This is an academic research article that analyzes the quantitative relationships between exchange rate volatility and multiple economic variables including GDP growth, inflation, domestic and foreign investment, industrial value added, savings, per capita income, trade openness, external debt, and public spending. The study employs a GARCH model to estimate exchange rate volatility and uses cointegration techniques and bounds testing to explore long-term dynamic effects through autoregressive distributed lag regression methods.
