We examine a simple economic model of network formation where agents benefit from indirect relationships. We show that small-world features-short path lengths between nodes together with highly clustered link structures-necessarily emerge for a wide set of parameters. (JEL: D85, A14, C72)...

We present a model where agents care about their neighbors' actions and can pressure them to take certain actions. Exerting pressure is costly for the exerting agent and it can impact the pressured agents by either lowering the cost of taking the action (which we call "positive pressure" ) or...

This paper presents conditions for a resolution of the Grossman–Stiglitz paradox of informationally efficient markets. We display a market with asymmetric information where a privately revealing equilibrium obtains in a competitive framework and where incentives to acquire information are...

A model is presented of a uniform price auction where bidders compete in demand schedules; the model allows for common and private values in the absence of exogenous noise. It is shown how private information yields more market power than the levels seen with full information. Results obtained...
