Item Major weapons procurement: An efficiency‐based approach for the selection of fighter jets(John Wiley and Sons Ltd, 2020-06-01) Lu, Wen‐Min; Kweh, Qian Long; Nourani, Mohammad; Shih, Jui‐MinThis study applies the epsilon-based measure method in data envelopment analysis (DEA) to evaluate processes in procuring fighter jets (FJs), which are indicative of the technology and capability of major weapons. Moreover, multidimensional scaling analysis and sensitivity analysis were included to assess the selection of FJs. The DEA analysis indicates that the overall efficiency of the sample of 26 FJs was 0.824 on average. Besides, procurers rely on price and capability to decide which FJ models to purchase. Overall, the evaluation results can be provided to procurement decision makers even in selecting other types of major weapon in a cost-effective manner. © 2019 John Wiley & Sons, Ltd.Item Mutual fund performance: The decision quality and capital magnet efficiencies(John Wiley and Sons Ltd, 2020-07-01) Hsieh, H. Pierre; Tebourbi, Imen; Lu, Wen‐Min; Liu, Nai‐YuThis study employs a two-stage network data envelopment analysis model to analyze the decision quality and capital magnet efficiencies of 155 mutual funds in Taiwan during the period 2007–2016. The empirical results show that fund managers improved their decision quality; however, their capital magnet efficiency declined. This study also found 10 mutual funds performing in decision quality and capital magnet efficiencies, from which practical suggestions are provided to investors. Finally, this study constructs a market competition matrix to help fund managers (and investors) improve their operating and portfolio performance, plus resource allocation. © 2020 John Wiley & Sons, Ltd.Item What do U.S. biopharmaceutical companies get from patents and research and development spikes for their dynamic corporate performance?(John Wiley and Sons Ltd, 2020-07-01) Wang, Wei‐Kang; Lu, Wen‐Min; Kweh, Qian Long; Truong, Hoang Tu Nhi
