to grow so much that lost tax revenue is completely recovered by the higher level of economic activity.”4/
• Greg Mankiw: “Subsequent history failed to confirm Laffer’s conjecture that lower tax rates would raise tax revenue. When Reagan cut taxes after he was elected, the result was less tax revenue, not more.” 5/

1/ Feldstein, American Economic Policy in the 1980s (U. Chicago Press) 1994, p.21.
2/ Regan, For the Record (St. Martin’s Press: New York) 1988, (p.214).
3/ American Economic Policy in the 1980s ( U. Chicago Press) 1994, p.24 .
4/ Economic Report of the President (Government Printing Office) 2003, p.57-58.
5/ Principles of Economics (Dryden) 1998, p. 166.

I thought it would be useful to get all this into the record, since some observers have claimed that Reagan and Bush never subscribed to the Laffer hypothesis, while others have inaccurately accused Feldstein, Hubbard and Mankiw of selling out on this score.

So Arthur Laffer — still arguing the improbable “supply side” proposition that cutting income tax rates generally raises total tax revenue — is apparently now a special adviser to John McCain. And McCain has taken on a big consignment of the snake oil, to Greg Mankiw’s dismay. The political temptation for a Republican candidate to promise both lower tax rates and higher revenues is irresistible. The policy-makers who cut taxes when Ronald Reagan and George W. Bush, respectively, came to power subscribed to this claim. Remarkably, at the same time, the economists who were the chief economic advisers to Reagan and Bush during these tax cuts disavow the proposition that they increase revenue (Murray Weidenbaum, Martin Feldstein, Glenn Hubbard, Mankiw…) . Almost all serious economists – let us say Ph.D. economists – disagree with this proposition, with only a microscopic handful of exceptions like Laffer. Indeed some of the advisers who defend the Reagan and Bush economic policies claim that this formulation of supply side economics is a caricature, and was not the true rationale of the tax cuts. This wishful thinking is directly at odds with quotes from the presidents themselves and their Treasury secretaries and other economic officials, to the effect that tax cuts stimulate income so much as to produce more tax revenue. Laffer is not a straw man. (See my next post.)

Even more interesting, the academic defenders of the Republican tax cuts often offer a proposition that is diametrically opposed to the defense offered by their political masters. This is the famous “starve the beast” hypothesis: the claim that if you deprive the government of tax revenue, it will reduce government spending, which is of course viewed as a worthy objective. If this proposition were true, and the supply side hypothesis were also true, it would lead to the nonsensical proposition that Republican presidents should raise tax rates in order to reduce tax revenue (Laffer) and thereby reduce government spending (Starve the Beast). I challenge some candidate to run on that platform !

As it happens, there is abundant empirical evidence against both the Lafferite hypothesis and the Starve the Beast hypothesis. In other words, just because two propositions are diametrically opposed doesn’t mean they are not both wrong. I hope that in this election campaign, the media do something they have failed to do in the past. If McCain proposes extending the Bush tax cuts, he should at least be forced to choose between the Lafferite defense, which tends to be driven more by political expediency, and the “Starve the Beast” defense, which has more support among at least some reputable Republican economists. Only then can the rest of us know which of the two propositions to refute.
