A Case for a New Satellite Mission for Remote Sensing of Night Lights
Remote Sensing, 2021 The physiology and behavior of most life at or near the Earth’s surface has evolved over billions of years to be attuned with our planet’s natural light–dark cycle of day and night.

Disasters, Dictators, and Donors: The Impact of Foreign Aid on Economic Activity (Mis)Reporting
Review of Development Economics, EarlyView.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 ...

Tracking Electrification in Vietnam Using Nighttime Lights
Remote Sensing, 2014 We report on a systematic ground-based validation of DMSP-OLS night lights imagery to detect rural electrification in Vietnam. Based on an original survey of village-level units in Vietnam, this study compares nighttime light output from the U.S.

The Political U: New Evidence on the Economic Costs of Hybrid Regimes
Economics &Politics, Volume 38, Issue 3, Page 747-769, November 2026.ABSTRACT Recent research establishes a positive causal effect from democracy to income, although this evidence relies mostly on binary regime classifications. We extend the identification framework of Acemoglu et al. (2019) to a classification that distinguishes democracies, autocracies, and hybrid regimes for about 170 countries over 1960–2024.

Subnational Border Reforms and Economic Activity in Africa
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 5, Page 1203-1218, October 2026.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.

The Declining Trend of Arctic Sea‐Ice Extent (1979–2025): Segmented by Abrupt Change Points
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Arctic sea‐ice extent (SIE), a high‐accuracy observable, is a key indicator for assessing sea‐ice state and its physical evolution. Extreme SIE losses thus often spark debates over potential Arctic tipping behavior and nonlinear threshold responses.

PROGRESS FOR STABLE ARTIFICIAL LIGHTS DISTRIBUTION EXTRVCTION ACCURACY AND ESTIMATION OF ELECTRIC] POWER CONSUMPTION BY MEANS OF DMSP/OLS NIGHTTIME IMAGERY [PDF]
, 2010 The Noise Reduction Filter (NRF) that is developed by the authors is applied to extract artificial nightlight components of a time series DMSP/OLS-VIS dataset. High frequency components from the time series DMSP/OLS-VIS dataset are exhausted and a direct
