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 \ensuremathρ/V between the matter energy density on the branes and the brane tensions around the static Randall-Sundrum solution (which has \ensuremathρ=0 and brane tensions \ifmmode±\else\textpm\fiV). This approach ensures that the matter evolves adiabatically and allows us to find approximate solutions to second order in \ensuremathρ/V. Some particular cases are then analyzed in detail.
