MORA TELLEZ, Ricardo. Duration of migratory trips of undocumented Mexicans in the United States under the border enforcement policy. Pap. poblac [online]. 2017, vol.23, n.94, pp.33-57. ISSN 2448-7147.  https://doi.org/10.22185/24487147.2017.94.031.

This article studies the effect of political border enforcement on the duration of the migratory journeys of undocumented Mexican migrants. In particular we analyze the effect of increase of the risks and costs of illegal border crossing that arise from this migration policy over the trip duration of undocumented migrants in the United States. For this purpose a logit model (Discrete-Time Hazard Model) was fit, which allows to determine changes in the odds of return and, therefore changes in trends in migratory journeys durations. The database used is the survey Mexican Migration Project (MMP). The model has negative coefficients on the variables costs and risks of clandestine border crossing in regard to the probability of return.
