MacKenzie, Laurent Thévenot and Jens Beckert in Europe. To this may be added Amitai Etzioni, who has developed the idea of socioeconomics, and Chuck Sabel, Wolfgang Streeck and Michael Mousseau who work in the tradition of political economy/sociology. The focus on mathematical analysis and utility maximisation during the 20th century has led some to see economics as a discipline moving away from its roots in the social sciences. Many critiques of economics or economic policy begin from the accusation that abstract modelling is missing some key social phenomenon that needs to be addressed. Economic sociology is an attempt by sociologists to redefine in sociological terms questions traditionally addressed by economists. It is thus also an answer to attempts by economists (such as Gary Becker) to bring economic approaches – in particular utility maximisation and game theory – to the analysis of social situations that are not obviously related to production or trade. Karl Polanyi, in his book The Great Transformation, was the first theorist to propose the idea of "embeddedness", meaning that the economy is "embedded" in social institutions which are vital so that the market does not destroy other aspects of human life. The concept of "embeddedness" serves sociologists who study technological developments. Mark Granovetter and Patrick McGuire mapped the social networks which determined the economics of the electrical industry in the United States. Ronen Shamir analyzed how electrification in Mandatory Palestine facilitated the creation of an ethnic-based dual-economy. Polanyi's form of market skepticism, however, has been criticized for intensifying rather than limiting the economization of society. New economic sociology A contemporary period of economic sociology, often known as new economic sociology, was consolidated by the 1985 work of Mark Granovetter titled "Economic Action and Social Structure: The Problem of Embeddedness". These works elaborated the concept of embeddedness, which states that economic relations between individuals or firms take place within existing social relations (and are thus structured by these relations as well as the greater social structures of which those relations are a part). Social network analysis has been the primary methodology for studying this phenomenon. Granovetter's theory of the strength of weak ties and Ronald Burt's concept of structural holes are two best known theoretical contributions of this field. Marxist sociology Modern Marxist thought has focused on the social implications of capitalism (or "commodity fetishism") and economic development within the system of economic relations that produce them.
