  Title A sharper image? Estimates of the precision of nighttime lights as a proxy for economic statistics Type Journal Article
  Year 2014 Publication Journal of Economic Geography Abbreviated Journal J of Econ Geog  
  Volume 15 Issue 1 Pages 217-246  
  Keywords Nighttime lights; luminosity; output measurement; national accounts; proxy measures; social science; economics; remote sensing  
  Abstract Much aggregate social-science analysis relies upon the standard national income and product accounts as a source of economic data. These are recognized to be defective in many poor countries, and are missing at the regional level for large parts of the world. Using updated luminosity (or nighttime lights) data, the present study examines whether such data contain useful information for estimating national and regional incomes and output. The bootstrap method is used for estimating the statistical precision of the estimates of the contribution of the lights proxy. We conclude that there may be substantial cross-sectional information in lights data for countries with low-quality statistical systems. However, lights data provide very little additional information for countries with high-quality data wherever standard data are available. The largest statistical concerns arise from uncertainties about the precision of standard national accounts data.

  Title Measuring the impact of insurance on urban earthquake recovery using nightlights Type Journal Article
  Year 2019 Publication Journal of Economic Geography Abbreviated Journal  
  Volume in press Issue Pages lbz033  
  Keywords Remote Sensing; Earthquakes; New Zealand; Night lights  
  Abstract We measure the longer-term effect of a major earthquake on the local economy, using night-time light intensity, and focus on the role of insurance payments for damaged residential property in the recovery process. The destructive Canterbury Earthquake Sequence (2010–2011) in New Zealand is our case study. Uniquely, for this event, >95% of residential housing units were covered by insurance and almost all incurred some damage. However, insurance payments were staggered over 5 years, enabling us to identify their local impact on recovery. We find that night-time luminosity can capture the process of recovery; and that insurance payments contributed significantly to the process of local economic recovery after the earthquake. Cash settlement of claims was no more effective than insurance-managed repairs in generating local recovery. Notably, delayed payments were less affective in assisting recovery; this suggests an important role for the regulator in making sure insurance payments are made promptly after disaster events.
