Harrison White also developed a perspective on market structure and competition in his 2002 book, Markets from Networks, based on the idea that markets are embedded in social networks. His approach is related to economic concepts such as uncertainty (as defined by Frank Knight), monopolistic competition (Edward Chamberlin), or signalling (Spence). This sociological perspective on markets has influenced both sociologists (see Joel M. Podolny) and economists (see Olivier Favereau).

Famous quotes containing the words markets and/or networks:
“A free-enterprise economy depends only on markets, and according to the most advanced mathematical macroeconomic theory, markets depend only on moods: specifically, the mood of the men in the pinstripes, also known as the Boys on the Street. When the Boys are in a good mood, the market thrives; when they get scared or sullen, it is time for each one of us to look into the retail apple business.”
—Barbara Ehrenreich (b. 1941)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
