We investigate the impact of early internet availability at basic speeds on local economic development in remote areas of developing countries by analyzing nighttime light emissions across towns in Sub-Saharan Africa. Using a difference-in-differences approach, we exploit submarine cable arrivals, which established countrywide internet connections, and the rollout of the national backbones, which defines internet access within countries. Estimating on incidentally connected mid-sized towns, we find that early internet availability increases nighttime light intensity by 10 percent. We consider increased employment as the main explanation. Our findings highlight the importance of closing the digital divide for regional development.
This study investigates the economic impact of China’s “stadium diplomacy” in Sub-Saharan Africa. Exploiting the staggered timing of the construction in a difference-in-differences framework, we analyze the effect of Chinese-built and financed stadiums on local economic development. Employing nighttime light satellite data, we provide both an aggregate and spatially disaggregated assessment of these investments. We find that a stadium's city nighttime light intensity increases by about 24 percent, on average, after stadium completion. The effects can be attributed to the stadiums but are not only visible close to the stadium's location. Estimates on nighttime light activity are mirrored by individual-level employment effects in the stadiums’ surrounding area. For stadiums not built or financed by China, we cannot find similar effects. Our results contrast with the widely held notion that China’s development finance projects constitute “white elephants”.
