Despite the sustained scholarly attention that the United Nations and international NGOs have received in the twenty-first century, they still remain under-researched from a management studies perspective. This volume brings together rich analyses of these organizations’ functioning, arguing that they are best understood as intermediaries between international decision-making and funding bodies in the developed world and initiatives that take place on the ground, primarily in the Global South. Based on current management research, this follow-up to Rethinking International Organizations (Berghahn, 2002) provides a wealth of both empirical and theoretical insights, along with practical recommendations how these organizations can function more effectively.
