We examine the efficiency and revenue properties of an asymmetric discriminatory auction with two bidders and two objects. While inefficient, a discriminatory auction may result in higher expected revenue than the efficient Vickrey auction

A comprehensive theory of large strategic games with (socioeconomic and biological) traits (LSGT) has recently been presented in Khan et al. (2012, 2013), and we present a reformulation pertaining to large distributional games with traits (LDGT).

We show that in the 2-sector RSS model, there is no optimal program for any initial stock when the felicity function is linear and the marginal rate [xi] equals unity. This settles a conjecture, unresolved since 2005.
