| Tiivistelmä: | This paper discusses returns to scale (RTS) in data envelopment analysis (DEA) for each of the presently available types of models. The BCC (Banker, Charnes and Cooper) and CCR (Charnes, Cooper and Rhodes) models are treated in input oriented forms while the multiplicative model is treated in output oriented form. Quantitative estimates in the form of scale elasticities are treated in the context of multiplicative models, but the bulk of the discussion is confined to qualitative characterizations such as whether RTS is identified as increasing, decreasing or constant. This is discussed for each type of model and relations between the results for the different models are established. |
