Lay summary
Recently, political theorists have increasingly reconsidered existing conceptualisations of economic phenomena. Sharp criticism has been levelled at concepts that "naturalise" economic phenomena by obliterating social and political nexuses. Against such "economicist" conceptualisations political theorists have subsequently dedicated considerable energy to theoretically (re-)politicise the economic. Conspicuously, though, most approaches politicise the economic only on a macro-level, which is to say, on the level of the organisation of the economic order and of institutionalised behaviour. The activities of market participants that constitute this economic order and the institutionalised behaviour, however, are usually not brought into focus. To politicise the economic, thus far, apparently means only to politicise the economy; It does not mean to politicise economic activity.
In order to complement the dominant macro-approach to the project of the theoretical politicisation of the economic, this dissertation project aims at contributing to carving out a political theory of micro-economic activity. To this task, a heuristic is erected which allows to discuss micro-economic activities such as acts of work, production, investment, or consumption with a view to politico-theoretical concepts. The dissertation project is guided by a postfoundational spirit. One of the central underlying questions is, therefore, whether such a political theory of micro-economic activity provides a conceptualisation of economic phenomena that is more useful for the emancipatory goal of fathoming possibilities for political action than existing approaches.
