A variational inequality formulation of equilibrium models for end-of-life products with nonlinear constraints
First use of nonlinear constraints in economic network equilibrium problems. Proof of constraint qualification and convexity of the feasible set. Negative impacts of a strict collection target on product dematerialization. Product dematerialization preferred to additional virgin material purchases. High transaction costs prevent increase in recycled material usage.
