The role of informal institutions in the use of forest resources in Latin America por Pacheco, P., Barry, D.M., Cronkleton, P., Larson, A.M.

“…The principal findings suggest that in spite of the fact that many governments have introduced progressive policies intended to benefit rural populations and their forest use, it is questionable the extent to which such policies have actually brought about any real change to benefit communities. Exploring the role of informal institutions, as they interact with formal law, is important to explain these outcomes in practice. …”
