Summary of The Global Impact of the Systemic Economies and MENA Business Cycles

Core Content

This paper examines the spillover effects of macroeconomic shocks from three systemic economies (China, the Euro Area, and the United States) to the Middle East and North Africa (MENA) region, as well as the outward spillovers from the Gulf Cooperation Council (GCC) countries and MENA oil exporters to the rest of the world. The analysis is conducted using a Global Vector Autoregression (GVAR) model, which includes 38 country/region-specific models covering the period 1979Q2 to 2011Q2.

The GVAR model accounts for spillovers through trade, financial, and commodity price linkages, and is used to estimate the size and speed of shock transmission across economies. The study also investigates how changes in global trade patterns, particularly the rise of China, have influenced the international business cycle and its impact on the MENA region.

Main Points

1. Inward Spillovers from Systemic Economies

• MENA countries are more sensitive to China's GDP shocks than to those from the Euro Area or the United States, consistent with evolving trade patterns and China's growing role in the global economy.
• U.S. GDP shocks have a large impact on typical MENA economies, though this impact has remained relatively stable since the mid-1980s.
• Euro Area GDP shocks also have a significant effect, but to a lesser extent than China.

2. Outward Spillovers from the MENA Region

• GCC and MENA oil exporters have stronger geographical spillovers, but their influence also extends globally, especially due to their role in oil production and export.
• The GVAR model is used to capture the interconnectedness of global economies and assess how shocks in one region propagate to others.

3. Methodology

• The model includes 38 country/region-specific VARX models*, which are solved in a global framework.
• Domestic variables include real GDP, inflation, short-term and long-term interest rates, and real equity prices.
• Foreign variables are calculated as weighted averages of domestic variables, using bilateral trade data as weights.
• Global variables include oil prices and global oil production, which are treated as weakly exogenous in most models but endogenous in the GCC block.

4. Trade Weights

• Trade weights are based on fixed averages from two periods: 1986–1988 and 2006–2008.
• The MENA region has limited global competitiveness, with a small share of non-fuel exports and low inter-regional trade.
• China's growing influence is reflected in the increased trade weights with MENA countries, especially from 2006–2008.

5. Model Advancements

• The paper extends the geographical coverage of the GVAR model to include the MENA region and other major oil exporters.
• It introduces a measure of global oil production to account for supply-side factors in the global oil market.
• It highlights the emerging role of China in global macroeconomic linkages and its increasing impact on the international business cycle.

Key Findings

• China's GDP shocks have a greater impact on the MENA region compared to shocks from the Euro Area or the U.S., due to increased trade integration and the global significance of China's economy.
• Outward spillovers from the GCC and MENA oil exporters are strongest in their immediate geographical proximity, but also have global implications, particularly for oil-dependent economies.
• The U.S. remains a key driver of global economic conditions, with its GDP shocks having a significant and consistent impact on MENA economies.
• Structural breaks and weak exogeneity are tested to ensure the robustness of the model, and country-specific estimates are used to analyze the dynamics of shock transmission.

Conclusion

The study underscores the increasing interconnectedness of the global economy and the important role of the MENA region in both receiving and transmitting macroeconomic shocks. It also highlights the growing influence of China on global business cycles and the importance of oil prices and production in shaping economic outcomes in the MENA region and beyond. The GVAR framework provides a comprehensive tool for analyzing these spillovers and understanding the complex interactions between global and regional economies.
