  In this paper, we investigate the cosmological consequences of ghost dark
energy model in modified Gauss-Bonnet gravity. We construct ghost dark energy
$f(G)$ model by using correspondence scenario for both interacting and
non-interacting schemes. For this purpose, we consider the FRW universe with
pressureless matter and power-law scale factor. We examine the behavior of the
equation of state parameter and check the stability of ghost dark energy model
through the squared speed of sound parameter. We also analyze the behavior of
phase planes like $\omega_{eff}-\omega'_{eff}$ and $r-s$ graphically. It is
found that the equation of state parameter represents the quintessence era for
non-interacting while the phantom phase of the universe for an interacting
case. The squared speed of sound indicates stable ghost dark energy model for
both cases. The $\omega_{eff}-\omega'_{eff}$ plane shows thawing region for
non-interacting while freezing region for an interacting case. The $r-s$ plane
corresponds to the Chaplygin gas model in both scenarios. We conclude that
ghost dark energy model describes the evolution of the universe for the
appropriate choice of parameters.
