The equilibrium conditions for an economic system that produces output with several factors of production and which is subject to technological constraints are derived. Optimization of either output minus cost or integrated utility yields the conditions that output elasticities must be equal to...

The cost-share theorem and the related equilibrium structure of neoclassical economics are not consistent with thermodynamics and the process nature of energy conversion in wealth creation and technological evolution. In industrial economies energy's output elasticity is typically much larger...
