Dan Mitchell article The Tradeoff Between Tax Progressivity and Economic Output

The Tradeoff Between Tax Progressivity and Economic Output

Almost everybody (even, apparently, Paul Krugman) agrees that you don’t want to be on the downward-sloping part of the Laffer Curve.

That’s where higher tax rates do so much economic damage that government collects even less revenue.

But I would argue that tax increases that produce more revenue also are a bad idea.

Sometimes they are even a terrible idea. For instance, there are tax increases that would destroy $5 of private income for every $1 of revenue they collect.

That would not be a good deal, at least for those of us who aren’t D.C. insiders.

Heck, according to research from economists at the University of Chicago and Federal Reserve, there are some tax increases that would destroy even greater levels of private income for every additional dollar that politicians got to spend.

The simple way of thinking about this is that you don’t want to be at the revenue-maximizing point of the Laffer Curve.

Because the closer you get to that point, the greater the damage to the private sector compared to any revenue collected.

To help understand this key point, let’s review a new study from Spain’s central bank. Authored by Nezih Guner, Javier López-Segovia and Roberto Ramos, it investigates the impact of higher tax rates.

They first look at what happens when progressivity (τ) is increased.

In the first experiment, we…change…the entire tax schedule, so that all households below the mean labor income face lower average taxes, while those above the mean income face higher average taxes. Since…richer individuals face higher taxes, all else equal, the government collects more taxes. All else, however, is not equal since more progressive taxes lower incentives to work and save. As a result, a higher τ might result in lower, not higher, revenue.The question is where the top of the Laffer curve is. We find that the tax revenue from labor income is maximized with τ = 0 .19. The increase in tax collection is, however, very small: the tax revenue from labor income increases only by 0.82% (or about 0.28% of the GDP). The tax revenue from labor income is, however, only one part of the total tax collection. There are also taxes on capital and consumption. With τ = 0 .19, while the tax collection from labor income is maximized, the total tax collection declines by 1.55%. This happens since with a higher τ, the aggregate labor, capital and output decline significantly. Indeed, the total tax collection falls for any increase in τ, and the level of τthat maximizes total tax revenue is much lower, τ = 0 .025, than its benchmark value.

The key takeaway is that more progressivity puts Spain on the wrong (downward-sloping) side of the Laffer Curve.

Here’s Table 6, which shows big declines in output, labor supply, and investment as progressivity increases.

Here’s some of the accompanying explanation.

The upper panel of Table 6 shows that capital, effective labor and output decline monotonically with τ. Hence, as the economy moves from τ = 0 .1581 to τ = 0 .19, the government is collecting higher taxes from labor, but the aggregate labor supply and output decline. For τ higher than 0.19, the decline in labor supply dominates and tax collection from labor income is lower. …The level of τ that maximizes the total tax collection is 0.025, which implies significantly less progressive taxes than in the benchmark economy. …In the economy with τ = 0 .025, the aggregate capital, labor and output increase significantly. The steady state output, for example, is almost 11 percentage points higher than the benchmark economy. As a result, the government is able to collect higher taxes despite lowering taxes on the top earners.

The authors also put together an estimate of Spain’s Laffer Curve, with the red-dashed line showing total tax revenue.

The authors also looked at what happens if politicians simply increase top tax rates.

They found that there are scenarios that would enable the Spanish government to collect more revenue.

We find that it is possible to generate higher total tax revenue by increasing taxes on the top earners.The main message of our quantitative exercises is that…the extra revenue is not substantial. Higher progressivity has significant adverse effects on output and labor supply, which limits the room for collectinghigher taxes. As a result, the only way to generate substantial revenue is with significant increases in marginal tax rates for a large group

But notice that those higher taxes would have “significant adverse effects on output and labor supply.”

Which brings us back to the earlier discussion about the desirability of causing a lot of damage to the private economy in order to give politicians a bit more money to spend.

The authors have a neutral tone, but the rest of should be able to draw the logical conclusion that higher taxes would be a big mistake for Spain.

And since the underlying economic principles apply in all nations, we also should conclude that higher taxes would be a big mistake for the United States.

P.S. We conducted a very successful experiment in the 1980sinvolving lower tax rates. Biden now wants to see what happens if we try the opposite approach.

Paul Krugman Admits Big Government Means Huge Tax Increases for Ordinary Americans

While Paul Krugman sometimes misuses and misinterprets numbers for ideological reasons (see his errors regarding the United States, France, Canada, the United States, Estonia, Germany, the United States, and the United Kingdom), he isn’t oblivious to reality.

At least not totally.

He’s acknowledged, for instance, that there is a Laffer Curve and that tax rates can become so onerous that tax revenues actually decline.

Now he’s had another encounter with the real world.

In a column that was mostly a knee-jerk defense of Biden’s class-warfare tax policy, Krugman confessed yesterday that big government ultimately means big tax increases for lower-income and middle-class people.

…is trying to “build back better” by taxing only the very affluent feasible? Is it wise? …There’s a good case that the kind of society progressives want us to become, with a very strong social safety net, can’t be paid for just by taxing the rich.A country like Denmark, for example, does have a high top tax rate… But Denmark also has very high middle-class taxation, in particular a 25 percent value-added tax, effectively a national sales tax. …the fact that even the Nordic countries feel compelled to raise a lot of money from the middle class suggests that there are limits…to how much you can raise just by taxing the rich. So if you want Medicare for all, Nordic levels of support for child care and families in general, and so on, just raising taxes on the 400K-plus elite won’t get you there.

It may not happen often, but Krugman is completely correct.

European-sized government requires European-style taxes on everyone. And that means a big value-added tax, as Krugman notes. And it almost certainly also means big energy taxes, higher payroll taxes, and much higher income tax rates on middle-class taxpayers.

This chart from Brian Riedl shows that government spending already was on track to become a bigger burden for the American economy, and Biden is proposing to go even faster in the wrong direction.

The growing gap between the blue lines and red lines implies giant tax increases. At the risk of understatement, there’s no way to finance that ever-expanding government by just pillaging upper-income taxpayers.

By the way, Krugman is right about big government leading to higher taxes on ordinary people, but he’s wrong about the desirability of that outcome.

He wants us to think that big government means a “better America,” but all the economic data tells a different story. A bigger fiscal burden means much lower living standards.

Dear Mr. President,

______________________________

Dan Mitchell shows how ignoring the Laffer Curve is like running a stop sign!!!!

I’m thinking of inventing a game, sort of a fiscal version of Pin the Tail on the Donkey.

Only the way it will work is that there will be a map of the world and the winner will be the blindfolded person who puts their pin closest to a nation such asAustralia or Switzerland that has a relatively low risk of long-run fiscal collapse.

That won’t be an easy game to win since we have data from the BISOECD, and IMF showing that government is growing far too fast in the vast majority of nations.

We also know that many states and cities suffer from the same problems.

A handful of local governments already have hit the fiscal brick wall, with many of them (gee, what a surprise) from California.

The most spectacular mess, though, is about to happen in Michigan.

The Washington Post reports that Detroit is on the verge of fiscal collapse.

After decades of sad and spectacular decline, it has come to this for Detroit: The city is $19 billion in debt and on the edge of becoming the nation’s largest municipal bankruptcy. An emergency manager says the city can make good on only a sliver of what it owes — in many cases just pennies on the dollar.

This is a dog-bites-man story. Detroit’s problems are the completely predictable result of excessive government. Just as statism explains the problems of Greece. And the problems of California. And the problems of Cyprus. And theproblems of Illinois.

I could continue with a long list of profligate governments, but you get the idea. Some of these governments are collapsing at a quicker pace and some at a slower pace. But all of them are in deep trouble because they don’t follow my Golden Rule about restraining the burden of government spending so that it grows slower than the private sector.

Detroit obviously is an example of a government that is collapsing sooner rather than later.

Why? Simply stated, as the size and scope of the public sector increased, that created very destructive economic and political dynamics.

More and more people got lured into the wagon of government dependency, which puts an ever-increasing burden on a shrinking pool of producers.

Meanwhile, organized interest groups such as government bureaucrats used their political muscle to extract absurdly excessive compensation packages, putting an even larger burden of the dwindling supply of taxpayers.

But that’s not the main focus of this post. Instead, I want to highlight a particular excerpt from the article and make a point about how too many people are blindly – perhaps willfully – ignorant of the Laffer Curve.

Check out this sentence.

Property tax collections are down 20 percent and income tax collections are down by more than a third in just the past five years — despite some of the highest tax rates in the state.

This is a classic “Fox Butterfield mistake,” which occurs when someone fails to recognize a cause-effect relationship. In this case, the reporter should have recognized that tax collections are down because Detroit has very high tax rates.

The city has a lot more problems than just high tax rates, of course, but can there be any doubt that productive people have very little incentive to earn and report taxable income in Detroit?

And that’s the essential insight of the Laffer Curve. Politicians can’t – or at least shouldn’t – assume that a 20 percent increase in tax rates will lead to a 20 percent increase in tax revenue. They also have to consider the degree to which a higher tax rate will cause a change in taxable income.

In some cases, higher tax rates will discourage people from earning more taxable income.

In some cases, higher tax rates will discourage people from reporting all the income they earn.

In some cases, higher tax rates will encourage people to utilize tax loopholes to shrink their taxable income.

In some cases, higher tax rates will encourage migration, thus causing taxable income to disappear.

Here’s my three-part video series on the Laffer Curve. Much of this is common sense, though it needs to be mandatory viewing for elected officials (as well as the bureaucrats at the Joint Committee on Taxation).

The Laffer Curve, Part I: Understanding the Theory

Uploaded by  on Jan 28, 2008

The Laffer Curve charts a relationship between tax rates and tax revenue. While the theory behind the Laffer Curve is widely accepted, the concept has become very controversial because politicians on both sides of the debate exaggerate. This video shows the middle ground between those who claim “all tax cuts pay for themselves” and those who claim tax policy has no impact on economic performance. This video, focusing on the theory of the Laffer Curve, is Part I of a three-part series. Part II reviews evidence of Laffer-Curve responses. Part III discusses how the revenue-estimating process in Washington can be improved. For more information please visit the Center for Freedom and Prosperity’s web site: http://www.freedomandprosperity.org

Part 2

Part 3

P.S. Just in case it’s not clear from the videos, we don’t want to be at the revenue-maximizing point on the Laffer Curve.

P.P.S. Amazingly, even the bureaucrats at the IMF recognize that there’s a point when taxes are so onerous that further increases don’t generate revenue.

P.P.P.S. At least CPAs understand the Laffer Curve, probably because they help their clients reduce their tax exposure to greedy governments.

P.P.P.P.S. I offered a Laffer Curve lesson to President Obama, but I doubt it had any impact.
