Quite interesting and seems there's a bit of a brouhaha with him, Paul Krugman, Brad DeLong, Greg Mankiw, Matt Yglesias, and Tyler Cowen.

An interview with Robert Barro
...Conor Clarke: What I am trying to do is sort of apply a barometer to modern macroeconomics and see where the profession is, because I am sort of confused by a lot of things.
Robert Barro: [laughs] Probably the fault of the profession.
Well, one thing I am confused by is where all of this resurgent interest and fiscal policy came from. That's very broad. But where do you think it came from? When I took macroeconomics in college there was not a lot about fiscal policy.
It came from the crisis and memories of the Great Depression and the fact that monetary policy seems to have done not a tremendous amount, and conventional stuff doesn't look like its going to work anymore. And it's about grasping at straws to try and find something else.
And I take it from the Wall Street Journal piece you wrote last week... well, the piece is just specifically about measuring multipliers, but I take it that you are fairly skeptical in general that fiscal policy will boost aggregate demand.
Right. There's a big difference between tax rate changes and things that look just like throwing money at people. Tax rate changes have actual incentive effects. And we have some experience with those actually working....
...I'm not in a position to know things like the degree to which Paul Krugman counts as a relevant expert on new Keynesian economics.
He hasn't done any work on that. Greg Mankiw has worked in that area.
And Greg Mankiw is, I guess, skeptical of spending for the same reasons that you are: he says that there's some empirical evidence -- I think he cites the Christina Romer study from 15 years ago -- that a dollar of tax cutting has a larger impact than...
The Romer evidence is very recent actually. It's an ongoing project....
...The last thing is just about the stimulus bills as it stands. Two things here. One thing is what do you think about the ratio of spending to tax relief in the bill. And the second is, if you judge it by Larry Summers standard -- that stimulus be temporary, timely and targeted -- does it clear the bar?
This is probably the worst bill that has been put forward since the 1930s. I don't know what to say. I mean it's wasting a tremendous amount of money. It has some simplistic theory that I don't think will work, so I don't think the expenditure stuff is going to have the intended effect. I don't think it will expand the economy. And the tax cutting isn't really geared toward incentives. It's not really geared to lowering tax rates; it's more along the lines of throwing money at people. On both sides I think it's garbage. So in terms of balance between the two it doesn't really matter that much....
