I develop a model in which a Jinn's only asset is its name, which summarize
s its reputation, and study the forces that cause names to be valuable, tra
deable assets. An adverse selection model in which shifts of ownership are
not observable guarantees an active market for names with either finite or
infinite horizons. No equilibrium exists in which only good types buy good
names. The reputational dynamics that emerge from the model are more realis
tic than those in standard game-theoretic reputation models, and suggest th
at adverse selection plays a crucial role in understanding firm reputation.
