A property-tax agency collected 44% more revenue by handing the job to neighborhood chiefs who broke the law more, not less

the problem

A state tax agency's collectors didn't know who lived where, who owned what, or who could actually afford to pay -- and no amount of training could give them local knowledge they structurally lacked

background

what everyone would do

Train state agents harder, add enforcement pressure, or build better formal registries and assessment tools -- the standard response to a tax agency underperforming, all of which assume the agency's problem is a skill or resource gap rather than a fundamental lack of the local, granular information no amount of central-office training can substitute for.

what they saw

The researchers saw that state agents' underperformance wasn't about effort, persuasion skill, or enforcement authority -- a hybrid test where agents collected after a full local briefing from chiefs still didn't fully close the gap, and chiefs collected no more than agents when their targeting ability was deliberately neutralized. The real advantage was specifically informational: chiefs already knew which households could and would pay, letting them target visits efficiently in a way no amount of state-agent training could replicate without that same ground-level knowledge.

the move

In neighborhoods assigned to chief-led collection, city chiefs collected property tax directly instead of state agents, using their standing local knowledge of individual households rather than any new tool, technology, or enforcement authority the state agents lacked access to.

why it works

By delegating collection to people who already possessed the exact local knowledge the state agency lacked -- who owned what, who could pay, who genuinely couldn't -- Kananga captured a large compliance gain without having to build or fund any new formal information-gathering capacity, since the chiefs' knowledge already existed and cost nothing to access beyond the delegation itself. The hybrid experiment isolated why this worked: state agents given the same information but not the same local standing achieved a real but smaller compliance gain, showing the information itself did most of the work rather than any unique persuasive authority chiefs held as figures of local respect.

the payoff

Chief-led collection raised property tax compliance by 3.2 percentage points, a 44% increase in revenue over agent-led collection in the same period. Chiefs also collected roughly 2 percentage points more in bribes than state agents did -- payments made in lieu of the official tax rather than on top of it -- yet third-party verification found chiefs were actually more accurate at assessing property liability and more likely to correctly exempt elderly and disabled residents as Congolese law required, and the study found no evidence chief-led collection undermined citizens' trust in government or tax morale. A hybrid arm, where state agents collected after chiefs briefed them line-by-line on each household's ability to pay, achieved 2.2 percentage points higher compliance than agents alone but didn't fully close the gap to chief-only collection -- evidence the researchers interpret as showing chiefs succeeded mainly by using local information to target visits at high-payment-propensity households, not by being better at persuading people once visited.

where it breaks

This approach comes with a real, measured cost: chiefs extracted more informal bribes than state agents, and while this particular study found no measurable erosion of trust or tax morale, that finding may not generalize to every context, especially one where the informal actor's community standing is weaker or the bribes are more visibly extractive. It also depends on genuine alignment between the informal actor's interests and the formal institution's goals; delegating execution to a local elite who has no stake in the state succeeding, or who uses the position purely for personal extraction with none of the accuracy or fairness this study found, could produce all of the informal cost with none of the compliance gain.

what came after

Published in the American Economic Review in 2022, the study is cited in public-finance and development-economics research as direct evidence that delegating execution to whoever already holds the relevant local information -- even an informal actor operating partly outside the formal legal framework -- can outperform investing in a formal apparatus that structurally can't acquire that information on its own.
