This paper considers platform competition in a two-sided market that includes buyers and sellers. One of the platforms benefits from a partial belief advantage, in that each side believes that it is more likely that the other side will join the advantaged platform.

Both oligopoly theory and experiments are concerned almost uniquely with sellers’ behavior. Buyers’ ability to exhibit non-trivial behavior in different market institutions remains unaddressed.

In a market with transferable utility, buyers might be willing to cooperate by exchanging side-...

Buyers in the first cohort arrive in period one privately informed about the distribution of their values, and then privately learn the value realizations in period two. Buyers in the second cohort a...
