We have a particularly special edition of CPR Perspectives – our flagship interview series commemorating the Centre for Policy Research’s 50th anniversary. This month officially marks 50 years since the Centre was founded, back in 1973, as an institution that would work to produce field-defining research and vital policy insights relevant for both the country’s decision-makers as well as an informed public. To mark the occasion, this edition of CPR Perspectives features a conversation with Yamini Aiyar, President and Chief Executive of the Centre for Policy Research. As with previous episodes in the series, we touch upon Aiyar’s path to CPR – including how she entered the Indian policy ecosystem with stints at Udyogini, a grassroots NGO, the Ford Foundation and the World Bank. But the bulk of the conversation takes a broader look at the history of CPR, the vital role it has played in key Indian policy debates – from industrial policy and economic liberalisation to foreign policy and climate change – and the challenges it is currently confronting. Aiyar joined CPR in 2008, when she founded the Accountability Initiative, a research project that oversaw one of India’s largest expenditure tracking surveys for elementary education and brought a deeper, evidence-based understanding of public service delivery to the policy conversation in India. In 2017, Aiyar took charge as President and Chief Executive of the Centre for Policy Research, overseeing the deepening and expansion of the institution's research efforts and a broadening of its engagement with governments, grassroots organisations and the global policy community. She also continued her own research on public welfare, federalism and state capacity, while serving on a number of government and international policy committees.
