The Institutional Analysis and Development framework (IAD) was developed by Elinor Ostrom, an American political scientist, also known as the first woman to receive the Nobel Memorial Prize in Economic Sciences in 2009. The IAD relates a set of concepts to help in the analysis of collective action problems that involve social structures, positions, and rules. Under the rational choice models, the IAD was devised in an attempt to explain and predict outcomes by formalising the structures, positions, and rules involved in collective choice problems. Thus, it can be seen as a systematic method to collect policy analysis functions similar to analytic technique commonly used in physical and social sciences and understand how institution 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 regularised interactions in an established 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).
|Position||The number of possible "positions" actors in the action situation can assume (in terms of formal positions these might be better described as job roles, while for informal positions these might rather be social roles of some capacity|
|Boundary||Characteristics participants must have in order to be able to access a particular position|
|Choice||The action capacity ascribed to a particular position|
|Aggregation||Any rules relating to how interactions between participants within the action situation accumulate to final outcomes (voting schemes etc.)|
|Information||The types and kinds of information and information channels available to participants in their respective positions|
|Pay-off||The likely rewards or punishments for participating in the action situation|
|Scope||Any criteria or requirements that exist for the final outcomes from the action situation|
