The WSJ has been peddling the "supply side " economics laffer (laugher) curve nonsense for years. The "theory" argues that tax cuts generate so much new economic activity that the new tax revenues from such activity offset the initial loss in tax revenues. WSJ op ed page hack has gone as far as to assert on several occasions on CNBC that the tax cuts are "self financing" i.e. enough new tax revenue is generated to fully offset the iniital loss in tax revenues.
Reagan budget director David Stockman wrote
In The Triumph of Politics, :
- [T]he whole California gang had taken [the Laffer curve] literally (and primitively). The way they talked, they seemed to expect that once the supply-side tax cut was in effect, additional revenue would start to fall, manna-like, from the heavens. Since January, I had been explaining that there is no literal Laffer curve.
This morning the WSJ returns to this hackneyed line of "thought". But even they can only muster the most paltry of evidence and know state:
And no supply-sider we know -- and we know them all -- claims that all tax cuts pay for themselves on a dollar-for-dollar basis
I guess the WSJ editorial board hasn't met one of its own members - Stephen Moore, or at least doesn't know what he says on television....And read the above carefully. Bottom line tax cuts will add to the deficit indefinitely.
Cuts in marginal income tax rates, on the other hand, have demonstrated over the years that they have a big impact on investment and work decisions and thus recoup much of the revenue that "static" models estimate they will lose. Harvard's Martin Feldstein has done research calculating that marginal rate cuts yield back at least one-third of their projected revenue loss.
....And read the above carefully. Bottom line: tax cuts will add to the deficit indefinitely. There is no way the budger will be cut enough to offset 2/3 of the revenue loss from tax cuts. And note the current budget projections assume no changes in the AMT at the same time the administration is proposing limits on it.
So now we're down to 1/3 recovery of the projected income loss not 100% and given the source, let's just say it's on the optimistic side.
For a more down to earth view: (from wikipedia )links are to the original sources.
In 2005, the Congressional Budget Office released a paper called "Analyzing the Economic and Budgetary Effects of a 10 Percent Cut in Income Tax Rates" [2] that casts doubt on the idea that tax cuts ultimately improve the government's fiscal situation. Unlike earlier research, the CBO paper examines the budgetary impact of any possible macroeconomic effects of tax policies, i.e., it attempts to account for how tax cuts affect the overall size of the economy, and therefore influence future government tax revenues; and ultimately, deficits or surpluses. The paper's author forecasts the effects using various assumptions (e.g., people's foresight, the mobility of capital and the ways in which the federal government might make up for the lost revenue). Even in the paper's most generous scenario, only 28% of lost tax revenue is recouped over a 10-year period after a 10% tax-rate cut. The paper points out that these shortfalls in revenue would have to be made up by federal borrowing: the paper estimates that the federal government would pay an extra $200 billion in interest over the decade covered by his analysis. The 10% tax cut would result in a 1% increase in gross national product. The paper appears to focus on Federal government revenue only and does not look at the total public sector revenue (i.e., it does not include increases in local and state government revenue).
Remember, the additional debt never goes away, it just grows and compounds ,as does the cost of servicing it, eventually offsetting any increase in gnp as well. Think of maxing out all your credit cards, buying a new car and building an addition to your house. You've generated lots of economic activity in the short term but it all went into consumption. In the long term as the debt burden hits, you'll have to cut back economic activity to service the debt.
back to the WSJ:
He's also shown that such cuts have an especially large impact on the decisions of household second-earners, typically women, to enter the workplace. A 50% marginal tax rate on the next dollar of income -- the combined state and federal burden in such high-tax states as New York and California -- reduces greatly the incentive for a spouse to trade staying home for a 40-hour week.
On this one, let's just say attributing causation to a single factor in economic research is not easy. If Professor Feldstein is studying the impact of the 2001 cuts, I might speculate that some of those new household secon earners (re)entering the workforce might be a function of the decline in real wages by workers over the period since 2001 (actually earlier). I'll try to track down the actual research.
and here's one that clearly demonstrates that the WSJ op ed folks must not read the rest of the newspaper:
Cuts in capital gains tax rates have had an even larger revenue payback over the years, because they raise the after-tax return on capital and because of the incentive they give investors to lock in a profit by selling stocks and thus creating a taxable event. The 2003 tax cuts on capital gains and dividends have been producing far more revenue than the official estimates expected, including a surprise $100 billion windfall last year. As White House Budget Director Josh Bolten told Congress last week, that's real money even in his business.
Let's examine this one again. Record housing boom, sale of a house generates capital gains taxes, capital gains rates cut but a "surprise windfall" of capital gains tax revenue. Would you attribute this to a one time benefit of a historically anomalous housing boom, largely caused by lower interest rates for which the Federal Reserve is responisble or..."sale of stocks." ?California has has a massive "windfall gain" in tax revenues, to the best of my knowledge states like Michigan have not. Any guesses why ?
Another point, the tax motivated sales of stocks described above would be a one time event. Once one has taken unrealized capital gains on stocks held for a long period of time - the marginal increase in tax revenue has been realized. That's what a "windfall is. After that the same investors will buy new stocks and hold on to their long term gains. When they sell the tax revenues will be lower due to the reduced tax rates. The only way tax revenues would go up would be if the investor increased the frequency of his trading activity. And that doesn't add any new investment capital to the economy- it's just the same money floating around.
I manage investments, here's what I see in the real world as a consequence of the tax cuts among my clients:
1. No one moves money from bonds or cds into much riskier stocks just because the tax on dividends or capital gains has been reduced. On a risk return basis that would be crazy - on a risk adjusted basis, the cut in taxes doesn't offset the increase in risk. Bottom line no infux of new investment capital due to tax changes.
2. Yes, people are a bit more prone to take profits on long term capital gains due to the lower tax rates, creating a bit of a windfall for the treasury. Recently many people took that money out of stocks and into real estate speculation - I'm not sure that is a net benefit to the economy. Others may increase their stock trading, which does nothing to raise the level of investment in the economy.
3. I, along with many, many investment advisors and news/magazine articles have recommended people hold a higher proportion of dividend paying stocks in their portfolio to take advantage of the big decrease in tax rates to 15% (previously taxed at the ordinary income rate). The net effect of this is zero in terms of new investment in the economy it's money moving from one stock to another. No one is going to reallocate funds from 4% on a CD with principal protection to a stock yielding 4% with risk of capital loss. So going forward: lower revenues for the Treasury and no net increase in investment in the economy.
bottom line: once again WSj has the spin cycle on high speed
