Abstract
This paper investigates the effects of connectivity charges (communication costs) on bilateral exports in Sub Saharan Africa (SSA). Data from 19 exporter countries was used together with communication costs data in a gravity model of trade setup. The export data derive from the IMF Direction of Trade and the COMTRADE databases, while the communication cost data was collated from a variety of sources including direct contact with service providers. We find that communication cost is an important factor in bilateral trade in the region. Communications have a significant negative effect on export intensity. The study also reveals that countries with high communication costs generally have lower export intensity than countries with low communication costs. The results suggest that investment in ICT infrastructure that brings down international communication costs will have a positive effect on regional trade in the long run.

Notes
- 1.
Whether increased intra African trade and trade openness indeed have positive effects on growth in Sub-Saharan Africa is not addressed in the present paper. This remains an important avenue for future research.

As mentioned in the previous section, only SSA countries are included in the analysis, in order to avoid the confounding effects of strong trade ties to former colonial countries. The focus is on intra-African trade.

We tested the results using PPP Dollar GDP figures and found similar results. We show the results obtained using current dollar figures because these were more readily available in a consistent format than the PPP Dollar GDP figures.
