Abstract: | The health spending slowdown associated with the managed care revolution in the 1990s suggests that managed care may have been successful in controlling health care spending. I exploit the passage of state regulation during the “managed care backlash” as well as geographic variation in managed care intensity to measure the impact of managed care on spending. I find that restricting managed care causes a large and significant increase in hospital spending, which cannot be explained by changes in hospital market concentration, other regulatory activity, and multiple other possible explanations. I also do not find effects of the backlash on mortality. |
