In African cities, small firms locate on busy roads to attract customers and increase profits. Vittorio Bassi, Matthew E. Kahn, Nancy Lozano Gracia, Tommaso Porzio, and Jeanne Sorin show how this exposes workers to substantial air pollution.

In Brazil, Ridwan Karim highlights how tackling voter fraud not only protected election integrity, but also enhanced political accountability, improved leadership quality, and promoted better governance outcomes.

In this week’s two-part VoxDevTalks special, Francis Annan discusses his extensive research on mobile money markets in Ghana, as well as his personal experience partnering with businesses—and eventually policymakers—on this research.

Andrea Matranga and Timur Natkhov discuss how this hardwired coercion into law and shaped Russia’s long-term institutional landscape.
