The idea of a social psychology of economic life is not obvious. From the point of view of mainstream economics, economic life is under the scope of economics. Economics as a mathematical science is, to some extent, a rejection of social and psychological dimensions in the analysis of economic life. And as the “queen of social sciences”, mainstream economics was even considered by some authors as the framework (the so-called “economic imperialism”) for studying social and psychological processes out of the economic life. Yet, some of the most important advances over the last four decades in the understanding of human economic behaviour are derived from concepts and methods of psychology and other social sciences. PS415 presents how social psychology (broadly interpreted to include micro-sociology, cultural anthropology and social neuroscience) is the key to understanding real-world economic life by taking into account cognitive, affective and social processes.
