Part of the "Economics USA" series. In the 1970s, businesses struggled with rising energy costs, newly imposed environmental regulations, and inflation that contributed to the slowing of productivity. By 1980, a new group of economists called "supply-siders" were calling for government deregulation to spur productivity, amidst great objections from Democrats and some economic experts. Some thought that productivity was at an end, but government-supported technological innovation spurred productivity to new heights. These stories highlight the factors that affect productivity and how government programs have both helped and hindered growth.
