“Superficial Water Concessions In Light Of The General Theory of the Administrative Act” The Incidence of the Public Law’s Dogmatic Tradition of Public Law Within Environmental Law

This paper seeks the determine the ways in which anomalous decisions derived from the particularization and constitutionalization of environmental law can arise given the general theory of administrative action. This is seen through the lens of a study and characterization of administrative decisions issued by the Regional Autonomous Corporation of Cundinamarca –CAR- within the superficial water concessions procedure. It also discusses the conceptual contents of these licenses.

Análisis de la implantación de centros comerciales y su relación con el desarrollo urbano a escala zonal en Bogotá: el caso del centro comercial Centro Mayor (2008-2013)

El interés de esta investigación es el de analizar las relaciones que se dan entre un centro comercial y el barrio en el que se implanta, con un énfasis socioeconómico, en Bogotá. Se explica el fenómeno de expansión de centros comerciales en la ciudad, la importancia estratégica del caso de estudio, ubicado en el sur de Bogotá y las transformaciones causadas por su implantación, en un contexto particular marcado por lo que significa el sur de Bogotá. El estudio encuentra que a través de un centro comercial de gran dimensión, como lo es Centro Mayor, han cambiado las relaciones del barrio con sus vecinos, así como sus actividades cotidianas, su relación con la ciudad y con los límites que alguna vez se había impuesto al barrio. Lo anterior, en medio de una constante reflexión sobre el papel de los centros comerciales en las ciudades y el debate que debe haber sobre el modelo que se implanta con un expansión.

Why labor income shares seem to be constant?

The common assumptions that labor income share does not change over time or across countries and that factor income shares are equal to the elasticity of output with respect to factors have had important implications for economic theory. However, there are various theoretical reasons why the elasticity of output with respect to reproducible factors should be correlated with the stage of development. In particular, the behavior of international trade and capital flows and the existence of factor saving innovations imply such a correlation. If this correlation exists and if factor income shares are equal to the elasticity of output with respect to factors then the labor income share must be negatively correlated with the stage of development. We propose an explanation for why labor income share has no correlation with income per capita: the existence of a labor intensive sector which produces non tradable goods.

If factor shares are not constant then we have a measurment problem. can we solve it?

Recent evidence show that factor shares, if properly measured, are far from constant. Moreover, the shares of natural resources and raw labor seem to be negatively correlated with income per capita while the share of human and physical capital is positively correlated with income per capita. Now, if factor shares are not constant then (i) growth accounting exercises rely on a false assumption and (ii) there is a measurement problem. The effect that change s in factor shares ha ve on output depend on the relative abundance of factors and, fo r this reason, it is necessary to have correct measures. We propose an empiri cal methodology to solve the measurement issue and estimate TFP growth.
