Hodnocení vybraných přístupů pro měření efektivnosti fotbalových klubů

This thesis addresses a gap in the existing literature on efficiency evaluation of football clubs using Data Envelopment Analysis (DEA). Although a substantial number of studies have been published in this area, there is currently a lack of research systematically assessing their methodological quality. This thesis partially fills this gap by replicating three selected studies evaluating the efficiency of football clubs using DEA, and subsequently examining their methodological quality while subjecting the obtained results to sensitivity analysis. The replication and sensitivity analysis were conducted on clubs from the top tier league of English football in the 2021/22 – 2023/24 seasons. The results indicate that authors often neglect to perform correlation analysis of variables and return to scale tests before selecting the final model specification. Furthermore, bootstrap methods to reduce bias in efficiency estimates are generally not applied. Some variables show a strong influence on the resulting efficiency scores, suggesting that variable selection should always be supported by thorough sensitivity analysis.
