Replication Studies of Development Impact Evaluations

Six years ago, the International Initiative for Impact Evaluation (3ie) launched a programme to promote and fund replication studies of impact evaluations in international development. We designed the programme with the objective of improving the quality of evidence for development policy-making, using replication research to both validate the results of published impact evaluations and build the incentives for more transparent and high quality research going forward. The programme’s focus is internal replication, which uses the original data from a study to address the same question as that study. This Journal of Development Studies special issue compiles the majority of completed 3ie-funded replication studies initiated in the first years of the programme. In all cases the pure replication components of these studies are generally able to reproduce the results published in the original article. Most of the measurement and estimation analyses confirm the robustness of the original articles or call into question just a subset of the original findings. These replication studies mostly focus on providing additional information about the impacts of the interventions – especially additional information that can be important for interpreting the articles for the purpose of policy-making.     

Gibraltar at the United Nations: Caught Between a Treaty,the Charter and the “Fundamentalism” of the Special Committee

On account of Spain's long-standing claim to the sovereignty of the British Overseas Territory of Gibraltar, “the Rock” remains one of sixteen non-self-governing territories on the United Nations list awaiting decolonization. This article examines the principles of self-determination and territorial integrity adopted by the United Nations in consideration of the issue of decolonization as they have been applied to Gibraltar, together with the consequences for the parties concerned. With the fiftieth anniversary of the first United Nations Resolution on decolonization on the horizon and the recent adoption by Gibraltar of what is considered to be a non-colonial constitution, the article suggests that it is timely for the United Nations to consider taking a more flexible approach to Gibraltar's status that would put to one side Spain's claim but allow Gibraltar to be removed from the UN list.
