This chapter sets out some conceptual points of departure for the book in terms of structural transformation and inclusive growth. It revisits the Lewis model of economic development and proposes it as a heuristic device to connect structural transformation and inclusive growth. The chapter argues first, that both structural transformation and inclusive growth have tended to be defined in a reductionist sense, in a way that disconnects the two concepts. It is contended that this matters because the relationship between structural transformation and inclusive growth is embedded in—rather than separated from—the modality of late capitalism pursued. Second, that the work of pioneering development economist, W. Arthur Lewis and the Lewis dual economy model provides a useful heuristic device for thinking about the relationship between structural transformation and inclusive growth.
