"Jackson, a Professor of Economics at Stanford University, “recognized the importance of networks for economics over 25 years ago,” says the award citation, in a theoretical paper that showed “how to predict which networks will form depending on the costs and benefits of forming links, and how these networks differ from the optimal ones.” His work, it continues, “has inspired an enormous literature, both theoretical and empirical, in which networks play an essential role in helping us understand financial markets, economic development, and a host of other economic phenomena.”
"In 1996, Matthew Jackson and Asher Wolinsky published “A Strategic Model of Social and Economic Networks,” in the Journal of Economic Theory, a paper regarded today as the launch pad for all subsequent literature on the social network approach or theory in economic analysis. In it, the authors define a network as a set of agents (people, but also firms, institutions and markets) connected by links, and modelled the characteristics such networks must exhibit in order to be efficient, to the extent that their component agents are satisfied and the network remains stable.
“Most of our interactions a human beings are social,” explained the new laureate in an interview shortly after hearing of the award. “We depend on other people for information, connections, opportunities, and also for norms of behavior. So the networks we are embedded in become very important determinants of our behavior and outcomes. In that first paper we tried to build the most basic model we could imagine about how people form relationships, whether they be business contacts, friendships, alliances or of any other sort.”
