By 'economic growth' economists mean, in the first place, annual increases in the nation's total output of goods and services -- its national product. Maintaining rapid economic growth depends increasingly on productivity gains, particularly in the service sector. Economic growth and the productivity are impacted by individual enterprises, industrial sectors and the wider economy. The standard of living of a country is profoundly effected by economic growth and productivity. One of the key questions within the debate on economic growth and productivity is the effect of information technology on the system. This new book presents leading edge research on this exciting topic.
