The International Monetary Fund Accidentally Provides Strong Evidence for the Laffer Curve

As a general rule, the International Monetary Fund is a statist organization. Which shouldn’t be too surprising since its key “shareholders” are the world’s major governments.

And when you realize who controls the purse strings, it’s no surprise to learn that the bureaucracy is a persistent advocate of higher tax burdens and bigger government. Especially when the IMF’s politicized and leftist (and tax-free) leadership dictates the organization’s agenda.

Which explains why I’ve referred to that bureaucracy as a “dumpster fire of the global economy” and the “Dr. Kevorkian of global economic policy.”

I always make sure to point out, however, that there are some decent economists who work for the IMF and that they occasionally are allowed to produce good research. I’ve favorably cited the bureaucracy’s work on spending caps, for instance.

But what amuses me is when the IMF tries to promote bad policy and accidentally gives me powerful evidence for good policy. That happened in 2012, for example, when it produced some very persuasive data showing that value-added taxes are money machines to finance a bigger burden of government.

Well, it’s happened again, though this time the bureaucrats inadvertently just issued some research that makes the case for the Laffer Curve and lower corporate tax rates.

A Left-Wing Tax Victory that Is Actually a Triumph for Supply-Side Economics

Our statist friends like high taxes for many reasons. They want to finance bigger government, and they also seem to resent successful people, so high tax rates are a win-win policy from their perspective.

They also like high tax rates to micromanage people’s behavior. They urge higher taxes on tobacco because they don’t like smoking. They want higher taxes on sugary products because they don’t like overweight people. They impose higher taxes on “adult entertainment” because…umm…let’s simply say they don’t like capitalist acts between consenting adults. And they impose higher taxes on tanning beds because…well, I’m not sure. Maybe they don’t like artificial sun.

Give their compulsion to control other people’s behavior, these leftists are very happy about what’s happened in Berkeley, California. According to a study published in the American Journal of Public Health, a new tax on sugary beverages has led to a significant reduction in consumption.

Here are some excerpts from a release issued by the press shop at the University of California Berkeley.

…a new UC Berkeley study shows a 21 percent drop in the drinking of soda and other sugary beverages in Berkeley’s low-income neighborhoods after the city levied a penny-per-ounce tax on sugar-sweetened beverages. …The “Berkeley vs. Big Soda” campaign, also known as Measure D, won in 2014 by a landslide 76 percent, and was implemented in March 2015. …The excise tax is paid by distributors of sugary beverages and is reflected in shelf prices, as a previous UC Berkeley study showed, which can influence consumers’ decisions. …Berkeley’s 21 percent decrease in sugary beverage consumption compares favorably to that of Mexico, which saw a 17 percent decline among low-income households after the first year of its one-peso-per-liter soda tax that its congress passed in 2013.

I’m a wee bit suspicious that we’re only getting data on consumption by poor people.

Why aren’t we seeing data on overall soda purchases?

Honest Leftist Admits Desire for Spite-Driven Tax Policy

Every so often, I’ll assert that some statists are so consumed by envy and spite that they favor high tax rates on the “rich” even if the net effect (because of diminished economic output) is less revenue for government.

In other words, they deliberately and openly want to be on the right side (which is definitely the wrong side) of the Laffer Curve.

Just in case you think I’m exaggerating in order to make my opponents look foolish, check out this poll of left-wing voters who strongly favored soak-the-rich tax hikes even if there was no extra tax collected.

But now I have an even better example.

Writing for Vox, Matthew Yglesias openly argues that we should be on the downward-sloping portion of the Laffer Curve. Just in case you think I’m exaggerating, “the case for confiscatory taxation” is part of the title for his article.

Here’s some of what he wrote.

Maybe at least some taxes should be really high. Maybe even really really high. So high as to useless for revenue-raising purposes — but powerful for achieving other ends. We already accept this principle for tobacco taxes. If all we wanted to do was raise revenue, we might want to slightly cut cigarette taxes. …But we don’t do that because we care about public health. We tax tobacco not to make money but to discourage smoking.

The tobacco tax analogy is very appropriate.

Indeed, one of my favorite arguments is to point out that we have high taxes on cigarettes precisely because politicians want to discourage smoking.

As a good libertarian, I then point out that government shouldn’t be trying to control our private lives, but my bigger point is that the economic arguments about taxes and smoking are the same as those involving taxes on work, saving, investment.

Needless to say, I want people to understand that high tax rates are a penalty, and it’s particularly foolish to impose penalties on productive behavior.

But not according to Matt. He specifically argues for ultra-high tax rates as a “deterrence” to high levels of income.

If we take seriously the idea that endlessly growing inequality can have a cancerous effect on our democracy, we should consider it for top incomes as well. …apply the same principle of taxation-as-deterrence to very high levels of income. …Imagine a world in which we…imposed a 90 percent marginal tax rate on salaries above $10 million. This seems unlikely to raise substantial amounts of revenue.

I suppose we should give him credit for admitting that high tax rates won’t generate revenue. Which means he’s more honest than some of his fellow statists who want us to believe confiscatory tax rates will produce more money.

But honesty isn’t the same as wisdom.

Debunking the Debunking of Dynamic Scoring and the Laffer Curve

Many statists are worried that Republicans may install new leadership at the Joint Committee on Taxation (JCT) and Congressional Budget Office (CBO).

This is a big issue because these two score-keeping bureaucracies on Capitol Hill tilt to the left and have a lot of power over fiscal policy.

The JCT produces revenue estimates for tax bills, yet all their numbers are based on the naive assumption that tax policy generally has no impact on overall economic performance. Meanwhile, CBO produces both estimates for spending bills and also fiscal commentary and analysis, much of it based on the Keynesian assumption that government spending boosts economic growth.

I personally have doubts whether congressional Republicans are smart enough to make wise personnel choices, but I hope I’m wrong.

Matt Yglesias of Vox also seems pessimistic, but for the opposite reason.

He has a column criticizing Republicans for wanting to push their policies by using “magic math” and he specifically seeks to debunk the notion - sometimes referred to as dynamic scoring or the Laffer Curve - that changes in tax policy may lead to changes in economic performance that affect economic performance.

He asks nine questions and then provides his version of the right answers. Let’s analyze those answers and see which of his points have merit and which ones fall flat.

But even before we get to his first question, I can’t resist pointing out that he calls dynamic scoring “an accounting gimmick from the 1970s” in his introduction. That is somewhat odd since the JCT and CBO were both completely controlled by Democrats at the time and there was zero effort to do anything other than static scoring.

I suppose Yglesias actually means that dynamic scoring first became an issue in the 1970s as Ronald Reagan (along with Jack Kemp and a few other lawmakers) began to argue that lower marginal tax rates would generate some revenue feedback because of improved incentives to work, save, and invest.

Now let’s look at his nine questions and see if we can debunk his debunking:

Laffer Curve Explains Why Obama’s Class-Warfare Tax Policy Won’t Work

My main goal for fiscal policy is shrinking the size and scope of the federal government and lowering the burden of government spending. But I’m also motivated by a desire for better tax policy, which means lower tax rates, less double taxation, and fewer corrupting loopholes and other distortions.

One of the big obstacles to good tax policy is that many statists think that higher tax rates on the rich are a simple and easy way of financing bigger government. I’ve tried to explain that soak-the-rich tax policies won’t work because upper-income taxpayers have considerable ability to change the timing, level, and composition of their income.

Simply stated, when the tax rate goes up, their taxable income goes down. And that means it’s not clear whether higher tax rates lead to more revenue or less revenue. This is the underlying principle of the Laffer Curve.For more information, here’s a video from Prager University, narrated by UCLA Professor of Economics Tim Groseclose:

Groseclose does an excellent job, and I particularly like the data showing that the rich paid more to the IRS following Reagan’s tax cuts.

Boost Worker Pay - and Make the United States More Competitive - by Gutting the Corporate Income Tax

The business pages are reporting that Chrysler will be fully owned by Fiat after that Italian company buys up remaining shares.

I don’t know what this means about the long-term viability of Chrysler, but we can say with great confidence that the company will be better off now that the parent company is headquartered outside the United States.

This is because Chrysler presumably no longer will be obliged to pay an extra layer of tax to the IRS on any foreign-source income.

Italy, unlike the United States, has a territorial tax system. This means companies are taxed only on income earned in Italy but there’s no effort to impose tax on income earned - and already subject to tax - in other nations.

Under America’s worldwide tax regime, by contrast, U.S.-domiciled companies must pay all applicable foreign taxes when earning money outside the United States - and then also put that income on their tax returns to the IRS!

And since the United States imposes the highest corporate income tax in the developed world and also ranks a dismal 94 out of 100 on a broader measure of corporate tax competitiveness, this obviously is not good for jobs and growth.

No wonder many American companies are re-domiciling in other countries!

Maybe the time has come to scrap the entire corporate income tax. That’s certainly a logical policy to follow based on a new study entitled, “Simulating the Elimination of the U.S. Corporate Income Tax.”

Written by Hans Fehr, Sabine Jokisch, Ashwin Kambhampati, Laurence J. Kotlikoff, the paper looks at whether it makes sense to have a burdensome tax that doesn’t even generate much revenue.

The U.S. Corporate Income Tax…produces remarkably little revenue - only 1.8 percent of GDP in 2013, but entails major compliance and collection costs. The IRS regulations detailing corporate tax provisions are tome length and occupy small armies of accountants and lawyers. …many economists…have suggested that the tax may actually fall on workers, not capitalists.

Progress on the Laffer Curve*

The title of this piece has an asterisk because, unfortunately, we’re not talking about progress on the Laffer Curve in the United States.

Instead, we’re discussing today how lawmakers in other nations are beginning to recognize that it’s absurdly inaccurate to predict the revenue impact of changes in tax rates without also trying to measure what happens to taxable income (if you want a short tutorial on the Laffer Curve, click here).

But I’m a firm believer that policies in other nations (for better or worse) are a very persuasive form of real-world evidence. Simply stated, if you’re trying to convince a politician that a certain policy is worth pursuing, you’ll have a much greater chance of success if you can point to tangible examples of how it has been successful.

That’s why I cite Hong Kong and Singapore as examples of why free markets and small government are the best recipe for prosperity. It’s also why I use nations such as New Zealand, Canada, and Estonia when arguing for a lower burden of government spending.

And it’s why I’m quite encouraged that even the squishy Tory-Liberal coalition government in the United Kingdom has begun to acknowledge that the Laffer Curve should be part of the analysis when making major changes in taxation.

UK Laffer CurveI don’t know whether that’s because they learned a lesson from the disastrous failure of Gordon Brown’s class-warfare tax hike, or whether they feel they should do something good to compensate for bad tax policies they’re pursuing in other areas, but I’m not going to quibble when politicians finally begin to move in the right direction.


The Wall Street Journal opines that this is a very worthwhile development.

Chancellor of the Exchequer George Osborne has cut Britain’s corporate tax rate to 22% from 28% since taking office in 2010, with a further cut to 20% due in 2015. On paper, these tax cuts were predicted to “cost” Her Majesty’s Treasury some £7.8 billion a year when fully phased in. But Mr. Osborne asked his department to figure out how much additional revenue would be generated by the higher investment, wages and productivity made possible by leaving that money in private hands.

By the way, I can’t resist a bit of nit-picking at this point. The increases in investment, wages, and productivity all occur because the marginal corporate tax rate is reduced, not because more money is in private hands.

I’m all in favor of leaving more money in private hands, but you get more growth when you change relative prices to make productive behavior more rewarding. And this happens when you reduce the tax code’s penalty on work compared to leisure and when you lower the tax on saving and investment compared to consumption.
