Why Healthcare Markets Are Different: Market Failures, Moral Hazard, and the Economics of Life and Death

It is August 1994. You are sitting in what remains of the Ministry of Health building in Kigali. Three months ago, somewhere between 500,000 and 800,000 Rwandans were killed in 100 days. The country's health infrastructure, never robust to begin with, has been gutted: physicians fled or were murdered, clinics were looted, supply chains collapsed, and the population that survived is traumatized, displaced, and largely destitute.

You have no functioning insurance system. The few health facilities still operating charge fees at the point of service, which means the people who need care most, the poorest and sickest, simply do not go. A cholera outbreak is spreading through refugee camps along the Zaire border. Child mortality is catastrophic.

Two advisors sit across from you, and they disagree sharply.

The first is an economist from a Washington-based development institution. His argument is clean and familiar: markets allocate resources efficiently. If you allow private clinics to open, charge competitive prices, and let supply meet demand, the system will rebuild itself without requiring the government, which has no money and no capacity, to manage anything. Price signals will direct resources where they are needed. Subsidize only the very poorest through targeted vouchers if you must, but do not distort the market with mandatory schemes.

The second advisor is a public health specialist who has spent a decade in sub-Saharan Africa. She is less tidy but more urgent. She tells you that the market-only approach has been the default across the continent for years, and the results are not ambiguous. User fees introduced across Africa in the 1980s and 1990s under structural adjustment programs caused dramatic drops in clinic attendance, particularly among women and children. Markets do not rebuild health systems after genocides. She wants you to design a mandatory community-based insurance scheme, pooling risk across rich and poor, healthy and sick, with premiums set by household income.

The economist raises a legitimate objection: mandatory insurance creates moral hazard. If people are insured, they will overuse services, driving up costs and potentially crowding out the genuinely sick. You will distort incentives and create a fiscal time bomb.

You have to decide. Do you let the market rebuild Rwanda's health system, or do you impose a mandatory community insurance scheme over the objections of economists who warn it will distort behavior?

Sit with that choice for a moment. Both options have real logic behind them. The tension you feel is not accidental.
