Companion papers develop a model of real-time hierarchical computation of resource allocations by boundedly rational members of an administrative staff. The nodes of a hierarchy are multi-person decision-making units offices. The current Paper uses a reduced form to address specific questions...

As the costs of generating and transmitting information fall, the main bottlenecks in communication networks are becoming the human receivers, who are overloaded with information. For networks of targeted communication, this paper discusses the meaning of information overload, provides a...

We use 6-digit bilateral trade data to document the effect of WTO/GATT membership on the extensive and intensive product margins of trade. We construct gravity equations for the two product margins where the specifications of these gravity equations are motivated by the model of Eaton and Kortum...

This Paper presents a model in which boundedly rational members of an administrative staff calculate resource allocations in real time. We consider a class of hierarchical procedures in which information about payoff functions flows up and is aggregated by a hierarchy, while allocations flow...

We examine how a firm's changing environment and the information constraints of its managers interact as determinants of the size of the firm's administration. Following the recent decentralised information processing literature, we assume that it takes individual managers time to process...

Dynamic models in which agents' behaviour depends on expectations of future prices or other endogenous variables can have steady states that are stationary equilibria for a wide variety of expectations rules, including rational expectations. When there are multiple steady states, stability is a...

For Bayesian games of strategic complementarities, we provide a constructive proof of the existence of a greatest and a least Bayes-Nash equilibrium - each one in strategies monotone in type - if the payoff to a player displays increasing differences in own action and the profile of types, and...
