The normal state resistivity of highTc Y-Ba-Cu-O compounds has been investigated and it is shown that the room temperature resistivity depends exponentially on the volume fraction of the non-superconducting phase. It is further shown that the dependence of normal state resistivity on temperature upto 300 K can be explained on the basis of a short-range co-operative electron-phonon coupling. This model also explains the observed positive Seebeck coefficient for the pure phase superconducting sample.
