The main goals of the current volume are to:

1. Provide further empirical evidence on the existence, performance and persistence of mobility-related informal practices. In particular, we are interested in what informal practices are boosted by the new opportunities provided by increased mobility at a country, region and global level

2. Explore the relationship between mobility patterns and informal practices to consolidate a sub-field of informality studies and contribute to a broader understanding of informal practices in Eastern Europe and the former USSR
