It isn't rocket surgery, as the Ivy League professor said

Selections: Tax Hikes and the 2011 Economic Collapse , By ARTHUR LAFFER in The Wall Street Journal

It shouldn't surprise anyone that the nine states without an income tax are growing far faster and attracting more people than are the nine states with the highest income tax rates. People and businesses change the location of income based on incentives. . .

it's also simple enough for most people to understand that if the government taxes people who work and pays people not to work, fewer people will work. Incentives matter.

People can also change the timing of when they earn and receive their income in response to government policies.

Just remember what happened to auto sales when the cash for clunkers program ended. Or how about new housing sales when the $8,000 tax credit ended? It isn't rocket surgery, as the Ivy League professor said.

Now, if people know tax rates will be higher next year than they are this year, what will those people do this year? They will shift production and income out of next year into this year to the extent possible. As a result, income this year has already been inflated above where it otherwise should be and next year, 2011, income will be lower than it otherwise should be.

Also, the prospect of rising prices, higher interest rates and more regulations next year will further entice demand and supply to be shifted from 2011 into 2010. In my view, this shift of income and demand is a major reason that the economy in 2010 has appeared as strong as it has. When we pass the tax boundary of Jan. 1, 2011, my best guess is that the train goes off the tracks and we get our worst nightmare of a severe "double dip" recession.

In 1981, Ronald Reagan—with bipartisan support—began the first phase in a series of tax cuts passed under the Economic Recovery Tax Act (ERTA), whereby the bulk of the tax cuts didn't take effect until Jan. 1, 1983. Reagan's delayed tax cuts were the mirror image of President Barack Obama's delayed tax rate increases. For 1981 and 1982 people deferred so much economic activity that real GDP was basically flat (i.e., no growth), and the unemployment rate rose to well over 10%.

But at the tax boundary of Jan. 1, 1983 the economy took off like a rocket, with average real growth reaching 7.5% in 1983 and 5.5% in 1984. It has always amazed me how tax cuts don't work until they take effect. Mr. Obama's experience with deferred tax rate increases will be the reverse. The economy will collapse in 2011.

Consider corporate profits as a share of GDP. Today, corporate profits as a share of GDP are way too high given the state of the U.S. economy. These high profits reflect the shift in income into 2010 from 2011. These profits will tumble in 2011, preceded most likely by the stock market.

If you thought deficits and unemployment have been bad lately, you ain't seen nothing yet.
