Weak and Strong Time Consistency in Differential Oligopoly Games with Capital Accumulation

Abstract

We illustrate two differential oligopoly games with capital accumulation where, alternatively, the accumulation dynamics of productive capacity is modelled either `a la Solow Swan or `a la Ramsey. We show that in the first case the open-loop Nash equilibrium is only weakly time consistent, while in the second it is strongly so, although the Ramsey game is not state linear.
