“…This is a method that has been very well received in the scientific community. Its main advantage lies in the fact that it relaxes the requirement for the “strict” exogeneity of inputs; they only have to be predetermined variables (Okoyeuzu et al 2021 ; Yao et al 2022 ). Thus, four models have been built with the following specifications: …”

The EU supports agricultural policies to help farmers meet the challenges of climate change (CC) by promoting more sustainable and environmentally friendly practices. This study focuses on the European primary sector (agriculture, forestry, and fisheries), productive activities that meet humanity’s basic needs, although this sector does not account for a dominant share of GDP. The analysis uses a panel data sample of 22 European countries for the period 2012–2019, and seeks to answer the following research questions: Is there a direct relationship between agricultural innovation efficiency and the technological advances implemented? What effect do GHG emissions and innovation efficiency have on CC? Which agricultural practices have the greatest effect on the volume of GHG emissions? The results indicate that the European primary sector has registered an average rise in productivity of 4%, mainly driven by technological improvements. This underscores the need for agricultural innovation policies that focus not only on improving aspects related to technology but also on making better use of existing resources. In addition, the econometric models estimated confirm that efficiency levels are the most influential determinants of temperature change, while GHG emissions are primarily explained by their own historical values. Ultimately, research and development is a tool that can be used to curb CC, along with the proper use of land and fertilizers. There is thus a need to foster novel agricultural practices that help reduce emissions while ensuring the efficiency of the sector.

“…Other methodologies, like two-or three-stage least squares analysis (2SLS or 3SLS) for running simultaneous equations, produce inconsistent parameter estimates for dynamic models (García-Meca et al, 2015). Moreover, we solved two fundamental problems using the GMM system method -endogeneity and unobserved heterogeneity (Djalilov and Piesse, 2016;Okoyeuzu et al, 2021;Proença et al, 2020;Vieira et al, 2019). This methodology combines an equation in levels, where explanatory variables in first differences are used as instruments and an equation in first differences where level explanatory variables are used as instruments (Farag and Mallin, 2018) nonsignificant parameters jointly) (Munjal et al, 2019).…”

Purpose This paper aims to analyze the performance determinants of listed companies in the Iberian Peninsula, focusing on the analysis of the effect of gender diversity and the structure of the board of directors. Design/methodology/approach To achieve this aim, the authors analyzed 97 listed companies, of which 23 are Portuguese and 74 are Spanish, between 2015 and 2019. The authors use Arellano and Bond’s (1991) generalized method of moments system model to test the hypotheses. Findings The results show an important impact of corporate governance variables on corporate performance. Specifically, board size, average director age and board academic qualifications are crucial to explaining profitability and market value. Moreover, the authors identified a nonlinear relationship between gender diversity and profitability and market value levels due to critical mass theory and quotas that enhance more social justice. The authors concluded that the corporate performance determinants differ depending on the performance measures. Originality/value To the best of the authors’ knowledge, this study is the first to analyze the nonlinear effect of gender diversity and board structure (size, educational qualifications and average director age) on the performance of Iberian listed companies as a single market.

“…When researching the characteristics of the CEO affecting bank performance in Indonesia and India, Endraswati (2018) and Handa (2019) suggested that commercial banks under female CEOs have lower business performance than commercial banks run by male CEO. According to Lafuente and Vaillant (2019) and Okoyeuzu et al (2021), gender diversity is essential in improving a commercial bank's business performance. However, this result is only meaningful when there is no participation of women in senior executive positions such as Chairman of the Board of Directors or Chief Executive Officer.…”

Purpose This study aims to evaluate the impact of board characteristics on bank performance at the commercial bank in Vietnam. Design/methodology/approach By running the pool OLS, fixed-effect and random-effect models with a panel data set of 294 observations from 2008 to 2021, the authors have examined determinants of bank performance. Findings The research results show that bank size, governance efficiency, capital adequacy ratio and economic growth have a positive effect while credit risk has a negative relationship with the commercial bank’s performance. Originality/value In particular, the result shows the relationship between chief executive officers’ (CEOs) gender and bank performance. Commercial banks led by female CEOs have lower bank performance than that led by male CEOs. However, this impact magnitude is not significant. The research results are the basis to propose recommendations to improve the Vietnamese commercial bank’s performance.
