AbstractTraditionally, universities stand for independent, high-quality, and curiosity-driven research and education. Yet, since neoliberal reforms in the 1980s, they have been increasingly exposed to external pressures towards more efficiency and economic value orientation. To manage the tasks corresponding to these market-based values, a new and fast-growing group of professional staff has emerged. Some authors argue that they challenge academic norms, or academic professional logics, while importing market norms, or market logics, through previous employment in and current relationships with the private sector. We empirically test this assumption based on original survey data of three groups of professional staff of universities and associated medical centers in the Netherlands: business developers, grant advisers, and research policy officers. We asked them about their ideas about universities to capture their institutional logics. Respondents also indicated previous employment and the strength of their professional relationships. Using multiple linear regression models, we find that professional staff with private sector experience indeed have stronger market logics. We find the same for those with stronger relationships with private sector companies. Yet, on average, the academic professional logic of professional staff is considerably higher than their market logic. Additionally, the effect of private sector experience and stronger relationships with private sector companies on the market logic is moderate. Thus, our data suggests that professional staff do not challenge academic norms. Therefore, there seems to be little need for meeting them with skepticism regarding their role in unwanted organizational change.
