This paper proposes a new methodology for evaluating off-grid electrification projects, based upon Nighttime Light (NTL) observations, obtained by a combination of Defense Meteorological Satellite Program (DMSP) data and Visible Infrared Imaging Radiometer Suite (VIIRS) data. The methodology cons…
We analyze the domestic transport and logistics costs of importing a 20-foot container into Africa. We run regressions on a panel of 50 African countries for the period 2006–2014 using the RE-2SLS estimator. Distance from port of arrival to the point of delivery is an important explanatory factor…

Rabah Arezki and Grégoire Rota-Graziosi explore what the legacy of Covid-19 will be for our tax systems and several dimensions for the required rethinking.

La FERDI a mis au point une initiative originale pour évaluer l’impact et identifier les bonnes pratiques des projets d’accès aux services essentiels, en s’appuyant sur l’exemple des projets d’électrification décentralisée. Un grand nombre de résultats de travaux d’évaluation de tels projets a ét…
The question of how people revise their decisions about whether to emigrate, and where to, when facing changes in the global environment is of critical importance in migration literature. We propose a cross-nested logit (CNL) approach to generalize the way deviations from the IIA (independence fr…
