Summary of "South-South Regional Integration and Industrial Growth: The Case of the Andean Pact"

Core Content

This working paper by Dorsati H. Madani examines the impact of regional integration on industrial growth in three Andean countries: Bolivia, Colombia, and Ecuador. The study focuses on the Andean Pact, which was revived in 1991 through the Ica Declaration, and evaluates whether this regional arrangement had a significant effect on industrial growth compared to unilateral trade liberalization.

Main Findings

• Scale Effects: The study finds that cross-industry scale effects are small and negative in the three Andean countries. This suggests that regional integration does not significantly enhance industrial growth through scale economies.

• Heterogeneity in Scale Effects: There is significant variation in industry-level returns to scale, indicating that not all industries benefit equally from regional integration. This supports the idea that only certain industries may gain from scale effects.

• Import Variety and Growth: Increased variety of intermediate inputs from non-regional suppliers (rest of the world, ROW) has a small but positive and significant impact on growth in a few industries. This implies that trade liberalization may help industries access a broader range of inputs, which can enhance productivity.

• Regional Integration and Variety: The effect of regional variety on industrial growth is at best mixed. This suggests that the Andean Pact may not have provided substantial benefits in terms of variety of intermediate inputs compared to non-regional sources.

• Unilateral Liberalization: The study provides preliminary support for the idea that unilateral liberalization may have a more positive impact on industrial growth than regional integration, especially through the channel of increased import variety.

Key Information

Regional Integration and Industrial Growth

• The Andean Pact was established in 1969 and aimed at creating a common market in South America.
• By the late 1980s, the Pact had limited success in promoting internal trade due to factors like the debt crisis and the original agreement's concessionary measures.
• The Pact's revival in 1991 led to increased trade with regional partners, but this did not translate into substantial industrial growth gains through scale effects.

Methodology and Data

• The study uses 3-digit ISIC industry-level data over a 16 to 23-year period.
• It incorporates two main mechanisms: economies of scale and import variety.
• Three measures of integration are used:
  • Import Variety Measures: Based on the number of suppliers and goods variety.
  • First Date of Imports: Tracks the introduction of new varieties of intermediate inputs from different suppliers.
  • Dummy Variable: Captures the 1991 renewal of the Andean Pact.

Theoretical Framework

• The theoretical model assumes a constant returns to scale production function and uses a growth accounting approach.
• The study estimates the impact of regional integration on output growth using an expanded version of the growth equation, incorporating both regional and non-regional inputs.

Implications

• The findings suggest that unilateral liberalization may be more effective in promoting industrial growth than regional integration.
• Scale effects from regional integration are limited and do not provide large or widespread gains.
• The import variety from non-regional suppliers plays a more significant role in industrial growth than regional variety.
• The results are important as they provide empirical evidence from developing economies, contrasting with previous studies that focused mainly on developed countries.

Conclusion

The paper concludes that the revival of the Andean Pact did not significantly boost industrial growth in the three countries through scale effects. Instead, the benefits of trade liberalization, particularly in terms of increased import variety, may be more impactful. The study emphasizes the need for a nuanced understanding of how different industries respond to regional integration and trade liberalization, highlighting the importance of considering the specific characteristics of each industry.
