The rate equation for electron hopping between localized states is generalized to take account of the electron‐electron interaction in the Hubbard model. The generalized rate equation is used to discuss the effect of electron correlations, both repulsive and attractive, on the temperature dependence of hopping conductivity and thermopower.
