Abstract
This study aims to examine the impact of technological innovation on the carbon emissions of the G20 economies while accounting for the moderating role of economic policy uncertainty. To analyze the relationship between emissions and technological innovation in the presence of economic vulnerabilities, the study used the annual data from 2000 to 2023. Panel and quantile regression are used to test the heterogeneous relationship. The results reveal that research and development expenditure (R&D) has a positive and statistically significant impact on emissions at certain quantiles, suggesting that innovation alone may not uniformly contribute to emission reductions. Economic policy uncertainty is documented to have a heterogeneous relationship with emissions, wherein it reduces emissions at lower quantiles, with a positive relationship exhibited at higher quantiles. Similar results are obtained when economic policy uncertainty and R&D interact and are able to reduce emissions at all levels, as shown by quantile regression. The results provide valuable implications for policymakers, emphasizing the importance of fostering innovation while managing policy uncertainty to achieve carbon mitigation goals across varying emission levels within the G20.

Impact of organizational politics on proactive behavior of government employees: the moderating role of self-efficacy
Problems and Perspectives in Management Volume 18, 2020 Issue #1 pp. 385-393 Views: 1929 Downloads: 438 TO CITE АНОТАЦІЯIn today’s organizational environment, human resources are seen to be one of the most crucial assets that must be maintained, particularly the existence of employees’ proactive behavior, which is needed for the sustainability of organizational performance. One factor, which may affect the employees’ proactive behavior, is organizational politics. Therefore, the main objective of this study is to investigate the effect of organizational politics on proactive behavior of government employees and to test further whether this effect was moderated by self-efficacy. This study used a quantitative approach with an exploratory method to answer the proposed hypothesis. The samples were 310 local government employees in Bandung district, Cimahi City, Bandung City, and West Bandung Regency, Indonesia. For processing the data and testing the hypotheses, this research employed Moderated Regression Analysis by using STATA 13. The results showed that organizational politics has a negative effect on the proactive behavior of government employees, and the moderation effect of self-efficacy can weaken the negative relationship between organizational politics and proactive behavior. The study, therefore, makes a valuable contribution regarding the additional evidence to the organization within this field.

Role of institutional quality in economic development: A case study of Asian countries

Problems and Perspectives in Management Volume 19, 2021 Issue #2 pp. 357-369 Views: 1853 Downloads: 1984 TO CITE АНОТАЦІЯThe paper investigates the impact of institutional quality on economic growth by taking 48 countries in Asia between 2005 and 2018. By using the quantile regression methods with panel data, institutional quality is found to be a key factor of economic development. However, in the lower-income Asian countries, the institution with better quality appears to promote the growth more effectively than in the higher-income ones. Moreover, the paper also finds out a nonlinear relationship between institutions and economic growth. The results show that there is an institutional threshold for economic growth to reach its highest level. If the institution indicator exceeds the threshold, it causes the reverse effect on the growth. Moreover, the economic growth of Asian countries is also affected by inflation (INF), labor force (LABO), trade openness (OPEN), and infrastructure (TELE). From that, the study suggests some policy implications for Asian countries and Vietnam, in particular, in order to improve institutions contributing to economic growth.

Work-family conflict and professional commitment: proactive effect of transformational leadership
Problems and Perspectives in Management Volume 18, 2020 Issue #1 pp. 97-106 Views: 1422 Downloads: 313 TO CITE АНОТАЦІЯThe study aims to empirically test the moderation effect of transformational leadership characteristic on the relationship between work-family conflict and professional commitment among school teachers. A cross-sectional study was conducted among 752 teachers currently working in private schools from selected districts in Tamil Nadu, India. Purposive sampling technique is used, and data were collected using a questionnaire. The moderating effect of transformational leadership behavior is examined using hierarchical regression analysis. Grounded with the conservation of resource theory (COR) and transformational leadership theory, the results supported the negative impact of work-family conflict on the professional commitment of teachers. Further, the moderation effect of transformational leadership found to reverse the negative relationship between work-family conflict and professional commitment. Thus, the transformational leadership behavior of leaders (head/principal) was found to foster the professional commitment of teachers. This study is focused only on the dimensions of transformational characteristics on the relationship between work-family conflict and professional commitment of teachers. Also, it would be constructive to examine other mediating or moderating impacts of variables such as peer support, job satisfaction, which can also have a significant impact. Further, the outcome variable related to the perspective of students can also be researched.
