from The Great Debate:

Take advantage of today’s low costs

Reuters invited leading economists to reply to Lawrence Summers’ op-ed on his reaction to the debt ceiling deal. We will be publishing the responses here. Below is Franks’s reply. Here are responses from Laura Tyson, Benn Steil, Russ Roberts, Donald Boudreaux and James Pethokoukis as well.

I'm in general agreement with Larry Summers' piece. If it had been my column to write, I'd have been more emphatic about how much more important the unemployment problem is than the deficit problem. Deficits need to be reduced, yes, but not in the midst of a deep downturn. If we could put just half of the people who are either unemployed or underemployed back to work, for example, national income would be larger by more than ten times the interest we're paying on the 2011 deficit. The extra income tax revenue alone would be enough to cover the interest on last year's debt.

I'd also have hit harder on the claim by ostensible deficit hawks that extra spending right now would impoverish our grandchildren. Some of the most vivid and easily understood counterexamples involve infrastructure maintenance. According to the Nevada Department of Transportation, repairing a damaged 10-mile stretch of Interstate 80 would cost $6 million if we did the work today. But if we postpone repairs, weather and traffic will continue to damage the roadbed. If we wait just two years, the cost of bringing that same stretch of road up to par rises to $30 million. There are thousands of similar projects crying out to be done.

The Nevada cost inflation estimates, by the way, take no account of the special circumstances associated with the current downturn. There are idle machines and workers who could do the work today, for example, but if we wait a few years, we'll have to bid them away from other useful tasks. Materials are cheap in world markets now, but if we wait, their prices will rise as the global economy recovers. Interest rates on 10-year T-bills are near record lows. They'll be higher if we wait. No one proposes to allow the interstate highways to deteriorate back to gravel. We either fix them now or we fix them later. Fixing them now is MUCH cheaper, AND it will put unemployed workers back on the job. If we REALLY wanted to impoverish our grandchildren, it would be hard to come up with a better strategy than failing to undertake these projects right away.

How to silence Larry Summers

White House economic adviser Lawrence Summers is rarely at a loss for words, which makes Tuesday’s question-and-answer session at the National Press Club in Washington downright astonishing.

Summers, whose term as president of Harvard University ended rather abruptly after he made some unfortunate remarks about women and math and science aptitude, knew he was on very thin ice when he was asked a question about gender differences in retirement savings.

As soon as the question was asked, laughter spread around the room. Summers himself paused for a good 20 seconds before cracking a joke about how the question must have frightened his staff.
