![]() A more egalitarian society with moderate inflation turns out to be more sustainable than an unequal society with low inflation. ![]() Analysis and numerical computations confirm the role played by intensity and frictions as key factors for sustainability by contrast with real gdp growth-as well as the interplay between resource scarcity, income inequality, and inflation. This viewpoint allows: ( i) the full-blown integration of a limited quantity of primary resources into a non-linear macrodynamics that is stock-flow consistent both in terms of matter-energy and economic transactions ( ii) the inclusion of natural and forced recycling ( iii) the inclusion of a friction term which reflects the impossibility to produce (and recycle)goods and services without exuding energy and matter wastes, and ( iv) the computation of the anthropically produced entropy as a function of metabolizing intensity and frictions. The distinctive approach emphasized here consists in capturing the economic impact of natural ecosystems’ depletion by human activities via a pinch of thermodynamic potentials. ![]() An economy is viewed as an out-of-equilibrium dissipative structure that can only be maintained with a flow of energy and matter. This paper presents a conceptual model describing the medium and long term co-evolution of natural and socio-economic subsystems of Earth.
