Analyzing the connection between military expenditure and economic growth is interesting due to its policy implications, particularly in geopolitically strategic regions. In the case of Azerbaijan, where defense spending accounts for a significant share of the national budget, this relationship is especially relevant. The present study explores the long-term equilibrium between military expenditure, expressed as a percentage of GDP, over a three-decade period marked by consistent economic growth and substantial defense investments. To investigate this relationship, the study applies the Johansen cointegration method to check for a stable long-term relationship. It employs the Granger causality test to determine the causal direction between the variables. The findings show cointegrating relationships, indicating a long-term equilibrium between military expenditure and economic growth. Furthermore, the Granger causality analysis indicates a bidirectional causal link, implying that changes in military expenditure influence GDP per capita growth and vice versa. Specifically, the results show that military expenditure Granger causes GDP per capita at a lag of 3 (p-value = 0.012). Similarly, GDP per capita Granger causes military expenditure at the same lag (p-value = 0.0001). The findings reveal the dual impact of military spending on economic development, providing insights for Azerbaijani policymakers to balance defense needs with economic growth.

The paper investigates the causal interaction between renewable energy consumption and manufacturing value added in Kazakhstan, a relationship of growing importance in the context of sustainable industrial development. The aim of the study is to assess the direction and nature of causality between these variables over the period from 2000 to 2021. To this end, the Toda-Yamamoto Granger causality test is applied, offering robust results regardless of the order of integration of the time series data. The empirical analysis identifies a statistically significant bidirectional causal relationship. Specifically, renewable energy consumption has a significant impact on manufacturing value added (p = 0.003), while manufacturing value added also significantly influences renewable energy consumption (p = 0.006). These findings reveal a reciprocal mechanism in which the expansion of renewable energy supports industrial growth, and industrial development, in turn, enhances renewable energy usage. The results underscore the strategic importance of integrating renewable energy policies with industrial development plans. From a policy perspective, the study provides practical insights into fostering sustainable economic growth by aligning environmental and industrial objectives in Kazakhstan.
