How Non-Diamond Exports Respond to Exchange Rate Volatility in Botswana

Abstract

This paper estimates the impact of exchange rate volatility on non-diamond exports in Botswana using an Autoregressive Distributed Lag (ARDL) model. The model used quarterly data for the period 1995-2018, to estimate both the long and short run dynamics. The estimated results show that real GDP in the non-diamond sector, GDP growth of OECD countries, transport investment and water & electricity investment have a positive impact on non-diamond exports. While the lending interest rate, inflation differentials, exchange rate volatility and misalignment impact non-diamond exports negatively. The findings indicate that the coefficients with respect to the exchange rate volatility in both models are relatively low, suggesting that it has not had harmful impacts on non-diamond exports. This reflects the emphasis given to a stable and competitive exchange rate that will attract increased foreign demand which, as a result, could lead to export diversification. However, Botswana’s export structure is still undiversified, despite efforts made to diversify the sector. To achieve the national objectives of sustainable export and economic diversification, the policy should continue encouraging a stable and competitive exchange rate. Other policies intended to boost export growth should focus on: expanding the production base of the non-diamond sector, committing more investment in the transport sector, and improving water & electricity infrastructure.
