The Investment and GDP Paradox: Why Doesn't High Economic Growth Always Drive Investment?

Abstract

The relationship between investment and Gross Domestic Product (GDP) is commonly perceived as linear, where an increase in GDP is expected to stimulate a rise in investment, and vice versa. However, this research suggests that this connection is not universally applicable, especially during periods of economic volatility. Using a simultaneous model, the study examines the correlation between investment, GDP and the macroeconomic variables that influence both, such as interest rates, money supply, inflation, fiscal policy, and foreign direct investment. The results from the Two-Stage Least Squares (TSLS) and Generalized Method of Moments (GMM) methodologies indicate that while GDP positively impacts investment, GDP growth does not consistently lead to increased investment under certain conditions. This inconsistency can be attributed to factors such as policy risk, economic uncertainty, and various structural elements. These findings have important policy implications, emphasizing that efforts to promote economic development should be paired with measures that create a more stable and sustainable investment environment. This research contributes to the existing literature by offering a fresh perspective on the complex relationship between investment and GDP, providing valuable insights for policymakers aiming to improve the effectiveness of economic growth strategies.
