The Ashgate Research Companion to Migration Law, Theory and Policy complements the already successful Ashgate series Law & Migration, established in 2006 which now has a number of well-regarded monographs to its credit. The purpose of this Companion is to augment that Series, by taking stock of the current state of literature on migration law, theory and policy, and to sketch out the contours of its future long-term development, in what is now a vastly expanded research agenda. The Companion provides readers with a definitive and dependable state-of-art review of current research in each of the chosen areas that is all-embracing and all-inclusive of its subject-matter. The chapters focus on the regional and the sub-regional, as well as the national and the global. In so doing, they aim to give a snap-shot that is contextual, coherent, and comprehensive. The contributors are both world-renowned scholars and newer voices and include scholars, practitioners, former judges and researchers and policy-makers who are currently working for international organisations.

ERRATUM The sentence on p. 153, lines 5-7 should read "...if welfare expenditure had not risen but remained at its 1987 level, the rise in imprisonment would have been 20 per cent greater than actually occurred, i.e. from 75 in 1987 to 99 in 1998." No other part of the book is affected by this correction.
