Mokyr on technological change, and Brad Delong responds (via Economist's View).
Another take on behavioural economics: "Please, not another bias!"
There aren’t 165 human biases. There are 165 deviations from the wrong model.This reminds me of something Werner Güth said to me once: "I saw so many papers coming out with stories of inequality, betrayal aversion etc. that I decided to cultivate aversion aversion."
He then added a typically profound and provocative aside, that much later, he had realised that risk aversion was equally problematic. His point, I think, was that the concept of risk aversion, which is absolutely mainstream microeconomics, is itself a sticking plaster over our failure to come up with good descriptions of human decision-making.
