strictly above their nominal level. Following the work of Kaido, Molinari, and Stoye (2016),
we 'calibrate'the radius of the Wald ellipsoid to guarantee that—for a given posterior on the
reduced-form parameters—the robust Bayesian credibility of the projection method is exactly
1− α. If the bounds of the identified set are differentiable, our calibrated projection also
covers the identified set with probability 1− α. We illustrate the main results of the paper …
