Abstract

This article develops an extension of Sraffian’s approach, considering a model
where the economy is divided into two sectors, the industrial and the agricultural. From a
system in physical units it is possible to determine labour values and prices of production.
The paper analyses the determination of labour values using Morishima’s suggestion, with
linear programming. It is shown that in an economic system with land scarcity the existence
of positive surplus-value is not a sufficient condition for positive profits.
