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.

New Academic Research Confirms the ‘High Price’ of High Tax Rates

I periodically cite new academic research about tax policy and economic activity. I sometimes even publicize research from international bureaucracies showing the link between taxes and growth.

I’m not naive enough to think that any particular study will change minds, but when the bulk of the research unambiguously tells us that lower tax rates are better for economic performance, I think (or at least hope) that it may have some impact on government officials.

That’s why I’m particularly interested in some new research by Cornell University’s Karel Mertens.

Here are some key findings from Mertens’ study, beginning with some observations on existing research.

To what extent do marginal tax rates matter for individual decisions to work and invest? The answer is essential for public policy and its role in shaping economic growth. The strand of the empirical literature that uses tax return data, surveyed in Saez, Slemrod and Giertz (2012), finds that incomes before taxes react only modestly to marginal tax rates and that the response is mostly situated at the very top of the income distribution.

So what does this mean? A lot depends on how one defines “modestly,” though it’s worth noting that even very small changes in growth—if sustained over time—can have big impacts on prosperity. That, in turn, has a significant effect on government finances.

And I have no objection to the assertion that upper-income taxpayers are most sensitive to changes in tax rates. After all, people like me who rely on wage and salary income don’t have much opportunity to alter our compensation in response to changes in tax rates.

But upper-income taxpayers get most of their compensation in the form of business profits and investment returns, and this gives them substantial control over the timing, level, and composition of their income. So it’s quite understandable that their taxable income is quite sensitive to changes in tax rates.

New European Data: When Tax Competition Is Weakened, Politicians Respond by Increasing Tax Rates

I often argue that we need to preserve tax competition and tax havens in order to limit the greed of the political class.

Without some sort of external constraint, they will over-tax and over-spend, creating the kind of downward economic spiral already happening in some European nations.

Speaking of which, new evidence from Europe bolsters my case.

Back in 2009, facing pressure from the big G-20 nations, all of the world’s major low-tax jurisdictions - even Switzerland - acquiesced to the notion that human rights laws protecting financial privacy no longer would apply to foreign investors.

In other words, high-tax governments now have much greater ability to track - and tax - flight capital.

So how have they responded since that time? Well, look at this chart from the European Union’s new report on taxation trends. Tax rates have begun to increase, reversing a very positive trend (which began with the Reagan and Thatcher tax cuts, though this chart only shows data since 1995).

Dissecting Obama’s Record on Tax Policy

The folks at the Center for Freedom and Prosperity have been on a roll in the past few months, putting out an excellent series of videos on Obama’s economic policies.

Now we have a new addition to the list. Here’s Mattie Duppler of Americans for Tax Reform, narrating a video that eviscerates the President’s tax agenda.

I like the entire video, as you can imagine, but certain insights and observations are particularly appealing.

1. The rich already pay a disproportionate share of the total tax burden - The video explains that the top-20 percent of income earners pay more than 67 percent of all federal taxes even though they earn only about 50 percent of total income. And, as I’ve explained, it would be very difficult to squeeze that much more money from them.

2. There aren’t enough rich people to fund big government - The video explains that stealing every penny from every millionaire would run the federal government for only three months. And it also makes the very wise observation that this would be a one-time bit of pillaging since rich people would quickly learn not to earn and report so much income. We learned in the 1980s that the best way to soak the rich is by putting a stop to confiscatory tax rates.

3. The high cost of the death tax - I don’t like double taxation, but the death tax is usually triple taxation and that makes a bad tax even worse. Especially since the tax causes the liquidation of private capital, thus putting downward pressure on wages. And even though the tax doesn’t collect much revenue, it probably does result in some upward pressure on government spending, thus augmenting the damage.

4. High taxes on the rich are a precursor to higher taxes on everyone else - This is a point I have made on several occasions, including just yesterday. I’m particularly concerned that the politicians in Washington will boost income tax rates for everybody, then decide that even more money is needed and impose a value-added tax.

The video also makes good points about double taxation, class warfare, and the Laffer Curve.
