Networks and Inequality

Networks and Race

Racism in America

  • Overt, animus-based racism has declined a lot

But racial inequality is still dramatic

But racial inequality is still dramatic

There is a lot of research on the causes

  • Overt social, economic, and institutional racism existed until the 1960s
    • Slavery, Jim Crow, Redlining, GI Bill, etc.
  • This left black Americans with less wealth, worse jobs, worse schools, etc.
  • Our system makes some of these inequalities self-reinforcing
    • E.g., school funding

Social Capital is an underappreciated cause

  • Social capital is our ability to access resources through our social networks
  • Social networks are highly segregated, and so even without overt racism, people of color have less access to social capital
  • This can include access to mentors, jobs, etc. but also money to handle unexpected expenses or to invest in a small business
  • We can see other inequalities, but social capital is often invisible

Networks matter a lot

  • In the 90s, people were given vouchers to move to lower poverty areas
  • Chetty at al. found that children did better as adults the longer they lived in higher income / higher mobility areas
    • Why? One (the best!) explanation is that people gain greater social capital

Follow up study in 2022

  • Measured a few markers of social capital
  • Most important predictor of upward mobility was high “economic connectedness” of where you lived
  • Economic connectedness was measured as the proportion of high-income people that low-income people were connected to in the area

Follow up study in 2022

Takeaways

  • Networks provide a hidden inertia to society, reproducing the world as it is
  • Differences in economic capital or cultural capital are more visible
  • Our achievements are partially a function of our undeserved social networks
  • Worth thinking about “network equality”
