The usual response to critics who state things like I just did is “give me a better model.” The idea is that we need to replace one reductionist model with another reductionist model. The reasoning seems to be that economics is like physics, where a lot of the history of the field is doing exactly that. (Physicists might be getting into “complexity,” which may or may not be a mathematical pseudo-science. In any event, this is not what people have in mind when they compare economics to physics.) If inflation is a complicated process, any reductionist model is going to fail.
Any empirical work on the link between inflation and the labour market is going to run into a snag that is the result of what I argue are relatively non-controversial positions.…
