This post by Dave Altig is excellent. It links to two interviews with Neil Wallace, one in the Minneapolis Fed's Region magazine, and the other a forthcoming Macroeconomic Dynamics interview.
Neil has been a key influence on how I, and people who work in my field of study, think about the world. Today, I still own a well-worn copy of "Models of Monetary Economies," which is a watershed conference volume that changed how many economists thought about monetary economics. Neil is perhaps under-appreciated by the mainstream of the economics profession, but anyone who has been in a seminar room with him knows that few can match Neil in terms of deep and careful thinking about economics.
The two interviews are excellent reading, in many ways. If you look at nothing else, at least read the first section on microfoundations of macro in the Minneapolis Fed interview.
