Technique choice theory is traditionally modelled as a linear programming (LP) problem in math when the choice criterion is Okishio's profit rate criterion. However, some textual evidence suggests that Shaikh prefers DLF to mathematical programming; for example, on page 365 of Capitalism, he says:
Moreover, issues such as the choice of technique are then better treated via the stochastic methodology pioneered byDuménil and Lévy and Foley(DLF).
So, I am just wondering does this mean we should completely replace mathematical programming with the DLF framework when we study technique choice within the real competition theory?
