The attack on the World Trade Center had an enormous financial, as well as emotional, impact on New York City. This article measures the short-term economic effects on the city’s labor force and capital stock through June 2002, the end of the recovery process at the World Trade Center site. Using a lifetime-earnings loss concept, the authors estimate that the nearly 3,000 workers killed in the attack lost $7.8billion in prospective income. Moreover, the employment impact in the key affected sectors—such as finance, air transportation, hotels, and restaurants—translated into an estimated earnings shortfall of $3.6billion to $6.4billion, while the cost of repairing and replacing the damaged physical capital stock and infrastructure totaled an estimated $21.6billion. Accordingly, the authors determine that the total attack-related cost to NewYorkCity through June 2002 was between $33billion and $36billion. The article also examines the attack’s effects on the city’s most economically vulnerable residents and analyzes survey findings on the incidence of post-traumatic stress disorder and alcohol and drug use after September11.
