Does the Use of Mobile Phones by Smallholder Maize Farmers Affect Productivity in Ghana?

This study evaluates the effects of mobile technology on productivity and the channels of transmission of these effects. Using propensity score matching procedures, the results show that mobile phone ownership and use significantly improves agricultural productivity. Specifically, the mobile phone improves the productivity of user-farmers by at least 261.20 kg/ha per production season. Further, we find that phone ownership and use impacts productivity more than phone use only. The identified channels of effect are extension services, adoption of modern technology and market participation. These results have key policy implications for Ghana and developing economies at large.
