“Lending and the smoothing of uninsurable income” was published in

*Contractual Arrangements for Intertemporal Trade*edited by E. C. Prescott and N. Wallace (University of Minnesota Press, 1987). The book is out of print, and is posted with the publisher's permission.“Individual-level randomness in a nonatomic population” is unpublished research that provides a set-theoretic construction of a continuum of i.i.d. random variables, such that the integral of each sample path with respect to a measurable subset of the indexes is the product of the measure of the index subset and the expectation of the random variable. The construction is an alternative to a construction by nonstandard analysis. (Cf. Robert M. Anderson, ”Non-standard analysis with applications to economics,” in W. Hildenbrand and H. Sonnenschein, editors, Handbook of Mathematical Economics, volume 4, chapter 39, pages 2145–2208. Elsevier, 1991.) This paper was rejected for publication, but all of the referees (4 reports were received in total) judged that the results are mathematically sound.

“Iterated elimination of dominated strategies in countable-strategy games” [working title] Draft, 2011.04.28.

“Events concerning knowledge” 2012.04.17. Common knowledge of a Borel event is shown to be a co-analytic event, and is therefore universally measurable. An extension of Aumann's “agreement theorem” regarding common knowledge of posterior probabilities is proved in the framework of a measure space defined on a complete, separable, sigma-compact metric space.

“Embedding an analytic equivalence relation in the transitive closure of a Borel relation [

*Journal of Logic and Analysis*5:4 (2013)]. The transitive closure of a reflexive, symmetric, Borel relation is an analytic equivalence relation. Does some smaller class contain the transitive closure of every reflexive, symmetric, closed relation? An essentially negative answer is provided here. The Baire space is homeomorphic to an open subset of itself, X, that has an open complement. It is shown that any analytic equivalence relation E on the Baire space can be embedded homeomorphically in the transitive closure of a reflexive, symmetric, closed relation on X. Specifically, the relation can be constructed as the union of two closed equivalence relations. This result shows that Aumann's common-knowledge operator can map individuals' information partitions of low complexity to a considerably more complex common-knowledge partition.“Long-run implications of maximizing posterior expected utility” (with Fatemeh Borhani) This paper concerns whether or not Bayesian decision theory has any revealed-preference implications regarding the asymptotic behavior of a rational agent.
