IMF-全球化万岁：地缘政治冲击与国际贸易（英）-2023.10-21页_501kb

Introduction and Context

The paper addresses the question of whether globalization is truly dying, given recent geopolitical shocks like the COVID-19 pandemic and Russia's invasion of Ukraine, which have fueled protectionist policies. It challenges the notion of deglobalization, noting that despite these events, international trade has rebounded. The study uses a large dataset to analyze if geopolitical alignment affects trade, finding that conventional wisdom on economic integration may be overstated.

Methodology

Serhan Cevik employs an augmented gravity model based on data for 59,049 country pairs from 1948 to 2021, including variables like GDP, distance, cultural ties, trade agreements, and geopolitical alignment measured by UN voting patterns. The analysis uses Poisson Pseudo-Maximum Likelihood regression, instrumental variables, and impulse response functions to account for endogeneity and dynamic effects.

Key Findings

• Geopolitical alignment has contradictory effects on trade, positive for developed countries and negative for developing ones, but these effects are statistically insignificant. Economic significance diminishes when outliers are removed.
• Income levels in both origin and destination countries positively influence trade, while geographic distance negatively impacts trade flows due to higher costs.
• Cultural similarities, historical ties, and trade agreements (e.g., WTO/GATT membership and FTAs) enhance trade based on gravity model results.
• Trade globalization persists despite recent shocks, showing resilience over time; however, factors like rising inequality and supply chain changes require policy attention.

Conclusion

Globalization continues to integrate economies historically, with tentative evidence against systematic deglobalization. International trade depends more on income, distance, and trade agreements than geopolitics. Policymakers should focus on managing globalization's burdens through inclusive policies, avoiding protectionism to maintain global prosperity and resilience.
