10 Preface to the Fourth Edition This book has three main purposes: first, to provide an elementary exposition of the balance of payments and of balance-of-payments adjustment theory; secondly, to describe the historical evolution and contemporary position of the United Kingdom's balance of payments, and thirdly, to critically appraise conventional balanceof-payments adjustment mechanisms, particularly in the light of the poor record of changes in nominal (and real) rates of exchange in rectifying balance-of-payments disequilibria in the world economy in the last decades. We emphasise the importance of non-price factors as determinants of export and import performance, which are reflected in the income elasticities of demand for exports and imports. As far as the United Kingdom is concerned, it is argued strongly in the book, particularly in Chapters 12, 13 and 14, that the balance of payments should be viewed in a growth context, and that at the heart of the UK's poor post-war growth performance relative to other. industrialised count ries is its relative neglect of the tradeable goods sector which is reflected in a low propensity of other countries to buy UK exports and a high propensity in the UK to import foreign goods (particularly manufactures). This problem cannot be tackled by exchange rate depreciation or monetary manipulation. It requires real economic policies of a structural nature related to the wider characteristics of goods, such as their quality, design, reliability, marketing and delivery. Exchange rate depreciation simply ossifies the industrial structure and makes producers temporarily more competitive in the export of goods with given characteristics which were the source of payments weakness in the first place. In our view, the UK's inferior economic record in relation to other countries is largely a function of its balance-of-payments strait jacket caused by the slow x

11 Preface to the Fourth Edition xi growth of exports and high propensity to import, and until this underlying weakness is rectified, the UK will be condemned to a low growth rate (and the spectre of rising unemployment) whatever other domestic policies are pursued. The idea that countries may be constrained in their growth performance by balance-of-payments weakness leads to the concept of balance-of-payments constrained growth. We formally derive a formula for a country's growth rate consistent with balance-of-payments equilibrium which turns out to be a remarkable predictor of growth rate differences between advanced industrial countries since the Second World War. Since the book was first published in 1980, it has been widely used as a preliminary text on balance-of-payments theory, and as a source of reference on the performance of the UK balance of payments. This fourth edition provides the opportunity to bring up to date all the tables relating to the balance of payments, imports and exports, the commodity and geographie composition of trade, the exchange rate, and so on, and also the text relating to the history of the UK balance of payments. The tables and text now extend to 1989/90. In addition, the analysis and exposition has been extended in several places. The most significant change. which has led to coauthorship of the book, has been the addition of two new chapters on the capital account of the balance of payments and on the determination of exchange rates. A detailed analysis of these two topics was a major omission from previous editions. Other changes include the following: the book continues to argue strongly that the focus of balance-of-payments policy ought to be on the current account, but in Chapter 1 there is a fuller account of why the current account of the balance of payments matters for the functioning of the real economy. It has become fashionable in some quarters to argue that current account deficits do not matter if they are not government induced and can be voluntarily financed. We argue that they do matter. Chapter 4 on the balance of payments and the national economy retains one of its distinctive features of presenting the foreign trade multiplier relating imports to expenditure rather than to income, which is obviously more realistic if the import coefficients of various components of domestic expenditure differ. In this chapter, the worsening trade-off between the balance of payments on current account and the level of unemployment in the UK is also highlighted. Chapter 9 extends the history of the UK balance of payments to 1990 with particular emphasis on exchange rate policy

12 xii Preface to the Fourth Edition and the worsening current account deficit in the latter years of the 1980s. Chapters 10 and 11 contain up to date information on import penetration and export performance in the UK. Chapter 12 on the balance-of-payments equilibrium growth rate reports recent work by other researchers of applying the model of balance-of-payments constrained growth to a range of countries for the most recent years. We also show how the model can be used for simulation and forecasting purposes. Chapter 14 on the balance of payments as a structural problem has an extended discussion of non-price factors as determinants of trade performance, and gives the results of some tests of the theories of non-price competition. The link between balanceof-payments weakness and deindustrialisation in the UK is further developed in a new Chapter 15. In the original writing of the book a debt was incurred to a number of organisations and individuals. The Economic and Social Research Council (formerly the Social Science Research Council) financed the initial research on the structural aspects of the UK balance of payments. The Treasury and Department of Trade and Industry provided statistics. Mr John Goy and Mrs Julia Stevens of the University of Kent Library obtained and checked references. The editors of Banca Nazionale dei Lavoro Quarterly Review, Applied Economics, the Oxford Bulletin of Economics and Statistics, the Journal of Common Market Studies and the National Westminster Bank Quarter Iy Review gave permission to reproduce certain material which first appeared in their journals. Finally, colleagues - Richard Disney, John Craven, Charles Kennedy, Bob Dixon and Thea Sinclair - read the first edüion and helped to improve the book with their constructive comments on various chapters. For this new edition we must also thank Euclid Tsakalotos for constructive criticism; Keith Povey and Steven Gerral'd for editorial assistance, and Celine Noronha for typing various drafts of the manuscript.
