A Non-Conservative Kinetic Framework for Econophysics

This paper presents a novel kinetic framework for macroeconomics grounded in the asymmetric microstructure of trade. Unlike classical models that assume value conservation, utility maximization, or equilibrium, this framework introduces three primitives—surplus generation, monetary exchange, and nonlinear decay—to model the economy as a non-equilibrium system with endogenous flows. Drawing on Boltzmann and Fokker–Planck dynamics, I derive agent-level transitions and aggregate macro variables such as wealth, money supply, surplus, decay, and inflation. I characterize laminar flow attractors, cyclic booms and busts, inflationary divergence, and inequality bifurcations as emergent patterns within the distribution of agents. This approach reframes macroeconomic behavior not as equilibrium outcome, but as flow geometry within a dissipative system.
