Due to the strategic objectives, multidisciplinary theatres offer drama as well as music and dance events. If we measure efficiency of these theatres by DEA, it is inappropriate to neglect a discipline when efficiency bases on it. Hence, the efficiency structure has to be observed. Moreover, some of these theatres operate under specific conditions which require a categorization. As decision makers are interested in efficiency changes over time we introduce a so called dynamic RC-DEA model that incorporates all these requirements. The RC-DEA is based on an application-oriented implementation of weight restrictions in the multiplier model. A hierarchically categorical DEA is embedded in combination with a Window Analysis. In contrast to this well-known dynamic approach we recommend a modified measure for a window. The use of the RC-DEA model is illustrated by an empirical example of 31 German public multidisciplinary theatres.
