摘要：This paper examines the sources of productivity growth for the U.S. telecommunications industry from 1935 to 1987. These years encompass both the pre- and post-AT&T divestiture periods. We formulate a structural model that accounts for both changes in the cost and the demand side of the industry. We measure the contributions of aggregate demand, information intensity of the economy, price-cost margins, relative factor prices, direct and indirect effects of technological progress, and R&D inves...

Equipment capital and firm R&D in the same product as a plant are consistently skill biased, while structures are biased against skill. Furthermore, general firm and industry...
