Gangless cross-evaluation in DEA: an application to stock selection

Abstract: This paper discusses the impact of ganging decision making units (DMUs) on the cross-efficiency evaluation in data envelopment analysis (DEA). A group of DMUs are said to be ganging-together if the minimum and the maximum cross-efficiency scores they give to all other DMUs are identical. This study demonstrates that the ganging phenomenon can significantly influence the cross-efficiency evaluation in favour of some DMUs. To overcome this shortcoming, we propose a gangless cross-efficiency evaluation approach. … Show more

“…Finally, the relationship between these coefficients and stock price from the perspective of reporting risk was correlated, thus proving the model's validity. DEA was used in [10][11][12]. The DEA model was used to determine the efficiency score of stock companies and then selected the stocks with high efficiency.…”

“…Deng and Fang [6] incorporated a DEA prospect cross-efficiency evaluation into an innovative MVM (mean-variance-maverick) framework for fuzzy portfolio selection. Amin and Oukil [2] and Sanei and Banihashemi [19] effectively applied the cross-efficiency evaluation for portfolio section.…”

“…Tavana et al () utilize DEA to screen the efficient PPs, which are isolated and ranked separately using TOPSIS. Nonetheless, by discarding inefficient PPs, the authors disregard the ganging phenomenon (Amin & Oukil, ) that often affects the ranking.…”
