Before revision:  We contrast our proposed weak perturbations against what we call strong perturbations, whereby the wealth equation is directly influenced by the changing parameters , and find that both points of view generally yield different sensitivities unless e.g. if initial parameters and their perturbations are deterministic.
After revision:  We contrast our proposed weak perturbations against what we call strong perturbations, whereby the wealth equation is directly influenced by the changing parameters . Contrary to conventional wisdom, we find that both points of view generally yield different sensitivities unless e.g. if initial parameters and their perturbations are deterministic.
