Conceptualising Social Housing within the Wider Housing Market: A Vacancy Chain Model

There have been increasing calls for studies of housing systems that are more integrative and pluralistic in nature. Understanding the relationship of social housing systems to the wider housing market remains a key challenge. The mobility of households and the structural configuration of supply are both of importance, demanding methods able to reconcile both. This paper propounds vacancy chain models as offering significant potential in this regard, allowing policy analysis and options appraisal to be built on more dynamic conceptualisations of housing systems. The theoretical basis for vacancy chain models is developed before an account is given of a model developed of the Bradford (UK) social rented sector. The results suggest that social renting is very closely linked to the wider housing market and consequently the impacts of policy and investment may be felt beyond the sector. Observations on the future development of vacancy chain models are offered.
