As a result, NASA's top managers set up an ambitious launch schedule, which was proving difficult to meet. The political pressure that NASA's top management was experiencing was transmitted down to lower levels of the bureaucratic hierarchy. The middle managers thus felt the burden not only of the expectations of their bureaucratic superiors, but also of the expectations of the agency's political principals. It was in this context that NASA's middle management decided that it was safe to proceed with the planned launch of the shuttle, and not to delay the process by resolving the technical issues the engineers raised. The middle management thus prioritized addressing the expectations stemming from the agency's political and bureaucratic accountability, at the expense of its professional accountability, ultimately leading to the disaster. This influential analysis of the Challenger accident encouraged numerous investigations of the accountability forces operating in the public sector in the decades to come. The simultaneous operation of multiple accountabilities, in particular, has garnered a lot of interest among public administration scholars (for example Koppell, 2005;Romzek & Ingraham, 2000;Schillemans & Bovens, 2011). But while the various accountability mechanisms have been carefully traced and categorized, their consequences on the decision-making behavior of individual public sector actors have been subjected to far less scholarly scrutiny (Schillemans, 2016;Yang, 2012). We thus have far less insight into why NASA's middle management decided to give priority to the demands of their political principals and hierarchical superiors, as opposed to the ones of the technical experts. The decision-making behavior of public sector actors under the pressure of accountability is therefore a central subject of investigation in this dissertation.
IntroductionWhile public sector accountability mechanisms primarily operate at the organizational level, their effects reverberate through the various segments and individuals within organizations, as the case of the Challenger tragedy illustrates. Through board meetings, discussions in the media, or contacts with clients, the pressures of accountability expectations are felt by individual public sector managers and employees alike.Felt accountability, as psychologists have dubbed this (Hall et al., 2017), affects one's reasoning about the problem at hand, the calculations of priorities, the willingness to invest additional effort, or to take risks, and subsequently the decisions one makes and the behaviors one performs in the workplace (Lerner & Tetlock, 1999). These individual-level decisions and behaviors in turn shape the organizational outcomes. The meso and macro-level accountability pressures, external to the organization, are thus channeled through the micro-level within the organization, before they return meso or macro-level outcomes (Overman et al., 2020). To understand meso and macro-level outcomes in the public sector, it is therefore crucial to learn how the ind...
