There is a very interesting and fairly recent literature on production from a "structuralist" approach associated with names such as Michael Landesmann, Roberto Scazzieri, Mauro Baranzini, Harald Hagemann and others, some of whom I believe were students/junior colleagues of Pasinetti and/or Lowe (see, e.g., the cites below). Since someone mentioned Georgescu-Rogen, I can't resist reference to his remark, I don't have the citation, that in a one-commodity model, abstaining from consuming yogurt results immediately in more bulldozers!
