Although the impact of globalisation on national economies is well recognised, there is a lack of quantitative information available on the issues involved in debates on the subject. This publication provides guidance on how to measure and interpret measurements of the extent and intensity of globalisation. The manual defines concepts and puts forward guidelines for data collection and fine-tuning of globalisation indicators. The proposed indicators apply mainly to the economic activities of multinational enterprises, particularly in relation to trade, technology transfer and foreign direct investment.
