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...

We study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources. The contribution of renewable and recyclable resources for sustainability is studied. Although in the short run recycling may alleviate resource scarcity,...

We study the optimal capacity and lifetime of landfills taking into account their sequential nature. Such an optimal capacity is characterized by the so-called Optimal Capacity Condition. Particular versions of this condition are obtained for two alternative settings: first, if all the landfills...

A theoretical model is presented in order to study the optimal combination of natural resources, used as inputs, taking into account their natural growth ability and the technical possibilities of input substitution. The model enables us to consider renewable resources, nonrenewable, or both....

We study under which conditions a learning by doing effect in the industry causes a monopolist to operate at a loss for some initial periods. Those conditions involve a parameter of the learning process, the slope of inverse demand function and the discount parameter. In order to get results, we...

Taking into account the great importance which the non-renewable energy resources have nowadays, and particularly the effects of their consumption on the environment and the problems associated with capturing rents, this paper analyses, through a two-period model, the interaction between...

The cost-effectiveness of support for renewable electricity is a main criterion to assess the success of policy instruments, together with effectiveness. The costs of support are also a source of significant concern for governments all over the world. However, significant confusion exists in the...

This paper presents a deterministic finite time horizon dynamic optimisation model aimed to determine optimal paths for artificial plantations and natural regeneration of two main tree species in dehesa multiple use ecosystems, holm oak (Quercus ilex L.) and cork oak (Q. suber L.). Whilst dehesa...

A nonlinear fractional programming problem is considered, where the functions involved are diferentiable with respect to an arc.Necessary and su±cient optimality conditions are obtained in terms of the right diferentials with respect to an arc of the functions. A dual is formulated and duality...
