Abstract

This study examines the impact of energy prices on economic growth through a comparative analysis of Türkiye and Russia. The analysis uses annual data covering the period 2000-2024. The primary empirical assessment employs a multiple linear regression (OLS) model, with panel data techniques used as complementary methods to analyze long-run relationships and test the robustness of the findings. Brent crude oil prices are used as a proxy for energy prices, and the GDP growth rate serves as the indicator of economic growth. Unemployment, inflation, exchange rate, trade volume, and gross capital formation are included in the model as control variables. The findings indicate that Brent oil prices have a negative and statistically significant effect on economic growth. Moreover, the adverse effects of unemployment and exchange rate fluctuations on growth are stronger, whereas gross capital formation contributes positively to economic growth. The results of the interaction model reveal that the effect of oil prices does not differ significantly between the two countries. In conclusion, the impact of energy prices on economic growth is not direct but is shaped by macroeconomic conditions and varies with country-specific structural characteristics.

Abstract

This study examines the relationship between metaverse-ready digital infrastructure and logistics performance in BRICS economies. Although the metaverse is increasingly discussed as a transformative digital ecosystem for business, logistics, and supply chain operations, empirical evidence on its infrastructure foundations remains limited, particularly in emerging economies. To address this gap, the study constructs a Metaverse Infrastructure Index (MII) based on internet usage, fixed broadband subscriptions, mobile cellular subscriptions, and ICT service exports. The analysis covers five BRICS economies—Brazil, China, India, Russia, and South Africa—across seven years: 2007, 2010, 2012, 2014, 2016, 2018, and 2023. The final dataset comprises 35 country-year observations. Descriptive statistics, Pearson correlation analysis, multiple linear regression, and panel regression models are employed. Pooled OLS results do not reveal a statistically significant relationship between MII and logistics performance. However, both Fixed Effects and Random Effects models show that MII has a positive and statistically significant effect on logistics performance when country-specific heterogeneity is taken into account. The Hausman test indicates that the Random Effects model may be preferred. The findings suggest that metaverse-ready digital infrastructure can contribute to logistics performance in BRICS economies, but its effect becomes visible only when country-level structural differences are considered.
