Note: Table shows reduced form and instrumental variable estimates for inpatient outcomes. For each outcome, the first column shows estimates of control-treatment differences from estimating the pooled version of the reduced form specification in Equation (1) and estimates of the impact of Medicaid managed care from estimating our instrumental variable specification, pooling over the entire post-period. The second column shows reduced form and instrumental variable estimates, when the post-period is broken into two separate periods, 2007–2008 and 2009–2010. In the second and fourth columns we estimate the IV coefficient using the two separate treatment post interaction terms as instruments. We control for service area by quarter fixed effects. Standard errors are clustered at the county level. For more details, see Section III. (N = 643, 751 beneficiary-quarters.)
