There are two differences: what is the appropriate notion of continuity (upper or lower hemicontinuity) and what is the appropriate topology (which games are “close”). In the previous problem, all perturbations of payoffs were allowed. This means that many games are close.

Websatisfy these two properties are not lower hemi-continuous. These results imply that the theorems of Chun (1990) can be extended to multi-valued solutions and that his efficiency axiom is redundant. More interest-ingly, his continuity axiom also appears to be redundant on the two important sub-classes of bargaining problems discussed previously.
