The Impact of Regulation on Pricing Behavior in the Spanish Electricity Market

In this paper we measure the impact of regulatory measures which affected the Spanish electricity wholesale market in the period 2002-2005. Our approach is based on the fact that regulation changes firms' incentives and therefore their market behavior. In the absence of any regulation firms would choose profit- maximizing prices on their residual demands so that the observed gap between optimal and actual prices provides a measure of the effect of regulation. Our results indicate that regulation has decreased wholesale prices considerably, but became less effective at the end of the sample period which explains the change of regulatory regime introduced in 2006.

Is the Current Regulation of the VIII Division European Anchovy Optimal?

This paper sets out to assess the workability of the regulation currently in force in the European anchovy fishery of the VIII division. Particular attention is paid to the importance of the institutional regime in the allocation of natural resources. The study uses a bio-economic approach and takes into account the fact that, not only the European Union and the individual countries involved, but also some of the resource users or appropriators intervene in its management. In order to compare the effectiveness of the rules which, at the various levels, have been set up to restrict exploitation of the resource, the anchovy fishery is simulated in two extreme situations: open access and sole ownership. The results obtained by effective management will then be contrasted with those obtained from the maximum and zero profit objectives related with the two above-mentioned scenarios. Thus, if the real data come close to those derived from the sole ownership model it will have to be acknowledged that the rules at present in force are optimal. If, on the other hand, the situation more closely approach the results obtained from the open access model, we will endeavour in our conclusions to provide suggestions for economic policy measures that might improve the situation in the fishery.

Depuración de aguas residuales urbanas y concentración de metales en fangos digeridos

[ES] La progresiva implantación de plantas de tratamiento de aguas residuales urbanas ha ido estableciendo una experiencia en el conocimiento de la eficacia de tratamiento de los diversos parámetros en plazos largos de funcionamiento. El análisis y comparación de resultados y tecnologías debe pennitir conocer las características de fiabilidad en la operación y el comportamiento frente a los diversos aspectos de la nonnativa legal. Además, el análisis en diferentes épocas del año puede producir distintos resultados o conclusiones. En este trabajo se ha tomado para el análisis una planta de tratamiento convencional, estudiando inicialmente los porcentajes medios de eliminación de diferentes parámetros, en relación asimismo con las necesidades que debe satisfacer. En condiciones de alta carga orgánica, la concentración de nitrógeno y algún tóxico especial parecen plantear las mayores dificultades. Se ha deseado focalizar la atención en el proceso de concentración de metales que se. produce en las plantas con tratamiento anaerobío de fangos. Por este motivo se Uevó a cabo un estudio de la evolución de metales en la depuración y la concentración de fangos digeridos. El fenómeno resulta de interés para analizar la calidad de las aguas que se obtienen, aunque debe considerarse también la concentración de metales en el destino final que se dé a los fangos tratados.
