The Journey to Work and Gender Inequality in Earnings: A Cross-Validation Study for the United States

Abstract

It has been well documented that women tend to work closer to home than men. One interpretation of this finding has been that women face more spatially constrained labor markets than men, and these constraints are thought to be a factor in the gender gap in earnings. A recent study of Tel Aviv, Israel, by Moshe Semyonov and Noah Lewin-Epstein (1991) also found that working women clearly tend to hold employment more in the vicinity of their homes than do men. The observed deficits in earnings by employed women were thought to be exchanged for compliance with traditional gender-role expectations. Our study cross-validates key portions of the Semyonov and Lewin-Epstein study for the United States by examining the location of labor markets and their relationship to gender inequality in earnings in the 1988 wave of the NLSY panel database. Using annual earnings as the dependent variable and other similarly defined variables, we parallel their multiple regression analysis. The time-to-work reports of NLSY panel members are used to assess their commuting behavior and the results of this analysis are compared across four types of residential locations: rural, small urban, suburban, and large central city. We modestly confirm the gender inequalities in earnings produced by differential commuting behaviors for men and women but cannot fully generalize them to a broad set of residentially defined labor markets. For instance, women in suburban settings do have a higher return in earnings from time spent commuting but this effect is not significantly higher than the same returns for suburban men. A somewhat surprising negative effect of commuting time on the earnings of suburban women and men was also observed. We suggest further research on this problem involving the “perceived constraint” hypothesis to explain the commuting gap between men and women.
