Readings Keyed to the Macroeconomic Speeds

Thinking about distinct macroeconomic speeds is an approximation method that is alluded to even in undergraduate macro when we talk about the “short run” and the “long run.” (Note that what is there called the “long run” is here called the “medium run” because “long run” is reserved for the long-run growth steady state in which capital has adjusted.)

Chris House and I are working on a paper with a formal development of this as an approximation method. Also in that spirit of dynamic Taylor approximations, you might be interested in this paper:

One general economic issue I emphasize is imperfect information processing. This paper and this tweetstorm turned into a blog post are relevant to that:

I also emphasize that partial equilibrium analysis is an important part of macro as well as general equilibrium analysis:
