Demand and supply analysis in fisheries often indicates the presence of instabilities and multiple equilibria, both in open access conditions and in the socially optimal solution. The associated management problems are further intensified by uncertainty on the evolution of the resource stock or...

Efficiency has long been an issue of concern in the electricity sector. Most existing studies relate technical efficiency in the electricity sector to policy or environmental factors. The impact of firm operation factors has rarely been discussed. We estimate Stochastic Frontier models using...

Economic literature on groundwater managementhas traditionally been split into two areas: there are papers that evaluate different schemes of dynamicaquifer management, considering that pumping costs vary with stock but ignoring water quality. On the other hand, there are papers that...

The tariffs applied in the Portuguese water industry are very complex, making their analysis difficult and hampering the objective of efficiency, acknowledged as an important tool in water management by Portuguese and European legislation. In this article we present the main criteria to be taken...

Across Europe, CO2 emission permits represent one of the main policy instruments to comply with the limits established by the European Commission to achieve the goals of the Kyoto Protocol. In this paper we use microdata to address two issues regarding the impact of the European Carbon Market...

Models of economic growth are typically based on the use of one or more stocks of productive assets to create goods for utility-generating consumption. The roles played by man-made capital, natural capital, and human capital have been explored in the literature, and more recently the notion of...

Since surface water flows are often stochastic, there is a role for water reservoirs in protecting users against uncertainty. We assume uncertainty regarding the probability distribution for the stochastic variable. Thus the decision allows for a range of approximate models that could be true,...

In many areas where water is not abundant, water pricing schedules contain significant nonlinearities. Existing pricing literature establishes that efficient schedules will depend on demand and supply characteristics. However, most empirical studies show that actual pricing schemes have little...
