OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Public R&D Meets Economic Development: Embrapa and Brazil’s Agricultural Revolution
Can public R&D investment in developing countries drive productivity growth? We study this question in the context of Brazilian agriculture and the Empresa Brasileira de Pesquisa Agropecuária (Embrapa), a public research corporation established in 1973 to develop locally suitable science and technology. First, we show that Embrapa redirected research toward prioritized staple crops and local ecological conditions, and increased research productivity, especially in remote and research-scarce regions. Second, exploiting the staggered rollout of research centers alongside heterogeneous local exposure to Embrapa’s technology development, we find that Embrapa significantly increased agricultural output, driven both by higher productivity and expanded input use. Combined with a model, these estimates imply that public R&D investment increased national agricultural productivity by 110% with a benefit-cost ratio of 17. The decentralized structure, in which research labs were spread across many ecological zones instead of in a single hub, explains a large share of these benefits.
