We investigate the relationship among managerial overconfidence (MO), government ownership, and research and development (R&D) investment using data from Vietnamese public companies for the period 2007–2016. We also investigate how R&D investment, given MO and government ownership, affect future firm performance. Our results indicate that MO and government ownership are positively related to R&D investment. Conceptually, this study investigates novel factors affecting of R&D investment and their role in improving firm performance. Overall, this study emphasizes the importance of R&D investment in the corporate world, improving firm performance and, ultimately, economic prosperity.

This study utilizes mediation analysis and bootstrapping to analyze the mediating effect of capital structure on the association between managerial ability and firm performance. The dataset consists of 6384 firm-year observations from the Taiwanese electronics industry during 2005–2018. Our results indicate that (1) low (high) levels of debt are likely observed in firms with CEOs with high (low) ability, (2) managerial ability positively affects firm performance, and (3) capital structure mediates the positive relationship between managerial ability and firm performance. Overall, the findings may have limited generalizability due to the specific sample characteristics and provide convincing support for the importance of capital structure as a mediator in the managerial ability-firm performance nexus. Specifically, this study highlights the need for examining the effect of managerial ability on firm performance through a mediator.

This study investigates the relationship of innovation capital and corporate social responsibility (CSR) with business performance. The sample is from 33 manufacturing companies that won the 2016 Corporate Citizenship Award of CommonWealth Magazine. Empirical analysis result shows that the average technical efficiency (TE) of the 33 corporate citizens is 0.835. Among companies, nine companies are relatively efficient, 24 companies are in scale inefficiency, and 20 companies are in mixed inefficiency. The relationship between the CSR total score and TE fails to reach a significant level, reflecting no significant association between the CSR total score evaluation result and TE value.

This 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.
