Price-information systems established by national governments, for instance with respect to West African cereals markets, are of varying data quality and timeliness, rarely include information from markets in neighbouring countries and are not typically available to the private sector in user-friendly, market-supporting ways that alleviate inequality of access to price information. Smallholders failing to access publicly available information on market prices typically establish contacts through mobile phones for undifferentiated low-quality commodities (USAID, 2011). However, new technologies, in particular the increasing coverage and decreasing cost of mobile phones25, contribute significantly in overcoming those constraints, especially in more remote markets and those without paved roads.
