This is a reply to the criticisms raised by William Jefferies (Jefferies, 2020) to my article “Sraffa and the Labour Theory of Value: a note” (Araujo, 2019). In Jefferies (2020) the author has given great emphasis to the question of physical commensurability between input and output in Sraffa’s price model.
