Since 1991, the Ministry of Agriculture and Rural Development (MADER) of Mozambique, through the Agricultural Market Information System (SIMA) has collected, processed and disseminated weekly information regarding prices of basic commodities at different market transaction levels. This information has been used by different actors in the market, including producers, traders, NGOs, consultants, and policy makers. SIMA has made efforts to serve multiple users, from the private and public sectors, using a variety of means of communication, thereby contributing to the development of agricultural markets. However, in a time of budget constraints, there is one important question: What is the value of investing in public market information as is currently done in Mozambique? This is discussed in this paper.
