Génesis y desarrollo de las asociaciones agrícolas y de propietarios territoriales en España

Since relatively a few years ago research work regarding the genesis and evolution of agrarian organizations in our country has been carried out. Studies with a marked regional emphasis that, rarely were able to reference the true state of the associational framework during the nineteenth century, exception made of the Sociedades Económicas and of very concrete monographic studies. It is necessary to go back to the first years of the past century to find the first descriptions and working papers alluding the agrarian associational framework in Spain. On this respect, José Elías de Molins already did a study entitled La Asociación y Cooperación Agrícolas, published in the year of 1912, in which a recount of confraternities and brotherhoods verified by the Consejo de Castilla in 1770 was done. The first of modern references related to the agrarian organizations, properly speaking, corresponds to Juan Pan-Montojo in his well known work “La naissance des associations agraries en Espagne 1833-1898”, in which the consequences and changes effected in economic power structures were reflected, once the suppression of privileges linked to the land had started, as a consequence of the strengthening of liberalism in a large portion of the state’s farms. After him, came he important works of, among others, Jordi Planas and Germán Rueda. On a comparative level, the formation of agrarian societies with mobilization capacity in other European states certainly took the same amount of time to happen. Thus, the Société des Agriculteurs de France or the Société Nationale et Centrale d’Agriculture, in 1867 and 1871, respectively, came to remind the Sociedades Económicas de Amigos del País in Spain...

A bidding strategy for minimizing the imbalances costs for renewable generators in Spanish power markets

The aim of this paper is to suggest a simple methodology to be used by renewable power generators to bid in Spanish markets in order to minimize the cost of their imbalances. As it is known, the optimal bid depends on the probability distribution function of the energy to produce, of the probability distribution function of the future system imbalance and of its expected cost. We assume simple methods for estimating any of these parameters and, using actual data of 2014, we test the potential economic benefit for a wind generator from using our optimal bid instead of just the expected power generation. We find evidence that Spanish wind generators savings would be from 7% to 26%.
