A group-based approach to model behavior and institution co-evolution

Source-sink behavioural dynamics limit institutional evolution in a group-structured society (Hébert-Dufresne, Waring, et al 2022)

Control the axis of the phase diagrams (see below for parameter definition):

Things to try

Try maxing out behavioral transmission rate within group while reducing institutional cost. This is the only time it is worth investing in very strong institutions!

Analysis

Institutional localization: In some regime, we can see that some institutional levels dominate phase space. The faceted figure on the bottom corresponds to Figure 5 in the paper.
