  We derive generalized quasiclassical transport equations which include the
terms responsible for the Hall Effect in the vortex state of a clean type-II
superconductor, and calculate the conductivity tensor for an s-wave
superconductor in the high-field regime. We find that below the superconducting
transition the contribution to the transverse conductivity due to dynamical
fluctuations of the order parameter is compensated by the modification of the
quasiparticle contribution. In this regime the nonlinear behaviour of the Hall
angle is governed by the change in the effective quasiparticle scattering rate
due to the reduction in the density of states at the Fermi level. The
connection with experimental results is discussed.
