    Diseño de indicadores para medir la siniestralidad laboral: el caso español
    (Grupo Editorial Espacios GEES, 2019-09-23) sanchez larrion, Raul; Rodas Alfaya, Leticia
    El objetivo de este trabajo es diseñar una serie de indicadores que permitan analizar los accidentes laborales teniendo en cuenta las particularidades regionales. Se construirán tres grupos de indicadores. El primero relaciona los accidentes de trabajo con las características del trabajador y del mercado laboral, el segundo relaciona los accidentes de trabajo con las horas trabajadas y el tercero establece una relación entre los accidentes y el coste-beneficio que genera un trabajador en una empresa

    Innovation Efficiency in the Spanish Service Sectors, and Open Innovation
    (2021-03) Leguey Galán, Santiago; Cid Cid, Ana I; Rodas Alfaya, Leticia; Guede Cid, Rocío
    This paper analyzes the relationship between efficiency and innovation activity in Spanish industrial and service sectors by introducing a new methodology framework. A new model combining principal component analysis (PCA) and data envelopment analysis (DEA) is applied in order to obtain an efficiency score. To achieve a more comprehensive evaluation, a large dataset is included, but a large number of variables compared with the number of decision-making units (DMUs) may diminish the discriminatory power of DEA. To avoid this effect, we first apply PCA to separately obtain the input and output main factors. We then apply DEA to the new variables. The PCA–DEA model allows us to identify 5 efficient sectors out of 42. If only DEA were applied, 16 sectors would turn out to be efficient. This shows that the model improves the discriminatory capability of DEA. Methodologically, this work contributes to the literature by proposing an efficiency measurement using a large number of inputs and outputs that could be applied in different fields. Likewise, this analysis allows for the evaluation and interpretation of innovation activity in the different sectors, which can be taken into account in the management and allocation of resources by institutions.
