This paper investigates the determinants of skyscraper height. First a simple model is provided where potential developers desire not only profits but also social status. In equilibrium, height is a function of both the costs and benefits of construction and the heights of surrounding buildings. Using data from New York City, I empirically estimate skyscraper height over the 20th century. Via spatial regressions, I find evidence for height competition, which increases during boom times. In addition, I provide estimates of which buildings are economically “too tall” and by how many floors.
