David Zipper, a Visiting Fellow at the Harvard Kennedy School's Taubaman Center for State and Local Government writes:

For years, leading academics have argued that any employer, big or small, stands to benefit from an improved transportation network that shortens commutes. After all, a CEO may situate her headquarters in a location convenient to her home, but her company’s productivity — and its competitiveness — is largely determined by the quality of its workforce. And that workforce will be of a lower quality if arduous commutes deter a chunk of the local labor market from even considering jobs in a given location.
