Archive for the ‘Marginal Tax Rate’ Category

When I give speeches in favor of tax reform, I argue for policies such as the flat tax on the basis of both ethics and economics.

The ethical argument is about the desire for a fair system that neither punishes people for being productive nor rewards them for being politically powerful. As is etched above the entrance to the Supreme Court, the law should treat everyone equally.

The economic argument is about lowering tax rates, eliminating double taxation, and getting rid of distorting tax preferences.

Today, let’s focus on the importance of low tax rates. More specifically, let’s look at why it’s important to have a low marginal tax rate, which is the rate that applies when people earn more income.

Here’s the example I sometimes use in my remarks. Imagine a taxpayer who earns $50,000 and pays $10,000 in tax.

With that information, we know the taxpayer’s average tax rate is 20 percent. But this information tells us nothing about incentives to earn more income because we don’t know the marginal tax rate that would apply if the taxpayer was more productive and earned another $5,000.

Consider these three simple scenarios with wildly different marginal tax rates.

  1. The tax system imposes a $10,000 annual charge on all taxpayers (sometimes referred to as a “head tax”). Under this system, our taxpayer pays that tax, which means the average tax rate on $50,000 of income is 20 percent. But the marginal tax rate would be zero on the additional $5,000 of income. In this system, the tax system does not discourage additional economic activity.
  2. The tax system imposes a flat rate of 20 percent on every dollar of income. Under this system, our taxpayer pays that tax on every dollar of income, which means the average tax rate on $50,000 of income is 20 percent. And the marginal tax rate would also be 20 percent on the additional $5,000 of income. In this system, the tax system imposes a modest penalty on additional economic activity.
  3. The tax system has a $40,000 personal exemption and then a 100 percent tax rate on all income about that level. Under this system, our taxpayer pays $10,000 of tax on $50,000 of income, which means an average tax rate of 20 percent. But the marginal tax rate on another $5,000 of income would be 100 percent. In this system, the tax system would destroy incentives for any additional economic activity.

These examples are very simplified, of course, but they accurately show how systems with identical average tax rates can have very different marginal tax rates. And from an economic perspective, it’s the marginal tax rate that matters.

Remember, economic growth only occurs if people decide to increase the quantity and/or quality of labor and capital they provide to the economy. And those decisions obviously are influenced by marginal tax rates rather than average tax rates.

This is why President Obama’s class-warfare tax policies are so destructive. This is why America’s punitive corporate tax system is so anti-competitive, even if the average tax rate on companies is sometimes relatively low.

And this is why economists seem fixated on lowering top tax rates. It’s not that we lose any sleep about the average tax rate of successful people. We just don’t want to discourage highly productive investors, entrepreneurs, and small business owners from doing things that result in more growth and prosperity for the rest of us.

We’d rather have the benign tax system of Hong Kong instead of the punitive tax system of France. Now let’s look at a real-world (though very unusual) example.

Writing for Forbes, a Certified Public Accountant explains why Cam Newton of the Carolina Panthers is guaranteed to lose the Super Bowl.

Not on the playing field. The defeat will occur when he files his taxes.

Remember when Peyton Manning paid New Jersey nearly $47,000 in taxes two years ago on his Super Bowl earnings of $46,000? …Newton is looking at a tax bill more than twice as much, which will swallow up his entire Super Bowl paycheck, win or lose, thanks to California’s tops-in-the-nation tax rate of 13.3%.

You may be wondering why California is going to pillage Cam Newton since he plays for a team from North Carolina, but there is a legitimate “nexus” for tax since the Super Bowl is being playing in California.

But it’s the level of the tax and marginal impact that matters. More specifically, the tax-addicted California politicians impose taxes on out-of-state athletes based on how many days they spend in the Golden State.

Before we get into the numbers, let’s do a quick review of the jock tax rules… States tax a player based on their calendar-year income. They apply a duty day calculation which takes the ratio of duty days within the state over total duty days for the year.

Now let’s look at the tax implication for Cam Newton.

If the Panthers win the Super Bowl, Newton will earn another $102,000 in playoff bonuses, but if they lose he will only net another $51,000. The Panthers will have about 206 total duty days during 2016, including the playoffs, preseason, regular season and organized team activities (OTAs), which Newton must attend or lose $500,000. Seven of those duty days will be in California for the Super Bowl… To determine what Newton will pay California on his Super Bowl winnings alone, …looking at the seven days Newton will spend in California this week for Super Bowl 50, he will pay the state $101,600 on $102,000 of income should the Panthers be victorious or $101,360 on $51,000 should they lose.

So what’s Cam’s marginal tax rate?

The result: Newton will pay California 99.6% of his Super Bowl earnings if the Panthers win. Losing means his effective tax rate will be a whopping 198.8%. Oh yeah, he will also pay the IRS 40.5% on his earnings.

In other words, Cam Newton will pay a Barack Obama-style flat tax. The rules are very simple. The government simply takes all your money.

Or, in this case, more than all your money. So it’s akin to a French-style flat tax.

Some of you may be thinking this analysis is unfair because California isn’t imposing a 99.6 percent or 198.8 percent tax on his Super Bowl earnings. Instead, the state is taxing his entire annual income based on the number of days he’s working in the state.

But that’s not the economically relevant issue. What matters if that he’ll be paying about $101,000 of extra tax simply because the game takes place in California.

However, if the Super Bowl was in a city like Dallas and Miami, there would be no additional tax.

The good news, so to speak, is that Cam Newton has a contract that would prevent him from staying home and skipping the game. So he basically doesn’t have the ability to respond to the confiscatory tax rate.

Many successful taxpayers, by contrast, do have flexibility and they are the job creators and investors who help decide whether states grow faster and stagnate. So while California will have the ability to pillage Cam Newton, the state is basically following a suicidal fiscal policy.

Basically the France of America. And that’s the high cost of high marginal tax rates.

Since I’m a big fan of the Laffer Curve, I’m always interested in real-world examples showing good results when governments reduce marginal tax rates on productive activity.

Heck, I’m equally interested in real-world results when governments do the wrong thing and increase tax burdens on work, saving, investment, and entrepreneurship (and, sadly, these examples are more common).

My goal, to be sure, isn’t to maximize revenue for politicians. Instead, I prefer the growth-maximizing point on the Laffer Curve.

In any event, my modest hope is that politicians will learn that higher tax rates lead to less taxable income. Whether taxable income falls by a lot or a little obviously depends on the specific circumstance. But in either case, I want policy makers to understand that there are negative economic effects.

Writing for Forbes, Jeremy Scott of Tax Notes analyzes the supply-side policies of Israel’s Benjamin Netanyahu.

Netanyahu…argued that the Laffer curve worked, and that his 2003 tax cuts had transformed Israel into a market economy and an engine of growth. …He pushed through controversial reforms… The top individual tax rate was cut from 64 percent to 44 percent, while corporate taxes were slashed from 36 percent to 18 percent. …Netanyahu credits these reforms for making Israel’s high-tech boom of the last few years possible. …tax receipts did rise after Netanyahu’s tax cuts. In fact, they were sharply higher in 2007 than in 2003, before falling for several years because of the global recession. …His tax cuts did pay for themselves. And he has transformed Israel into more of a market economy…In fact, the prime minister recently announced plans for more cuts to taxes, this time to the VAT and corporate levies.

Pretty impressive.

Though I have to say that rising revenues doesn’t necessarily mean that the tax cuts were completely self-financing. To answer that question, you have to know what would have happened in the absence of the tax cut. And since that information never will be available, all we can do is speculate.

That being said, I have no doubt there was a strong Laffer Curve response in Israel. Simply stated, dropping the top tax rate on personal income by 20 percentage points creates a much more conducive environment for investment and entrepreneurship.

And cutting the corporate tax rate in half is also a sure-fire recipe for improved investment and job creation.

I’m also impressed that there’s been some progress on the spending side of the fiscal ledger.

Netanyahu explained that the public sector had become a fat man resting on a thin man’s back. If Israel were to be successful, it would have to reverse the roles. The private sector would need to become the fat man, something that would be possible only with tax cuts and a trimming of public spending. …Government spending was capped for three years.

The article doesn’t specify the years during which spending was capped, but the IMF data shows a de facto spending freeze between 2002 and 2005. And the same data, along with OECD data, shows that the burden of government spending has dropped by about 10 percentage points of GDP since that period of spending restraint early last decade.

Here’s the big picture from the Fraser Institute’s Economic Freedom of the World. As you can see from the data on Israel, the nation moved dramatically in the right direction after 1980. And there’s also been an upward bump in recent years.

Since I’m not an expert on Israeli economic policy, I don’t know the degree to which Netanyahu deserves a lot of credit or a little credit, but it’s good to see a country actually moving in the right direction.

Let’s close by touching on two other points. First, there was one passage in the Forbes column that rubbed me the wrong way. Mr. Scott claimed that Netanyahu’s tax cuts worked and Reagan’s didn’t.

Netanyahu might have succeeded where President Reagan failed.

I think this is completely wrong. While it’s possible that the tax cuts in Israel has a bigger Laffer-Curve effect than the tax cuts in the United States, the IRS data clearly shows that Reagan’s lower tax rates led to more revenue from the rich.

Second, the U.S. phased out economic aid to Israel last decade. I suspect that step helped encourage better economic policy since Israeli policy makers knew that American taxpayers no longer would subsidize statism. Maybe, just maybe, there’s a lesson there for other nations?

During last night’s Democratic debate, Senator Bernie Sanders said he would not raise tax rates as high as they were in the 1950s. And if Twitter data is accurate, his comment about being “not that much of a socialist compared to [President] Eisenhower” was one of the evening’s most memorable moments.

But a clever line is not the same as smart policy. Promising not to raise top tax rates to 90 percent or above is hardly a sign of moderation from the Vermont politician.

Fortunately, not all Democrats are infatuated with punitive tax rates.

Or at least they didn’t used to be. When President John F. Kennedy took office, he understood that the Eisenhower tax rates (in fairness to Ike, he’s merely guilty of not trying to reduce confiscatory tax rates imposed by FDR) were harming the economy and JFK argued for across-the-board tax rate reductions.

…an economy hampered by restrictive tax rates will never produce enough revenues to balance our budget just as it will never produce enough jobs or enough profits. Surely the lesson of the last decade is that budget deficits are not caused by wild-eyed spenders but by slow economic growth and periodic recessions and any new recession would break all deficit records. In short, it is a paradoxical truth that tax rates are too high today and tax revenues are too low and the soundest way to raise the revenues in the long run is to cut the rates now.

Here’s a video featuring some of President Kennedy’s wisdom on lower tax rates.

If that wasn’t enough, here’s another video featuring JFK’s wisdom on taxation.

By the way, if Senator Sanders really wants the rich to pay more, one of the lessons reasonable people learned from the Kennedy tax cuts is that upper-income taxpayers respond to lower tax rates by earning and reporting more income. Here’s a chart from a study I wrote almost 20 years ago.

Last but not least, let’s preemptively address a likely argument from Senator Sanders. He might be tempted to say that he doesn’t want the 90-percent tax rate of the Eisenhower years, but that he’s perfectly content with the 70-percent top tax rate that existed after the Kennedy tax cuts.

But if that’s the case, instead of teaching Sanders a lesson from JFK, then he needs to learn a lesson from Ronald Reagan.

The tax-reform landscape is getting crowded.

Adding to the proposals put forth by other candidates (I’ve previously reviewed the plans offered by Rand Paul, Marco Rubio, Jeb Bush, Bobby Jindal, and Donald Trump), we now have a reform blueprint from Ted Cruz.

Writing for the Wall Street Journal, the Texas Senator unveiled his rewrite of the tax code.

…tax reform is a powerful lever for spurring economic expansion. Along with reducing red tape on business and restoring sound money, it can make the U.S. economy boom again. That’s why I’m proposing the Simple Flat Tax as the cornerstone of my economic agenda.

Here are the core features of his proposal.

…my Simple Flat Tax plan features the following: • For a family of four, no taxes whatsoever (income or payroll) on the first $36,000 of income. • Above that level, a 10% flat tax on all individual income from wages and investment. • No death tax, alternative minimum tax or ObamaCare taxes. • Elimination of the payroll tax and the corporate income tax… • A Universal Savings Account, which would allow every American to save up to $25,000 annually on a tax-deferred basis for any purpose.

From an economic perspective, there’s a lot to like. Thanks to the low tax rate, the government no longer would be imposing harsh penalties on productive behavior. Major forms of double taxation such as the death tax would be abolished, creating a much better environment for wage-boosting capital formation.

And I’m glad to see that the notion of a universal savings account, popularized by my colleague Chris Edwards, is catching on.

Moreover, the reforms Cruz is pushing would clean up some of the most complex and burdensome sections of the tax code.

But Cruz’s plan is not a pure flat tax. There would be a small amount of double taxation of income that is saved and invested, though the adverse economic impact would be trivial because of the low tax rate.

And the Senator would retain some preferences in the tax code, which is somewhat unfortunate, and expand the earned income credit, which is more unfortunate.

It maintains the current child tax credit and expands and modernizes the earned-income tax credit… The Simple Flat Tax also keeps the current deduction for all charitable giving, and includes a deduction for home-mortgage interest on the first $500,000 in principal.

But here’s the part of Cruz’s plan that raises a red flag. He says he wants a “business flat tax,” but what he’s really proposing is a value-added tax.

…a 16% Business Flat Tax. This would tax companies’ gross receipts from sales of goods and services, less purchases from other businesses, including capital investment. …My business tax is border-adjusted, so exports are free of tax and imports pay the same business-flat-tax rate as U.S.-produced goods.

His proposal is a VAT because wages are nondeductible. And that basically means a 16 percent withholding tax on the wages and salaries of all American workers (for tax geeks, this part of Cruz’s plan is technically a subtraction-method VAT).

Normally, I start foaming at the mouth when politicians talking about value-added taxes. But Senator Cruz obviously isn’t proposing a VAT for the purpose of financing a bigger welfare state.

Instead, he’s doing a swap, imposing a VAT while also getting rid of the corporate income tax and the payroll tax.

And that’s theoretically a good deal because the corporate income tax is so senselessly destructive (swapping the payroll tax for the VAT, as I explained a few days ago in another context, is basically a wash).

But it’s still a red flag because I worry about what might happen in the future. If the Cruz plan is adopted, we’ll still have the structure of an income tax (albeit a far-less-destructive income tax). And we’ll also have a VAT.

So what happens 10 years from now or 25 years from now if statists control both ends of Pennsylvania Avenue and they decide to reinstate the bad features of the income tax while retaining the VAT? They now have a relatively simple way of getting more revenue to finance European-style big government.

And also don’t forget that it would be relatively simple to reinstate the bad features of the corporate income tax by tweaking Cruz’s business flat tax/VAT.

By the way, I have the same specific concern about Senator Rand Paul’s tax reform plan.

My advice to both of them is to ditch the VAT and keep the payroll tax. Not only would that address my concern about enabling the spending proclivities of statists in the future, but I also think Social Security reform is more feasible when the system is financed by the payroll tax.

Notwithstanding my concern about the VAT, Senator Cruz has put forth a plan that would be enormously beneficial to the American economy.

Instead of being a vehicle for punitive class warfare and corrupt cronyism, the tax code would simply be the method by which revenue was collected to fund government.

Which gives me an opportunity to raise an issue that applies to every candidate. Simply stated, no good tax reform plan will be feasible unless it’s accompanied by a serious plan to restrain government spending.

It’s time for a lesson in tax economics.

Though hopefully today’s topic won’t be as dry and boring as my missives on more technical issues like depreciation and worldwide taxation.

That’s because we’re going to talk about the taxation of workers, which is something closer to home for most of us.

And our lesson comes from Belgium, where the government wants a “new social contract” based on lower “direct” taxes on workers in exchange for higher “indirect” taxes on consumers.

Here are some excerpts from a Bloomberg column by Jean-Michel Paul.

Belgium’s one-year-old government announced measures, radical by that country’s standards, to move the burden of taxation to consumption from labor.  The measures are being hailed as the start of a new social contract in the heart of Europe.

But before discussing this new contract, let’s look at how Belgium’s system evolved. Monsieur Paul explains that his nation has a bloated welfare state, which has resulted in heavy taxes on workers (vigorous tax competition precludes onerous taxes on capital).

…In order to sustain large government expenses of more than 50 percent GDP on top of servicing its debt, Belgium became the OECD’s second most-taxed economy. …Belgium made a choice: It decided to heavily tax labor, which it figured, wrongly, was stuck. At the same time, it decided to provide attractive tax treatment to highly mobile capital. The gambit meant that Belgium attracted a large number of wealthy families from higher tax countries, particularly France and the Netherlands, eager to take advantage of the low rates of tax on capital. However, Belgian workers got hammered. In 2014 Belgian workers were the most taxed labor in the developed world, taking home only 46 percent of employers’ labor costs.

Here’s a chart from the article, showing that Belgian workers are the most mistreated in the developed world.

Keep in mind, by the way, that average rates only measure the overall burden of taxation.

Marginal tax rates, which are what matters most for incentives, are even higher.

According to Wikipedia, the personal income tax has a top rate of 50 percent, and that punitive rate hits a lot of ordinary workers (it’s imposed on income “in excess of €37750”). But there’s also a 13 percent payroll tax on workers and a concomitant payroll tax of more than 30 percent on employers (which, needless to say, is borne by workers).

So an ambitious Belgian worker who wants to earn more money will be confronted by the ugly reality that the government will get the lion’s share of any additional income. Geesh, no wonder Belgium gets a high score (which is not a good outcome) in the World Bank’s “tax effort report card.”

Not surprisingly, high tax rates on labor have led to some predictably bad consequences.

The entrepreneurial class is voting with its feet and regular workers are being taxed into the unemployment line.

This unusual policy mix has increasingly created problems. …Educated professionals and entrepreneurs, those most in demand in other countries, have voted with their feet in borderless Europe. As a result, productivity growth has been limited and Belgium’s economy remained low-growth. Its business start-up rate is the second lowest of the EU. …Whole segments of the country’s industrial tissue, such as the automobile sector, have gradually closed down… This has led to what the European Commission described as “a chronic underutilisation of labour” (read: unemployment) especially among the least qualified and the young. Youth unemployment stands at over 22 percent. …In its 2015 country report the Commission noted that this “reflects Belgium’s high social security charges on labour, which add to the large tax wedge”

Given these horrid numbers, it’s understandable that some policy makers in Belgium want to make changes.

But as Americans have learned (very painfully), “change” doesn’t necessarily mean better policy.

So let’s see what Belgian policy makers have in mind.

The new policy…is to reduce taxes on labor and increase indirect taxes to compensate. Social Security taxes on companies are being reduced to 25 percent from 33 percent over the next two years, bringing an increase in the net after-tax income of 100 euros ($113) per month for low and middle-wage earners. This is mainly financed by an increase in value added tax on electricity consumption. …Belgium is the first to implement what some call a “social VAT” (a tax on consumption to finance social security). …it rewards work and may well change the entitlement mind-set that has hampered innovation and job growth for decades. …a significant step in the right direction, correcting some of the worst distortions of Belgium’s social model.

In other words, politicians in Belgium want to rearrange the deck chairs on the Titanic.

Workers will be allowed to earn more of their income when they earn it, but the government will grab more of their income when they spend it.

Now for the economics lesson.

People work because they want to earn money. And they want to earn money so they can spend it. In other words, as Adam Smith observed way back in 1776, “Consumption is the sole end and purpose of all production.”

Now ask yourself whether the change in Belgian tax policy will boost employment when there’s no change in the tax wedge between pre-tax income (the income you generate) and post-tax consumption (the income you get to spend)?

The answer presumably is no.

This doesn’t mean that the proposed reform is completely useless. It appears that the VAT increase is achieved by ending a preferential tax rate on electricity consumption. And since I don’t like distorting tax preferences, I’m guessing the net effect of the overall package is slightly positive.

In other words, the lower payroll tax rate is unambiguously good and the increase in the VAT burden is only partially bad (I would be more critical if the proposal included an increase in the VAT rate rather than the elimination of a preference).

That being said, now let’s address Belgium’s real problem. Simply stated, it’s impossible to have a good tax system when government spending consumes more than 50 percent of economic output.

In no uncertain terms, an excessive burden of government spending is the problem that needs to be solved.

P.S. Interestingly, Belgium’s tax shift is somewhat similar to Rand Paul’s tax plan. In addition to all the other changes envisioned by the Kentucky Senator, he would get rid of the payroll tax and replace it with a value-added tax.

P.P.S. In addition to much smaller government, I suspect Belgium also needs to split into two different countries.

P.P.P.S. To get an idea of Belgium’s challenge, the politicians in Brussels actually criticize Germany for being too capitalistic.

I’m pleasantly surprised by the tax plans proposed by Marco Rubio, Rand Paul, Jeb Bush, and Donald Trump.

In varying ways, all these candidate have put forth relatively detailed proposals that address high tax rates, punitive double taxation, and distorting tax preferences.

But saying the right thing and doing the right thing are not the same. I just did an interview focused on Donald Trump’s tax proposal, and one of my first points was that candidates may come up with good plans, but those proposals are only worthwhile if the candidates are sincere and if they intend to do the heavy lifting necessary to push reform through Congress.

Today, though, I want to focus on another point, which I raised starting about the 0:55 mark of the interview.

For the plans to be credible, candidates also need to have concomitant proposals to restrain the growth of federal spending.

I don’t necessarily care whether they balance the budget, but I do think proposals to reform and lower taxes won’t have any chance of success unless there are also reasonable plans to gradually shrink government spending as a share of economic output.

As part of recent speeches in New Hampshire and Nevada, I shared my simple plan to impose enough spending restraint to balance the budget in less than 10 years.

But those speeches were based on politicians collecting all the revenue projected under current law.

By contrast, the GOP candidates are proposing to reduce tax burdens. On a static basis, the cuts are significant. According to the Tax Foundation, the 10-year savings for taxpayers would be $2.97 trillion with Rand Paul’s plan, $3.67 trillion under Jeb Bush’s plan, $4.14 trillion with Marco Rubio’s plan, all the way up to $11.98 trillion for Donald Trump’s plan.

Those sound like very large tax cuts (and Trump’s plan actually is a very large tax cut), but keep in mind that those are 10-year savings. And since the Congressional Budget Office is projecting that the federal government will collect $41.58 trillion over the next decade, the bottom line, as seen in this chart, is that all of the plans (other than Trump’s) would still allow the IRS to collect more than 90 percent of projected revenues.

Now let’s make the analysis more realistic by considering that tax cuts and tax reforms will generate faster growth, which will lead to more taxable income.

And the experts at the Tax Foundation made precisely those calculations based on their sophisticated model.

Here’s an updated chart showing 10-year revenue estimates based on “dynamic scoring.”

The Trump plan is an obvious outlier, but the proposals from Jeb Bush, Rand Paul, and Marco Rubio all would generate at least 96 percent of the revenues that are projected under current law.

Returning to the original point of this exercise, all we have to do is figure out what level of spending restraint is necessary to put the budget on a glide path to balance (remembering, of course, that the real goal should be to shrink the burden of spending relative to GDP).

But before answering this question, it’s important to understand that the aforementioned 10-year numbers are a bit misleading since we can’t see yearly changes. In the real world, pro-growth tax cuts presumably lose a lot of revenue when first enacted. But as the economy begins to respond (because of improved incentives for work, saving, investment, and entrepreneurship), taxable income starts climbing.

Here’s an example from the Tax Foundation’s analysis of the Rubio plan. As you can see, the proposal leads to a lot more red ink when it’s first implemented. But as the economy starts growing faster and generating more income, there’s a growing amount of “revenue feedback.” And by the end of the 10-year period, the plan is actually projected to increase revenue compared to current law.

So does this mean some tax cuts are a “free lunch” and pay for themselves? Sound like a controversial proposition, but that’s exactly what happened with some of the tax rate reductions of the Reagan years.

To be sure, that doesn’t guarantee what will happen if any of the aforementioned tax plans are enacted. Moreover, one can quibble with the structure and specifications of the Tax Foundation’s model. Economists, after all, aren’t exactly famous for their forecasting prowess.

But none of this matters because the Tax Foundation isn’t in charge of making official revenue estimates. That’s the job of the Joint Committee on Taxation, and that bureaucracy largely relies on static scoring.

Which brings me back to today’s topic. The good tax reform plans of certain candidates need to be matched by credible plans to restrain the growth of federal spending.

Fortunately, that shouldn’t be that difficult. I explained last month that big tax cuts were possible with modest spending restraint. If spending grows by 2 percent instead of 3 percent, for instance, the 10-year savings would be about $1.4 trillion.

And since it’s good to reduce tax burdens and also good to restrain spending, it’s a win-win situation to combine those two policies. Sort of the fiscal equivalent of mixing peanut butter and chocolate in the famous commercial for Reese’s Peanut Butter Cups.

P.S. Returning to my interview embedded above, I suppose it’s worthwhile to emphasize a couple of other points.

P.P.S. Writing about the prospect of tax reform back in April, I warned that “…regardless of what happens with elections, I’m not overly optimistic about making progress.”

Today, I still think it’s an uphill battle. But if candidates begin to put forth good plans to restrain spending, the odds will improve.

While I sometimes make moral arguments against the current tax system (because it is corrupt, because it doesn’t treat people equally, because it provides unearned wealth for insiders, etc), my main arguments are based on economics.

High tax rates on workers and entrepreneurs discourage productive behavior.

Double taxation on income that is saved and invested discourages capital formation.

Tax preferences and other loopholes bribe people to use resources inefficiently.

These are the principles that explain why I like tax reform, why I promote the Laffer Curve, and why I advocate for tax competition.

Maybe it’s time, however, for a back-to-basics primer on taxes and behavior. That’s why I’m very glad that Professors Tyler Cowen and Alex Tabarrok of George Mason University (and the Marginal Revolution blog) are producing videos on various economic principles.

And I particularly like a video they produced which uses supply and demand curves to show how taxes reduce economic output.

But before we watch that video on taxes and “deadweight loss,” here’s a video on how supply and demand curves interact.

Feel free to skip this video if you feel confident in your understanding of these economic concepts (and also feel free to watch this video on the demand curve and this video on the supply curve if you don’t have any background knowledge and need to start at the beginning).

Now let’s look at their first-rate video on how taxes lead to less economic output and foregone value for both buyers and sellers.

Very well done. I particularly like the closing example showing how the so-called luxury tax backfired.

Here are a few of my thoughts to augment Professor Tabarrok’s analysis.

1. The video looks at how taxes affect the equilibrium level of output for an unspecified product. Keep in mind that this analysis applies to “products” such as labor and investment.

2. It should go without saying (but I’ll say it anyhow) that ever-higher tax rates impose ever-higher levels of deadweight loss.

3. The point about avoiding taxes on goods where there is high “elasticity” has important lessons for why it is foolish to impose class-warfare tax rates on people who have considerable control over the timing, level, and composition of their income.

4. This analysis does not imply that all taxes are bad. Or, to be more precise, the analysis does not lead to the conclusion that all taxes are counterproductive. If government uses money to provide valuable public goods, the overall effect on the economy may be positive.

P.S. I’ve shared a couple of tests that allow people to determine their philosophical/political leanings, including the libertarian/anarchist purity quiz, the circle test to see where you are on the spectrum from socialism to voluntarism, and a candidate affinity test.

I’m a sucker for these quizzes, even when they don’t make sense.

And if you like these tests (particularly one that does make sense), then you’ll enjoy this quiz from David Boaz’s new book, The Libertarian Mind: A Manifesto for Freedom.

You’ll be shocked to learn I got a perfect score. Which is probably a good thing since David is one of my bosses.

The Princess of the Levant will snicker at the thought of me being described as “cosmopolitan,” but I’ll tell her that even a rube can have a cosmopolitan vision of society.

And remember, libertarians also have the self confidence to enjoy self-deprecating humor, so we must be good folks.
