We present the first complete set of evolutionary models developed to investigate the temporal evolution of the radio emission properties in compact starbursts. The constituents of the radio emission are the thermal free-free emission from the ionized gas, the non-thermal emission from young bright radio supernovae, and the non-thermal emission from old supernova remnants. Both instantaneous and continuous bursts are considered in a wide variety of models characterized by different metallicities and initial mass function (IMF) parameters, i.e. IMF slope and mass limits. The outputs of the models have a direct applicability in the study of dusty star-forming environments like those present in starburst galaxies, in general. Also, the models can be used for direct comparison with radio observations of ultraluminous infrared galaxies (ULIRG) to reveal the nature - active galactic nucleus (AGN) or nuclear starburst - of the energy source in the central regions of these galaxies.
