seminar: Coupled Climate–Economics Modeling and Data Analysis

speaker: Michael Ghil (Département Géosciences, Ecole Normale Supérieure, Parigi)

abstract: This talk will address the mathematics of non-equilibrium macroeconomics 5 and of its interaction with climate variability and climate change 1,2. First, I will review earlier work on endogenous business cycles (EnBCs) 5 and on how they affect the impact of natural catastrophes on the economy. Based on these previous findings, I will formulate an economic version of fluctuation–dissipation theory and show that it is supported by available data from the U.S. Bureau of Economic Analysis 4. Finally, results on the synchronization of business cycles across the world will be presented 3.
