“…This obtains performance rankings that are robust with respect to the specific weighting scheme that is used: an observation is DEAdominated if for each possible weighting scheme (i.e., including the "most favorable" scheme) there is another observation that obtains a higher aggregate index value. DEA has recently been applied within a sports context (e.g., De Oliveira & Callum, 2004;Einolf, 2004;Haas, Kocher, & Sutter, 2004;Lozano, Villa, Guerrero, & Cortés, 2002) and within a cross-country policy evaluation context (e.g., Cherchye, 2001;Cherchye & Kuosmanen, 2004;Cherchye, Moesen, & Van Puyenbroeck, 2004;Evans, Lauer, Lovell, & Murray, 2002).…”
