Joan Robinson could write. Those first two paragraphs are awesome. Perhaps they jump out at me because I, too, have thought about "what do we really mean when we throw around the word 'Capital' in front of our students?" Has anyone ever done some schematic on how her textbooks vs. Samuelson's influenced the way textbooks were subsequently written by profession? I'm just curious if today's micro books have more DNA from one or the other. My suspicion is that Samuelson's DNA won out, but if I pull a copy of Robinson's "Economics of Imperfect Competition" (published 1930s through the 1940s) off the shelf there is lot there that looks like a modern IO textbook. Shorter: This is why I come to "Grasping Reality"!! Thank you!
