A couple of points
First, I am a bit late to this Op-Ed by Charles Koch but it so plainly illustrates a common fallacy I have to bring it back up. Koch writes
Years of tremendous overspending by federal, state and local governments have brought us face-to-face with an economic crisis. Federal spending will total at least $3.8 trillion this year—double what it was 10 years ago. And unlike in 2001, when there was a small federal surplus, this year’s projected budget deficit is more than $1.6 trillion.
The clear implication is that our budget deficit is the result of overspending. Now there are a lot of reasons people will point to as to why that’s not the case this time, the economy, the Bush Tax cuts, etc.
However, I want to make the more general point that spending is pretty much never the cause of budget deficits. Or, to be a bit more formal, variations in spending do not predict variations in the deficit. Variations in tax revenue, however, do predict variations in the deficit.
We can look at the US experience quickly

The blue line is spending, the redline is tax receipts, the green line is the deficit. Actually the green line is “government savings” which is the inverse of the deficit. So when the green line goes down the deficit gets bigger.
You can see that dips in the redline are associated with dips in government savings. Surges in the redline are associated with surges in government savings.
Now of course the deficit is mechanically related to spending and revenues, so what does it really mean to say that revenues are “more predicative.” It simply means that revenues bounce around more than spending and where revenues bounce so does the deficit. Spending is more or less smooth. Its only real changes are associated with war and peace.
Which brings me to a second point. Arnold Kling says
Everybody talks about a monetary "exit strategy" once a strong recovery takes hold. But what about a fiscal exit strategy? Other than Ron Paul, does anyone have several hundred billion in spending cuts ready to go?
Tyler Cowen’s NYT column is on what he calls "fiscal illusion." Maybe it should be the "fiscal allusion," because he alludes to so many things, or the "fiscal elusion," because the implications of his writing may be elusive. But one interpretation is that we need fiscal rules, because discretionary fiscal policy is biased toward deficit. That is, the Keynesian prescription is for surpluses when times are good and deficits when times are bad, but the Keynesian prescription is only taken when times are bad.
There are a myriad of problems that cause the Keynesian prescription of saving when times are good and deficits when times are bad to go awry.
However, one of them is that continued emphasis on the spending side of the budgetary equation. Arnold is looking at spending cuts as an exit strategy. Both proponents and detractors of stimulus use the word as a synonym for government spending.
It would be simpler and easier if stimulus were a synonym for broad based tax cuts. For example, small and potentially ineffectual as it might have been, no one is talking about how we need to keep the tax rebate of 2008 going.
The Making Work Pay Credit of 2009, 2010 was similarly jettisoned though there was a 2% payroll credit in its place. Still I predict that will be gotten rid of when its term expires as well.
No one has a problem letting broad based tax cuts go. They have a problem letting upper income tax cuts go and entitlement spending go. So, lets steer the focus towards broad based tax cuts as the Keynesian remedy.

Just a quick note: “That is, the Keynesian prescription is for surpluses when times are good and deficits when times are bad, but the Keynesian prescription is only taken when times are bad.”
We do have Keynesian prescriptions that disappear when times are good. We call it unemployment insurance. The thing is that we need a more robust mechanism whereby the current extension system is systematic and becomes active in each state/region during high unemployment in order to stabilize the local economy until the region can recover.

Excellent analysis. Thank you.
I actually posted this same chart three months ago, but missed the easy road to the obvious conclusion your red line indicates. Through more tortuous reasoning, I did eventually decide, though not in exactly your well chosen words, that except for military spending, “spending is pretty much never the cause of budget deficits.”

It’s great to have you validate my observation.
Here’s an observation on simple Keynesianism.

Is the drop in revenue due to tax cuts or a depressed economy?

I guess my attention wandered, because I failed to notice how badly off track you go after the Kling quote.

The point of Keynes is not to run deficits, per se. Surely you must know this !?!
The point is that when there is an aggregated demand shortfall, government needs to spend to alleviate it. Deficits are a byproduct.

To think tax cuts meet this need is not only unbelievably obtuse, it is the triumph of ideology over reality. It’s really a shame, since I want to think better of you than this.
We’ve been cutting taxes for 30 years, and the result – an economy that stagnated for decades and then tanked.
That’s the reality — if it matters.
How can you be so right for half a post, then totally blow it?
Honest to god, Karl, I’m almost ready to give up on you.
Now I must go hug a squid.

The point is deficits. Deficits are how aggregate demand is stimulated. That’s why, as Krugman argued, there wasn’t much Keynesian stimulus in the Great Depression (increases in taxes canceled out increases in spending). Technically, Herbert Hoover’s term was more Keynesian than F.D.R’s first.

No, no, and more no. Deficits are the means, not the end.
And only deficits caused by spending, not those caused by revenue reduction.
Otherwise, the last 30 years would have been the great golden age, instead of the great stagnation.
Your Tabarrok link reads well, but Hoover raised taxes in ’32, and the recovery began in 33. Every time taxes were raised, unemployment went down. The recession of ’37 – 38 was caused by reducing spending to balance the budget. The data is all here.

I don’t often disagree with Krugman, but I don’t know how he can say the New Deal didn’t work, when the GDP gap was completely filled by 1941 – just shortly before we entered WW II.
If he said the depression dragged on longer that it should have because spending was anemic, I’d buy into it.
Cheers!

Both obviously. What is not so obvious is that depressed economy is the result of tax cuts. The result is the worst wealth disparity in this country since 1929 – remember what happened then? Deregulation and too much wealth in too few hands leads to mis-allocation of resources Fla swamp land and the stock market in the 20′s (after the top rate was reduced from about 70% to 25% in 1920.) More recently, rolling bubbles in stocks, real estate, commodities, weird financial instruments that nobody understands, and now commodities again.

I’m still wondering about the graph. It appears that there was a period of slower spending growth in the Clinton years, and this slower growth is what allowed revenues to catch up to it. The pace of spending growth took off again during the Bush years. Is the issue really that spending isn’t causing deficits or is it that the sudden sharp decreases in revenue in the last two recessions (larger than any previous drops) we not properly matched with decreases in spending?
It appears that a Clinton spending growth rate would have given us a properly Keynesian cycle in the 2001 recession. If that could have been maintained through about 2006, then the Bush spending growth rate could have been maintained from there and the Great Recession would have looked rather normal. This would even have kept the 2003 tax cuts.
But what I’d also really like to see is a breakdown of the revenue. Income Tax vs. Corporate Tax vs. Federal Reserve Operations, perhaps Income Tax broken out by brackets, that sort of thing. That might go a long way to explain the huge drops in revenue from the last two recessions, which are where the real story lies.

Don’t forget the higher taxes during the Clinton years.

Haven’t forgotten them. I’m wondering how well things could have been smoothed out by adjusting spending and keeping revenue fixed. It’s Reagan tax rates, Bush tax rates, Clinton tax rates, then Bush rates. No changes there.
