Table 1.
Treatments and sample sizes in the 2 x 2 design of the CPR experiment.
On one dimension, village (CH: Chwaka, MA: Marumbi) is varied by recruiting subjects from two different locations, on the other dimension, sociocultural group heterogeneity is varied by placing subjects either in homogeneous (single-village) or heterogeneous (mixed-village) groups.

(A) Mean extraction decisions of fishers under sociocultural homogeneity (groups of fishers from only the own village) and heterogeneity (groups of fishers from own and other village) over time. (B) Mean extraction decisions of fishers from Chwaka village (CH) and Marumbi village (MA) under sociocultural homogeneity and heterogeneity over time.
