Research crossing boundaries between sociology and economics result in new subdisciplines. The most significant ones are economic sociology, institutional economics and rational choice theory. Scholars from these areas strive to justify distinctiveness of their approaches, they stress theoretical advantages of economics as a science, while sociology is regarded mainly as a field of empirical research. Contesting such an approach, the authoress focuses on theories of Talcott Parsons, Niklas Luhmann and Pierre Bourdieu as examples of a 'sociological approach' to economic phenomena. .
