Social Networks - Virtual Issue

The economics of networks is a fast-growing area of study, covering some very important aspects of how people interact and how societies work. Networks impact on a wide variety of economic outcomes, including where people work, what they buy, how industries are organized, and how new ideas and information are shared and diffused. Economists working in this area are using and developing network-science tools to examine what sort of networks form, in what circumstances, and how these networks influence the behaviour of the people within them.

The economics of networks is a diverse field, and this Virtual Issue reflects that diversity. Some research contained in the collection examines individual behaviour in specific settings, such as income hiding in rural Africa, how consumption of goods is affected by consumption of others, and how co-worker networks affect labour mobility. Other papers explore network effects at the society or industry level, such as the geographical clustering of similar businesses, social networks and globalization, and the stability of the financial system.
