An evolutionary model is presented for a multi-sector, multi-instrument financial equilibrium problem, with general utility function and including policy interventions in the form of taxes and price controls. We give the evolutionary financial equilibrium condition, prove an equivalent variational inequality formulation, from which an existence result follows.
Keywords: variational inequality formulation, equilibrium condition, time-dependent requirements., financial problem.
