It is shown that the thermodynamic law of conservation of mass, the so-called Materials-Balance-Principle, implies that the marginal product as well as the average product of a material resource input are bounded from above. This means that the Inada conditions, one of the standard assumptions...

Real production systems are often vertically integrated in thesense that one production process uses the unwanted joint product of another production process as input.This interrelationship links in a non-obvious way the different negative externalities stemming from theproduction processes. An...
