On the (In)Stability of Nonlinear Feedback Solutions in a Dynamic Duopoly with Renewable Resource Exploitation

Abstract: We revisit Fujiwara's (2008) di¤erential duopoly game to show that the degenerate nonlinear feedback identi…ed by the tangency point with the stationary state line is indeed unstable, given the dynamics of the natural resource exploited by …rms. To do so, we fully characterise the continuum of nonlinear feedback solution via Rowat's (2007) method, characterising the in…nitely many stable nonlinear feedback equilibria.JEL codes: C73, L13, Q2

“…The present game produces infinitely many nonlinear feedback solutions whose continuum can be fully characterised using the same procedure as in Lambertini (2016a) and Lambertini and Mantovani (2016), which in turn relies on Rowat's (2007). 6 Without replicating the entire analysis of the nonlinear case, here it suffices to characterise the degenerate nonlinear solution identified by the tangency between the highest isocline of the representative firm and the locus…”
