ABSTRACT
This introduction argues for a new research agenda on European internal security cooperation from the perspective of public goods. We set out our case in three parts. First, we identify new empirical puzzles and demonstrate significant explanatory gaps in the existing internal security literature which public goods theory could help address. Second, we outline the building blocks of a public goods approach and provide an overview of its application, both existing and potentially, in various areas of regional security and European integration. Third, we present three complementary ways of using public goods theory to analyse internal security in the European Union, with the aim of spurring new research questions while accepting some limitations of this theoretical approach.
