    Input aggregation bias in technical efficiency with multiple criteria analysis
    (Routledge, 2015) Aldanondo Ochoa, Ana María; Casanovas Oliva, Valero; Gestión de Empresas; Enpresen Kudeaketa
    We extend the Tauer (2001) and Färeet al. (2004) analyses of aggregation bias in technical efficiency measurement to multiple criteria decision analysis. We show input aggregation conditions consistent with multiple criteria evaluation of overall efficiency in conjunction with the variation in aggregation bias.

    Pollution shadow prices in conventional and organic farming: an application in a Mediterranean context
    (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2011) Arandia Miura, Amaia; Aldanondo Ochoa, Ana María; Gestión de Empresas; Enpresen Kudeaketa
    La agricultura ecológica integra criterios ambientales en las prácticas de producción agrícola con el objeto de mejorar el impacto de la producción agraria sobre el medio ambiente. En este trabajo se estiman y comparan los precios sombra de dos de los contaminantes más importantes en la producción agraria, el excedente de nitrógeno y la contaminación por pesticidas, en el contexto de la agricultura mediterránea. Los resultados muestran que el coste marginal de reducción de la contaminación es más alto para las explotaciones ecológicas que para las convencionales. Ello estaría indicando que la regulación de agricultura ecológica es de hecho más restrictiva ambientalmente que la de la agricultura convencional. En este sentido los resultados sugieren que la agricultura ecológica podría ser una respuesta adecuada a algunos de los problemas ambientales provocados por la agricultura convencional.

    Feed prices and production costs on Spanish dairy farms
    (Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2014) Aldanondo Ochoa, Ana María; Casanovas Oliva, Valero; Gestión de Empresas; Enpresen Kudeaketa
    This paper analyses the impact of livestock feed prices and pasture quality on the long and short-term costs of milk production in a region of Spain (Navarre). The empirical results are obtained from the estimation of a flexible shortrun cost function, followed by the approximation of long-run equilibrium based on the quasi-fixed factors adjusted to their optimal levels. The results reveal a high sensitivity of milk production costs to changes in livestock feed prices due to two reasons. One is that, as milk production expands, it tends to become technologically more intensive. The other is that, in the current structure of dairy farming, land input is suboptimal, particularly in the case of large farms and areas of poor pasture. The results reveal that short-run substitution between feed and livestock is a potential strategy for farms to respond to feed price increases. They also suggest that structural policies designed to strengthen the dairy sector’s competitiveness should vary according to agro-climatic conditions. In areas of poor pasture, herd growth might be used as a long-term measure to increase competitiveness through economies of scale
