When Disaster Strikes, Migrants Send Help

Following a disaster affecting 10% of a country’s population, an individual’s propensity to send remittances-quantified as a “remittance score” $\theta$-exhibits a discernible trajectory over 12 months, while the probability of continued remittance sending in the four months following the event is significantly modulated by the individual’s pre-disaster sending behavior.

New research reveals a significant surge in international remittances following natural disasters, demonstrating a critical yet often overlooked role in immediate disaster relief.
