To address the overall objectives, this EU-funded NestIOr project combines statistical research on many IOs with in-depth case studies of how IOs address existential challenges. Much research effort has gone into expanding existing datasets on IOs with relevant institutional design features to study whether the institutional design affects the survival of IOs. By manually going through the treaties of 150 different IOs since 1815, we have uncovered original data on how flexible IOs are. For instance, whether the treaties of IOs allow for the withdrawal of member states, whether member states vote on policies or take decisions by consensus, and to what degree the mandates of IOs are fixed. We have furthermore uncovered new data on the bureaucratic capacities of IOs, such as how many staff members are working for the different 150 IOs. These unique new data have allowed us to statistically analyse the effects of institutional design on whether IO are repeatedly criticized, face withdrawals by member states, and survive longer.
We have combined this statistical analysis of many IOs with in-depth case studies of individual IOs. Case studies are helpful as they allow us to zoom in on the specific context in which IOs operate. We have studied, in this respect, a number of challenges to IOs in depth. For instance, how the European Commission has responded to the UK withdrawal negotiations since 2016. We have also looked at how NATO, the World Trade Organization, and the UN Framework Convention on Climate Change have differently reacted to challenges by President Donald Trump. And we have studied the effect of competing IOs, such as the competition of the EU and NATO in the area of security, the International Energy Agency and the International Renewable Energy Agency, and the World Bank and the Asian Infrastructure Investment Bank. The focus for the case studies has been the institutional design features that have helped IOs to respond to external challenges. What makes the case study research unique is that we have conducted around 140 interviews with key policy makers in various IOs. As such, the project offers a behind-the-scenes perspective of the decline and survival of IOs.
We have published the results in a large number of journals articles, a research monograph as well as three PhD dissertations. Throughout these publications, which deal with individual IOs as case studies or compare processes across different IOs or present the results of large quantitative comparisons, we find that the institutional features of IOs greatly matter for their survival. In particular, their administrative resources in terms of staff are important. If IOs have sufficient staff resources, they are better at responding to large societal challenges. At the same time, our detailed case studies also show that IOs need sufficient leadership to address crises, a clear organizational structure, and IOs should be embedded in larger societal networks which also includes elites across the member states, NGOs, multinational companies, experts and other civil society actors. IO staff members cannot operate any more alone if they want their organizations to prosper.
