This article identifies different groups in a cost function framework of soccer clubs in the Spanish Football League First Division. In particular, we have clustered the sample— comprising data for seasons 1994/1995 to 2004/2005—into three groups. To do so, we have implemented a...

This article analyses technical efficiency of football clubs in the Spanish Football League Division 1 (Primera Liga) from the seasons 1995-1996 to 2004-2005 with an unbalanced panel data. The random frontier model is used, allowing the identification of random variables in the cost frontier. It...

Using the random stochastic frontier model, this paper examines the technical efficiency of the English football Premier League from 1998/99 to 2003/04. The model disentangles homogenous and heterogeneous variables in the cost function, which leads us to advise the implementation of common...
