I wonder if there's some model that could explain it using static friction. If you and everyone around you is and has been at the same socio-economic situation for a long while, it would take something big to make you move, but if you have just immigrated, then obviously there's no static friction and you don't have any particular baseline anymore, so you have a higher likelihood of just keeping in motion, due to the lower dynamic friction.
