Infraestructuras verdes : análisis de la práctica de los anillos verdes

En los últimos años, alcanzar la Economía Verde parece ser la aspiración perseguida por la sociedad, dado que representa un paso decisivo para lograr el Desarrollo Sostenible y con ello una ciudad sostenible. Sin embargo, las ciudades de todo el mundo han experimentado cambios en su fisonomía debido a los continuos procesos de urbanización que han fomentado un crecimiento desmedido de las mismas, además de generar una serie de efectos negativos que las alejan del camino hacia la sostenibilidad. De tal manera, que a medida que dicho crecimiento aumenta, cada vez son menores las áreas verdes localizadas en las periferias de las ciudades. Para responder a estos problemas asociados al crecimiento urbano y, por ende, al consumo de tierra, se han diseñado diversos instrumentos entre los que destaca la práctica de los Anillos Verdes, siendo el estudio de dicha práctica el objetivo de este trabajo. Con el fin de tener una amplia visión de la implementación de la práctica de los Anillos Verdes, en primer lugar, se describen de manera general algunos casos a nivel internacional, para, a continuación, profundizar en algunas de las principales prácticas europeas y españolas, confirmando, de este modo, que representan una práctica muy extendida en Europa, mientras que en España todavía se encuentran en un estado emergente.

Mas-Colell, Whinston and Green Versus Scitovsky on Profit and Utility Maximization

I contrast the theoretical foundation of profit maximization of Mas-Colell, Whinston and Green’s “Microeconomics” against that provided by Scitovsky in a paper of 1943. Whereas Mas-Colell, Whinston and Green try to show that profit maximization can be derived from utility maximization, Scitovsky categorically states the contrary view. I argue, first, that the foundation provided by Mas-Colell, Whinston and Green is not sound and, secondly, that Scitovsky’s line of reasoning opens a better way to model business behavior.

Second-best tax policy in a growing economy with externalities

This paper investigates the exploitation of environmental resources in a growing economy within a second-best scal policy framework. Agents derive utility from two types of consumption goods one which relies on an environmental input and one which does not as well as from leisure and from environmental amenity values. Property rights for the environmental resource are potentially incomplete. We connect second best policy to essential components of utility by considering the elasticity of substitution among each of the four utility arguments. The results illustrate potentially important relationships between environmental amentity values and leisure. When amenity values are complementary with leisure, for instance when environmental amenities are used for recreation, taxes on extractive goods generally increase over time. On the other hand, optimal taxes on extractive goods generally decrease over time when leisure and environmental amenity values are substitutes. Unders some parameterizations, complex dynamics leading to nonmonotonic time paths for the state variables can emerge.

Optimal Minimum Wage in a Competitive Economy: an Alternative Modelling Approach

This paper analyzes whether a minimum wage can be an optimal redistribution policy when distorting taxes and lump-sum transfers are also available in a competitive economy. We build a static general equilibrium model with a Ramsey planner making decisions on taxes, transfers, and minimum wage levels. Workers are assumed to differ only in their productivity. We find that optimal redistribution may imply the use of a minimum wage. The key factor driving our results is the reaction of the demand for low skilled labor to the minimum wage law. Hence, an optimal minimum wage appears to be most likely when low skilled households are scarce, the complementarity between the two types of workers is large or the difference in productivity is small. The main contribution of the paper is a modelling approach that allows us to adopt analysis and solution techniques widely used in recent public finance research. Moreover, this modelling strategy is flexible enough to allow for potential extensions to include dynamics into the model.

The position of a social economy in the Czech Republic at present

The Social Economy is a new phenomenon in the Czech Republic. It means the economy with its social effects that is being supported within public politics. Some analyses have been done at J.E:purkynI University in Ústí nad Labem during the last years. The topics of this research were the transformation of public administration, non-profit sector(respectively the civil mix sector), co-operatives, and social enterprises, and it is still ongoing.

Income Taxation and Growth in an OLG Economy: Does Aggregate Uncertainty Play any Role?

We analyze the effects of capital income taxation on long-run growth in a stochastic, two-period overlapping generations economy. Endogenous growth is driven by a positive externality of physical capital in the production sector that makes firms exhibit an aggregate technology in equilibrium. We distinguish between capital income and labor income, and between attitudes towards risk and intertemporal substitution of consumption. We show necessary and sufficient conditions such that i) increments in the capital income taxation lead to higher equilibrium growth rates, and ii) the effect of changes in the capital income tax rate on the equilibrium growth may be of opposite signs in stochastic and in deterministic economies. Such a sign reversal is shown to be more likely depending on i) how the intertemporal elasticity of substitution compares to one, and ii) the size of second- period labor supply. Numerical simulations show that for reasonable values of the intertemporal elasticity of substitution, a sign reversal shows up only for implausibly high values of the second- period’s labor supply. The conclusion is that deterministic OLG economies are a good approximation of the effect of taxes on the equilibrium growth rate as in Smith (1996).
