Abstract
This chapter focuses on how the concepts of marginality and marginalisation compare and contrast with the key components of the core-periphery model and the associated notion of peripheralisation. We discuss the genesis of the core-periphery model, its key elements, and how it can be strengthened by drawing on the economic and sociological insights of marginality thinking and the more recent conceptual lens of ‘left-behindness’. Marginal areas/places/regions or ‘margins’ are often considered as equal to left behind places, backward or remote places, as well as the notion of the periphery. However, a marginal area or margin does not always correspond to a periphery as outlined in the concept of the core-periphery continuum (CP). The chapter starts with an examination of the core-periphery model. We then move on to examine, in sequence, economic and then sociological perspectives of what marginality is, and finally, we explore how new concepts such as ‘left behind places’ can extend and enrich the debate.
