The Yemen Joint Market Monitoring Initiative (JMMI) was launched by REACH in collaboration with the Water,
Sanitation, and Hygiene (WASH) Cluster and the Cash and Market Working Group (CMWG) to support humanitarian actors with the harmonization of price monitoring among all cash actors in Yemen.
The JMMI is a monthly survey of market systems. The basket of goods assessed includes 10 non-food items (NFIs), such as fuel, water, and hygiene products, reflecting the programmatic areas of the WASH Cluster. The JMMI tracks all components of the WASH and Food Survival Minimum Expenditure Basket (SMEB) as well as other food and non-food items. In addition to price monitoring, the JMMI includes indicators of market fuctionality, such as questions to infere the supply chain, vendors' constraints and ability to meet demands
Data was collected through interviews with vendor key informants (KIs), selected by partner organisations from markets of various sizes in both urban and rural areas. A minimum of three price quotations, per district, must be obtained. Following data collection, REACH compiles, cleans and analyzes all data, through detailed followups with partners. REACH uses medians to aggregate findings to district, governorate, de-facto authorities (DFA), internationally recognized government (IRG), and national level. It also calculates SMEB prices. Findings are indicative for the assessed locations and time frame in which the data was collected. Please refer to page 12 for additional methodological details.
