Dr Stéphane Straub, Chief Economist for Infrastructure at the World Bank Group, recently spoke to Paddy Carter, Director, Development Impact Research and Policy at BII about his latest research
This event was organised by the Private Sector Development Research Network and hosted by British International Investment.
ABOUT THE RESEARCH
The paper that will be discussed during this session presents a meta-analysis of the infrastructure research done over more than three decades, using a database of close to a thousand estimates from 201 papers conducted between 1983–2022, reporting outcome elasticities. The analysis casts a wide net to include the transport, energy, and digital or information and communications technology sectors and the whole set of outcomes covered in the literature, including output, employment and wages, inequality and poverty, trade, education and health, population, and environmental aspects. The results allow for an update of the underlying parameters of interest, the “true” underlying infrastructure elasticities, accounting for publication bias, as well as for heterogeneity stemming from both study design and context, with a particular focus on policy relevant subsectors and developing countries.
