We are preparing an edited volume to be published in the Palgrave-International Political Economy series (series editor Timothy Shaw, University of Massachussets, Boston). This call is part of a multi-annual project that started with a workshop on migration and informality (March 27-28 2018, Lund University) and will continue with a conference possibly in summer 2019. With this book we are also gathering expressions for follow-up initiatives. If interested send an abstract by 30 June 2018 to Email: mobilities_informality2018@gmx.de Rationale Traditionally seen as " exporting " migrants to Western Europe and North America, the countries of Central and Eastern Europe, along with the former USSR ones, have recently become important mobility hubs. We start with an understanding of mobility that includes migratory processes to and from these countries. However, and this is the reason we prefer " mobility " to " migration " , we intend to take into account processes that go beyond migratory flows and include, inter alia, consequences of increased mobility for business activities (when mobility of capitals, people, services or items generates revenues, without necessarily resulting from temporary or permanent migrations), or seeking healthcare or other services in places other than your hometown. We believe that a large share of mobility-related activities generates informality, here defined as activities that happen outside the controlling, or coercing, presence of one or more states, or their institutions. There is a good body of literature dealing with migration, mostly from the region. This volume is, in our view, a way to complement existing literature in at least two ways. First, initial trends tended to see the region as strategic for outsourcing. However, the improvement of the economic conditions, along with the recent refugee crisis has added a second category of migrants to the region. This has meant that, in addition to the skilled workers, the region has also witnessed an increasing amount of immigration from people with either low qualifications, no legal right to work or stay or simply missing the skills to quickly integrate into local job markets. The issue of legality is only a marginal one. Indeed, the International Organisation for Migrations warns that only 10% of the migrants worldwide are formally illegal, leading us to think that the most important barriers to socioeconomic and legal integration are not formal but informal. In this respect, a number of studies have pinpointed at the contrast between the – de jure-existence of norms to deal with migrants against a de facto (partial or total) state incapacity to deal with migration flows and integration of foreign citizens in a number of cases.
