The Dynamics of Fiscal and External Imbalances: An Empirical Analysis of the Budget and Trade Deficits in Morocco
摘要
This paper presents a comprehensive empirical investigation into the relationship between the budget deficit and the trade deficit in Morocco, a developing economy characterized by its strategic geographical location and significant economic reforms. Utilizing time-series data spanning five decades, from 1970 to 2019, this study employs a Vector Autoregression (VAR) model to explore the dynamic interactions between these two critical macroeconomic variables. The methodology involves rigorous tests for stationarity and cointegration, followed by impulse response analysis and variance decomposition to elucidate the short-term and long-term impacts of budgetary changes on the trade balance. The stationarity tests, including the Augmented Dickey-Fuller and Phillips-Perron tests, reveal that both the budget balance and trade balance series are non-stationary at level but become stationary after differencing, indicating an integration order of I(1). The Johansen cointegration tests, however, indicate an absence of long-term equilibrium between the budget and trade balances, suggesting that these variables do not move together over the long run. Impulse response analysis provides deeper insights into the dynamic relationship, showing that a positive shock to the budget balance leads to an immediate and persistent improvement in the trade balance, consistent with the twin deficits hypothesis. Conversely, shocks to the trade balance have a negligible positive effect on the budget balance. Variance decomposition analysis further highlights the significant influence of budgetary shocks on the trade balance, accounting for approximately 37% of its variability over a 10-year horizon, while the impact of trade balance shocks on the budget balance remains minimal. These findings have substantial implications for fiscal and economic policy in Morocco. They underscore the critical role of fiscal management in influencing trade outcomes, suggesting that efforts to reduce the budget deficit could lead to favorable improvements in the trade balance. This is particularly relevant for policymakers aiming to achieve sustainable economic growth and stability. The study's results provide a nuanced perspective on the fiscal and trade dynamics in Morocco, contributing to the broader empirical literature on the twin deficits hypothesis in developing economies.
