It is shown that the Kaehler manifold of Wess-Zumino supergravity is the noncompact coset space SU(N,1)/(SU(N) x U(1)) and the Kaehler metric is an Einstein metric. The mass sum rule turns out to be the same as that in global supersymmetry. This mass sum rule makes it possible to have supersymmetry (SUSY)-breaking and vanishing scalar potential. Effective theories with or without the grand-unified-theory (GUT) sector are derived from the Wess-Zumino supergravity. They do not have scalar mass terms and trilinear terms among the soft SUSY-breaking terms. Their relevance to the gravitino mass problem is suggested. In a simple SU(5) SUSY GUT model they also show how the scalar partners of quarks and leptons and gauginos get their masses radiatively. The stability problem of the gauge hierarchy is also discussed. 21 references, 12 figures.
