Abstract:

This paper establishes the determinants of the export durability of agriculture products in Zambia with specific attention to maize, sugar, cotton, and tobacco between 1996 and 2019. We find that approximately 39% of Zambia’s agricultural products were exported beyond the first year of trading and less than 10% lasted up to 6 years of trading. The mean and median duration of exporting agricultural products in Zambia was 1.7 years and 1 year, respectively. Among the products, maize had the highest export duration after the first year of trading, followed by sugar, tobacco, and cotton. Results of the discrete-time logit and probit models with random effects revealed that the duration of total agricultural products was significantly impacted by common colony, contiguity, partner’s gross domestic product (GDP), Zambia’s GDP, initial exports, and total exports. Of these factors, colonial history and Zambia’s GDP reduced export duration, while contiguity, partner’s GDP, initial exports, and total exports increased the durability of exports in Zambia. The effect of Zambia’s GDP was uniform across all individual agricultural products. Total exports also significantly impacted all other agriculture products in a similar manner except for maize. Export durability for cotton was significantly impacted by the Regional Trade Agreements (RTAs), while the export durability of tobacco was significantly impacted by distance, contiguity, and partner’s GDP. To increase the duration of agriculture exports, we propose the exporting of finished agriculture products (and not just raw materials), which have a higher market value and duration probability. Farmers also need support with export subsidies, increased foreign market access (especially to economies with higher buying power), and negotiated favorable trade terms in the region and around the globe.
