L7. Neighbourhood Effects (1)

ECN326 Urban Economics: Neighbourhood Effects

Instructor: Gwilym Pryce

Overview of Neighbourhood Effects

  • Importance of Location:

    • Analysis of how neighbourhoods affect various aspects of an individual's life, including:

      • Well-being (mental and physical health)

      • Educational development

      • Engagement in crime

      • Life outcomes, particularly employment

      • Social mobility

Case Study: Splott

  • Explores the implications of growing up in specific neighbourhoods.

  • Questions whether life outcomes would differ significantly if one had not stayed in Splott.

Impact of Childhood Neighborhood on Life Trajectory

  • Key Question:

    • How does the neighbourhood affect overall life trajectory?

    • Would life outcomes differ had one grown up in a different neighbourhood?

Segregation Topics

Part I: Ethnic Segregation

  1. Drivers of Ethnic Segregation

  2. Trends in Ethnic Segregation

  3. Impacts of Ethnic Segregation

Part II: Economic Segregation

  1. Drivers of Economic Segregation

  2. Trends in Economic Segregation

  3. Impacts of Economic Segregation

Drivers of Ethnic Segregation

Causes of Ethnic Segregation:

  1. Preference Drivers:

    • Homophily (voluntary self-segregation)

  2. Economic Drivers:

    • Inequities limiting choice for disadvantaged groups

  3. Organised Drivers:

    • State and strategic coordination of segregation

Preference Drivers

Symmetric and Asymmetric Preferences:

  • Symmetric Preferences:

    • Groups prefer living among similar groups (mirrored preferences)

  • Asymmetric Preferences:

    • Includes concepts like “White Flight” and social frontiers, which explains differing preferences across groups.

White Flight

  • Definition:

    • Movement of White middle-class families from urban areas in response to the migration of Black families during the 1950s and 1960s.

  • Evidence showed that each Black arrival led to an average of 2.7 White departures from the city (Boustan, 2010).

Geographic Focus on White Flight

  • White Flight observed predominantly in central cities, particularly in the USA.

  • Suggestion that similar patterns may emerge in UK and European cities at smaller spatial scales.

  • Neighbourhood definitions can vary by demographics and administrative boundaries.

Ethnic Density Effects on Wellbeing

Theory:

  1. Racism:

    • Influences ethnic inequalities in health.

  2. Ethnic Density Hypothesis:

    • Higher proportions of own ethnic groups enhance mental health due to community support and reduced exposure to discrimination.

Evidence:

  • Studies indicate a reduction in mental health issues associated with higher own ethnic density.

  • Protective effects such as enhanced social support and a strong community network.

Impacts of Economic Segregation

  1. Drivers:

    • Income inequality influences housing prices and neighbourhood selection.

  2. Trends:

    • Economic segregation may impact access to resources and opportunities, affecting overall community welfare.

  3. Impacts:

    • Economic segregation consequences include social isolation, access to education, and health disparities.

Summary of Findings

  • Neighbourhood effects significantly impact individuals' economic and social mobility, wellbeing, and overall life trajectories.

  • Both ethnic and economic segregation have profound implications on life outcomes, societal dynamics, and urban development.

Conclusion

  • Understanding neighbourhood effects is essential to address socioeconomic inequalities and promote integration in urban environments.

  • Effective policies need to balance the benefits of diversity with the potential drawbacks of segregation.
