Abstract: | En este trabajo se presenta un análisis de la gestión de residuos sólidos urbanos desde una perspectiva económica. Se profundiza en los fallos de mercado que produce la generación y la gestión de los residuos y se discuten los principales instrumentos de política que se pueden utilizar para corregir dichos fallos. En particular, se presta especial atención a las políticas de incentivos y se clasifican y se enumeran las principales ventajas e inconvenientes de cada una de ellas. También se realiza un breve recorrido sobre los acontecimientos recientes y los cambios en los principios y las prácticas de gestión en el ámbito nacional e internacional. |
Keywords: | Residuos sólidos urbanos, fallos de mercado, políticas de incentivos, vertido, reciclaje. |

Abstract: | Conflicts between optimality and sustainability are typical in the literature on sustainable development. Using the 'capital-resource' growth model, Pezzey and Withagen (1998) have proved that if natural resources are exhaustible, the time-path of consumption is single-peaked, declining from some point in time onwards. This paper extends the model to include technical progress, resource renewability, extraction costs and population growth. The main result is that, for any constant returns to scale technology, optimal paths can be sustainable only if the social discount rate does not exceed the sum of the rates of resource regeneration and augmentation. The development of resource-saving techniques is crucial for sustaining consumption per capita in the long run, whereas capital depreciation and extraction costs are neutral with respect to this sustainability condition. |

Abstract: | A global multi-sectoral, multi-regional computational general equilibrium model is employed to assess carbon taxes under perfect competition and monopoly. We found that regional studies of carbon taxation maybe inaccurate due to the carbon emission spillover effects. Emission taxes have stronger impacts on the economy in monopoly rather than on perfect competition in terms of magnitude. Carbon emission tax policy analysis which is based on perfect competition may also underestimate the losses of welfare compared with the case in imperfect competition. |

Abstract: | La production de services semble en phase avec les dynamiques rurales (croissance des attentes de protection de l'environnement et des usages récréatifs et résidentiels, tourisme rural…). L'objectif de cette communication consiste à relire les services fournis par l'agriculture, avec un cadre de lecture économique de la production de services. Sur le plan empirique, nous mettons l'accent sur les conditions de développement de l'agriculture de service et plus particulièrement sur les services environnementaux. |

Abstract: | Traditional resource economics has been criticised for assuming too high elasticities of substitution, not observing material balance principles and relying too much on planner solutions to obtain long-term growth. By analysing a multi-sector R&Dbased endogenous growth model with exhaustible natural resources, labour, and knowledge capital as inputs, the present paper addresses this critique. We study transitional dynamics and the long-term growth path and identify conditions under which firms keep spending on research and development so that growth is sustained. We demonstrate that long-run growth can be sustained under free market conditions even when elasticities of substitution between man-made inputs and resources are low. |

Abstract: | The paper aims to substantiate the importance of endogenous innovations when evaluating the compatibility of natural resource use and economic development. It explains that technological change has the potential to compensate for natural resource scarcity, diminishing returns to capital, poor input substitution, and material balance restrictions, but is limited by various restrictions like fading returns to innovative investments and rising research costs. It also shows how innovative activities are fostered by accurate price signals and research-favouring sectoral change. The simultaneous effects of increasing technical knowledge, decreasing resource inputs, and increasing world population largely determine the chances of long-run sustainable development. Consequently, future research has to be directed at a more thorough understanding of the mechanisms driving innovations in the presence of natural resource scarcity. |

Abstract: | Using a dynamic model with non-renewable natural resources and endogenous knowledge creation, the paper analyses economic development under conditions which are generally considered as most unfavourable. We assume poor substitution between primary input factors, positive population growth and a limited supply of materials in the static part of the framework, as well as natural resources being an essential input into R&D, and constant or decreasing returns to innovative activities in the dynamic part. It is shown that there is an inverse relationship between input substitution and growth-enhancing sectoral change and that labour supply supports economic dynamics through the knowledge-creation effect. A permanent increase in living standards is achievable under free market conditions, but adjustment costs and errors in long-term expectations might impede this development. |

Abstract: | In recent years, extensive literature on the Environmental Kuznets Curve lead- ing to optimistic policy conclusions has attracted great attention. However, the underlying cross-section estimations are not very reliable. Accordingly, this contribution uses time series data for a single country with dependable data quality : Germany. The results of the traditional reduced-form specification do not support the EKC hypothesis. However, with a specification in the tradi- tion of error correction models, which are more appropriate in the presence of non-stationary time series, it is found that the typical EKC pattern can be confirmed. |
