(a) Associations of each predictor term (fixed effect) with proposer offers in the null (intercept only) and full models. (b) Village- and individual-level variance components for proposer offer in the null and full models.a (The variance partition coefficient (VPC = village-level variance/(village-level variance + individual-level variance)) is 0.144±0.054 (95% BCIb = 0.063, 0.273) in the null model, and 0.112±0.049 (95% BCIb = 0.040, 0.228) in the full model. ***p < 0.01; **p < 0.05; *p < 0.10.)

aFor the two multilevel models (null and full), fixed-effect parameters in each model are specified in table 2a, while table 2b presents the village- and individual-level variances in proposer offers for each model, respectively. For instance, in table 2a, the full model (multilevel) has four fixed effects including the intercept; for each fixed effect (column 1), the associated β-value (column 2) and its 95% BCIb (column 3) can be read in the corresponding row. The DICc value for the model is presented in column 4 of table 2a. The variance components for the full model (multilevel) can be read in the last row of table 2b; column 2 represents the village-level variance in proposer offers with its 95% BCIb (column 3), and column 4 represents the individual-level variance in proposer offers with its 95% BCIb (column 5). The fixed effect parameters for the single-level null model are presented in table 2a; this model does not have variance components.
