Environmental drivers of migration attract more and more attention. This article focuses on the effect of fish stock depletion on migration in Africa and uses a novel dataset on fishing intensity (Kroodsma et al., 2018). Based on a panel of the 37 African countries with access to the sea over the...

The measurement equation captures the error in estimating log densities from repeated cross-sectional samples...
