“…Markets are regarded as specific institutions or systems of rules that both constrain and enable agents’ choices, so that they should be investigated like any other institution; 2. the neoclassical concept of scarcity is substituted by a relative one, particularly institutions emerging from social interaction could produce stable institutional settings that are effective and not necessarily efficient (Ambrosino, , ); and 3. rational optimization can never supply a complete explanation of human behaviour and institutions (Vanberg, ), so that an interdisciplinary approach should be applied to understand the individual cognitive processes shaping agent's behaviour. To this end, CIE applies an interdisciplinary method based on empirical and experimental research (Ambrosino, , , ). Moreover, CIE argues that the analysis of the interdependent relationship between institutions and agents characterized by heterogeneity requires a cartographic approach (Mitchell, ) aimed at understanding and describing behaviour in specific contexts (NIE yet indicates the need for a comparative approach to investigate real arrangements).…”
