While international cooperation research emphasizes institutional design,
states mostly interact with existing organizations. How do states choose organizations
for cooperation? We develop a theory of agency choice for development projects,
emphasizing the importance of domestic institutions, the scope of cooperation, and
the resources of the implementing agency. If states are to cooperate with funding
agencies that have abundant resources, such as the World Bank, they must accept
more stringent conditions on project implementation. We argue states accept the
stringent conditions that resourceful organizations demand if the public goods from
project implementation are highly valuable. Empirically, this is the case for democratic
states, large projects, and projects that produce national instead of global public
goods. We test this theory using data on 2,882 Global Environment Facility (GEF)
projects, 1991–2011. The GEF offers an ideal case because various implementing
agencies are responsible for the actual projects. States implement projects in collaboration
with the World Bank, which has the most expertise and resources among
the GEF’s implementing agencies, if their regime type is democracy, the project size
is large, and the benefits are primarily national. Qualitative evidence sheds light on
causal mechanisms
