From the Economist's View:
I don't mind the criticism, it's good for us and there are truths in what is said. But I always resent the arrogance of scientists from other fields thinking they can mosey on over to economics for a few minutes, diagnose our ills, and solve all our problems. I'd suggest they solve the problems in their own discipline first, or show a bit more humility when giving advice to others, especially when, as above, they are clearly unaware of vast swaths of literature such as the published work on corruption. And along those lines, and for the record, we're well aware of and have models for the list of things he mentions in his "abundantly clear" theory of market fluctuations. If he actually tried to build these models rather than simply casting aspersions at the existing paradigm, he'd find it isn't as clear as he thinks.
The same can be said about some noneconomist critics of neoclassical environmental economics, in my opinion.
