Causal Mechanisms, Job Search and the Labour Market Spatial Mismatch

Abstract

Many studies of the labour market spatial mismatch rely on the deductivenomological model of causation to test the theory that low-skilled, inner-city residents have been isolated from the knowledge of job opportunities by the suburbanization of jobs. The logic of this approach follows the deductivenomological model of explanation which establishes causation by measuring the constant conjunctions between ‘causes’ and ‘effects’. As an alternative, I have used a realist approach to the study of the labour market spatial mismatch that uses a ‘causal-explanatory’ method. This approach entails the qualitative description of the causal mechanism in order to discover and conceptualize its causal properties. The results suggest that the spatial mismatch theory could be refined in order to accommodate the finding that workers in excluded ghettos do not necessarily rely solely on local social networks to find out about job vacancies. Instead, workers with employment experience have strong workplace-based social networks. Since employers recruit workers by relying on referrals from trusted workers, these workplacebased social networks can put job seekers at the front of the hiring queue, regardless of where they live.
