Information and communications technology: The Role of ICT in the World Economy

ICT is considered one of the three major technological breakthroughs of the modern era (see Edquist and Henrekson 2007), the others being steam power and electricity. ICT includes some of the wider information technology innovations and applications, and their commercialization and transfer have been quite rapid. These enhance the communication of more accurate and value-added information to workers, managers, and consumers, thus reducing uncertainty and timeuse in conductingmany types of businesses.

There has been great interestamong researchers in investigating how some countries were able to take advantage of ICT to accelerate their rates of growth and productivity. In these studies one examines the contribution of IT investment to economic growth and finds that the returns on IT investment are significantly positive. In the transitional countries of Central and Eastern Europe (CEE), one observes a chronic underinvestment in telecommunications infrastructure. The result suggests that improving investment may ultimately improve the channel between aggregate investment and growth economywide (see alsoZhu 1996;Madden and Savage 1998).

Return on IT differs by the country’s development level.Results fromintercountry studies relating IT and non-IT inputs to gross domestic product (GDP) over time suggest that for developed countries, returns fromITcapital investments are positive, while returns from non-IT capital investments are not commensurate with relative factor shares. The situation is reversed for developing countries, where

The impacts of IT investment on economic growth in a cross section of countries shows that the relative contribution of IT toGDPgrowth in developing counties between 1980 and 1995was less than 2 percent, compared tomore than 10 percent in developed countries (see Dewan and Kraemer 2000; Pohjola 2001).
