The Laffer Curve
Marginally Useful Material Launcher ^ | 30 January 2004 | Robert Sturgeon

Posted on 01/30/2004 7:51:52 PM PST by MegaSilver

Some of you may share the mistaken belief that the Laffer Curve, named for Dr. Arthur Laffer, was tested and found wanting during the Reagan Administration. Nothing could be farther from the truth. There are two possible causes for your error. The first is that you may simply not know what the Laffer Curve is. This, combined with a natural tendency to agree with the "conventional wisdom," may lead you to just mindlessly nod your head in agreement every time you hear some T.V. network reporter blithely dismiss the "discredited Laffer Curve."

The second possible cause for your error may be that you do not understand what results the Laffer Curve promises. This is really a part of the greater problem mentioned above, so let us begin there.

For us to gain a rudimentary understanding of the ideas incorporated into the Laffer Curve, we must understand a tiny bit about economics. Economics is really just basic human psychology as applied to money and business affairs. We assume that people will react to the realities of the world of money and business more or less like they react to any other set of stimuli. They tend to act in their own and their family and friends' best interests, as they see them. The Laffer Curve results from our assumptions about how people will react to varying rates of income taxation. Now we must put our understanding of human nature to work. We must ask ourselves two questions, the answer to the first being obvious, and the answer to the second being not so obvious, but just as certain. The first question is, "If the income tax rate is zero %, how much income tax revenue will be raised?" The answer is, of course, "None."

Now, here is where it gets a bit tougher. The second question is, "If the income tax rate is 100%, how much income tax revenue will be raised?" To answer this question, we must place ourselves in the position of an income earner who faces a tax rate of 100% on every extra dollar he earns. Will he have any reason whatsoever to earn any more money? The answer is, "No, he won't." He will refrain from any activities likely to result in taxable income. So the income tax revenue from a 100% income tax will be zero, or nearly zero. There will always be a few suckers who go ahead and earn some money, only to have it taxed away. But the number of people willing to do so must be exceedingly small. For all practical purposes, the number is zero.

Okay, now we get to the nub of the "infamous" Laffer Curve. We must take the ideas discussed above and reach some conclusions. The reasoning goes like this: If a zero % income tax rate brings in zero revenue, and if a 100% income tax rate brings in zero revenue, the tax rate which will bring in the most revenue must be somewhere between zero % and 100%. It necessarily follows that in a given economy, there is some optimal income tax rate which will bring in the most revenue possible. In that economy, a lower than optimal rate will bring less revenue, and a higher than optimal rate also will bring in less revenue. Are we all still together here? Did you get that? If not, go back and do it again. Keep doing it until you get it.

Okay, that is all the Laffer Curve claims. Let's all say this together, "In any given economy, it is possible that the income tax rates are already too high, and if the authorities wish to bring in more income tax revenue, they must lower the tax rates." Do we all understand that? Even the Democrats amongst us?

The Laffer Curve does not claim that lowering income tax rates will always bring in more revenue. It only claims that a lower income tax rate may bring in more revenue. If the tax rates are already very low, lowering the rates may not bring in more revenue. But if the rates are too high, lowering the rates will bring in more revenue.

The problem people tend to have regarding the Laffer Curve is that they confuse economics with their political considerations. Many people have political reasons to desire high income tax rates on the earnings of the rich. They wish to prevent the rich from earning more money, even if the resulting tax revenue is smaller than it would otherwise be, and the economy less productive than it would otherwise be. These people do not believe that the income tax on the rich can ever be "too high." They are willing to deprive the government of revenue and deprive the economy of the productivity of the rich, all for the sake of their politics. There really is no arguing this point, as it is merely the outward manifestation of envy.

The Laffer Curve does not address questions of envy and redistributionist politics. It only addresses the question of how to have the healthiest economy producing the highest income tax revenue.

The Laffer Curve does not claim to know exactly what tax rate is the "right" tax rate. In fact, the only way to know if the current tax rates are too high is to lower them, and see whether revenues increase or not. If the revenues increase, the rates were too high. If the revenues decrease, the rates were too low. Of course, it would be equally valid to run the experiment the other way around: raise the tax rates and observe the results. The choice is the politicians' to make, based upon whether the current rates "seem" to be high or low. In 1981, the rates seemed rather high. The Laffer Curve experiment showed that the rates were, indeed, too high.

Now, let us consider whether the Laffer Curve "failed" to deliver on its promises during the Reagan administration. Remember, the Laffer Curve does not promise to balance the budget. The Laffer Curve does not promise to solve social problems. The Laffer Curve does not promise to force elected representatives to propose and enact lower spending programs. The Laffer Curve only promises that, if the tax rates are too high and they get lowered, revenues will increase. Income taxes were lowered (and "flattened") during the Reagan administration. Income tax revenues increased. In fact, they increased a great deal. Unfortunately, neither the Republican Reagan administration nor the Democrat-controlled Congress were interested in lowering the rate of growth in federal spending. While the income tax revenues increased substantially, federal spending increased even more. The result was that the federal government ran up a staggering national debt. But please, let's not blame it on the Laffer Curve!

As a business student, I can testify that the first time I saw the Laffer Curve, it made sense. It's just conventional wisdom. Of course, the *ss-kissing media would never let us know that.

I was an econ major when Reagan was still cleaning up after Carter. While the leftists in the profession were still pooh-poohing Dr.Laffer's very logical thesis which proceeded to prove itself, they were justifying Carter's gross mismanagement of the economy with the Phillips Curve-- which attempted to explain why inflation and unemployment could both continue to rise until the public turned to the saving graces of a planned economy.

This is why the ruling Marxists in our current intelligensia have resorted to different tactics now-- they are determined to push their version of free trade and open borders until the middle class disappears and only a multi-cultural ruling elite are left at the top of the pyramid to manage the rest of us livestock.

The Laffer curve was "invented/drawn" by Laffer on a napkin in a restaurant. It lacked much substantive content then, and lacks much substantive content now. Of course a 50% tax rate will bring in more revenues than a 99% tax rate. It is those noisome more "marginal" percentage figures, that are the rub. On that, Laffer provides no assistance.

By the way, for purposes of full disclosure, Laffer was once a professor of mine. When he was, I had almost as much hair as he did. No longer. Recently, his cousin, was a hostile expert witness in a trial in which I was called upon to litigate. I quite enjoyed shredding cousin Laffer. The subject was check kiting. The opposing counsel "assumed" I also sported a CPA in his closing brief. The assumption was erroneous, but I took it as a compliment. And so it goes.

The news media has taken on themselve to "educate" us as to whatever it is! Lot of it is that they themselves don't understand it.

They should stick to just reporting the fact and let us do the intrepreting.

Of couse, that's just wishful thinking. Oh, well!

This is a good commentary. The Laffer Curve is a great idea. I can deal with a healthy debate on the shape of the curve tho.

Nobody knows the shape, even the approximate shape, although the shape obviously varies over time based on a whole host of factors, macro, micro, and cultural. The data is two "noisy" because there are too many variables. Awareness of the unknown is a key step to good judgment, and the pursuit of knowledge.

By the way, the shape may reverse direction for awhile. Higher tax rates up to a point might force folks to work harder to maintain their standard of living. Oh the horror.

I'm sure it did, since it's all about maximizing revenue, something all businesses and governments seek to do. The difference between the two, however, is that the government has the legitimate threat of force on its side--they can just stick a gun in our faces and say, "pay up, sucka". I think it was Madison that said the power to tax is the power to destroy, and today taxation is as much a tool used to destroy the opposition (and conversely reward the loyal) as it is a revenue-raising tool.

Ah, I remember the Laffer curve concept. It was in Econ class way back when I had more hair and was a little less cynical.

I certainly do not profess any great expertise in the 'soft science' of Economics. I decided to continue my education in the more concrete sciences of biology and chemistry.

One thing about Laffer that has always bugged me, and maybe some enlightened soul could clarify it for the class:

While Laffer indicated that IF taxes were TOO high, lowering them would actually increase revenue, he never really indicated how much was TOO much. What is the proper balance of taxation and maximum revenue?

(Yes, this is a devil's advocate question, so please refrain from your Adam Smith/Milton Friedman retorts. I'm already a member of the choir).

Laffer may have been a bit dumb (and frankly he was never a leading intellect in economics ever; he got by with his connections and charm, both of which were considerable), but he is not stupid. As I said before, nobody knows, in part because it is a moving target, and in part because there are so many variables, that it is next to impossible either to verify the hypothesis, or falsify it, within the reasonable range of public policy choices. Hypotheses that cannot be verified or falsified are worthless.

That's precisely the argument that Democrats use to rationalize higher taxes. We'll just work harder and there won't be negative economic effects.

I recall hearing 15%, I don't know from where or from who, but 15% keeps sticking in my mind.

Heh-heh! I agree with your analysis! Be as ambiguous as possible and you can make a living as an Economist......... or a Meterologist!

The MDSpinboyRedux hypothesis:

Tomorrow it will either rain or it won't.

I'm a genius! Colleges around the nation should dedicate many hours of class discussion to my astute observation!

Are you thinking of Malcolm Forbes?

Didn't he push the 15% idea back in 1992 when he ran for Pres?

"Awareness of the unknown is a key step to good judgment, and the pursuit of knowledge."

What is this "awareness of the unknown?" Some kind of lawyer's algebra? If it is unknown, then who could possibly be aware of it? Who, exactly are the elite that are posessed of this special awareness that no one knows a danged thing about, huh? Please reply immediately!!!

I guess the French Revolution din't behead 'em all.

Hey Sinner, you need God! He uses 10% flat!!! Pretty successful for the clerics, for nearly 2000 years, even with many "backsliders" not paying most of the time. How 'bout dat?

Any scientist in most fields will amaze you with a rendition of what is known to be unknown in his or her discipline. What do you think electricity really is, and why it has the properties it does? What do you think causes gravity to be a force? What about matter really generates it, and why? Why does molten matter generate magnetic fields? Just why do the magnetic fields flip from time to time? Why is the ocean salty? How many species of life do you think on on this planet? Is it more likely to be 2 million, or closer to 200 hundred million? What do you think is "known" about that?

The Laffer Curve is a rough graphic representation of the very very old "Law of Diminishing Returns", which must go back ... I would guess centuries ... in the field of economics. Somehow Laffer gets credit for it. Me, I'm looking for a way to draw a cartoon that will get me the credit for inventing Newton's Second Law of Thermodynamics.

Well the sexy part of the Laffer Curve, as publicized, is the Law of Negative Returns, not diminishing returns. You mission, should you choose to accept it, is to find where that begins, and why and when, and depending on what. A piece of cake, no?
