By explicitly considering the spatial dimension of local regional labor markets, we develop a simple dynamic model that explains the spatial correlation between unemployment rates. We then test this model by using UK local data. Our evidence shows a significant spatial dependence that has been growing over time and characterized by a low distance decay. Highly localized effects are explained by commuting flows. These results are consistent with the theoretical model. Copyright 2007, Oxford University Press.
