Foreword 



The research leading to the publication of this volume was sup- 

 ported by the World Bank as well as by the Economic Growth 

 Center, an activity of the Yale Department of Economics since 

 1961. The Center is a research organization with worldwide ac- 

 tivities and interests. Its research interests are defined in terms of 

 both method of approach and subject matter. In terms of method, 

 the Center sponsors studies which are designed to test significant 

 general hypotheses concerning the problem of economic growth 

 and which draw on quantitive information from national eco- 

 nomic accounts and other sources. In terms of subject matter, the 

 Center's research interests include theoretical analysis of eco- 

 nomic structure and growth, quantitative analysis of a national 

 economy as an integral whole, comparative cross-sectional stud- 

 ies using data from a number of countries, and efforts to improve 

 the techniques of national economic measurement. The research 

 program includes field investigation of recent economic growth in 

 twenty-five developing countries of Asia, Africa, and Latin 

 America. 



The Center administers, jointly with the Department of Eco- 

 nomics, the Yale training program in International and Foreign 

 Economic Administration. It presents a regular series of seminar 

 and workshop meetings and includes among its publications both 

 book-length studies and journal reprints by staff members, the 

 latter circulated as Center Papers.
