In May 1984, the Pinhas Sapir Center for Development at Tel Aviv University sponsored a conference on economic policy in theory and practice in memory of Abba P. Lerner (1903-82). Abba Lerner had been deeply concerned with the development of economic theory and the formula tion of economic policy in light of the theory. This volume contains the proceedings of this conference. This conference is the third in a series of international conferences of the Pinhas Sapir Center for Development. 1 The centre is concerned with all aspects of development. Pinhas Sapir, Israel's seventh Minis ter of Trade and Industry (1955--63) and third Minister of Finance (1963-74), had been deeply concerned about development in Israel and contributed greatly to it. The book puts together fourteen papers presented at the Pinhas Sapir Conference in memory of Abba Lerner, held at Tel Aviv University in May 1984. The papers cover a wide range of issues related to economic policy: public debt, budget deficits and inflation, world debt problems, resource allocation and taxation, efficiency of various forms of market organisation, and a positive theory of the state. The contributors of the papers are: Alan Auerbach, Eitan Berglas, Willem Buiter, Rudiger Dornbusch, Ronald Findlay, Stanley Fischer, Jacob Frenkel, David Fresko, Sanford Grossman, Oliver Hart, Zvi Hercowitz, Daniel Kovenock, Anne O. Krueger, Franco Modigliani, David Pines, Assaf Razin, Michael Rothschild, Efraim Sadka, Thomas Sargent, Neil Wallace, Yoram Weiss, Robert Willig and John Wilson. We would like to thank Mali Nudel and Rina Elman of the Sapir Center who ran the office and co-ordinated the conference activi ties. Note 1.

His comprehensive contributions to modem economics in a variety of fields were so basic that they seem to have become a common economic knowledge which has lost the identification of their origin. It was Lerner who introduced the concept of 'functional finance', and who first raised the dilemma between high unemployment and price stability. It was Lerner who brought up the basic differentiation between demand inflation and administrative inflation and who introduced the idea that monopoly position is a relative concept that can be measured by the relative difference between price and marginal cost. It was Lerner who laid the foundations for the modem theory of capital, and in the field of international economics left us the first proof of the rules on complete equalisation of factor prices by free trade in products. And it was Lerner who first showed that import and export duties had exactly equal influence. Lerner was apparently also the first to look for the factors and conditions required for an optimum currency area. A detailed and comprehensive account of Lerner's
