A central question in the debate over privatized Medicare is whether increased government payments to private Medicare Advantage (MA) plans generate lower premiums for consumers or higher profits for producers. Using difference-in-differences variation brought about by a sharp legislative...

We examine the effect of New York City's universal pre-kindergarten program (UPK) on the health and utilization of children enrolled in Medicaid using a difference-in-regression- discontinuities design. We find that UPK increases the probability that a child is diagnosed with asthma or with...
