El proyecto investigativo Ecoacam Zice, liderado por la Universidad Técnica del Norte (del Ecuador) y la Universidad Mariana (de Pasto, Colombia) busca analizar la cultura organizacional y los medios de vida de las asociaciones campesinas que integran el cordón fronterizo colombo-ecuatoriano. Este proyecto ha hecho posible obtener información sobre el impacto económico actual en las agrupaciones agrarias ubicadas en la zona limítrofe de los dos países. La información muestra el restringido acceso a los emprendimientos, la escasa participación conjunta en proyectos y los esfuerzos constantes que los campesinos deben hacer para la obtención de ingreso para sus hogares, así como el conjunto de necesidades que aún están insatisfechas. Dicha iniciativa busca promover políticas públicas y acciones enfocadas al fortalecimiento organizacional en los sector...

Different analyses are carried out based on the Spanish Survey on Income and Living Conditions (ECV) that continued to ask households for their income despite assigning their income data as provided by the Tax Agency and the Social Security Administration. Our main finding is that the largest discrepancies between administrative and survey data are in the tails of the distribution. In addition to that, there are clear differences in the level and structure of inequality across data sources. These differences matter, and our results should be a wake-up call to interpret the results based on only one source of income data with caution.

Most available evidence considers performance indicators that are too general, there being few studies relating the use of inputs to outcomes.
