Overview of the Special Issue

The aim of this Special Issue is to describe and analyse the responses of residence-based social security schemes in relation to free movement as it is formulated in EU Law. The articles contain accounts on how legislative changes in residence-based schemes have been made in various EU Member states and reflections on how these changes have led to changes in the values underpinning social security systems in these countries. This introduction address the issues on how free movement creates pressure on national law, and gives an overview of the content and aims of the Special Issue.
