Summary of "More Than Copper: Toward the Diversification and Stabilization of Zambian Exports"

Core Content

This paper investigates the export patterns of Zambia from 1999 to 2011, utilizing a detailed transaction-level trade dataset. The study highlights the high concentration of Zambian exports in mining products, particularly copper and cobalt, which account for over 80% of formal exports in value terms. The analysis also identifies a significant degree of firm and product churn, indicating that export activities are highly unstable and short-lived.

Main Viewpoints

• Export Concentration: Zambia's exports are exceptionally concentrated in mining products, with copper and related products dominating the export value. This concentration has increased over the past decade, largely due to rising global commodity prices.
• Export Churning: Zambian export firms exhibit high levels of entry and exit, with an average exit rate of 41% and an average spell duration of 1.9 years. This suggests that the export sector is dynamic but also unstable.
• Regional Trade Dynamics: While the majority of exports are directed to European markets (53% of total export value), there has been a notable shift towards intra-African trade, especially within Sub-Saharan Africa (SSA), which now accounts for 80% of non-traditional exports by 2011.
• Non-traditional Exports: Despite the dominance of traditional exports, non-traditional exports have grown in terms of transaction numbers, representing 64% of all exports. However, their value remains relatively low, indicating challenges in scaling up these sectors.
• Exchange Rate Volatility: The study finds that exchange rate fluctuations significantly contribute to the instability of Zambian exports. A 10% increase in annualized exchange rate volatility is associated with a 4.7% increase in the hazard rate of export spells.
• Imported Inputs: Firms that rely heavily on imported inputs face greater instability in their export activities. The paper suggests that the intensity of imported inputs is a key determinant of export survival, with a 10% increase in intermediate imports linked to a 0.3–0.4% increase in export hazard rates.
• Policy Implications: The research underscores the need for policy reforms to stabilize Zambian exports, particularly by improving access to imported inputs, easing foreign exchange transactions, simplifying export and certification requirements, and increasing the predictability of the trade regime.

Key Information

• Data Sources: The study uses Zambian customs data from the ASYCUDA system, covering 1.37 million trade transactions, of which 99,000 are exports.
• Export Firms: The number of formal exporting firms in Zambia increased from 516 in 2000 to 1,754 in 2011, indicating growth in the export sector.
• Product Composition: Mining products (metals and minerals) account for 82% of export value, while non-traditional sectors like foodstuffs, vegetables, and textiles make up only 4.5%, 3.3%, and 2.3%, respectively.
• Re-exports: Re-exports constitute a quarter of all export transactions, and their exclusion would increase the dominance of traditional exports. For example, the value share of metals and minerals in Zambian-sourced exports is estimated at 92%.
• Survival Analysis: Using a Cox proportional hazard model, the study identifies exchange rate volatility and high reliance on imported inputs as major destabilizing factors. Regional trade groupings like COMESA, SADC, SACU, and the EU do not appear to have a stabilizing effect.
• Qualitative Insights: Interviews with Zambian exporters reveal that many lack a formal export strategy and rely on ad hoc methods. There are also challenges related to exchange rate instability, difficulty in importing inputs, and inefficiencies in financial, electricity, and infrastructure services.

Conclusion

The paper concludes that Zambia's export sector remains highly concentrated and unstable, with a strong dependence on copper and related products. To unlock the country's full export potential, policies should focus on improving access to imported inputs, reducing exchange rate volatility, and simplifying trade procedures. These measures could help promote the growth and stability of non-traditional exports, which are essential for economic diversification and resilience.
