Trumpin muurihanketta kritisoitiin väittäen, ettei se vähennä siirtolaisuutta.
Nyt on tiedonjanoisilla syytä iloon. Enää ei tarvitse luottaa mutuiluun, sillä Yhdysvaltojen Meksikon vastaisen rajan raja-aitojen vaikutusta siirtolaisuuteen on tutkittu.
Tutkimuksen mukaan aitojen rakentaminen vähentää siirtolaisuutta Meksikosta Yhdysvaltoihin.
This paper estimates the impact of the U.S.-Mexico border fence on U.S.-Mexico migration by exploiting variation in the timing and location of U.S. government investment in fence construction. Using Mexican survey data and data I collected on fence construction, I find that construction in a municipality reduces migration by 27% for municipality residents and 15% for residents of adjacent municipalities. In addition, construction reduces migration by up to 35% from non-border municipalities. I also find that construction induces migrants to substitute towards alternative crossing locations, disproportionately deters low-skilled migrants, and reduces the number of undocumented Mexicans in the United States.

My analysis demonstrates that fence construction significantly reduces migration from Mexico to the U.S
