Implementation in iteratively undominated strategies relies on permissive conditions. However, for the sufficiency results available, authors have relied on assumptions that amount to quasilinear preferences on a numeraire. We uncover a new necessary condition that implies that such assumptions...

This paper examines the definition and continuity of expected payoffs in compact games with continuous payoff functions. There are three main results. First, we confirm that Glicksberg's (1952) original definition of expected payoffs as an iterated integral is mathematically sound under general...

We comment on the relation between models of information based on signals/partitions, and those based on sigma-algebras. We show that more informative signals need not generate finer sigma-algebras, hence that Blackwell's theorem fails if information is modeled as sigma-algebras. The reason is...

Though the various improvements and different measures of many aspects related to well being proposed by the Sarkozy Report will be very useful, an overall national success indicator to supplement/replace the traditional focus on GDP is needed. As an ultimate indicator, it has to be...
