Public sector corruption is a common, but severely understudied, phenomenon in Public Administration (PA). Public sector corruption – e.g., in the form of bribery and rule-breaking – causes inequality in access to public services and results in inefficient allocation of resources, undermining the equity principle that lies at the heart of bureaucracies worldwide. Public sector corruption seriously undermines the general public’s trust in government and other public institutions. Prior research trying to examine the origins of public sector corruption traditionally use three different lenses, assuming that either
- the institutional context of country-specific cultures and traditions of administration is to be held accountable (Gelbrich et al., 2016; Hogdson & Jiang, 2007; Li et al., 2008; Navot et al., 2016; Sööt & Rootalu, 2012),
- organizational structures and dynamics are the key driving forces (Aguilera & Vadera, 2008; den Nieuwenboer & Kaptein, 2008; Frost & Tischer, 2014; Moore, 2008), or
- or identify individual character traits as determinants of deviant behavior (Bolino & Grant, 2016; Moore et al., 2012; Ripoll, 2019; Weißmüller et al., 2020).
To date, there is neither sufficient empirical evidence supporting either lens, nor a unified theory of public sector corruption. The central aim of this habilitation project is to close this research gap by advancing theoretical insights by collecting rich evidence about a selection of the main underlying mechanisms of public sector corruption and their interaction at the micro, meso, and macro level of behavior by conducting rigorous (quasi-)experimental research in fourteen countries.
In the spirit of Behavioral Public Administration, this habilitation research project responds to recent calls for more experimental work and empirical replication (van Witteloostuijn, 2016; Walker et al., 2019) by replicating my experimental studies within different sets of countries, organizations, and populations worldwide. That is, this research project involves a multi-lab design that combines rigorous multi-national and contextual replication and meta-analysis, employing both the method of agreement and difference. Furthermore, this habilitation project derives practical advice for public sector managers on ways to inform effective corruption prevention.
