How to soften the US’ drop off the fiscal cliff

By Martin Feldstein

With the US elections less than six weeks away, it is time to think seriously about what will be done afterward to deal with the nation’s fiscal mess. Regardless of who wins, addressing the problem can no longer be postponed.

Americans are rightly focused on the “fiscal cliff” looming at the start of next year, when virtually all tax rates will rise, sucking more than 3 percent of GDP out of households and businesses. In addition, automatic cuts in spending on government programs will subtract nearly another 1 percent of GDP next year and similar amounts in future years. The US Congressional Budget Office warns that falling off the fiscal cliff would push the US’ economy into a serious recession next year.

The fiscal cliff is only part of the problem that must be solved. The bigger problem is that the US has an enormous fiscal deficit — now about 7 percent of GDP and predicted to grow rapidly in future decades as an aging population and rising healthcare costs increase government outlays for the “entitlement programs” that benefit middle-class seniors. Although politicians on both the left and the right recognize that these programs’ growth must be slowed to avoid massive deficits or very large tax increases, their growth is unlikely to slow enough to prevent the US’ debt/GDP ratio from rising.

Fiscal consolidation therefore requires additional revenue as well as slower growth in entitlement spending. The challenge facing US politicians will be to find a politically acceptable way to raise that revenue without undermining incentives and economic growth. The task is made more complex by the large number of legislators who insist that the deficit should be reduced by spending cuts alone.

Although no one can be sure how this complex problem will be solved, here is my best guess: Soon after the election, the US Congress will vote to postpone the fiscal cliff for about six months to allow time to work out an acceptable legislative solution. That solution will involve slowing the growth of Social Security pension benefits for future middle and upper-income retirees. US Republican candidate Mitt Romney has explicitly proposed this and US President Barack Obama indicated support for such an approach back in 2009.

The tougher problem will be how to raise revenue. The key will be to focus on the many special features of the tax code that are equivalent to government spending. If I buy a hybrid car, install a solar panel at my home, or upgrade to a more efficient water heater, I get a tax credit. If I buy a bigger home or just increase the size of my mortgage, I receive a larger deduction that reduces my taxable income, lowering my tax bill. While the US government is not giving me money, these special targeted tax breaks are no less “government spending” than they would be if the government sent me a check.

These features are rightly called “tax expenditures,” because they describe the government spending that occurs through the tax code. Eliminating or reducing these tax expenditures should therefore be seen as cutting government spending. Although the effect is to raise revenue, that is just an accounting convention. The fundamental economic effect is to reduce government spending.

So the key to raising revenue is to reduce tax expenditures, use some of the resulting revenue to reduce tax rates and devote the rest to reducing future deficits. Opponents of tax increases should see that, because such revenue-raising is really cutting government spending, it does not imply the adverse incentive effects of raising marginal tax rates.
