This research evaluates the impact of collectively organized labor groups from a perspective of economic solidarity in cáritas sponsored projects on the welfare of indigenous peasant families in San Cristobal de Las Casas in Chiapas and Telixtlahuaca (Antequera) and Ixtepec (Tehuantepec) in Oaxaca. An evaluation model CIPP was used based on focus groups in the communities. The results have been analyzed and compared and showed evidences of how collective organized work offers alternative economic forms to neoliberal ones that could become viable proposals for policy making in rural development.
