The World Bank Pilot Study for Crowd-Sourced Price Data Collection through Mobile Phones combined the need for high-frequency data, recent developments in information and communication technologies, and power of crowd. Crowd-sourced data are data collected and reported by the user community using information and communication technologies. The objective of the pilot was to study the feasibility of crowd-sourced price data collection. Non-professional price collectors used personal computers and mobile phones for collecting data and entering it in a multilingual web microsite developed for the pilot. Price data was collected for thirty tightly specified food commodity items on a monthly basis for approximately six months in eight pilot countries. Non-professional price collectors received compensation in the form of airtime rewards.
