    Asymmetric linkages between public-private partnership, environmental innovation, and transport emissions
    (Routledge Journals, Taylor & Francis Ltd, 2022) Liu, Li; Anwar, Ahsan; Irmak, Esma; Pelit, Irem
    No one denied the significant role of transportation infrastructure in economic development; however, it is also considered a major contributor to global warming. Therefore, to achieve sustainable development, it is imperative to transform the transport sector investment into low-carbon transportation choices. The public-private partnership investment in the transport sector could be proved a suitable tool for sustainable transport and efficiency. Therefore, we investigate the significance of public-private partnership investment (PPP) on transport emissions by incorporating the role of environmental innovation, economic growth, and population. Our preliminary findings confirm that all variables are abnormally distributed and embodied with structural breaks that distort true parameters in traditional regression. In compliance, we employ Quantile ARDL (QARDL) technique which provides more reliable results in case of non-normality, dynamic trends, and structural changes in data. The long-run empirical outcomes indicate that PPP reduces transport emissions mainly from middle (40th) to highest (95th) emissions quantiles. Similarly, environmental innovation reduces transport emissions from 60th to 95th quantiles. These results imply that the emissions-mitigating effect of PPP and environmental innovation is only pronounced at higher levels of transport emissions. The results provide valuable policy recommendations.

    Does freight and passenger transportation industries are sustainable in BRICS countries? Evidence from advance panel estimations
    (Routledge Journals, Taylor & Francis Ltd, 2022) Zhang, Huixin; Razzaq, Asif; Pelit, Irem; Irmak, Esma
    Freight and passenger transportation profoundly impacts environmental degradation due to the higher fossil fuel consumption and respective emissions. Therefore, this study explores the impact of freight and passenger transportation on environmental pollution (particulate matter 2.5(PM 2.5)) in BRICS countries using annual data from 1990 to 2018. We employed various advanced econometric approaches to handle issues arising from panel data, such as the presence of unit root, cross-sectional dependency, structural break, and parameters heterogeneity. The overall results show that freight and passenger transportation significantly contribute to a higher concentration of PM 2.5; however, the impact of freight transportation is almost double that of passenger transportation. Similarly, economic growth also caused higher environmental pollution. Moreover, this study confirms the presence of the Environmental Kuznets Curve hypothesis in the long run. These results provide valuable suggestions to achieve a sustainable environment.

    The Dynamic effects of Foreign Direct Investment Services and Energy Consumption on Information and Communication Technology Sector
    (Econjournals, 2023) Rawoof, Hira Abdul; Said, Laila Re Iana; Irmak, Esma; Pelit, Irem; Shabbir, Malik Shahzad
    This study scrutinises the influence of foreign direct investment (FDI) inflows, energy consumption on Information and Communication services (ICTs) in selected economies of South Asia. This research is based on heterogenous and second generation framework of panel data-set from 1999 to 2021. This study used augmented mean group (AMG), mean group (MG), and common correlated effects mean group (CCEMG) assessors, which further promotes the substantial and favourable influence of FDI services, and energy consumption on ICTs. However, the impact of terrorism is insignificant on ICTs in the region of South Asia. The results indicate that economies of these region must embrace investment reform measures in order to draw FDI into the services sector, increase exports of services, and progress towards economic stability. © 2023, Econjournals.

    The Dynamic Relationship among Domestic Stock Returns Volatility, Oil Prices, Exchange Rate and Macroeconomic Factors of Investment
    (Econjournals, 2023) Shabbir, Malik Shahzad; Said, Laila Refiana; Pelit, Irem; Irmak, Esma
    This study investigates the impact of oil price variations, exchange rates, macroeconomic factors and domestic stock volatility in selected south Asian countries. This study employs a general autoregressive heteroskedastic (GARCH) model using quarterly data from 2001 to 2021. The results reveal that there is a significant relationship between the domestic stock of credit and macroeconomic factors. We find surprising results for the set of the countries; there is a negative impact of asset portfolio investment in the domestic stock for Bangladesh, and Pakistan. There is a positive impact on the economic growth in the majority of countries with the exception of Pakistan and Bangladesh. Inflation seems to increase while there is an increase in the credit in the economy. © 2023, Econjournals. All rights reserved.
