United Nations University World Institute for Development Economics Research (UNU-WIDER)
UNU-WIDER is one of 13 research and training Institutes that comprise the think tanks in the UNU system.
UNU-WIDER is a leading international development economics think tank. The Institute provides economic analysis and policy advice with the aim of promoting sustainable and equitable development for all. The Institute began operations in 1985 in Helsinki, Finland, as the first research centre of the United Nations University. Today, it is a unique blend of think tank, research institute, and UN agency โ providing a range of services from policy advice to governments, as well as freely available original research. More information on UNU-WIDER and its current work programme are available at www.wider.unu.edu.
UNU-WIDER is implementing a large research, capacity development, and policy engagement programme in South Africa, called Southern African โ Towards Inclusive Economic Development (SA-TIED) in close collaboration with the National Treasury of South Africa. Building on the successful first phase of this programme, phase II of SA-TIED will continue to bring together world class researchers with policymakers to combat socio-economic challenges in South Africa but also in the broader southern African region. A big focus of SAโTIED relates to its engagements with the policyโmaking community as a partner. A key aspect of the programme is to generate robust empirical evidence and use it as a basis to encourage networking and discussion amongst people involved in policy processes across the participating organisations and civil society to bridge the gap between research and policyโmaking. The programme played an important part in making anonymised administrative tax data available for research purposes at a Secure Data Facility at the National Treasury (NT-SDF) and is a key asset in the programme. The availability of administrative tax data for research has enabled many new avenues of research and has provided new perspectives on the South African economy and has dramatically improved the quality and breadth of evidence used to inform policy. For more information on SA-TIED, please visit https://sa-tied.wider.unu.edu/.
