Here is his excellent column on decentralized provincial health care provision in Canada. Excerpt:

By fixing the maximum federal contribution, block grants offer Canada’s provincial and territorial governments far better incentives to reduce the cost and improve the quality of the medical services they purchase. When costs rise, the provinces that run the programs are forced to pay 100 percent of the added costs at the margin, unlike in the U.S., where state governments pay an average of 43 cents at the margin for every dollar of added Medicaid expense.

Decentralized administration gives provinces the flexibility and the accountability to design their programs according to their needs and particular local challenges, rather than federal “one-size-fits-none” imposition. It also creates opportunities for innovation. By sharing notes, provinces and territories learn from one another and improve their Medicare programs.

Canada has been using block grants for 35 years. After several years of ruinously high growth in Medicare expenses during the 1970s, their federal government abandoned a 50-50 cost-sharing plan in 1977. Through the Canada Health Transfer program, which gives states some money directly and some through tax-shifting agreements, Canadian provinces and territories receive equal per capita aid, regardless of actual health care expenditure.
