What Does Health Reform Mean for the Healthcare Industry? Evidence from the Massachusetts Special Senate Election
AbstractThe recent reform of the U.S. health care system has been described both as a boon and a death blow for the healthcare industry and for private insurers in particular. We exploit the surprise election of Republican Scott Brown to the U.S. Senate, which dealt a serious blow to the prospects for reform by depriving Democrats of their 60-vote “filibuster-proof” majority, to evaluate the market's assessment of Health Reform’s impact on the health care industry. We find that Scott Brown’s election was associated with an abnormal return of 2.2 percent for a typical dollar invested in health care stocks and an abnormal return of 6.3 percent for a typical dollar invested in managed care firms. A typical dollar invested in the pharmaceutical sector experienced abnormal returns of 2.9 percent, while investments in healthcare facilities (including hospitals) experienced abnormal losses of 3.4 percent. Analysis of firms participating in government programs show that firms involved with Medicare Advantage experienced gains while those involved with Medicaid Managed Care experienced losses due to the election.
