Findings from the study show that the introduction of cell phones is associated with a decrease in price dispersion across grain markets. The effect is stronger for isolated markets and those with poor quality roads, as a higher percentage of these markets opt for cell phone coverage. A mathematical model is provided for estimating the impact of cell phones on traders’ behaviour.application/pdfenINFORMATION AND COMMUNICATION TECHNOLOGY (ICT)MARKET ACCESSNIGERMOBILE PHONESMOBILE TELECOMMUNICATION SERVICESAGRICULTURAL MARKETSINFORMATION NETWORKSKNOWLEDGE SHARINGE-AGRICULTUREPRICINGMATHEMATICAL MODELSSOUTH OF SAHARAPresentation
