9 ix Notes on the Contributors Alan Williams is a (part-time) Professor of Economics at the University of York, mainly working on the appraisal of public expenditure in various fields. His interests in health care have been reflected in his membership of the DHSS Chief Scientist's Research Committee, the Royal Commission on the NHS, and the SSRC Panel on Health and Health Services Research, and in his publications on the application of economic analysis to medical care systems. Besides his interests in health and medical care, he has also worked on problems of water resource development (he was a member of the Yorkshire Water Authority and of the National Water Council) and on evaluating the effectiveness of police and criminal justice systems for the Council of Europe (he was formerly a member of the SSRC's Social Science and Law Committee).

10 Introduction ALAN WILLIAMS Economists, like doctors, are seeking to extend life and relieve misery. In the case of doctors, the premature mortality and the misery is due to disease. In the case of economists, it is due to scarcity. Health economics stands at the interface between those two important fields of human endeavour. It is a relatively young sub-discipline of economics, not really amounting to any significant volume of work until about 1970, and at that time mostly concentrated in the USA. British health economists drew, and still draw, on the work of American colleagues, but the political and institutional frameworks within which health care is provided in the USA are so different from those in the UK (and in many other European countries), that it was necessary for the subject to develop along rather different lines in order that it could offer ideas, and empirical results, that are relevant to the much more egalitarian ideologies, and much heavier reliance on tax funding, which characterise health care provision in most European countries. In such a rapidly developing field it is difficult to know just when to offer your wares to the public for appraisal and comment, but the enormous interest in public policy suggests that anyone with something useful to contribute should not hold back. We health economists think we have something useful to contribute, so in this volume we have offered up some of our wares for public inspection and discussion. In this enterprise we have been joined at one point by a medical sociologist, and at another by a social geographer, features which emphasise the undoubted fact that other disciplines, besides economics, will also have something to say on the topics addressed in this volume. We neither seek nor claim an exclusive franchise! The volume opens with my own presidential address, which attempts to sketch out the whole territory in which health economists Xl

11 Xll Introduction operate, even though only a selection of their work can be included here. Those who want a much more comprehensive picture of the scope of the subject should consult C. A. Blades et a/., An International Bibliography of Health Economics (1986), which contains annotations on over 5000 published works in the English language going back as far as 1914! It should satisfy even the most voracious appetite! The principle adopted for selecting topics for inclusion here was to span a wide range of topics, and to show that there is more to health economics than the economics of health services. The broadest issues addressed are those concerned with inequality and injustice (Illsley and Le Grand; Peter Townsend; Mooney and McGuire; and Mohan), since these place health and health care in the context of socio-economic inequalities more generally, and pose fundamental questions about the potential role of the health-care system as a countervailing force. It is an important area of debate in which even the underlying facts, and the causal mechanisms at work, are in dispute. No-one familiar with the literature can seriously doubt that there is a major social problem to be addressed. The differences show up when one tries to decide exactly what notion of justice we are seeking to put into effect, and where it would lead us, and with what effect. It is to be hoped that the contributions offered here will help clarify the issues and put them in perspective. There are also two papers on the relationships between unemployment and health, and on the economics of reduced smoking, both of which deal with issues that go beyond concern with the health care system itself. Gravelle demonstrates the intricacies of establishing causal links between phenomena which, however strongly related they may seem at first glance, may be the result of a variety of complex mechanisms, each of which would have different implications for policy. Joy Townsend works her way through the implication of reduced smoking showing the various ramifications of that trend, which seems currently to be the specific behavioural change which would do more than anything else to improve people's health. She shows that many of the claimed deleterious side-effects on the economy, and on the public finances, are, at the very least, exaggerated, and quite probably non-existent. It is a challenging analysis. Thus, coming closer to the health service and its problems, we have the papers by Buxton, Drummond and Maynard. Drummond's contribution concentrates on the general methodological stance that

12 Alan Williams xiii underlies the economists approach to evaluative work, and argues in favour of a more significant role for the discipline of economics in both the formulation of problems and in the range of data collected when controlled clinical trials are being planned. This will make the findings much more relevant to the world in which health services operate. Buxton's work on the economics of the heart transplant programme is an excellent example of this kind of evaluative work. It also illustrates the role of health economists in a multi-disciplinary enterprise, where they are able to play a significant role in both problem formulation and data collection and analysis, but are nevertheless sensitive to the interests, expertise and knowledge of non-economists, and, at the end of the day, have to interpret their findings so as to address a public policy issue in terms that make sense to the policy-makers themselves. Finally, Maynard considers the incentive structure generated by the manner in which health services are financed, and suggests that many of the more persistent problems (and conflicts) which seem to be so intractable within the NHS might be more readily resolved with the more imaginative use of 'internal' markets (so that the time costs of different activities are made visible to the decision maker - often a doctor - and that person has an appropriate incentive to seek to minimise them). All in all, it is a varied menu, but one which certainly does not exhaust all the possibilities. The potential of health economics to improve the lot of struggling humanity has so far scarcely been tapped, and if this volume enables non-economists to come to a better appreciation of its scope and methods, I shall be well satisfied.
