With ELE, a state's Medicaid and/or CHIP program can rely on another agency's eligibility findings to qualify children for public coverage. Using 2007 to 2011 quarterly enrollment data, we estimate difference-in-difference equations with quarter and state fixed effects to measure the effect of ELE on enrollment. The estimated impacts of ELE on Medicaid enrollment were consistently positive across model specifications, ranging between 4.0 and 7.3 percent. The analysis also finds that ELE increased Medicaid/CHIP enrollment. Our results imply that ELE has been an effective way for states to increase new enrollment or improve retention among eligible children.
