We study cosmology in the five-dimensional Randall-Sundrum brane world with a stabilizing effective potential for the radion and matter localized on the branes. The analysis is performed by employing a perturbative expansion in the ratio {rho}/V between the matter energy density on the branes and the brane tensions around the static Randall-Sundrum solution (which has {rho}=0 and brane tensions {+-}V). This approach ensures that the matter evolves adiabatically and allows us to find approximate solutions to second order in {rho}/V. Some particular cases are then analyzed in detail.
