We show that, even under incomplete markets, the equilibrium manifold identifies individual demands everywhere in their domains. Under partial observation of the manifold, we determine maximal subsets of the domains on which identification holds. For this, we assume conditions of smoothness, interiority and regularity. It is crucial that there be date-zero consumption. As a by-product, we develop a duality theory under incomplete markets.

En el presente artículo se aborda la naturaleza de los conflictos, sus principales componentes estructurales y su composición morfológica, desde el cambio de perspectiva (no lineal, ni determinista) propuesto por las teorías de la complejidad para las ciencias sociales. El análisis se centra en el estudio de los conflictos intratables, como fenómeno en el que interactúan de forma dinámica e interdependiente múltiples variables, creando un sistema complejo al que es necesario abordar como un todo y no por sus componentes particulares.El objetivo es estudiar la composición morfología que hace a este tipo de conflictos particularmente violentos, perdurables y resistentes a la trasformación pacífica. En función de esto, se expone la forma en que las estructuras psicosociales y la identidad grupal se convierten en los factores determinantes en la formación y composición que adquiere un conflicto intratable. Adicionalmente, se propone complejizar el entendimiento del tiempo como variables central de la intratabilidad, explicando las lógicas que permiten la estabilización de conflictos y el transito generacional por medio de las ideas de institucionalización de estructuras psicosociales y los atractores de conflicto.

Although anthropogenic impacts could be assessed in any environment, coastal areas pose a particular challenge because of their special nature as the interface between land and sea. Therefore, this study evaluates the environmental regulatory framework for coastal interventions in Colombia, as an archetype of medium income countries (MICs), to derive implications for the environmental licensing procedure (ELP). The methods comprised two simultaneous pathways: a. An inventory of human interventions at the large scale area of the Colombian Caribbean Coast, with an estimation of the overall environmental impact; b. An analysis of the ELP in Colombia during the last 25 years. The study evidences several weaknesses, such as a consistent reduction in the number of works and activities covered in each new legislative. Moreover, the Colombian ELP currently regulates only four of the ten types of interventions with greater effect in its coastal zones. The discussions highlight some policy implications for the ELP in MICs, mainly based on how the impact of a type of intervention can be magnified in proportion to its frequency of occurrence, and the need to articulate instruments of environmental management and territorial planning. At last, the need to evolve the impact assessment of human interventions from environmental factors toward socio-natural processes is evidenced and further addressed, by the introduction of a susceptibility approach inspired on geomorphological processes. Overall, this study highlights important gaps of the Colombian ELP for coastal environments, which entails valuable lessons for MICs.
