Abstract

Advanced telecommunications are a key-technology, i.e., a cluster of innovations that are providing increasing returns to the rest of the economic system. Building on the new models of economic growth investment intensity in key technologies is likely to yield major positive effects on productivity growth. Empirical analysis on the determinants of labor productivity growth for twenty-four countries in the period 1979-86 confirms that investment intensity in advanced telecommunications had a strong positive impact, much stronger than the one exerted by general investment intensity.
