Abstract Governments around the world are investing in technologies that allow citizens to participate in the coproduction of public services by providing monitoring and feedback, but there is little evidence about how these initiatives affect the quality of public services. We implemented a large-scale field experiment that involved organizing 50 citizen reporters in each of 100 neighborhoods across Kampala, Uganda, to provide weekly reports to the municipal government about the delivery of solid waste services via an SMS-messaging platform, resulting in 23,856 reports during the 9-month study period. Citizen reporting did not reduce informal waste accumulation as targeted, which would indicate improvements to formal services. Using our observations as participants in the development and deployment of the reporting platform and interviews with staff at the government agency receiving the citizen reports, we show how the public generated inconsistent information that did not fit existing decision-making processes. We generalize lessons from this field experiment by explaining how coproduction involving information sharing through information and communication technologies is likely to affect public services based on the alignment of citizen-produced data with the information problems managers face; the search costs of detecting public services failures; the quality of citizen-produced data; and the operating costs of citizen-reporting platforms.

Improving urban air quality is a pressing challenge in the Global South. A key source of air pollution is the informal burning of household waste. Reducing informal burning requires governments to develop formal systems for waste disposal and for residents to adopt new disposal behaviors. Using a randomized experiment, we show that social competitions between pairs of neighborhoods in Nansana municipality, Uganda, galvanized leadership and inspired collective action to reduce informal burning. All 44 neighborhoods in the study received a public health campaign, while 22 treated neighborhoods were paired and competed to reduce waste burning over an 8-mo period. Treated neighborhoods showed a 24 percent reduction (95% CI: 11 to 35 percent) in waste burning relative to control neighborhoods at the end of the competition period. There is no evidence that treated neighborhoods experienced a rebound in waste burning several months after the competitions. Community leaders reported greater effort in coordinating residents and more pride in their neighborhood when assigned to the competition treatment. These results suggest that creating focal points for leadership and collective action can be an effective and low-cost strategy to address policy problems that require broad participation and costly behavior change.
