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…

mars 2021 Fighting the soaring prices of agricultural food products – VAT versus Trade tariffs exemptions. A case study in Niger Stéphane CALIPEL, Céline DE QUATREBARBES, Bertrand LAPORTE

As happened in West Africa in 2008, in an imported inflation context, it is common for the governments to take short-term tax action to protect the poor: VAT or trade tariffs exemptions. As part of the tax-tariff transition, the comparison between Trade tariffs and VAT has already been the subjec…

février 2021 COVID-19’s ‘thundering’ effect on taxes Rabah AREZKI, Grégoire ROTA-GRAZIOSI

The COVID-19 crisis is an opportunity to renew the “social contract.” The disease reinforces the role of the state in protecting against health risk and in its social transfer programs to shield the citizenry against the economic consequences of the health crisis. COVID-19 has thus reasserted the…

février 2021 How export shocks corrupt: theory and evidence Joël CARIOLLE, Petros G. SEKERIS

In this article we uncover a positive effect of both export booms and busts on firm-level corruption. Our theory underlines the central role played by human capital in the underlying mechanism. In low human capital settings, export-related revenues are highly elastic to incremental gains of expor…

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…

janvier 2021 New York, Abu Dhabi, London or Stay at Home? Using a Cross-Nested Logit Model to Identify Complex Substitution Patterns in Migration Michel BEINE, Michel BIERLAIRE, Frédéric DOCQUIER

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…
