The Limits of Economics

Here’s a fascinating article from Christopher Hayes on the limits of economics:

The simple models have an explanatory power that is thrilling. Once you’ve grasped the aggregate supply/aggregate demand model, you understand why stimulating demand may lead, in the short run, to growth, but will also produce inflation. But the content of that understanding turns out to be a bit thin. Inflation happens because, well, that’s where the lines intersect. “A little economics can be a dangerous thing,” a friend working on her Ph.D in public policy at the U. of C. told me. “An intro econ course is necessarily going to be superficial. You deal with highly stylized models that are robbed of context, that take place in a world unmediated by norms and institutions. Much of the most interesting work in economics right now calls into question the Econ 101 assumptions of rationality, individualism, maximizing behavior, etc. But, of course, if you don’t go any further than Econ 101, you won’t know that the textbook models are not the way the world really works, and that there are tons of empirical studies out there that demonstrate this.”
