From: Why do inequality and deprivation produce high crime and low trust?
Optimal actions as a function of the individual’s current resources s and the trustworthiness of the surrounding population, 1 − p. (A) All parameters at their default values. This includes: α = 1.2, r = 0.1, π = 10, and γ = 1/3 (see Table 1 for a full list). (B) Effect of altering the efficiency of cooperation α to be either lower (1.05) or higher (1.30) than (A). Other parameter values are as for (A). (C) Effects of varying social mobility, to be either high (r = 0.8), or complete (r = 1.0; i.e. resource levels in this time period have no continuity at all into the next). Other parameter values are as for (A). (D) Effect of increasing the severity of punishment for exploiters to π = 15 and π = 20. Other parameter values are as for (A). (E). Effects of altering the probability of punishment for exploiters to γ = 2/3 and γ = 9/10. Other parameter values are as for (A).
