With the restriction that the effective action should contain at most two derivatives and not more than four-fermion couplings, the features of the low-energy effective action obtained by Seiberg based on $U(1)_R$ anomaly and non-perturbative $β$-function arguments are shown to emerge.20 pages, epsf file, to be contributed to LP99, SLACHigh Energy Physics - Theorytext
