The Reading School of International Business is widely understood in the field of international business (IB), management and economics to embody a stream of conceptual, and theoretically-driven empirical research, and consists of a group of economists and international business scholars who share a common approach to analyzing multinational enterprise and foreign direct investment.
 Some are based in the Department of Economics and in Henley Business School at the University of Reading, England, but membership is international.
 The Reading School builds upon the pathbreaking theoretical work of Peter Buckley and Mark Casson on internalization theory.
 This was complemented by simultaneous work by John Dunning as he developed the eclectic paradigm of international business as an envelope explanation containing three principal drivers of foreign direct investment, comprising ownership (O); location (L); and internalization (I).
 The Reading School approach continues through the work of its academic disciples around the world, as well as through The John Dunning Centre at Henley Business School, University of Reading, under the directorship of Rajneesh Narula.
