There’s been a bit of chatter in the blogosphere about a recent post on Ezra Klein’s blog featuring estimates from various economists about the revenue-maximizing tax rate. It won’t come as a surprise that people on the right tended to give lower estimates and folks on the left had higher guesses. Donald Luskin of National Review estimated 19 percent, for instance, while Emmanuel Saez, Dean Baker, Bruce Bartlett, and Brad DeLong all gave answers around 70 percent.
There are two things that are worth noting.
First, every single answer is to the right of the Joint Committee on Taxation. The revenue-estimators on Capitol Hill assume that taxes have no impact on overall economic performance. As such, even confiscatory tax rates have very little impact on taxable income. The JCT operates in a totally non-transparent fashion, so it is difficult to know whether they would say the revenue-maximizing tax rate is 90 percent, 95 percent, or 100 percent, but it is remarkable that a mini-bureaucracy with so much power is so far out of the mainstream (it’s even more remarkable that Republicans controlled Congress for 12 years, yet never fixed this problem, but that’s a separate story).
Second, very few of the respondents made the critically important observation that it should not be the goal of tax policy to maximize revenue. After all, the revenue-maximizing point is where the damage to the overall economy is so great that taxable income falls enough to offset the impact of the higher tax rates. Greg Mankiw of Harvard and Steve Moore of the Wall Street Journal indicated they understood this point since they both explained that the long-run revenue-maximizing rate was lower than the short-run revenue-maximizing rate. But Martin Feldstein of Harvard explicitly addressed this issue and hit the nail on the head.
Why look for the rate that maximizes revenue? As the tax rate rises, the “deadweight loss” (real loss to the economy rises) so as the rate gets close to maximizing revenue the loss to the economy exceeds the gain in revenue…. I dislike budget deficits as much as anyone else. But would I really want to give up say $1 billion of GDP in order to reduce the deficit by $100 million? No. National income is a goal in itself. That is what drives consumption and our standard of living.
For more information, I think my three-part video series on the Laffer Curve is a good summary of the key issues. Part I addresses the theory, and explicitly notes that policy makers should target the growth-maximizing tax rate rather than the revenue-maximizing tax rate. Part II reviews some of the evidence, including analysis of the huge increase in taxable income and tax revenue from upper-income taxpayers following the Reagan tax-rate reductions. Part III looks at the Joint Committee on Taxation’s dismal performance.
What about the long term? Is it possible that long after raising the tax rate, the resulting decreased growth rate will eventually lead to the government getting less revenue than it would have otherwise?
Some back-of-the-cocktail-napkin amateur analysis here, with made-up data:

The very short term Laffer Curve:
I’m sure that the revenue maximizing tax rate for tomorrow is over 90%. If you start taxing me at 95%, I’ll still go to work tomorrow. The day after tomorrow? less likely. A year from now? Definitely not! Especially if you start providing me with “free” heatlthcare, “free” education, “free” transportation, “free” recreation and “free” retirement, paid by the suckers who keep working.

Short tem vs. long term Laffer Curve:
Suppose there are two economies with otherwise equal per capita income. One decides to start operating at the top of the Laffer curve (ie. tax revenue maximization in the short term) and as a result of the blunted incentives to produce, its economy grows at 2% per year. The other operates at a tax revenue level of, say, 30% below the Laffer peak and as result its economy grows at 4%. After 10-20 years, in absolute terms, which economy collects more tax revenue?
But in some upside down economics world, where 2-5=8, many claim that if the government not only collects the maximum possible tax but also uses the revenue to impose economic inefficiency (by, say, mandating that people start using expensive energy) then some magical multiplier kicks in, which somehow leads to widespread prosperity. That seems to be the Grugmanesque perpetual motion machine of prosperity. How can anyone take economists seriously?

Of course the goal is not to maximize revenue. To the liberal, the goal is to redistribute wealth. So suppose initially person A makes $100,000 and person B makes $30,000. A tax takes $10,000 from A and gives it to B, but in the process reduces total wealth by 10%. (Assume $0 is lost to overhead.) Then A ends up with $80,000 and B ends up with $37,000. Their incomes are now closer together: The tax is a success. What if the tax is so disruptive that it reduces total wealth by 50%? Then A ends up with $40,000 and B with $25,000. Their incomes are now even closer together: the tax is an outstanding success. Sure, the poor person is worse off than he was before. But the rich person was harmed by more than the poor person, so the tax has achieved its objection of equalizing wealth.
