Macroeconomic dynamics in a finite world based on thermodynamic potential.

This paper presents a conceptual model describing the medium and long term co-evolution of natural and socio-economic subsystems of Earth. An economy is viewed as an out-of-equilibrium dissipative structure that can only be maintained with a flow of energy and matter. The distinctive approach emphasized here consists in capturing the economic impact of natural ecosystems' depletion by human activities via a pinch of thermodynamic potentials.

Trickle-down climate risk regulation.

Climate change impacts-including flooding, wildfires, and crop failures-are destroying ecosystems, homes, infrastructure, farms, and businesses. Regulators around the globe are paying increasing attention to what these events mean for banks and the financial system, with several attending not only to bank impacts from, but also bank contributions to, climate change. The European Central Bank, for example, is signaling to banks that they must plan and make their transition away from financing of fossil fuels-to respond not only to their own risks but also to the science pointing to the necessity of this transition for the planet and financial system.

Prey-Predator Long-Term Modeling of Copper Reserves, Production, Recycling, Price, and Cost of Production.

The dynamics of copper production is modeled with a prey-predator approach linking the evolution of reserves to that of industrial wealth. Our model differs from earlier approaches in that it does not require a priori knowledge of the initial stock of resources. The model variables and a long-term reference price are estimated from historical data, taking into account the combined effects on price and reserve of technological improvements and changes in ore grade.
