A lot of the insight in this paper seems pretty obvious when given any thought. > Households that leave harbinger zip codes tend to go to other harbinger zip codes. Since they also claim that house prices in harbinger zip codes increase less than other areas, then this just sounds like people from poor areas moving to other poor areas. > The findings indicate that harbinger zip codes are less likely than other zip codes to donate to the candidates who receive the most donations in their three-digit zip code. There can be huge differences between two areas with the same three-digit zip codes. A rural or suburban area can easily have the same three-digits as a downtown urban area. It would make sense for a people in two starkly different areas to support different political candidates and for the candidate supported by the more populous urban area to win.
