While migration scholars often neglect the national and transnational relations of production and exchange within which labor migration occurs, international political economists tend to treat labor migration as a mere side effect of transnational capitalism. By contrast, this article considers the constitutive role that post-socialist transformations and the EU integration played in shaping the various patterns of intra-European east-west labor migration since 1989. We argue that labor migration was not driven by development differentials between the west and the east as such, but rather by the particular type of development the latter adopted after the fall of communist regimes and by the way post-socialist countries were integrated in transnational circuits of production and exchange. We are sustaining our claims by a comparative assessment across time of the articulations between the different modes of production and different labor migration patterns during different stages of Romania's post-socialist transformation. This historical comparison enables us to insulate the influence of changing levels of development and modes of production on labor migration because our focus on a single country is keeping the influence of other national institutional factors constant. © 2014 © 2013 Taylor & Francis.
