Using economic data collected from 24 different Metropolitan Statistical Areas in the US, this thesis investigates the impact of constructing a new National Basketball Association (NBA) arena on the host city’s economy. When a simplistic model is implemented, which does not control for other economic factors or individual subject heterogeneity, significantly positive economic impacts of arena construction are observed. However, when a more appropriate model specification is implemented that controls for economic activity and individual heterogeneity, these effects are no longer statistically significant. This comparative analysis ultimately highlights the importance of appropriate model specification and supports the conclusion that new NBA arenas, by themselves, are not significant catalysts of urban economic development.
