Abstract
Satellite-detected night lights data are widely used to evaluate economic impacts of sanctions. Such data should be free from political manipulation. However, measurement errors in these data, from blurring and bottom-coding, are rarely considered. To study such errors, we use a difference-in-differences analysis of impacts of closing the Kaesong Industrial Zone in North Korea—a sanction South Korea imposed in 2016. Luminosity in the affected region declined by a precisely estimated 50 percent. When using the popular Defense Meteorological Satellite Program (DMSP) night lights data the apparent impacts are imprecisely estimated and far smaller. Measurement errors in DMSP data may distort evaluations of sanctions.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
