Julio, I would say the problem is not the old Cambridge capital issues, although I take those seriously, nor even Keynesian issues, nor Hildenbrand-Grandmont aggregation issues, nor even Sonnenschein-Mantel-Debreu problems, although all of these are relevant. I would say modern complexity theory is the current wave of analysis here. Much modern macro is GE, but a lot of it is also representative agent, even as many increasingly realize how ridiculous that is. Barkley Rosser
