  The supersymmetric analog of the Goldberger-Treiman relation plays a critical
role in the low energy effective theory of models in which supersymmetry is
spontaneously broken in a hidden sector. The interactions that connect the
hidden and visible sectors break a global symmetry, which implies that the low
energy theory must be constructed consistently in inverse powers of the
messenger scale. The Goldberger-Treiman relation determines the couplings of
the Goldstino to the visible sector fields. These couplings are fixed by the
soft supersymmetry breaking terms within a power counting scheme that is stable
under radiative corrections. We describe the power counting of the low energy
effective theory, first for a toy model of extended technicolor and then for
the supersymmetric standard model. One implication of this work for
supersymmetry phenomenology is the observation that Goldstino loops can
destabilize the weak scale if the low energy theory is not constructed
consistently. Another is that Goldstino loops induce all visible sector
operators not forbidden by symmetries. The magnitudes of these operators are
determined by the consistent power counting of the low energy effective theory.
