One problem that dogged Japan during its lost decade was a stop-and-go fiscal policy in which stimulus packages were administered in an “on again, off again” fashion and taxes were lowered and then raised. There is a risk that the U.S. could fall into this trap in an effort to strike a balance between short-term fiscal support and long-term budget integrity.
This strongly suggests that congressional leaders of both parties should embrace a pro-growth fiscal reform that would help to create long-run fiscal stability and foster certainty about future tax rates. With the 2001-2003 tax cuts set to expire at the end of 2010, the time is now to move ahead with broad-based reform.
A good starting point would be the bipartisan Wyden-Gregg tax reform bill. This bill is not incredibly bold, but is probably the best we could do in the current environment and is much better than the current tax code.
Wyden-Gregg would be revenue-neutral; it would simplify the tax code by reducing the number of personal income tax brackets to three from six and would do so without raising marginal income tax rates.
