This article argues that an effective way to analyse the macroeconomic effects of business-to-business electronic commerce is to regard it as a decline in the cost of information to producers. Calculations based on input-output tables and the IMF's Multimod macroeconomic model show that current estimates of such savings translate into about a 5 per cent long-run increase in output in the major industrialised economies. In the medium term, although the deflationary effects of the shock would provide greater room to central banks to keep interest rates low, the simulation results also hint at short-term inflation risks if current demand outstrips supply in anticipation of higher future incomes.
