Secularity and migration aspirations in the Arab world

Hajare El Hadri, Réda Marakbi


World Development - 2025-12

This study develops a new theoretical framework to explain how secularity influences migration aspirations in the Arab world. We argue that secular individuals incur significant psychological costs when living in highly religious societies. This value incongruence pushes them to seek out more secular environments, whereas strongly religious individuals face higher cultural costs of moving and thus prefer to stay. We derive testable hypotheses on how individual secularity and socio-political secularity act as push pull factors for different communities and migration destinations. We then test these hypotheses using 2018 2019 Arab Barometer data from eleven MENA countries. We construct original indices for individual secularity and socio-political secularity via multiple correspondence analysis. Consistent with our theory, probit and instrumental-variable probit estimates show that secular individuals are significantly more likely to express intentions to emigrate particularly to highly secular Western countries. Among Muslim majority populations, both individual and socio-political secularity increase the desire to migrate, whereas among Christian minorities only individual secularity has this effect. Moreover, secularity drives regular migration aspirations, with no measurable impact on irregular migration except in the case of religiously unaffiliated “nones,” who exhibit a heightened willingness to migrate by any means. These findings contribute to the migration literature by emphasizing the substantial, yet previously underexplored, influence of secular beliefs and practices on migratory behavior in the Arab context.

Environmental policy stringency and firm efficiency in developing countries

Bao We Wal Bambe, Jean-Louis Combes, Ben-Vieira Kouassi, Sonia Schwartz


Small Business Economics - 2025-11-22

Abstract This article examines the impact of environmental stringency on firm efficiency, using a large cross-country dataset of 68 developing countries from 2006–2020. We combine the newly published Environmental Performance Index (EPI) as an indicator of the stringency of environmental regulations with firm data from the World Bank Enterprise Surveys (WBES). Our results indicate that stricter environmental policies significantly increase firm efficiency, and the effect is robust. Moreover, we find that the intensity of environmental stringency matters, and that firm size, firm pollution intensity, and institutional quality also influence the relationship between environmental stringency and efficiency. Thus, our results support the Porter hypothesis in the case of developing countries.

Artisanal mining in Africa. Green for Gold?

Victoire Girard, Teresa Molina-Millán, Guillaume Vic


The Economic Journal - 2025-11-21

The livelihoods of 130 to 270 million people depend on artisanal mining. Artisanal mining is a labour-intensive, often illegal, extractive activity. We combine geological knowledge and a source of exogenous temporal variation to construct the first proxy for artisanal gold mining in Africa—the main form of artisanal mining. We establish that an increase in the potential value of artisanal mining is a significant driver of deforestation. The historical increase in the gold price accounts for 8% of forest loss across the continent and, within the subset of gold-suitable areas, 28 %. In parallel, artisanal mining increases local economic wealth and may provide an alternative livelihood should a weather shock jeopardise agricultural output. Finally, mining-induced deforestation seems rooted more in the direct clearing of trees for the activity than in indirect deforestation triggered by increased local demand.
