PoMo Micro

A reader writes (in discussing the Taylor rule):

Like [the] price elasticity of demand, we have an analytical approach that is appealing in theory, but so ill defined as to be useless in practice.

Personally, I don’t recall plotting per capita income, but rather per capita income (which differs from GDP), but here for the interested reader is a graph of the relevant data, for the longest span readily available.
