If producers have more information than consumers about goods' attributes, then they may use non-price (rather than price) adjustment mechanisms and, consequently, the market may reach a new equilibrium even if prices don't change. We study a situation where producers adjust the quantity per...

We study the diffusion of an idea, a product, a disease, a cultural fad, or a technology among agents in a social network that exhibits segregation or homophily (the tendency of agents to associate with others similar to themselves). Individuals are distinguished by their types - e.g., race,...

This paper studies a “market creating” firm that offers a matching environment, by charging an access fee, to a population of users who wish to form a match. We focus on an environment where users only observe a signal from their randomly assigned partner's type and the signal...
