Over the last decade, the U.S. Medicare program has added new billing codes to enhance the financial rewards for Chronic Care Management and Transitional Care Management. We show that the take-up of these new billing codes is gradual and exhibits substantial variations across markets and...

Can the expansion of Medicaid, a means-tested health and long-term care insurance, be slowed down by incentivising the purchase of private long-term care insurance (LTCI)? We study the implementation of the long-term care insurance partnership (LTCIP) program, a joint federal and state-level...
