A relatively slow rate of growth in U.S. health-care spending over the last four years has led to some hope that broad-based reforms by the industry are having an impact, but a new study found that three-quarters of the decline can be attributed to recent economic turns. The researchers behind the study, including Thomas Getzen of Temple's Fox School of Business, analyzed national health-care spending from 1965 through 2011 and concluded that inflation and gross domestic product adjusted for inflation accounted for most of the fluctuation in the growth rates of health-care spending.
