Concept and origins
Kain (1968) argued that as factories and jobs moved to suburbs, Black residents constrained by housing discrimination remained in central cities, far from work, raising unemployment. Residential segregation itself can be modelled with Schelling's segregation model. Wilson (1996) analysed jobless inner-city neighbourhoods, connecting the debate to the underclass.
Mechanisms
Gobillon, Selod and Zenou (2007) outlined several channels: long commutes are costly, poor public transport makes them impractical, information about distant jobs is scarce, and suburban employers may discriminate. Inner-city workers are then pushed toward low-wage jobs in the secondary labour market.
Evidence and policy
Holzer (1991) found broad support for the hypothesis, and Kain (1992) reviewed three decades of debate. Ihlanfeldt and Sjoquist (1998) drew lessons for welfare reform, such as transport support and job linkage. Hellerstein, Neumark and McInerney (2008) suggested racial mismatch in hiring may matter more than distance. The hypothesis highlights the spatial side of social exclusion.
FAQ
- What is spatial mismatch in simple terms?
- Jobs are far from where workers live, so finding and keeping work becomes harder.
- What policies are proposed?
- Better transit and commuting support, job information links and help to move.
