Paper Abstract We study how the perceived source of environmental information—government or non-government—affects consumers’ beliefs and demand for air quality forecasts in developing economies. In a randomized experiment in Lahore, Pakistan, we provide identical day-ahead SMS forecasts, varying only the attributed source. Subjects exhibit high willingness-to-pay regardless of source but perceive government forecasts as less accurate, implying limited demand for accuracy. Donation games reveal that subjects prefer their assigned source and value service attributes beyond accuracy, such as reliability. Source exposure—not just content—shapes consumers’ beliefs and preferences, with implications for welfare-enhancing access to environmental information in low-capacity settings.
