Purpose This study aims to contribute to the extant literature on logistics by investigating the interrelationship between the financial performance of listed logistics firms and the COVID-19 and compare the logistics firms’ financial performance of G-20 countries during the pandemic period. Design/methodology/approach To conduct the confirmatory analysis by testing the hypotheses formulated for this study, data have been collected from Bloomberg of all logistics firms from G-20 countries. This paper gathered the first quarter from 2010 until the last quarter of 2020 as the research sample to examine the pandemic impact on financial performance. Findings The results show that the financial performance of logistic firms was significantly higher during 2020. Overall, the country-wise findings corroborated with the main results and the financial performance of 14 countries’ logistic firms out of 20 ones analysed has been significantly elevated, during the pandemic period. However, this paper has found out a negative financial performance of the logistics firms during the COVID-19 period in six countries (Germany, Korea, Russia, Mexico, Saudi Arabia and the UK), which support the second proposition. Research limitations/implications The study’s results were important as they highlighted the role of logistics firms in offering insights to academics, practitioners, policymakers and logistic firms’ stakeholders. For future research, this paper suggests including some other variables that might influence firm performance and that have not been considered in this study, which is a limitation, and going more deeply into the logistics sector by comparing the financial performance of the sub-sectors. Practical implications As the importance of logistics services during the pandemic period is relevant, this study may provide significant insights because the logistics firms play a crucial role by anticipating to ensure the supply of essential items such as food, medicine, then supporting for the continuity of supply chains. The view of finance impacts during the pandemic may provide insightful perspectives for logistics companies, allowing them to understand those impacts and better prepare for likely disruption events such COVID-19 pandemic. Originality/value This paper is novel considering that it is unique in evaluating logistics firms’ financial performance from a global perspective, considering the context of this historical pandemic.

In this paper, we examine whether the projects of the United States (U.S.) corporations have implemented initiatives to reduce the environmental footprint of their supply chains during coronavirus (COVID-19). Environmental footprint reductions could be achieved by reducing waste, reducing resource use, and reducing ecological emissions by introducing environmental management systems in the supply chains. For this aim, the project’s initiatives play a crucial role. This study has the primary purpose of examining the impact of ecological footprints on financial performance achieved by US corporations’ initiatives implemented through projects during the COVID-19 period. The final sample comprises 9997 company-year observations over the investigation period between 2010 and 2020. The results suggest that firms implementing the initiatives to reduce environmental footprint have shown a significant positive financial performance during the COVID-19 period. The results are robust to alternative specifications of informativeness and sensitivity tests controlling for time-invariant firm characteristics and alternative firms' performance measures. Our results corroborate with stakeholder theory, which implies implementing green policies will alleviate the agency issue and safeguard the shareholders' interest. Moreover, it clearly demonstrates the positive impact of environmental projects-focused organizations on the financial and environmental performance even while challenging and disrupting situations such as this unprecedented pandemic.

The cumulative capacitated vehicle routing problem (CCVRP) is a relatively new version of the classical capacitated vehicle routing problem, and it is equivalent to a traveling repairman problem with capacity constraints and a homogeneous vehicle fleet, which aims to minimize the total arrival time at customers. Many real‐world applications can be modeled by this problem, such as the important application resulting from the humanitarian aid following a natural disaster. In this paper, two heuristics are proposed. The first one is a constructive heuristic to generate an initial solution and the second is the skewed variable neighborhood search (SVNS) heuristic. The SVNS algorithm starts with the initial solution. At each iteration, the perturbation phase and the local search phase are used to improve the solution of the CCVRP, and the distance function in acceptance criteria phase is used to improve the exploration of faraway valleys. This algorithm is applied to a set of benchmarks, and the comparison results show that the proposed algorithms provide better solutions than those reported in the previous literature on memetic algorithms and adaptive large neighborhood search heuristics.

PurposeThis study investigates the impact of green supply chain management (GSCM) practices on environmental performance in firms operating in the discretionary sector in the G20 countries. The sample covers 749 firms for the period 2010–2020.Design/methodology/approachThis study combines qualitative and quantitative data to examine the impact of the implementation of GSCM on accounting performance measured by the operating margin (OM) and return on assets (ROA). The authors also moderate the effects of Six Sigma and quality management (QM) and ISO 9000 and control for firm variables and COVID 19.FindingsUsing a panel data regression and structural equation modeling (SEM), results indicate that discretionary firms with internal solid GSCM practices combined with external environmental monitoring of suppliers are likely to outperform their peers in environmental issues. Using hierarchical regression, results indicate that both ISO 9000 and S&QM have moderating effects at some level of performance. Furthermore, environmental performance is positively correlated with accounting performance. This study contributes to the literature by addressing the impact of GSCM and the importance of reinforcing green and social regulations to protect the planet.Originality/valueThe paper is one of the first to measure GSCM triple components and account for COVID-19 in the context of discretionary companies and G20 countries. It highlights the impact of green initiatives to cope with major disruptions and decrease pollution and environmental disasters.
