  We discuss the mechanism for electroweak symmetry breaking in supersymmetric
versions of the standard model. After briefly reviewing the possible sources of
supersymmetry breaking, we show how the required pattern of symmetry breaking
can automatically result from the structure of quantum corrections in the
theory. We demonstrate that this radiative breaking mechanism works well for a
heavy top quark and can be combined in unified versions of the theory with
excellent predictions for the running couplings of the model. (To be published
