Abstract
This paper estimates welfare gains using detailed data from a public transport subsidy experiment in Bogotá, Colombia. The effective experimental variation in subsidy allocation allows the identification of key parameters in a discrete choice model, resulting in credible estimates of welfare gains for the beneficiaries of the intervention.
The program increased participants’ average monthly welfare, measured as consumer surplus, while the magnitude of those gains differed meaningfully across trip purposes and travel-time constraints. The project sits at the intersection of development economics, urban economics, and transport policy, and it continues to shape my broader research agenda on mobility and access.
