In this paper the behavior of parametric solutions of oligopolistic network equilibrium problems is studied. Differential sensitivity results are obtained which quantify the approximate changes in oligopolistic network equilibrium solutions that correspond to changes in the problem data. Specifically, it is shown that under mild assumptions the equilibrium solutions are continuously differentiable and formulas for their Fréchet derivatives are derived.
