  • Unintended Consequences of UN Sanctions On the Shortlist for the 2023 Bernard Brodie Prize

    Since 2009, Contemporary Security Policy (CSP) annually awards the Bernard Brodie Prize to recognize “an outstanding article published in the journal in the previous year”. The award is named after the American military strategist Bernard Brodie (1910-1978), author of influential books such as The Absolute Weapon (1946), Strategy in the Missile Age (1959), Escalation and the Nuclear Option (1966), War and Politics (1973), and From Crossbow to H-Bomb (1973, with Fawn M. Brodie). As CSP acknowledges on its website, Brodie established “ideas that remain at the centre of security debates to this day”. Moreover, he was “one of the first analysts to cross between official and academic environments” and, importantly, Brodie “pioneered the model of civilian influence that CSP represents”. As Brodie underlined, for instance in War and Politics (1973): “the civil hand must never relax, and it must without one hint of apology hold the control that has always belonged to it by right.” On November 29, the journal announced its shortlist for the 2023 Bernard Brodie Prize and our open access article “Unintended Consequences of UN Sanctions: A Qualitative Comparative Analysis” (co-authored with Katharina L. Meissner, University of Vienna) was among those selected. The complete shortlist and a collection all previous prize winners can be found on the CSP website.

  • 26th Summer School in Social Science Methods, Lugano 2022

    From August 22-28, 2022 I taught at the 26th Summer School in Social Science Methods, organized by the Swiss Foundation for Social Science (FORS) and the Università della Svizzera Italiana (USI). The summer school is hosted at USI in beautiful Lugano, Switzerland. This was the fourth time I offered a one-week intensive course on Qualitative Comparative Analysis (QCA) at the Summer School in Lugano (after 2016, 2019, and 2021). This year, the course was offered as full-day in-presence workshop, with 18 participants hailing from 11 countries. The course was based on my QCA textbook Qualitative Comparative Analysis: An Introduction to Research Design and Application, published with Georgetown University Press (2021, Publisher’s Website). Many thanks to all course participants for an intensive and fun week with QCA! And thanks to School Coordinator Janice Casarella and the School Directors Benedetto Lepori, Eugène Horber, and Patrick Gagliardini for the excellent and smooth organization!



  • Open Access Article Published in Global Studies Quarterly

    The July 2022 edition of ISA’s new open access journal Global Studies Quarterly features our article “When Do International Organizations Engage in Agency Slack? A Qualitative Comparative Analysis of United Nations Institutions” (with Eugénia Heldt, Anna Novoselova, and Omar Ramon Serrano Oswald). The article is based on research from our German Research Foundation project on “International Bureaucracies and Agency Slack” under DFG project number 370183851. Our study examines 16 UN organizations and the organizational characteristics under which agency slack occurs at these IOs, based on a qualitative coding of primary documents from the UN Joint Inspection Unit.

    Abstract: The extensive delegation of power to international organizations (IOs) has been accompanied by occasional agency slack. While prior studies suggest that IOs’ propensity for agency slack may be rooted in their organizational characteristics, this has rarely been explored empirically. To address this lacuna, in this article we propose a conceptualization and measurement of agency slack and develop a framework of organizational characteristics. Our empirical analysis applies qualitative comparative analysis to assess the conditions under which agency slack occurs across sixteen United Nations institutions. We complement the cross-case analysis with two case illustrations. Our results document the empirical existence of two paths to agency slack, providing confirmatory evidence for our theoretical expectations. Path 1 combines staffing rules that are favorable for the agent with wide access to third parties. Path 2 entails the combination of favorable staffing rules with extensive delegation of authority and a vague organizational mandate.

  • Incentives and Constraints – Corrigendum

    The European Political Science Review issued a correction for the article “Incentives and Constraints: A Configurational Explanation of European Involvement in the Anti-Daesh Coalition“, originally published on February 24, 2022. The original publication contained erroneous illustrations. The correct versions of Table 1, Table 3, Table 4, and Table 5 are entailed in the corrigendum.



  • Podcast: Security Cooperation in the Global North and Russia’s War against Ukraine

    For the latest edition of The Bulletin Podcast I was invited to talk about Russia’s war against Ukraine and its implications for security cooperation in the global north. Thanks to Smriti Rai and Jesus Renzullo for their probing questions and the constructive conversation! The Bulletin Podcast is a blog and podcast series run by the Willy Brandt School of Public Policy at the University of Erfurt. In 2018, I already had the pleasure to contribute to its inaugural session, when I was Interim Franz Haniel Professor of Public Policy at the University of Erfurt (the 2018 session can be accessed here).

  • Guest Talk at West Point

    On April 13, 2022 I gave a virtual guest talk on “QCA in International Security” at the Social Science Research Lab, Department of Social Sciences of the United States Military Academy at West Point. In recent years, QCA has seen an increasing number of empirical applications on security-related topics, and IR research at large. In my talk, I gave a concise introduction to the method and its application in the field, outlined the structure of my QCA textbook, and provided an illustration of how QCA has been used to analyze coalition defection in the Iraq War. Thanks to Jordan Becker, Director of the Social Science Research Lab, and his colleagues for the invitation and the fruitful discussion after the talk!


  • Open Access Article Published in Contemporary Security Policy

    Contemporary Security Policy published our open access article “The Unintended Consequences of UN Sanctions: A Qualitative Comparative Analysis” (with Katharina L. Meissner, Centre for European Integration Research, University of Vienna). The article examines the flip-side to sanctions, namely their unintended consequences. Empirically, we draw on data from the Targeted Sanctions Consortium to conduct a set-theoretic analysis. We complement the QCA part with case illustrations on Haiti and North Korea.

    Abstract: Sanctions are widely used foreign policy tools in reaction to crises in world politics. Accordingly, literature on sanction effectiveness—their intended consequences—is abundant. Yet, fewer studies address the unintended consequences of restrictive measures. This is remarkable given that negative externalities are well documented. Our article explores this phenomenon by asking under which conditions sanctions yield negative externalities. We develop a theoretical conceptualization and explanatory framework for studying the unintended consequences of UN sanctions. Empirically, we draw on data from the rich, but scarcely used Targeted Sanctions Consortium and apply qualitative comparative analysis (QCA) to examine negative externalities of UN sanctions, complemented by illustrations from the cases Haiti and North Korea. The results document the existence of multiple pathways toward unintended consequences, highlighting the negative impact of comprehensive and long-lasting sanctions, as well as the ability of autocratic targets with economic means to persist unscathed from sanctions.

  • YouTube Book Summary

    The COMPASSS Network made some material from the last QCA Expert Workshop at ETH Zurich available on YouTube. This includes a 20-minute summary and some Q&A on my book Qualitative Comparative Analysis: An Introduction to Research Design and Application (Georgetown UP, 2021). This part starts in minute 12 of the recorded session (see the video link below).
