We consider a pairwise kidney exchange model. Roth et al. (2005) define priority matchings of the model and introduce a mechanism to derive them. In this paper, we re-examine the priority matching. First, we consider a general priority ordering where multiple patients may hold equal priority. We...

In this note, we analyze a sequentially rationalizable choice model with a transitive rationale and a standard preference. The model in this note is more restrictive than the Rational Shortlist Method (RSM) model which is proposed in Manzini and Mariotti (2007) to capture cyclic behavior. Yet, a...

In a common-values election where voters receive a signal about which candidate is superior, suppose there is a small amount of uncertainty about the likelihood of the signal's outcome, holding fixed the correct candidate. Once this uncertainty is resolved, the signal is i.i.d. across agents....
