Theoretical studies of effects caused by the interaction of indirect dipole excitons between each other and with a two-dimensional electron gas, which were supported by the Russian Foundation for Basic Research, have been reviewed. Particular attention is focused on situations where an exciton gas is in a state similar to a Bose- Einstein condensate. Excitons in electrostatic traps, polaron effects in hybrid electron-exciton systems, the response of a hybrid system to an external electromagnetic perturbation, and the drag of the exciton gas by a current in the two-dimensional electron gas have been considered. It has been shown that some electronic effects in hybrid systems can be used to identify a phase transition in the exciton system.
