This US survey examines:  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/; (a) Existing matching markets for kidney exchange have extended the lives of thousands of Americans with kidney disease; (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; (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
