Where are we on the Laffer Curve?
For the U.S., that is.
Some people say we must raise taxes in order for the federal government to increase revenue. But will raising taxes automatically increase revenue? Based on where we are on the Laffer Curve, isn't there a real possibility that higher taxes could actually decrease revenue to the government? I guess it all depends on "where we are" on the Laffer Curve. So where are we? |

Even assuming the curve was correct (and I doubt very many people believe in it any more), it's impossible to tell.

Still compared to other OECD countries, you seem to have lower rates, it would appear that you have quite enough margin for raising taxes over a period to pay down debt, and there would also taking comparative examples, be little reason to fear 'reduced revenue.' Perhaps over more than a decade... but in any case, debt reduction has to come from increased revenues. Same thing the Greeks are learning right now. ETA: I realise the US has a federalised tax system and the states have great leeway in taxing, so making US to say more centralised taxation system comparisons can be very difficult.

I think we are at the point of declining returns (it is more profitable to evade taxation now). That is why we see guys like George Soros setting up operations in tax havens (like certain west indies islands) to avoid federal taxes.
I see the "underground' economy growing by leaps and bounds-my mechanic offered to do some work on my car for me: the price (cash, no receipt) was $60.00-if I paid via credit card, it would be $100.00. |

This appears (to me) to illustrate that the soct of evasion is now less than the cost of compliance.

Regardless, 40% puts you in the average area of OECD country headline taxation rates, including countries with apparently low levels of evasion. Thus empirically we can't merely assert that level is on the declining end of a Laffer Curve type analysis. I suppose culturally it might be, but equally it might not. One rather suspects your mechanic will evade at any and all levels of taxation (as he is so small that the likelihood of being caught and punished is doubtless trivial), and ergo is not an argument under a Laffer curve type analysis for any particular level. This person will always make more money in dodging taxes (although one supposes in dodging his retirement contributions he's cheating himself in reality, but I am not familiar enough with that system). There will always be economic actors who will dodge taxes regardless of their level (while doubtless always engaging in rationalisations along the way). You also did not answer my question about change in tax rates. I do believe on this type of person I read the tax rate went down, correct? Quote:

Is is astonishing how Fox News and the tea party movement have convinced people that Obama raised their taxes, when in reality he actually lowered them. While it's true that **starting in 2 years**, taxes will be raised on the richest 2% of america, to date federal taxes haven't gone up a dime for even one single person; and in fact, have actually gone *down* for most americans over the past year. But for some reason, most people seem to not understand that.

Ask yourself -- you already have a job working 40,50,60 or however many hours a week. Now suppose your taxes were cut 10%. Would you then go out and get a second job? Would you start working more hours at work than you already do? No? Honestly, the vast majority of people would not. What about the other way around? Suppose someone raised your taxes 10%. Would you quit your job then? No? Well, since the alternative to working is to starve, then most people wouldn't do that either. So if raising and lowering the tax rate +/- 10% really won't affect most people's decision to work or not, then doesn't that count as some pretty serious evidence against the Laffer Curve?

Look, the Laffer curve has some use as an illustrative model, but not as a predictive one.
But to ralph124c's point, his mechanic isn't paying 40% taxes. For one thing, his state income tax is deductible from his federal taxes, and what's more, that 20% (notional) tax bracket does not apply to all income. According to the CBO, not even the richest one percent of Americans have an effective Federal income tax rate of 20%. (see page 4) Odds are pretty good that the amount of his paycheck that he's actually paying in Federal income taxes is somewhere around 6-12% -- which is a more accurate measure of taxation than just throwing around tax bracket numbers. |

What's the equation for the Laffer Curve, anyway?
|
|
#18
|
|||
|

It's not an equation, per se. It's just a parabola with two positive roots at 0 and 100, a 0 y-intercept, and a maximum somewhere between 0 and 100. It's not a mathematical formula, just a picture you can point at and say "if you're here, and raise taxes, you'll lose revenue."
If you wanted to approximate it, one way would be to look at the places where the revenue (which I'll call f(x)) is 0 (x = 0, x = 100), and multiply it out: f(x) = (x - 100)*(-x - 0) = -x2 - 100x, which gives you the correct roots; a maximum at x = 50 (f'(x) = -2x - 100 = 0); and the correct concavity (f''(x) = -2x < 0 for strictly positive x). Still, that's reasoning out from the properties we want to the function, not starting with the formula and finding useful properties of it. Last edited by Ace309; 04-24-2010 at 03:31 PM. |

And in editing I failed to correct a functional mistake I made, which is that the function should be -x2 + 100x. That leads to the correct maximum at x = 50 (-2x + 100 = 0) and leaves the concavity untouched.

I think the point of the Laffer curve is to show that tax revenue will not necessarily increase as tax rates increase. It's just a way of saying "don't count your eggs before they hatch."
So, the Laffer Curve is a meaningful concept without knowing where we are on it (or even knowing how to determine where we are on it). |

My take on this, and I am admittedly far from knowledgeable in the field of economics, is that if someone is rich enough to have vast amounts of spare cash accumulating large interest rates, it is in the best interests of the state to encourage that money to go back into the economy. If that means "encouraging" them with 95% tax rates on all such profits, then so be it.

As to the implication that the distribution of taxes is not skewed toward those with higher incomes: In 2007 in the US, the top 5% earned about 35% of income and paid about 60% of all Federal Income tax. The top 1% earned about 20% of income and paid about 40% of Federal Income tax. The bottom 47% this past year paid no Federal income tax it all. I agree add that we have no mechanism , current or proposed, to tax wealth per se, but that hardly justifies promoting the idea that our taxes are low or that we do no preferentially tax those with higher incomes.

If you take a moment to review OECD analyses on income tax, the US does not come out at the top of the leagues. Indeed overall pay rate is near bottom. That is data.
Der Trihs being rather hard left of course views that as a bad thing. On the other hand, my impression is Americans are particularly tetchy about any tax paid at all. Quote:

For example, my income places me somewhere around the top 18, maybe 15% of earners in the country. Adding up the actual amount I pay, just a shade under 19% of my total salary goes to Federal and state income taxes. Unless someone is making a lot more money than me, has no mortgage, and takes the standard deduction, I have a hard time figuring out how people get to paying 40% of their income to income taxes. Let me make another point more on-topic to the OP: let's say the Laffer curve as illustrated was, in fact, ground truth on tax rates, in which the government gets no income at 0% or 100% taxation, and optimal taxation were somewhere in the 50% range. Again, according to my CBO citation, the current average burden of Federal taxation across all income groups is currently 20.7%, including income, payroll, corporate, and excise taxes. ETA: and below is a citation showing that the average state tax burden is about 10% of income. That would seem to indicate that we could nearly double taxation and have much more revenue coming in to the Treasury. http://www.taxfoundation.org/taxdata/show/335.html Last edited by Ravenman; 04-25-2010 at 08:23 AM. |

Just to provide another citation, here's a Forbes PDF from 2006 which shows that the total tax burden for Americans - including Federal, state and local taxes -- totaled to 25% in 2004. Link.
Again, it seems we could nearly double taxation if the Laffer curve as typically drawn were to be taken literally. |

Fair enough, although I would point out that many of the forms of extra-legal means require the use of an accountant (all the charity-based evasions I know of do). The point remains that if the cost of evasion is greater than the cost of paying the tax, it ceases to be profitable to evade the tax, legally or extra-legally.

Few economists take the Laffer curve very seriously (minimally there is no way to ever know where one actually is on the curve, or how the curve is actually shaped or if it shifts), at least not without some serious modifications, but perhaps the best way to answer the question of the op is to go to Laffer himself - he thinks

But wmfellows that as an answer presupposes that the curve has some validity to begin with, which is itself, at best, a matter of debate. OTOH it may be a valid answer to the question of "Is there any empirical basis to claims like those that Laffer currently makes that allowing some of the Bush era tax cuts for the rich expire, or for that matter even raising other taxes in America, would cause a decrease in total tax revenues collected rather than an increase? "
But then if one wants to go with empirical basis you can merely say that if Laffer says something it is more than likely wrong. Tax revenues did not increase during the Reagan era even as the economy rebounded. In 2006 he was cheerleading how the US economy "has never been in better shape", pretty much right before it collapsed. In 2008 he had changed his tune and was writing that the stock collapse was the start of a long term bear market, likely -6% per year for the next 16 years, and that "Twenty-five years down the line, what this administration and Congress have done will be viewed in much the same light as what Herbert Hoover did in the years 1929 through 1932. ... We are now witnessing the end of prosperity." And prosperity's end came not because of the failure of the Bush era supply side approach, or inadequate oversight by regulatory bodies, nope, it was because Congress and Bernanke "panicked". Of course the stock market subsequently rallied nicely. In mid-2009 he was writing that we are due for interest rates rises and inflation unlike anything we have ever seen before. So he's called it wrong every time so far. Heck, even Ben Stein, a conservative's conservative, saw that back in 2006. Quote:

The rest of your comment is very American politics specific and I would suspect argumentative on that basis, although if you wish to highlight that it is not empirically sensible to take that curve literally, and that it should be seen as a simplistic expression of diminishing returns and tax policy elasticity... well fair enough. I don't believe that this materially is terribly different than what I wrote, but of course I am not sensitive to the US politics in this area. |

But wmfellows it does mean that there is no empirical basis for any definable curve.
As a matter of abstract theory, yes, there is very likely some taxable income elasticity, and therefore some degree of diminishing returns. In the real world that depends on the presence of many other factors such as legal means to defer income or to avoid reporting it as fully (often referred to as "loopholes") and perceptions of what future changes may bring to both the tax code and to the economy. |

That number is still 21.3% of my gross. My taxes are 21.3% of all the money I saw in 2008. This includes money I paid to contractors, cost of goods sold, for equipment, etc. A lot of that money was not money that was mine to begin with. (For example, I have some associates that contract through me, and I keep $500 of a $2000 contract, but they get paid $1500. That entire $2000 is in my gross and part of the 21.3% number I'm giving you there.) That's still more than that 16.52% number Turbo Tax listed as my tax rate, and far more than the 6-12% number you've cited.

Chief Pedant, again Forbes places the US as way down the list on their "misery index", the amount that the highest wage earners have to pay. In this case DT is correct: America's tax burden on individuals (not corporations) is relatively low compared to the rest of the world, if not especially for the highest earners, then at least for them as well as for the average tax payer.
In fact Quote:
Quote:
Quartz, cutting taxes to stimulate the economy is one thing and that is basic Keynesian theory. The bit that doing so stimulates the economy so greatly as produce more tax revenues than is lost because of the cut has been shown to be false. Even the hold-outs at Cato no longer try to argue that point - they are reduced to trying to claim that the highest earners will reduce their taxable income to avoid paying taxes at "too high" of a rate and that will reduce tax revenues overall. But do you really think that high wage earners like CP works less because his top marginal rate is 35%? |
