How to do comparative dynamics on the back of an envelope for open‐loop Nash equilibria in differential game theory

Abstract: Summary The primal‐dual comparative statics method of Samuelson (1965) and Silberberg (1974) is extended to cover the class of non‐autonomous, finite horizon differential games in which a locally differentiable open‐loop Nash equilibrium exists. In doing so, not only is a one‐line proof of an envelope theorem provided but also the heretofore unknown intrinrsic comparative dynamics of open‐loop Nash equilibria are uncovered. The intrinsic comparative dynamics are shown to be contained in a symmetric and negativ… Show more

“…Hence, several “sharp” comparative statics may not hold if the capital accumulation game was generalized to a certain degree. Finally, , on the other hand, obtained intrinsic results for open‐loop Nash equilibria, as they employed only basic existence and smoothness assumptions in proving that in a general class of capital accumulation games “… the intrinsic comparative dynamics can be summarized in symmetric and negative semidefinite matrix that is subject to constraint.” The results to follow are equally as basic as those in , but rather than focusing on the intrinsic comparative dynamics, they give the steady state comparative statics and local comparative dynamics of open‐loop Nash equilibria of a capital accumulation game.…”
