This article presents empirical results of explorative case studies that examine whether the New Public Management mechanisms have improved the academic performance of PhD education in selected German and European economics departments. Our data rely on document analyses of organisational variables and in-depth semi-structured interviews with professors in Germany and several European countries. We propose a typology of departments along their PhD production technology and suggest that organisational improvements should look at the processes through which new professional standards gain acceptance in departments and at the means by which long-term incentive problems of collective action in a department are solved.
