We assume that the radio emission involved in superluminal motions in quasars originated close to a compact object. We analyze the effect of the bending of light and gravitational time delay, due to the quasar's proper mass, on the apparent superluminal motions. For the sake of simplicity we consider the source to be moving in a moderate gravitational field region, in order to apply the linear approximation. We found that the relativistic beaming interpretation of the superluminal motions may be improved only if we accept huge masses for the quasar of the order of 1012 - 1013 solar mass.
