This article explores the role of culture in encouraging the diffusion of cooperation for the production and marketing of agricultural products, an organizational innovation that can be related to technical progress in the rural sector and higher living standards for farmers. The results of the zero‐inflated negative binomial (ZINB) pooled regressions show that trust and religion were significant determinants of the diffusion of cooperatives among farmers in western countries. Results of the logit portion of these regressions suggest that the density of production was positively related to cooperation and that cooperation decreased where higher inequality in land distribution predominated.
