A Bootstrap DEA Analysis A1 Gil Ropero, Antonio A1 Cerbán Jiménez, María del Mar A1 Camarero Orive, Alberto A1 Parra Santiago, José Ignacio A1 Turias Domínguez, Ignacio José A2 Economía General A2 Ingeniería Industrial e Ingeniería Civil A2 Ingeniería Informática K1 Pure Technical Efficiency K1 Data Envelopment Analysis K1 Bootstraps AB This paper measures the growth in pure technical efficiency of Spanish PortsSystem from 2017 to 2018 in order to assess trends in the overall throughput. The secondobjective is to produce more realistic efficiency estimations guaranteeing the independency of the selected sample of Ports. The results of the analysis indicate that the bootstrapped DEA (Data Envelopment Analysis) method is significantly different to classical DEA estimations.The evidence suggests that the greatest differences among the values of DEA efficiencyand Bootstrap efficiency are most significant in those ports with original efficiency equalto one. This is more relevant Valencia (13.33%), Barcelona (14.62%), Cartagena (14.64%),Huelva (15.67%), Motril (22.01%), Algeciras Bay (25.20%) and at a lower level to Melilla(28.28%), Baleares (28.85%) and Ceuta (28.91%).
