📍 What this study asks

This research tests whether expanding formal taxation in a fragile state prompts citizens to demand a greater voice in government. The central claim is that bringing citizens into the tax base generates a measurable "participation dividend."

📊 How the tax campaign was tested

• A field experiment randomized a property tax collection campaign across 356 neighborhoods in a large Congolese city.
• For most residents, the campaign represented the first time the state registered them or asked them to pay formal taxes.

📈 Key results

• Property tax compliance rose from 0.1% in control neighborhoods to 11.6% in treated neighborhoods.
• Political participation increased by about 5 percentage points (a 31% change): residents in taxed neighborhoods were more likely to attend government-hosted town halls and to submit evaluations of government performance.
• Participatory activity carried tangible costs: the average citizen incurred costs equal to their daily household income to participate, and treated citizens spent 43% more than control residents.
• Treated citizens also updated perceptions of the provincial government positively—reporting higher perceived revenue, lower perceived leakage, and a stronger sense that the government is responsible for providing public goods.

💡 Why this matters

These findings indicate that broadening the tax base in a weak state can stimulate citizens to engage more with government institutions. The observed "participation dividend" links contemporary evidence to historical narratives about the rise of inclusive governance in early modern Europe and reinforces common donor rationales for supporting tax programs in fragile states.
