The acceleration of the internationalisation of business and the division of labour has been led by improvements in technologies and communications, decreased barriers to trade, increased competition and the growth of multinational enterprises (MNEs). Employers, government organizations and unions, practitioners and academics are increasingly concerned with locating comparable statistics. This article reviews employment relations and labour market data for ten major industrialized market economies (IMEs) and discusses some of the challenges in the measurement and interpretation of such data. For a fuller discussion of such data, and of the ten IME, see Greg J. Bamber and Russell D. Lansbury (eds) International and Comparative Employment Relations 3rd edn, to be published by Sage, London, and Allen & Unwin, Sydney, in mid-1998.
