Abstract: This study explores the economic performance that vicarious warfare can bring for the aerospace and defence industry. First, this study measures the performance of 22 companies using a nonradial dynamic data envelopment analysis model from 2011 to 2017. Second, this study evaluates whether vicarious warfare can influence the performance. The efficiency analysis suggests rooms for improvements meanwhile, the projection analysis suggests that market value should be significantly increased, and the number of employees should be reduced significantly. The regression analysis suggests that the number of times a country takes a side in wars would positively affect the efficiency of companies.

TL;DR: In this article, the authors examined the managerial performance efficiency of 36 globally leading telecommunications operators by utilizing the data envelopment analysis (DEA) technique and found that the scale of the operators does play an important role in influencing their operating efficiency.

TL;DR: In this article , the authors examined the efficiency of investment trust companies (ITCs) from 2011 to 2020 using a meta-frontier two-stage network data envelopment analysis (DEA) based on the directional distance function (DDF).

TL;DR: In this article, the authors investigated the effects of intellectual capital and risk management on the efficiency performance of Malaysian general insurers and employed data envelopment analysis (DEA) to estimate efficiency performance.
