Q: Are You Sure That CBO’s Current Estimates of the Labor Market Effects of the ACA Are Accurate?

A: No, we are not sure that our current estimates are accurate, because our estimates are always uncertain. As we emphasized in the report: “CBO’s estimate of the ACA’s impact on labor markets is subject to substantial uncertainty, which arises in part because many of the ACA’s provisions have never been implemented on such a broad scale and in part because available estimates of many key responses vary considerably. CBO seeks to provide estimates that lie in the middle of the distribution of possible outcomes, but the actual effects could differ notably from those estimates.”
