The idea of a social psychology of economic life is not obvious. From the point of view of mainstream economics, economic life – usually understood as the production, distribution, and consumption of goods and services – is under the scope of economics. As a mathematical science, economics is, to some extent, a rejection of social and psychological dimensions in the analysis of economic life. 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 (and its link to some of the most pressing societal issues nowadays) are derived from concepts and methods of psychology and other social sciences. PB431 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, and also to contributing to better solutions to societal problems.
