In some cases, politicians actually understand the economics of tax policy.

It’s quite common, for instance, to hear them urging higher taxes on tobacco because they want to discourage smoking.

I don’t think it’s their job to tell people how to live their lives, but I agree with their economic analysis. The more you tax something, the less you get of it.

One of my many frustrations is that those politicians then conveniently forget that lesson when it comes to taxing things that are good, such as work, saving, production, and investment.

And some countries are more punitive than others. There’s some new research from the European Policy Information Center, Timbro, and the Tax Foundation, that estimates the “effective marginal tax rate” for successful taxpayers for 41 major countries.

And they don’t simply look at the top income tax rates. They quite properly include other taxes that contribute to “deadweight loss” by driving a wedge between pre-tax income and post-tax consumption.

The political discussion around taxing high-earners usually revolves around the income tax, but in order to get a complete picture of the tax burden high-income earners face, it is important to consider effective marginal tax rates. The effective marginal tax rate answers the question, “If a worker gets a raise such that the total cost to the employer increases by one dollar, how much of that is appropriated by the government in the form of income tax, social security contributions, and consumption taxes?” …all taxes that affect the return to work should be taken into account. …Combining data mainly from international accounting firms, the OECD, and the European Commission, we are able to calculate marginal tax rates in the 41 members of the OECD and/or EU.

The main message of this research is that you don’t want to live in Sweden, where you only keep 24 percent of any additional income you produce.

And you should also avoid Slovenia, Belgium, Portugal, Finland, France, etc.

Congratulations to Bulgaria for being the anti-class warfare nation. That’s a smart strategy for a nation trying to recover from decades of communist deprivation.

American readers will be happy to see that the United States looks reasonably good, though New Zealand is the best of the rich nations, followed by Switzerland.

Speaking of which, we need a caveat for nations with federalist systems, such as the U.S., Switzerland, and Canada. In these cases, the top income tax rate is calculated by adding the central government’s top rate with the average top rate for sub-national governments.

So successful entrepreneurs in those countries actually have the ability to reduce their tax burdens if they make wise decisions on where to live (such as Texas or Florida in the case of the United States).

Let’s now shift to some economic analysis. The report makes (what should be) an obvious point that high tax rates have negative economic effects.

Countries should be cautious about placing excessive tax burdens on high-income earners, for several reasons. In the short run, high marginal tax rates induce tax avoidance and tax evasion, and can cause high-income earners to reduce their work effort or hours.

I would add another adverse consequence. Successful taxpayers can move.

That’s especially true in Europe, where cross-border tax migration is much easier than it is in the United States.

But even though there are odious exit taxes for people leaving the United States, we’ll see an exodus if we wind up with some of the crazy tax policies being advocated by Bernie Sanders and Elizabeth Warren.

P.S. Today’s column looks at how nations rank based on the taxation of labor income. For taxation of capital income, the rankings look quite different. For instance, because of pervasive double taxation, the United States gets poor scores for over-taxing dividends, capital gains, and businesses.

P.P.S. If you want to see tax rates on middle-income workers (though it omits value-added taxes), here is some OECD data.

California is suffering a slow but steady decline.

Bad economic policy has made the Golden State less attractive for entrepreneurs, investors, and business owners.

Punitive tax laws deserve much of the blame, particularly the 2012 decision to impose a top tax rate of 13.3 percent.

I’ve already shared some anecdotal evidence that this tax increase backfired.

But now we have some scholarly evidence from two Stanford Professors. Here’s what they investigated.

In this paper we study the question of the elasticity of the tax base with respect to taxation using microdata from the California Franchise Tax Board on the universe of California taxpayers around the implementation of Proposition 30 in 2012. This ballot initiative increased marginal income tax rates… These increases came on top of the 9.3% rate that applied to income over $48,942 for singles and $97,884 for married couples, and also in addition to the 1% mental health tax that since 2004 had applied to incomes of over $1 million. The reform therefore brought the top marginal tax rate in California to 13.3% for incomes of over $1 million.

For those not familiar with economic jargon, “elasticity” is simply a term to describe how sensitive taxpayers are when there are changes in tax policy.

A high measure of elasticity means a large “deadweight loss” since taxpayers are choosing to earn and/or report less income.

And that’s what the two scholars discovered.

Some high-income taxpayers responded to the big tax increase by moving.

We first study the extensive margin response to taxation, and document a substantial one-time outflow of high-earning taxpayers from California in response to Proposition 30. Defining a departure as a taxpayer who went from resident to non-resident filing status, the rate of departures in 2013 over 2012 spiked from 1.5% after the 2011 tax year to 2.125% for those primary taxpayers earning over $5 million in 2012, with a similar effect among taxpayers earning $2-5 million in 2012.

By the way, you won’t be surprised to learn that California taxpayers increasingly opted to move to states with no income tax, such as Florida, Nevada, and Texas.

Other taxpayers stayed in California but they chose to earn and/or report less income.

We combine these results on the extensive margin behavioral response with conclusions of analysis of the intensive margin response to Proposition 30. …we use a differences-in-differences design in which we compare upper-income California resident taxpayers to a matched sample of non-resident California filers, for which there is relatively rich data… Our estimates show a substantial intensive margin response to Proposition 30, which appears in 2012 and persists… We find that California top-earners on average report $522,000 less in taxable income than their counterfactuals in 2012, $357,000 less in 2013, and $599,000 less in 2014; this is relative to a baseline mean income of $4.15 million amongst our defined group of California top-earners in 2011. …the estimates imply an elasticity of taxable income with respect to the marginal net of tax rate of 2.5-3.3.

In the world of public finance, that’s a very high measure of elasticity.

Wonky readers may be interested in these charts showing changes in income.

By the way, guess what happens when taxpayers move, or when they decide to earn less income?

The obvious answer is that politicians don’t collect as much revenue. Which is exactly what the study discovered.

A back of the envelope calculation based on our econometric estimates finds that the intensive and extensive margin responses to taxation combined to undo 45.2% of the revenue gains from taxation that otherwise would have accrued to California in the absence of behavioral responses. The intensive margin accounts for the majority of this effect, but the extensive margin comprises a non-trivial 9.5% of this total response.

We can call this the revenge of the Laffer Curve.

By the way, it’s quite likely that there has been a resurgence of both the “extensive” and “intensive” responses to California’s punitive tax regime because the 2017 tax reform restricted the deductibility of state and local taxes. This means that the federal government – for all intents and purposes – is no longer subsidizing California’s backwards fiscal system.

P.S. Makes me wonder if California politicians will turn Walter Williams’ joke into reality.

In addition to being a contest over expanding the burden of government spending, the Democratic primary also is a contest to see who wants the biggest tax increases.

Bernie Sanders and Elizabeth Warren have made class-warfare taxation an integral part of their campaigns, but even some of the supposedly reasonable Democrats are pushing big increases in tax rates.

James Pethokoukis of the American Enterprise Institute opines about the anti-growth effect of these proposed tax hikes, particularly with regard to entrepreneurship and successful new firms.

The Democratic presidential candidates have plenty of ideas about taxes. Wealth taxes. Wall Street taxes. Inequality taxes. And probably more to come. So lots of creative thinking about wealth redistribution. Wealth creation? Not so much. …one way to look at boosting GDP growth is thinking about specific policies to boost labor force and productivity growth. But there’s another way of approaching the issue: How many fast-growing growing new firms would need to be generated each year to lift the economy-wide growth rate each year by one percent? …a rough calculation by analyst Robert Litan figures there about 15 billion-dollar (in sales) companies formed every year. But what if the American entrepreneurial ecosystem were so vibrant that it produced 60 such companies annually? …The big point here is that the American private sector is key to growth. No other large economy is as proficient as the US in creating high-impact startups. But it doesn’t appear that the Democratic enthusiasm for big and bold tax plans is matched by concern about unwanted trade-offs.

If you want a substantive economic critique of class-warfare tax policy, Alan Reynolds has a must-read article on the topic.

He starts by explaining why it’s important to measure how sensitive taxpayers are (the “elasticity of taxable income”) to changes in tax rates.

Elasticity of taxable income estimates are simply a relatively new summary statistic used to illustrate observed behavioral responses to past variations in marginal tax rates. They do so by examining what happened to the amount of income reported on individual tax returns, in total and at different levels of income, before and after major tax changes. …For example, if a reduced marginal tax rate produces a substantial increase in the amount of taxable income reported to the IRS, the elasticity of taxable income is high. If not, the elasticity is low. ETI incorporates effects of tax avoidance as well as effects on incentives for productive activity such as work effort, research, new business start-ups, and investment in physical and human capital.

Alan then looks at some of the ETI estimates and what they imply for tax rates, though he notes that the revenue-maximizing rate is not the optimal rate.

Diamond and Saez claim that, if the relevant ETI is 0.25, then the revenue-maximizing top tax rate is 73 percent. Such estimates, however, do not refer to the top federal income tax rate, …but to the combined marginal rate on income, payrolls, and sales at the federal, state, and local level. …with empirically credible changes in parameters, the Diamond-Saez formula can more easily be used to show that top U.S. federal, state, and local tax rates are already too high rather than too low. By also incorporating dynamic effects — such as incentives to invest in human capital and new ideas — more recent models estimate that the long-term revenue-maximizing top tax rate is between 22 and 49 percent… Elasticity of taxable, or perhaps gross income…can be “a sufficient statistic to approximate the deadweight loss” from tax disincentives and distortions. Although recent studies define revenue-maximization as “optimal,” Goolsbee…rightly emphasizes, “The fact that efficiency costs rise with the square of the tax rate are likely to make the optimal rate well below the revenue-maximizing rate.”

These excerpts only scratch the surface.

Alan’s article extensively discusses how high-income taxpayers are especially sensitive to high tax rates, in part because they have considerable control over the timing, level, and composition of their income.

He also reviews the empirical evidence from major shifts in tax rates last century.

All told, his article is a devastating take-down of the left-of-center economists who have tried to justify extortionary tax rates. Simply stated, high tax rates hinder the economy, create deadweight loss, and don’t produce revenue windfalls.

That being said, I wonder whether his article will have any impact. As Kevin Williamson points out is a column for National Review, the left isn’t primarily motivated by a desire for more tax money.

Perhaps the strangest utterance of Barack Obama’s career in public office…was his 2008 claim that raising taxes on the wealthy is a moral imperative, even if the tax increase in question ended up reducing overall federal revenue. Which is to say, Obama argued that it did not matter whether a tax increase hurt the Treasury, so long as it also hurt, at least in theory and on paper, certain wealthy people. …ideally, you want a tax system with low transaction costs (meaning a low cost of compliance) and one that doesn’t distort a lot of economic activity. You want to get enough money to fund your government programs with as little disruption to life as possible. …Punitive taxes aren’t about the taxes — they’re about the punishment. That taxation should have been converted from a technical question into a moral crusade speaks to the basic failure of the progressive enterprise in the United States…the progressive demand for a Scandinavian welfare state at no cost to anybody they care about…ends up being a very difficult equation to balance, probably an impossible one. And when the numbers don’t work, there’s always cheap moralistic histrionics.

So what leads our friends on the left to pursue such misguided policies? What drives their support for punitive taxation?

Is is that they’re overflowing with compassion and concern for the poor?

Hardly.

Writing for the Federalist, Emily Ekins shares some in-depth polling data that discovers that envy is the real motive.

Supporters often contend their motivation is compassion for the dispossessed… In a new study, I examine…competing explanations and ask whether envy and resentment of the successful or compassion for the needy better explain support for socialism, raising taxes on the rich, redistribution, and the like. …Statistical tests reveal resentment of the successful has about twice the effect of compassion in predicting support for increasing top marginal tax rates, wealth redistribution, hostility to capitalism, and believing billionaires should not exist. …people who agree that “very successful people sometimes need to be brought down a peg or two even if they’ve done nothing wrong” were more likely to want to raise taxes on the rich than people who agree that “I suffer from others’ sorrows.” …I ran another series of statistical tests to investigate the motivations behind the following beliefs: 1) It’s immoral for our system to allow the creation of billionaires, 2) billionaires threaten democracy, and 3) the distribution of wealth in the United States is “unjust.” Again, the statistical tests find that resentment against successful people is more influential than compassion in predicting each of these three beliefs. In fact, not only is resentment more impactful, but compassionate people are significantly less likely to agree that it’s immoral for our system to allow people to become billionaires.

Here’s one of her charts, showing that resentment is far and away the biggest driver of support for class-warfare proposals.

These numbers are quite depressing.

They suggest that no amount of factual analysis or hard data will have any effect on the debate.

And there is polling data to back up Emily’s statistical analysis. Heck, some folks on the left openly assert that envy should be the basis for tax policy.

In other words, Deroy Murdock and Margaret Thatcher weren’t creating imaginary enemies.

P.S. If you think Kevin Williamson was somehow mischaracterizing or exaggerating Obama’s spiteful position on tax policy, just watch this video.

The New York Times is going overboard with disingenuous columns.

A few days ago, I pointed out the many errors in David Leonhardt’s column extolling the wealth tax.

I also explained back in August how Steven Greenhouse butchered the data when he condemned the American economy.

And Paul Krugman is infamous for his creative writing.

But Mr. Leonhardt is on a roll. He has a new column promoting class warfare tax policy.

Almost a decade ago, Warren Buffett made a claim that would become famous. He said that he paid a lower tax rate than his secretary, thanks to the many loopholes and deductions that benefit the wealthy.oct-8-19-nyt …“Is it the norm?” the fact-checking outfit Politifact asked. “No.” Time for an update: It’s the norm now. …the 400 wealthiest Americans last year paid a lower total tax rate — spanning federal, state and local taxes — than any other income group, according to newly released data. …That’s a sharp change from the 1950s and 1960s, when the wealthy paid vastly higher tax rates than the middle class or poor.

Here’s the supposed proof for Leonhardt’s claim, which is based on a new book from two professors at the University of California at Berkeley, Emmanuel Saez and Gabriel Zucman.

Here are the tax rates from 1950.

oct-8-19-1950

And here are the tax rates from last year, showing the combined effect of the Kennedy tax cut, the Reagan tax cuts, the Bush tax cuts, and the Trump tax cut (as well as the Nixon tax increase, the Clinton tax increase, and the Obama tax increase).

oct-8-19-2018

So is Leonhardt (channeling Saez and Zucman) correct?

Are these charts evidence of a horrid and unfair system?

Nope, not in the slightest.

But this data is evidence of dodgy analysis by Leonhardt and the people he cites.

First and foremost, the charts conveniently omit the fact that dividends and capital gains earned by high-income taxpayers also are subject to the corporate income tax.

Even the left-leaning Organization for Economic Cooperation and Development acknowledges that both layers of tax should be included when measuring the effective tax rate on households.

Indeed, this is why Warren Buffett was grossly wrong when claiming he paid a lower tax rate than his secretary.

But there’s also another big problem. There’s a huge difference between high tax rates and high tax revenues.

feb-4-19-perrySimply stated, the rich didn’t pay a lot of tax when rates were extortionary because they can choose not to earn and declare much income.

Indeed, there were only eight taxpayers in 1960 who paid the top tax rates of 91 percent.

Today, by contrast, upper-income taxpayers are paying an overwhelming share of the tax burden.

It’s especially worth noting that tax collections from the rich skyrocketed when Reagan slashed the top tax rate in the 1980s.

Let’s close by pointing out that Saez and Zucman are promoting a very radical tax agenda.

Saez and Zucman sketch out a modern progressive tax code. The overall tax rate on the richest 1 percent would roughly double, to about 60 percent. The tax increases would bring in about $750 billion a year, or 4 percent of G.D.P…. One crucial part of the agenda is a minimum global corporate tax of at least 25 percent. …Saez and Zucman also favor a wealth tax

Punitive income tax rates, higher corporate tax rates, and a confiscatory wealth tax.

Does anybody think copying France is a recipe for success?

P.S. I pointed out that Zucman and Saez make some untenable assumptions when trying to justify how a wealth tax won’t hurt the economy.

P.P.S. It’s also worth remembering that the income of rich taxpayers will be subject to the death tax as well, which means Leonhardt’s charts are doubly misleading.

At the risk of over-simplifying, the difference between “supply-side economics” and “demand-side economics” is that the former is based on microeconomics (incentives, price theory) while the latter is based on macroeconomics (aggregate demand, Keynesianism).

When discussing the incentive-driven supply-side approach, I often focus on two key points.

  • Marginal tax rates matter more than average tax rates because the incentive to earn additional income (rather than enjoying leisure) is determined by whether the government grabs a small, medium, or large share of any extra earnings.
  • Some taxpayers such as investors, entrepreneurs, and business owners are especially sensitive to changes in marginal tax rates because they have considerable control over the timing, level, and composition of their income.

Today, let’s review some new research from Spain’s central bank confirms these supply-side insights.

Here’s what the authors investigated.

The impact of personal income taxes on the economic decisions of individuals is a key empirical question with important implications for the optimal design of tax policy. …the modern public finance literature has devoted significant efforts to study behavioral responses to changes in taxes on reported taxable income… Most of this work focuses on the elasticity of taxable income (ETI), which captures a broad set of real and reporting behavioral responses to taxation. Indeed, reported taxable income reflects not only individuals’ decisions on hours worked, but also work effort and career choices as well as the results of investment and entrepreneurship activities. Besides these real responses, the ETI also captures tax evasion and avoidance decisions of individuals to reduce their tax bill.

By the way, “elasticity” is econ-speak for sensitivity. In other words, if there’s high elasticity, it means taxpayers are very responsive to a change in tax rates.

Anyhow, here’s how authors designed their study.

In this paper, we estimate the elasticity of taxable income in Spain, an interesting country to study because during the last two decades it has implemented several major personal income tax reforms… In the empirical analysis, we use an administrative panel dataset of income tax returns… We calculate the MTR as a weighted average of the MTR applicable to each income source (labor, financial capital, real-estate capital, business income and capital gains).

You can see in Figure 1 that the 2003 reform was good for taxpayers and the 2012 reform was bad for taxpayers.

If nothing else, though, these changes created the opportunity for scholars to measure how taxpayers respond.

And here are the results.

We obtain estimates of the ETI around 0.35 using the Gruberand Saez (2002) estimation method, 0.54 using Kleven and Schultz (2014)’s method and 0.64 using Weber (2014)’s method. …In addition to the average estimates of the ETI, we analyze heterogeneous responses across groups of taxpayers and sources of income. …As expected, stronger responses are documented for groups of taxpayers with higher ability to respond. In particular, self-employed taxpayers have a higher ETI than wage employees, while real-estate capital and business income respond more strongly than labor income. …we find large responses on the tax deductions margin, especially private pension contributions.

In other words, taxpayers do respond to changes in tax policy.

And some taxpayers are very sensitive (high elasticity) to those changes.

Here’s Table 6 from the study. Much of it will be incomprehensible if you’re not familiar with econometrics. But all that matters is that I circled (in red) the measures of how elasticities vary based on the type of income (larger numbers mean more sensitive).

I’ll close with a very relevant observation about American fiscal policy.

Currently, upper-income taxpayers finance the vast majority of America’s medium-sized welfare state.

But what if the United States had a large-sized welfare state, like the ones that burden many European nations?

If you review the data, those large-sized welfare states are financed with stifling tax burdens on lower-income and middle-class taxpayers. Politicians in Europe learned that they couldn’t squeeze enough money out of the rich (in large part because of high elasticities).

Indeed, I wrote early this year about how taxes are confiscating the lion’s share of the income earned by ordinary workers in Spain.

And if we adopt the expanded welfare state envisioned by Bernie Sanders, Alexandria Ocasio-Cortez, and Kamala Harris, the same thing will happen to American workers.

P.S. I admire how Spanish taxpayers have figured out ways of escaping the tax net.

P.P.S. There’s also evidence about the impact of Spain’s corporate tax.

Assuming the goal is faster growth and higher living standards, there are three core principles of good tax policy.

You could call this list the Holy Trinity of supply-side economics. Simply stated, incentives matter, so it makes no sense for government to discourage the things that make a nation more prosperous.

Regarding low marginal tax rates, my left-leaning friends sometimes dismiss the importance of this principle by pointing out that they don’t pay much attention to their marginal tax rates.

I can sympathize with their skepticism. When I was first learning about public finance and studying supply-and-demand curves showing deadweight loss, I also wondered about the supply-side claim that marginal tax rates mattered. Even after I started working, I had doubts. Would I somehow work harder if my tax rate fell? Or goof off if my tax rate went up? It didn’t make much sense.

What I didn’t recognize, however, is that I was looking at the issue from the perspective of someone working a standard, 9-to-5 job with a modest income. And it is true that such workers are not very responsive (especially in the short run) to changes in tax rates.

In the real world, though, there are lots of people who don’t fit that profile. They have jobs that give them substantial control over the timing, level, and composition of their income.

And these people – such as business owners, professionals, second earners, investors, and entrepreneurs – often are very responsive to changes in marginal tax rates.

We have a new example of this phenomenon. Check out these excerpts from a story in the U.K.-based Times.

About three quarters of GPs and hospital consultants have cut or are planning to cut their hours… About 42 per cent of family doctors and 30 per cent of consultants have reduced their working times already, claiming that they are being financially penalised the more they work. A further 34 per cent and 40 per cent respectively have confirmed that they plan to reduce their hours in the coming months… The government has launched an urgent consultation over the issue, which is the result of changes to pension rules limiting the amount that those earning £110,000 or more can pay into their pensions before they are hit with a large tax bill.

In other words, high tax rates have made leisure more attractive than work. Why work long hours, after all, if the tax authority is the biggest beneficiary?

There are also indirect victims of these high tax rates.

Last month figures from NHS Providers, which represents hospitals, showed that waiting lists had climbed by up to 50 per cent since April as doctors stopped taking on extra shifts to avoid the financial penalties. Richard Vautrey, chairman of the BMA GPs’ committee, said: “These results show the extent to which GPs are being forced to reduce their hours or indeed leave the profession altogether because of pension taxes. …swift and decisive action is needed from the government to end this shambolic situation and to limit the damage that a punitive pensions taxation system is inflicting on doctors, their patients and across the NHS as a whole.”

The U.K.’s government-run health system already has plenty of problems, including long wait times and denial of care. The last thing it needs is for doctors and other professionals to cut back their hours because politicians are too greedy.

The moral of the story is that tax rates matter. Depending on the type of person, they can matter a lot.

This doesn’t mean tax rates need to be zero (though I like that idea).

It simply means that taxes impose costs, and those costs become increasingly apparent as tax rates climb.

Yesterday’s column weighed in on the debate whether Jesus was a socialist.

Like Cal Thomas, I don’t think the Bible supports coercive redistribution by government.

Today, let’s look at the same issue, but from a humorous perspective.

For those on the other side of the debate, Socialist Jesus has a very efficient mechanism to collect alms for the poor.

This approach is supported by some parishoners.

From Babylon Bee, we have a story about a disciple of Socialist Jesus.

A lot of Christians are criticized for not being very compassionate to the poor. But you can’t say that about Larry DeManson, a local believer who is so committed to charity for those less fortunate than himself that he always votes for government to steal money from his neighbor and give it to the impoverished. …DeManson no longer has a guilty conscience whenever he sees people in need. “I don’t personally have to do anything,” he said. “The government does it for me.” The man cites the verse “somewhere in James” that says that “true religion before the Father is to forcibly redistribute money from those wealthier than you in order to take care of the poor.”

Now let’s look at an alternative approach.

Except we won’t be sharing insights from Libertarian Jesus.

Instead, courtesy of Imgur, we have the story of Supply-Side Jesus.

And this Supply-Side Jesus is an advocate of trickle-down economics.

He creates lots of jobs.

And he believes in self-sufficiency.

He also opposes class warfare.

Supply-Side Jesus is a fan of the entrepreneur class.

And he understands self-promotion.

But not everyone is happy.

Supply-Side Jesus was in trouble.

But he avoided trouble, thanks to majoritarianism.

Supply-Side Jesus then decided to enter politics.

I don’t know who created this cartoon strip, but kudos for some clever humor (though I imagine practitioners of the “Prosperity Gospel” won’t be amused).

As a general rule, I find that leftists are too dour to create effective political humor (see the Black NRA, for instance). But when they come up with something clever (see here, here, and here), I’m more than willing to applaud.

Even when they mock libertarians!
