Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...

Europe, We Have a Problem! Local Economic Winners and Losers of Border Closures
ABSTRACT In response to COVID‐19, Schengen countries temporarily reintroduced internal border controls, disrupting cross‐border integration. Using this policy change as a natural experiment and monthly nighttime lights data, we estimate the short‐run effects on European municipalities.

Urbanization and Spillover Effect for Three Megaregions in China: Evidence from DMSP/OLS Nighttime Lights [PDF]
Urbanization drives human social development and natural environmental changes and shows complex implications for sustainability and challenges of future development, particularly in emerging countries. While extensive studies focus on extracting urban areas more precisely, less attention has been devoted to understand megaregion evolution and its ...

Disasters, Dictators, and Donors: The Impact of Foreign Aid on Economic Activity (Mis)Reporting
ABSTRACT This paper examines how governments manipulate economic data to secure more foreign disaster aid. By using nighttime lighting as a reliable measure of economic activity, we make two key findings: (1) foreign disaster aid is positively linked to a country's understatement of its gross domestic product, indicating a deliberate strategy to ...

Subnational Border Reforms and Economic Activity in Africa
ABSTRACT Using GIS methods, we identify territories in Africa affected by subnational border reforms between 1992 and 2013. Descriptive statistics reveal that these territories differed from other African regions across several key dimensions. For example, these territories were more populous and exhibited greater ethnic diversity.
