This document summarizes a research paper on one-sided uncertainty and delay in reputational bargaining. It outlines the motivation, literature, models and equilibria discussed in the paper. The motivation is a two-person infinite bargaining model where one player may have one of two discount factors. The literature discussed includes previous work on adding behavioral types or incomplete information that results in unique equilibria with delay. The analysis of the models and equilibria is described as quite messy and the intuition for behavioral types is not entirely clear.
