Transport properties of Ba1-xKxBiO3 and Nd2-xCexCuO4 are calculated by solving the Boltzmann equation using the electronic energy-band structures obtained with the local-density full-potential linearized augmented-plane-wave method. For Ba1-xKxBiO3 the calculated Hall coefficient RH is (two times) larger than experiment and has the correct (negative) sign. For Nd2-xCexCuO4 a positive Hall coefficient is obtained for the magnetic field oriented perpendicular to the Cu-O planes. This is to be compared with a negative experimental value found for x<0.18 and recent experiments that show a change of sign of this Hall coefficient (from negative to positive with increasing x) for x=0.18. These results indicate a trend (previously found for La2-xSrxCuO4) towards a regime in which the conventional band-theoretical description comes into better agreement with experiment. The highly anisotropic nature of the resistivity of Nd2-xCexCuO4 is discussed.
