Buzz: Face-to-face contact and the urban economy
Abstract
This paper argues that existing models of urban concentrations are incomplete unless grounded in the most
fundamental aspect of proximity; face-to-face contact. Face-to-face contact has four main features; it is an
efficient communication technology; it can help solve incentive problems; it can facilitate socialization and
learning; and it provides psychological motivation. We discuss each of these features in turn, and develop
formal economic models of two of them. Face-to-face is particularly important in environments where
information is imperfect, rapidly changing, and not easily codified, key features of many creative activities.
