${\cal R}^2$ Supergravity
  We formulate $R^2$ pure supergravity as a scale invariant theory built only
in terms of superfields describing the geometry of curved superspace. The
standard supergravity duals are obtained in both "old" and "new" minimal
formulations of auxiliary fields. These theories have massless fields in de
Sitter space as they do in their non supersymmetric counterpart. Remarkably,
the dual theory of $R^2$ supergravity in the new minimal formulation is an
extension of the Freedman model, describing a massless gauge field and a
massless chiral multiplet in de Sitter space, with inverse radius proportional
to the Fayet-Iliopoulos term. This model can be interpreted as the "de-Higgsed"
phase of the dual companion theory of $R+R^2$ supergravity.
