ABSTRACT
We build our model of the productive system in the following way. We assume that there is one product (Y) whose daily output is either consumed (Yc ) or used to put back as an instrument of production or capital good into the productive system (Yk ). We assume that there are three factors of production: the capital good (K), labour (L), and land (N). We can express this basic production system in the following way: https://www.w3.org/1998/Math/MathML"> Y = Y c + Y k = F ( K L N t ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203106594/4c2e62d0-da44-488b-818d-99030835685f/content/math_3_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
