Robustness and fragility in Leamer's sense are defined with respect
to a particular coefficient over a class of models. This paper
shows that inclusion of the data generation process in that class
of models is neither necessary nor sufficient for robustness. This
result holds even if the properly specified model has
well-determined, statistically significant coefficients. The
encompassing principle explains how this result can occur.
Encompassing also provides a link to a more common-sense notion of
robustness, which is still a desirable property empirically; and
encompassing clarifies recent discussion on model averaging and the
pooling of forecasts.
