'Jonas Tallberg and his co-authors have collected a uniquely refined dataset of transnational access to almost 300 international bodies over time, which forms the backbone for the first systematic explanation of transnational design. This path-breaking study will change our understanding of global governance.' Liesbet Hooghe, University of North Carolina, Chapel Hill and VU University, Amsterdam
