The no-trade interval of Dow and Werlang : some clarifications



The aim of this paper is two-fold : first, to emphasize that the seminal result of Dow and Werlang [9] remains valid under weaker conditions and this even if non-positive prices are considered, or equally that the no-trade interval result is robust when considering assets which can yield non-positive outcomes, second to make precise the weak uncertainty aversion behavior characteristic of the existence of such an interval.
