In focusing on markets and commerce, this chapter discusses the complex cross-border institutions designed to encourage crossborder economic activity, and the cross-border flows of economic actors in their roles as tourists, commuters and students. It is concerned with the impact of devolution on everyday life through the prism of cross-border commerce. The story of cross-border economic cooperation is linked to the creation of North-South implementation bodies in 1999 under Strand Two of the Good Friday Agreement. The chapter shows how cross-border linkages and flows, with a consequent impact on everyday experience, have increased since 1999. One area where there is a strong impression of a cross-border market or commercial life working to its optimal level is that of shopping. Crossborder shopping is an issue that periodically (and temporarily) becomes a favourite topic for media interest and political oratory.
