Changes in statistics for a toy model, in responseto policy changes. Changes in C (dark line) and S (light line) for a focal player with a single state (x = 1) in response to changes in the likelihood of a co-player performing the target behaviour b₁ if is in the first of two possible states (y = 1), for the simple toy model described in the text. The graphs show changes in response to differing values of b₂ (the likelihood the co-player conducts the target behaviour when it is in its second state). In all graphs d₁₁ = 0.5 and d₁₂ = 0.5.
