Living-Donor Kidney Transplants

Question A:

There is draft legislation in Congress to increase the supply of human kidneys by encouraging donations to strangers: https://www.congress.gov/bill/119th-congress/house-bill/2687

It is summarized here: https://www.hawaiibusiness.com/bipartisan-bill-aims-to-prevent-kidney-deaths-by-compensating-donors/

Existing matching markets for kidney exchange have extended the lives of thousands of Americans with kidney disease.

Responses weighted by each expert's confidence

Question B:

A one-time $50,000 tax credit for kidney donation to strangers (with the transplants allocated at zero cost to recipients on the basis of waiting times) would save thousands of lives and pay for itself through a reduction in the cost of providing medical care to people suffering from renal failure.

Responses weighted by each expert's confidence

Question C:

Allowing hospitals to pay people for kidney donation to strangers would be at least as effective at saving lives and more cost effective than a tax credit.

Responses weighted by each expert's confidence

Even if it were to "pay for itself," one should tread very carefully given ethical questions. What's next: a market for lungs, bone marrow, corneas? What if (poor) people are willing to "supply" their organs at an even lower price? Should we totally free up "market forces"? Grim.

Since the proposal states that the tax credit will become a net payment to donors with insufficient tax liability it is equivalent to a 50K payment. So why not just send a government check?

No idea about the specific numbers. This is what Al Roth calls a "repugnant transaction". Non-economists resist market solutions.

This is difficult, becase there is a need for balance. The purchase of an organ is a "repugnant transaction". The efficiency gains are obvious, but the market should be excluded from some realms. The tax credit + queuing mechanism help.

I am confident providing incentives for donations is part of the solution and can help save lives. I have not seen the calculations showing it "pays for itself", but that seems possible (even if it is not the right metric or threshold for evaluation).

Given morality and equity issues, we need a centralized market. Leaving it to hospitals would not achieve this. Prices could vary and this would make it harder for people to accept the idea of monetary payments. Also the 50K is structured to be equivalent to a direct payment.

As as purely economic question, yes, this is more efficient. There are issues around governance, ethics, and the ultimate source of funding that the question does not specify. In general, the cost savings from more kidney transplants that obviate dialysis are huge.

Without the 50K subsidy from taxpayers, it is possible that fewer kidney transplants from strangers would occur. Allocations to receivers would also change, because hospitals would probably favor patients able to pay at least part of the added cost.

It would also raise donations and save lives. But a cost comparison is difficult without more precision, e.g. price may not be the same. The tax credit also has a delayed benefit built in, which may be considered a feature.
