This project is especially meaningful: 14 years ago, I was part of the team, led by Víctor Rodríguez Hilario and @sdiazg, that helped design and implement the regulation. It’s gratifying to now contribute evidence on its impact. #Telecom #PublicPolicy #Regulation #EconTwitter

We find the regulation reduced Telcel’s share in prepaid lines, suggesting improved market competition. But interestingly, Telcel gained share in the postpaid segment, likely due to customer service improvements driven by the regulation's obligations.

We found that among all US reservations in the American Southwest in the early 20th century, those that had extensive contact with missions had a higher percentage of Catholics, lower crime rates, higher yields in agriculture, and earned income at a higher rate.

or that missions did not affect internal beliefs and norms of Native Americans. This view is certainly off base.

For all Native Americans the demographic impact of imperialism was devastating. Population fell by over 50%. Yet the conventional wisdom in much of the Southwest that Native American communities did not survive Spanish imperialism into the US period,
