Managerial Effiency in German Top League Soccer

This study applies stochastic frontier analytic techniques in the
estimation of sporting production functions. As ex ante input
factors, we use pre-seasonal estimates of wage bills of players and
coaches that are transformed during the production process of a
season into ex post pecuniary revenues and sporting success. While
in the case of athletic output we find a robust pattern of
technical efficiency over subsequent seasons, the estimates based
on economic output highlight the instability of the German soccer
industry.
