The biggest obstacle to locating any business outside of Manhattan is the transit system. Most subway lines run between the outer boroughs and Manhattan, and the regional commuter railroads (LIRR, NJ Transit, PATH and Metro North) all terminate in Manhattan (or primarily in Manhattan, since LIRR also has stations in Brooklyn and Queens). Thus, locating a business outside of Manhattan greatly reduces the area from which it can recruit employees.
