We show that the initial dynamics of resonantly-excited excitons in quantum wells is controlled by several processes such as radiative recombination, spin relaxation of excitons, electrons and holes, and scattering between different in-plane momentum states of excitons. We present a unified analysis of the results, which provides quantitative information about these important rates, and a good physical understanding of the initial dynamics of non-equilibrium excitons. In particular, we show that the enhanced radiative recombination rate of excitons makes an important contribution to the early decay of the photoluminescence.
