With data from the U.S. Census Bureau's American Community Survey, we estimate the effect of a large-scale, government-owned broadband network in Chattanooga, Tennessee, on labor market outcomes. Difference-in-Differences, augmented with Coarsened Exact Matching, is used to estimate the causal effect of the network across nine labor market outcomes. We find no economically- nor statistically-significant effect on the labor market from the city's broadband investments.
