Coffee is one of the most widely consumed beverages globally, with its consumption influenced by socio-economic factors, such as income levels, pricing, and regional preferences. This study examined the relationships between income and coffee consumption across different regions to analyze whether coffee behaves as a normal good. Using an unbalanced panel dataset from 53 countries, we incorporated key economic variables including Gross Domestic Product (GDP) per capita, coffee and tea consumption, and the prices of ground coffee and tea. A fixed-effects regression model was employed to assess the impact of income variations on coffee intake. The findings revealed significant regional disparities. For the European and African & Middle Eastern Regions, income showed a positive effect on coffee consumption when grouped with all variables. For the Asia–Pacific (APAC) and American regions, income within the regression showed no statistical significance whatsoever. Therefore, income appears, for half the regions, to be significant in determining coffee consumption, i.e., the more money one has, the more coffee they are able to consume, which reiterates that coffee is a normal good. These results contribute to the existing literature by providing a comparative regional analysis of income-driven coffee consumption. The findings also have practical implications for coffee producers, policymakers, and businesses seeking to understand market demands. Understanding regional coffee trends can support demand forecasting and pricing strategies. However, future studies should also examine consumer behavior and marketing dynamics.

This study examines how corporate social responsibility (CSR), measured through ESG performance, shapes innovation in China’s technology industry. The study uses a panel data regression model with firm, year, and industry-fixed effects, based on 22,963 firm–year observations from 1530 Chinese A-share high-tech firms during 2009–2023. Data were gathered from Chinese technology companies to examine the relationship between CSR/ESG performance and innovation indicators, including patent output and R&D intensity. The findings show that higher ESG performance is linked with stronger innovation outcomes. Specifically, a one-point increase in ESG score is associated with a significant rise in patent output (β = 0.1062, p < 0.01) and R&D intensity (β = 0.0019, p < 0.01). Results further suggest that CSR is positively associated with innovation performance, and environmental CSR appears to have the strongest effect on patent output among the ESG dimensions. Moreover, larger organizations obtain greater innovation advantages from CSR engagement. Using stakeholder theory, the Resource-Based View (RBV), and dynamic capabilities as theoretical foundations, the paper shows that long-term investments in CSR can support innovation performance. This study contributes to CSR–innovation research by providing longitudinal evidence from China’s technology industry and demonstrating that CSR/ESG engagement supports both innovation output and innovation input.

This study examines the relationship between governance quality and economic growth using panel data from 190 countries for the period 2005–2024. It provides updated global evidence on how institutional factors are associated with GDP growth while accounting for key macroeconomic conditions. Using a fixed-effects panel regression approach, the study finds that control of corruption and government effectiveness are positively associated with economic growth, although the effect of control of corruption is modest and should be interpreted cautiously. In contrast, regulatory quality and voice and accountability show significant negative short-term effects, likely reflecting transitional adjustment costs associated with reforms. Political stability and rule of law are not statistically robust in the final model, suggesting that their influence may be indirect or realized over longer time horizons. Among the control variables, foreign direct investment is consistently associated with higher growth, while public debt and short-term increases in education and health expenditure are linked to lower growth. The findings suggest that governance quality matters for economic performance, but its effects are conditional on broader institutional and macroeconomic contexts.

Purpose This study examines the relationship between self-efficacy, thinking style, and creative performance in Bangladeshi trade companies. Employee creativity is essential for organizational growth in competitive global markets. While self-efficacy has been researched in Western contexts, limited studies address its role in non-Western economies like Bangladesh. Research significance Prior studies often overlook the relationship between self-efficacy, thinking style, and job stressors, particularly in high-pressure work environments. This study addresses these gaps by examining how self-efficacy and thinking style contribute to creative performance and reassessing the role of job stressors in this dynamic. Methodology The research used a quantitative approach. Surveys were conducted with 300 employees, including 40 managers, managing directors, and chief operating officers from 40 Bangladeshi trade companies. Linear regression analysis tested the hypotheses, and additional analyses validated the relationships between key variables. Findings The results confirm that self-efficacy positively influences both thinking style and creative performance. Thinking style also significantly enhances employees’ creative performance. Contrary to initial expectations, job stressors do not moderate the relationship between self-efficacy and thinking style but emerge as significant independent predictors, highlighting their direct role in influencing cognitive processes. Contributions and novelty This study is among the first to integrate self-efficacy, thinking style, and job stressors in a non-Western trade sector. It offers an integrated framework for understanding how self-efficacy, and thinking style influence performance in trade companies. The study contributes to organizational behavior literature by examining these dynamics in Bangladesh’s trade sector. Implications The findings offer practical insights for managers in emerging economies. Managers should focus on building employee self-efficacy through targeted training. Promoting diverse thinking styles can further enhance creativity. These measures can improve employee creativity and organizational competitiveness.
