Fundamental institutional form
IEAs vary in their fundamental institutional form, Young classifies IEAs as regulatory, programmatic, procedural, or generative (Young, 1999b). Regulatory institutions proscribe or prescribe actions; procedural institutions establish procedures for regular collective decision making; programmatic institutions allow states to ‘pool resources’ for projects that would not be undertaken unilaterally; and generative institutions create new and ‘distinctive social practices’ (Young, 1999b: 28-31). These categories are ideal types, with some real-world institutions fitting neatly into these categories while others include element from each. Various aspects of problem structure (see chapter 2) make the choice of one or another of these alternatives more likely.
