This paper proposes a theoretical framework for studying the invention of new products when demand is uncertain.

Besides offering a close fit of these diverse networks, the model allows us to impute the relative importance of search versus … random attachment in link formation.

We study an equilibrium sequential search model where buyers have potentially downward-sloping demand and with … bilateral heterogeneity in buyers' search costs and firms' production costs. We show that downward- sloping demand and … distribution of search costs is 'uniform-like'. It follows that the set of equilibrium price distributions is nonempty and has a …

Under the second … version, the seller guarantees the same price if the buyer chooses to return immediately after a search (presumably because a …
