“…On the one hand, centralisation allows more specialisation, and hence gains from the division of labour, whilst on the other hand, the problems of communication and control increase more than proportionately with the size of the organisational unit (Arrow, 1974). Generally speaking, the larger the information content of policy implementationfor example, about local needs and circumstancesthe greater will be the case for decentralisation, often to levels below those of national governments (Helm and Smith, 1987). However, in the cases where there are substantial unexploited economies of scale in implementation at the level of national governments, this could constitute a reason for assignment to the EC level, which would outweigh the disadvantages of insensitivity to local or national preferences and objectives.…”
