We study the possibility of trade for purely informational reasons. We depart from previous analyses (e.g. Grossman and Stiglitz (1980) [22] and Milgrom and Stokey (1982) [32]) by allowing the final payoff of the asset being traded to depend on an action taken by its eventual owner. We characterize conditions under which equilibria with trade exist.
