Table 4. Decomposition of effect of self-excluded model (3a) and its re-parameterized form (3b).

Model a	All effect	Decomposition of all effect
Original model (model 3a)
	α 1+γ 3	Self effect: α 1
		Others effect: γ 3
Re-parameterized model (model 3b)
	α 1+γ 3	Individual-like effect:
		Compositional-like effect:

^aAs explained in the main text, y_ij is an observed outcome of individual i in group j, x_ij is an individual-level social capital score of individual i in group j,  =  is the mean of social capital scores of all individuals in group j, n_j is the size of the group j, and  =  is the mean of social capital scores of all individuals (excluding individual i) in group j.
