When free water connections make economic sense
Charging for public infrastructure can seem like an unavoidable compromise: fees help cover costs but exclude households with little money. A study of a new piped drinking water network in rural Bangladesh finds that this logic can run backwards. Researchers elicited households’ willingness to pay, with truthful answers encouraged by a real opportunity to connect, and combined those responses with project cost data. The price that minimized cost per connected household was zero.
The explanation is economies of scale: attracting more connections spreads network costs widely enough to outweigh the revenue forgone by waiving fees. This does not mean that free connections make infrastructure costless. It means that maximizing cost-effectiveness need not conflict with expanding access. The authors identify two ingredients behind that result: substantial economies of scale and demand that responds strongly to prices near zero.

Talk about a paper in public without overstating it: yours, one you are asked to comment on, or one you write about as a journalist.
- Your paper: a draft release for your press office, the questions journalists will ask with what the paper lets you answer, the likely misreadings, a lay summary and a short thread.
- Asked to comment: what the paper shows and does not, its strengths and weaknesses with their passages, and what would settle its main claim.
- Writing about it as a journalist: reporting angles, the wording to check before publication, and the questions to ask the authors.
- For everyone: findings with their passages checked word for word, the novelty set against the closest earlier papers, a hype check, figures with their credit, and researchers for an outside view who have not signed with the authors.
