Abstract

A comprehensive theory of large strategic games with (socioeconomic and biological) traits (LSGT) has recently been presented in Khan et al. (2012 a and b), and in this paper, we present a reformulation pertaining to large distributional games with traits (LDGT). In addition to a generalization of work initiated and advocated by Mas-Colell (1984), we delineate the role of saturated spaces, as studied in Keisler-Sun (2009) in the reformulated theory, and consider questions pertaining to \lq\lq realizations" of equilibrium distributions that were not previously asked.
