In 1997, gross state product (GSP) per non-farm payroll employee in Mississippi was 30% lower than in Florida. Few analysts back then, if asked, would have projected Mississippi to match Florida fifteen years later. In 2012, however, by that measure of labor productivity the magnolia state was one percent ahead of the sunshine state. More realistically, given how hard it is to measure value added, the two states were essentially the same. Over the 15 years, output per worker rose 76% in Mississippi, more than three times Florida’s 22%.
