My impressions of inframarginal economics are:
• It is best interpreted as providing underlying support for marginal economics.
• Inframarginalists take as self-evident that division of labour and specialisation economies are paramount in economic progress. To justify this, inframarginalists need to develop the empirical side of their field.
• Inframarginalists make insufficient use of computers. They specify stylised models, omitting many real-world phenomena that are routinely included in models computed for applied work. Inframarginalists seem wedded to analytical solutions.
• Inframarginalists write papers mainly for inframarginalists. They need to demonstrate the value of their work by making it relevant to others.
