It exploits spatial and temporal variation in road upgrades across Ethiopia, together with high-resolution panel data derived from satellite imagery. The findings show that road upgrades contributed to increases in local economic activity, as proxied by nighttime lights and urban land area. However, there is significant heterogeneity in the results across baseline levels of economic activity. Specifically, gains from road upgrades are concentrated in areas with moderate-to-high initial levels of economic activity. By contrast, there was little, or even negative, growth in areas with low levels of initial economic activity. Finally, the findings show that road upgrades contributed to a reduction in cropland in areas with medium-to-high baseline nighttime lights. The results suggest that Ethiopia's ambitious road infrastructure development program overall increased local economic activity and urbanization, but that it also had important distributional implications that need to be taken into account when planning such infrastructure programs.","geographic_units":[{"name":"Ethiopia","code":"ETH","type":"cty"}],"topics":[{"id":"R4","vocabulary":"JEL Classifications","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php","name":"Transportation Economics"},{"id":"R12","vocabulary":"JEL Classifications","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php","name":"Size and Spatial Distributions of Regional Economic Activity"},{"id":"R14","vocabulary":"JEL Classifications","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php","name":"Land Use Patterns"}],"language":[{"name":"English ","code":"EN"}],"data_statement":"All data is public, but due to its size not contained in the reproducibility package.","methods":[{"name":"Differences-in-Differences(Did)","note":" We use the method proposed by Callaway and Sant\u2019Anna (2021) that is designed for applicationswith multiple time periods and where the timing of treatment varies across units."},{"name":"Long-difference approach","note":"focuses on the benefits of the program for incidentally treated areas compared to the areas that did not benefit from the program.
