This paper argues that Max Weber's work in economics is very interesting but has been unduly neglected. More precisely, Weber had a vision of economics as a very broad topic, to which not only economic theory but also economic history and economic sociology could contribute. Weber's term for this type of economics was Sozial-oekonomik or social economics. Weber himself made contributions to all three parts of social economics-espescially to economic sociology (he was one of the founders of Wirtschaftssoziologie) but also to economic history and (less so) to economic theory.
