Migration Law

Population movements modify the environment, land-use, and shape the landscape through urbanization. Furthermore, migration has become one of the most relevant determinants of global human health and social development. The objective of this paper is to provide a framework to understand the economic and natural factors responsible for migration and population agglomerations and their environmental consequences. In this regard, we develop an economic model in continuous time and space adapting Hotelling’s migration law to make individuals react to possible improvements of their welfare. First we show that there is solution to this spatial-dynamic problem. Then, we illustrate the properties of the economy and the associated population dynamics through numerical simulations.

Migration Law

Part I of this symposium on framing global migration law introduced broad conceptual parameters of a new field, looking back to its international law roots and forward to a new orientation beyond the strictures of refugee law. Part II looks to situate global migration law along a range of theoretical dimensions. Jacqueline Bhabha establishes the continuities of human movement in a historical context, modern and premodern. Far from representing a radical departure, the current migration “crisis” is consistent with massive migrations over the ages. Tendayi Achiume considers migration through the lens of colonization and decolonization. Out-migration from Europe was a core economic element of the colonization project; Achiume suggests that contemporary migration from former dependencies to metropolitan powers will correct co-dependencies that continue to advantage postcolonial powers. Focusing Achiume's lens on the problem of human trafficking, Janie Chuang complicates the binary depictions of economic migration that underpin contemporary international law. She suggests that global migration law's grounding in a migrant-centered perspective could help state actors to understand the structural causes of modern-day exploitation, enabling a shift from a crime control approach to a human mobility paradigm.
