The commonly-used satellite images of nighttime lights fail to capture the true brightness of most cities. We show that night lights are a reliable proxy for economic activity at the city level, provided they are first corrected for top-coding. We present a stylized model of urban luminosity and...

Satellite data on nighttime luminosity is an increasingly popular proxy for economic activity in developing countries. However, their use for analyzing inequality and convergence on a global scale is severely limited by top-coding of the NOAA satellite images, which fail to accurately capture...

Similar looking Lorenz Curves can imply very different income density functions and potentially lead to wrong policy implications regarding inequality. This paper derives a relation between a Lorenz Curve and the modality of its underlying income density: Given a parametric Lorenz Curve, it is...
