(Thispassage is excerpted from material published in 1997)
    Whereas United States
economic productivitygrew at an annual rate of 3 percent from 1945 to 1965, it has grown at anannual rate of only about 1 percent since the early 1970’s. What might bepreventing higher productivity growth? Clearly, the manufacturing sector of theeconomy cannot be blamed. Since 1980, productivity improvements in manufacturinghave moved the United Statesfrom a position of acute decline in manufacturing to one of world prominence.Manufacturing, however, constitutes a relatively small proportion of theeconomy. In 1992, goods-producing businesses employed only 19.1 percent ofAmerican workers, whereas service-producing businesses employed 70 percent. Althoughthe service sector has grown since the late 1970’s, its productivity growth hasdeclined. Several explanations have been offered for this declined and for the discrepancy in productivitygrowth between the manufacturing and service sectors. One is that traditionalmeasures fail to reflect service-sector productivity growth because it has beenconcentrated in improved quality of services. Yet traditional measures of manufacturingproductivity have shown significant increases despite the under measurement ofquality, whereas service productivity has continued to stagnate. Others argue thatsince the 1970’s, manufacturing workers, faced with strong foreign competition,have learned to work more efficiently in order to keep their jobs in the United States,but service workers, who are typically under less global competitive pressure, havenot. However, the pressure on manufacturing workers in the United States to work more efficientlyhas generally been overstated, often for political reasons. In fact, while somemanufacturing jobs have been lost due to foreign competition, many more havebeen lost simply because of slow growth in demand for manufactured goods.       Yet another explanation blames thefederal budget deficit: if it were lower, interest rate would be lower too,thereby increasing investment in the development of new technologies, whichwould spur productivity growth in the service sector. There is, however, nodearth of technological resources, rather, managers in the service sector failto take advantage of widely available skills and machines. High productivity growthlevels attained by leading edge service companies indicate that service sectormanagers who wisely implement available technology and choose skillful workerscan significantly improve their companies’ productivity. The culprits forservice-sector productivity stagnation are the forces－such as corporate takeovers andunnecessary governmental regulation－that distract managers from the task ofmaking optimal use of available resources.
