• Source: Institutional analysis and development framework

      • The Institutional Analysis and Development framework (IAD) is a theoretical framework for investigating how people ("actors") interact with common-pool resources (CPRs). CPRs are economic goods which are rivalrous (i.e. one person's use reduces the ability of others to use) and non-excludable (i.e. it's impractical to prevent people accessing it) - examples include forests as a source of timber, or fields as a source of pasture.
      It was developed by Elinor Ostrom, an American political scientist and the first woman to receive the Nobel Memorial Prize in Economic Sciences in 2009. Ostrom researched which institutional structures supported CPR actors to sustainably use their resources, balancing individuals' use with the interest of a wider public. Under rational choice assumptions, the IAD was devised in an attempt to explain and predict outcomes by formally exploring and documenting governance structures, actors' positions, and informal and formal rules. Thus, the IAD is a systematic method to document policy analysis functions similar to analytic technique commonly used in physical and social sciences to understand how institutions operate and change over a period of time.


      Components of the framework



      Ostrom thought of the IAD as a "multi-level conceptual map" with which one could zoom in and out of particular hierarchical parts of the governance structures in a social system.
      The IAD framework helps to perceive complex collective action problems by dividing them into 'action arenas', that are smaller pieces of practically understandable function. The analyst assumes that the structure of the action situation is fixed in the short-term. For an action situation to exist, there must be "actors in positions" (the number of possible roles that are available in this recurring interaction situation). Actors have choices within the existing (rule) structure. In the study of outcomes from collective choice situations, actors are influenced by the institutional arrangements, the socio-economic conditions, and the physical environment. The institutional arrangements can be studied by seven rule types (as per below).
