Recalculating - How Uncertainty in Local Labor Market Definitions Affects Empirical Findings
Foote, Andrew; Kutzbach, Mark J.; Vilhuber, Lars
This paper evaluates the use of commuting zones as a local labor market definition. We revisit Tolbert and Sizer (1996) and demonstrate the sensitivity of definitions to two features of the methodology. We show how these features impact empirical estimates using a well-known application of commuting zones. We conclude with advice to researchers using commuting zones on how to demonstrate the robustness of empirical findings to uncertainty in definitions.
