The Trust Model focuses on inter-ethnic trust.
Inter-ethnic trust can fundamentally effect not only how communities function, but how they develop and interact with other local communities and ‘wider society’.
A better understanding of the ‘mechanics’ of inter-ethnic trust (and social trust in general) has the potential to reveal ways in which we can build and shape our communities to maximise the level of social trust.
Trust model v1.3.1
Behavioural experiments consistently show that rates of cooperation in Prisoner’s Dilemma Games (PDGs) are generally higher than would be expected based upon classical game-theoretic accounts, which assume actors behave to maximise only their own, immediate rewards (Camerer, 2003).
In this model we apply ‘other-regarding’ preferences (e.g. for ‘fairness’) to agents’ payoffs when playing PDGs, either in dyads or on a Von Neumann lattice.
The model specification mirrors aspects of a behavioural experiment conducted by Gracia-Lazaro et al. (2012), the results of which can be compared to the simulation.”
