There's No Stimulus Free Lunch
The increased federal debt caused by this stimulus package has to be paid for eventually by higher taxes on households and businesses. Higher income and business taxes generally discourage effort and investments, and result in a larger social burden than the actual level of the tax revenue needed to finance the greater debt. The burden from higher taxes down the road has to be deducted both from any short-term stimulus provided by the spending program, and from its long-run effects on the economy.
Our own view is that the short-term stimulus from the legislation before Congress will be smaller per dollar spent than is expected by many others because the package tries to combine short-term stimulus with long-term benefits to the economy. Unfortunately, short-term and long-term gains are in considerable conflict with each other. Moreover, it is very hard to spend wisely large sums in short periods of time. Nor can one ever forget that spending is not free, and ultimately it has to be financed by higher taxes.
