Networks have a widespread economic significance. They structure the way that market traders interact and configure relations within and between social groups, urban centres and nation states. Networks also determine patterns of authority and dominance in hierarchical organisations such as governments. This authoritative selection of recent work on the economics of networks will appeal to researchers in microeconomics, spatial and business economics as well as international economics and development. Social scientists and natural scientists will also find the book useful as a guide to the increasing wealth of economic literature on networks.
