1.0 Introduction

My consistent position is that Sraffa and his followers, besides

recovering an alternate approach to value and distribution found

in classical economics and Marx, demonstrated the logical invalidity

of marginalist economics.

Empirical results are irrelevant to questions of logical validity.

consistent with an emphasis on widespread marginal adjustments.
