Transit Infrastructure and Couples’ Commuting Choices in General Equilibrium

What is the impact of improving the transit infrastructure on the gender earnings gap? How does family structure matter to un‐derstand the impact of new transit infrastructure? Recent mod‐els on spatial economics hinge on the assumption that house‐holds are comprised of a single type of person making commut‐ing and location choices. In reality, an important share of the pop‐ulation lives in households with more persons, whose commut‐ing choices might be interlinked through the household’s budget constraint. I set up and estimate a quantitative model of city structure featuring single and married households leveraging on the introduction of a Metro line and the Bus Rapid Transit System (BRT) in Lima, Peru. My model delivers interdependent commut‐ing choices within dual‐earner households. This way, reduced commute times impact one partner’s commuting patterns not only by affecting her prospects, but also those of her spouse. I show that this mechanism is quantitatively important. If I ignore this mechanism, I would overestimate gains in real income by 11% and underestimate reductions in the gender earnings gap by 103%, leading to a switch in the sign of the impact of the Metro and the BRT.
