This paper explores the value of memory in decision making in dynamic environments. We examine the decision problem faced by an agent with bounded memory who receives a sequence of signals from a partially observable Markov decision process. We characterize environments in which the optimal...

<Para ID="Par1">We develop revealed preference tests for models of multi-product oligopoly, building on the work in Carvajal et al. (Econometrica 81(6):2351–2379, <CitationRef CitationID="CR8">2013</CitationRef>). We analyze a Cournot model with multiple goods and show that it has testable restrictions when at least one good is produced by two or more...</citationref></para>
