Notes
1 I pointed out that Sraffa did not object to the use of Marshall’s method in appropriate settings, but he did object to Marshall’s use of it in conjunction with supply and demand functions and curves.
2 On this, see Nevile, Harcourt and Kriesler (2015, especially pages 109-10), and Solow’s (1997 and 2000) wise comments on the issues.
3 For the distinction between the concepts of period and run, so often now regarded as interchangeable, see Harcourt (2012).
