内容摘要:This paper extends Oniki’s (1973) approach to comparative dynamics in the optimal control theory to the differential game setting. The comparative dynamics of the symmetric open-loop Nash equilibrium are derived for a generalized capital accumulation differential game. The effects of changes in parameters on the entire equilibrium paths of the capital stock, the investment rate and firms’ own costate variables are studied in the perturbed phase plane. An interesting implication of the derived comparative dynamics is that they could help produce sharper envelope results. Specifically, it is shown that firm’s own costate variable uniformly underestimate the shadow value of the initial capital stock.
