We document that children growing up in places left behind by today's economy experience lower levels of social mobility as adults. Using a longitudinal database that tracks over 20,000 places in the USA from 1980 to 2018, we identify two kinds of left behind places: the 'long-term left behind' that have struggled over long periods of history; and 'recently left-behind' places where conditions have deteriorated. Compared to children of similar baseline household income levels, we find that exposure to left behind places is associated with a 4-percentile reduction in adult income rank. Children fare considerably better when exposed to places where conditions are improving. These outcomes vary across prominent social and spatial categories and are compounded when nearby places are also experiencing hardship. Based on these findings, we argue that left behind places are having 'scarring effects' on children that could manifest long into the future, exacerbating the intergenerational challenges faced by low-income households and communities. Improvements in local economic conditions and outmigration to more prosperous places are, therefore, unlikely to be full remedies for the problems created by left behind places.

The global financial crisis of just over a decade ago exposed longer-term systemic problems in global capitalism of which two of the most prominent are the slowdown in the underlying trend rate of productivity growth, alongside a rise in economic and spatial inequalities in many advanced economies. The Covid-19 pandemic looks set to further amplify these problems. This Editorial begins by discussing the scale of the productivity slowdown and of the widening inequalities that have emerged, particularly with regard to their spatial dimension: that is how the uneven and slow development of productivity and rise in inequalities have played out across and within regions and cities. It then briefly considers underlying factors that lie behind these trends, including financialisation / financial globalization, the diminishing role of organised labour, segmentation of the labour market favouring workers who play a key role in financialisation, together with the increasing polarisation within societies according to skill and, crucially, the impact of changing industrial composition particularly as it relates to the rise of the high-tech sectors. The Editorial then examines in what ways the slowdown of productivity and widening of economic and spatial inequalities, may be interrelated, and questions the notion of any efficiency-equity trade-off. Lastly, it considers whether the 'inclusive growth' agenda can potentially reconcile the two ambitions of improving productivity performance and lessening inequalities, reflecting on what inclusive growth could mean, and what it could imply in terms of policy. Thus far, it appears that an inclusive growth agenda has only gained some traction at the subnational level, which seems to reflect - at least in part - attempts by cities and regions to address gaps in policy left by national governments.
