Contribución al estudio de la fijación de precios diferentes a las distintas calidades de hullas españolas

Abstract

[ES] Tras unas breves consideraciones sobre la posibilidad y conveniencia de fijar precios diferentes a las distintas calidades de hullas que se producen en España, se propone una clasificación comercial en seis grupos, definidos por las materias volátiles y el índice de hinchamiento al crisol. Se hace la distribución de los seis grupos propuestos de la producción española de hullas del año 1955, ya continuación se exponen las ideas generales en que se apoya una propuesta de escala de precios para los menudos de hullas de los seis grupos. Partiendo de los actuales precios de tasa, iguales para todas las calidades de hullas, se proponen unas fórmulas que, en función de un parámetro, dan los precios base y las primas por calidades de los granos, menudos, finos y schlamms de hulla producidos en las provincias de Oviedo, León y Palencia. Finalmente, se aplican estas fórmulas a tres valores del parámetro.

[EN] After some brief considerations about the possibility and convenience to settle different prices for the various qualities of coals produced in Spain, a commercial classification into six groups is proposed in the paper, each one defined by the volatile matter and the crucible swelling number. It is made a distribution in the six groups: proposed for the Spanish production of coals on the year 1955, and next, the general lines on which is based a proposed scale of prices for the fines 1-10 mm of the six groups, are also exposed. Starting from the present prices, fixed by the Government and equal for all qualities of coals, it is proposed a series of formulas which give the base prices and premiums for qualities of the different calibrated sizes produced in the provinces of Oviedo, Le6n y Palencia. Finally, these formulas are applied to three different cases.
