This study looked at how investment, exports, and interest rates affect the economy in Yemen. They used economic data and special analysis methods to understand the relationships between these factors and the country's overall economic output. The researchers found that when investment goes up by 1%, the gross domestic product (GDP) went up by 28.63%. Increasing exports by 1% also led to a 69.76% GDP boost. However, a 1% increase in interest rates caused GDP to drop by 19.54%. The study suggests that more stable political and economic conditions could make investments even more beneficial, and that focusing on infrastructure and boosting exports are key for economic growth in Yemen.
