Query: Separability vs. robustness of Orlicz spaces: financial and economic
  perspectives   We investigate robust Orlicz spaces as a generalisation of robust
$L^p$-spaces. Two constructions of such spaces are distinguished, a top-down
approach and a bottom-up approach. We show that separability of robust Orlicz
spaces or their subspaces has very strong implications in terms of the
dominatedness of the set of priors and the lack of order completeness. Our
results have subtle implications for the field of robust finance. For instance,
norm closures of bounded continuous functions with respect to the worst-case
$L^p$-norm, as considered in the $G$-framework, lead to spaces which are
lattice isomorphic to a sublattice of a classical $L^1$-space lacking, however,
any form of order completeness. We further show that the topological spanning
power of options is always limited under nondominated uncertainty.
