First, state Chambers are more likely to come out in favor of the expansion when health care providers hold leadership positions. Only 25 percent of state Chambers without a health provider on their board of directors supported the Medicaid expansion, while 55 percent of Chambers with a health provider on their boards did so. This makes sense since hospitals and other health providers stand to do more business if formerly uninsured patients start paying for care through Medicaid. What is more, health providers face losses in states that do not accept the new Medicaid funds, because the Affordable Care Act cuts back on previous payments to hospitals that provide uncompensated care to uninsured patients.
More precisely, state Chambers are especially likely to come out in favor of Medicaid expansion when providers serve on boards and a relatively larger pool of new enrollees would be covered. In states where providers do not serve on Chamber boards, moving from the smallest to the largest forecasted change in the new enrollee pools has no effect on the likelihood that the Chamber will endorse expansion. But in states where health providers do sit on boards, the probability of Chamber endorsement skyrockets as the potential new enrollee pool grows. In interviews, Chamber members told me that decisions to support expansion have not been ideological, but rather driven by the worries of providers, insurers, and employers about having to pay the cost of uncompensated health care.
A final explanatory factor is whether or not state Chambers have a dedicated staff person for health policy issues. Chambers with such policy expertise were more likely to support the expansion. According to Chamber leaders, having a trusted health policy expert who can make the economic case for expansion especially helped to persuade business leaders outside the health care industry.
My initial findings have implications for how we think about the future of the Affordable Care Act. As time passes, growing state-level business support for Medicaid expansion – and for the federal subsidies that make that expansion possible – may become a central force sustaining the implementation of health reform, especially in otherwise very conservative states. These results suggest that health reform advocates seeking business support for Medicaid would do well to focus on the economic case for expansion, to ensure that health providers’ voices are heard within their respective associations, and to provide credible sources of health policy expertise to employers still making up their minds.
Overall, growing business support for this central part of the Affordable Care Act bodes well for health reform. When the U.S. created Social Security and Medicare, businesses largely climbed on board during implementation, even if they opposed the legislation. For the Affordable Care Act, it may be déjà vu.
