Content: For example, when disadvantaged groups perceive intergroup status relationships as illegitimate and unstable, collective action is predicted to occur, in an attempt to change status structures for the betterment of the disadvantaged group. Meta-analysis results also confirm that social identity causally predicts collective action across a number of diverse contexts. Additionally, the integrated SIMCA affords another important role to social identity – that of a psychological bridge forming the collective base from which both collective efficacy and group injustice may be conceived. Model refinement
While there is sound empirical support for the causal importance of SIMCA's key theoretical variables on collective action, more recent literature has addressed the issue of reverse causation, finding support for a related, yet distinct, encapsulation model of social identity in collective action (EMSICA). This model suggests that perceived group efficacy and perceived injustice provide the basis from which social identity emerges, highlighting an alternative causal pathway to collective action. Recent research has sought to integrate SIMCA with intergroup contact theory (see Cakal, Hewstone, Schwär, & Heath) and others have extended SIMCA through bridging morality research with the collective action literature (see van Zomeren, Postmes, & Spears for a review). Public good
The economic theory of collective action is concerned with the provision of public goods (and other collective consumption) through the collaboration of two or more individuals, and the impact of externalities on group behavior. It is more commonly referred to as Public Choice. Mancur Olson 's 1965 book The Logic of Collective Action: Public Goods and the Theory of Groups, is an important early analysis of the problems of public good cost.
