Mobile Phones and Mozambique Farmers: Less Asymmetric Information and More Trader Competition?

We investigate the impact of search costs of farmers and traders on prices, by measuring to what extent the introduction of mobile phones in Mozambique has affected the margin between recorded maize producer prices and retail market prices, and by exploring who benefits from possible margin changes. Estimations are based on weekly producer and retail market prices of white maize grain, from July 1997 to December 2009, for 15 major producer markets in Mozambique. We find a margin increase varying from 4.5% to 9.6%, supporting a bias of benefits towards traders. Hence, not less asymmetric information and more trader competition, but rather the reverse. Estimation results are robust for non-random rollout of the mobile phone network and various other threats. Impacts can be traced towards improved information on terminal market prices and are also significantly correlated with network density. Household survey data yield a mostly insignificant impact for farmers, consistent with the key result of this study. Several farmer characteristics are in line with lower farmer benefits.
