Operational efficiency in Taiwan banks with consideration of nonperforming loans: A dynamic network DEA
Get PDFThis workshop is supported by JSPS KAKENHI Grant Number 22310092 under the title “Theory and Applications of Dynamic DEA with Network Structure.”This paper applies a slacks-based measure dynamic data envelopment analysis (SBM-DNDEA) model to simultaneously evaluate overall, deposit, lending, period, deposit-period and lending-period efficiencies for 22 Taiwanese banks over the period from 1999 to 2011. We treat deposit as the intermediate output, and use non-performing loan as undesirable output capturing the effect of carry-over activity. The results indicate that the improvement in individual process has positive effect on banks’ performance, while efficiency in the deposit process may not guarantee efficiency in the lending process, and vice versa. The period efficiency for all banks has the stable variance. Besides, the efficiencies based on operational characteristics are further compared.Workshop 2013 on Dynamic and Network DEA (January 29-30, 2013)conference pape
Technical Efficiency Accounting for Environmental Influence in the Japanese Gas Market
Get PDFThis workshop is supported by JSPS KAKENHI Grant Number 22310092 under the title “Theory and Applications of Dynamic DEA with Network Structure.”This study measured technical efficiency accounting for environmental influence in the Japanese gas market by stochastic frontier analysis (SFA) and data envelopment analysis (DEA). The results showed that from the viewpoint of fitness, the stochastic frontier production function incorporating an external factor was more appropriate than one without it. The study also found that the distribution of efficiency scores calculated by the DEA model incorporating an external factor was more similar to that by the SFA model incorporating the factor, compared to that by the DEA model without incorporating it. These findings imply that considering the impact of external conditions on technical efficiency is essential for the Japanese gas market.Workshop 2013 on Dynamic and Network DEA (January 29-30, 2013)conference pape
DYNAMIC EVALUATION OF BATTERS IN NIPPON PROFESSIONAL BASEBALL LEAGUES – A NEW PROPOSITION RELATING TO MULTIPLIER BOUNDS IN DEA-AR –
Get PDFThis workshop is supported by JSPS KAKENHI Grant Number 22310094 under the title “Theory and Applications of Dynamic DEA with Network Structure.”In each of Nippon Professional Baseball Leagues (NPBL), only about twenty batters over 220 times at bat played during years 2008-2012. Therefore in evaluation of batters, we cannot use long time series data for the same batter. At first possibility of efficiency evaluation based on short past data is discussed. In the next place evaluations of batters based on batting orders is discussed. In such DEA models as CCR, multipliers which may cause bad effects for evaluation may be neglected, that is, the values of the corresponding multipliers may become 0. To improve this shortcoming, the assurance region methods, which have bounds relating to multipliers were proposed. We propose new methods based on the absolute deviation, by which the bounds are derived effortlessly from limited information, i.e., partial ranking data. The methods are applied to the evaluation of baseball players in NPBL.Workshop 2013 on Dynamic and Network DEA (January 29-30, 2013)conference pape
Dynamic DEA with network structure: -A slacks-based measure approach-
Get PDFThis workshop is supported by JSPS KAKENHI Grant Number 22310097 under the title “Theory and Applications of Dynamic DEA with Network Structure.”We propose a dynamic DEA model involving network structure in each period within the framework of a slacks-based measure approach. We have previously published the network SBM (NSBM) and the dynamic SBM (DSBM) models separately. Hence, this article is a composite of these two models. Vertically, we deal with multiple divisions connected by links of network structure within each period and, horizontally, we combine the network structure by means of carry-over activities between two succeeding periods. This model can evaluate (1) the overall efficiency over the entire observed period, (2) dynamic change of period efficiency and (3) dynamic change of divisional efficiency. In addition, we also introduce dynamic Malmquist index by which we can compare divisional performances over time. We applied this model to a dataset of US electric utilities and compared the result with that of DSBM.Workshop 2013 on Dynamic and Network DEA (January 29-30, 2013)conference pape
