G. Antille Gaillard Equity and Health This article raises the problem of equity in the health system in Switzerland. <...> Three dimensions of the concept of equity are taken into consideration: the inequality in the financing of the health system, the inequality in the distribution of the state of good health, and, finally, the iniquity in the access to health care. <...> In conclusionwe observe that the state of good health does not depend strongly on income but that it exists some iniquity in the access to health services from specialists and that the income inequality is increasing due to the financing of the health system. 1. <...> Introduction the universities of Geneva and Lausanne and the Swiss Polytechnic School. <...> The paper presents a summary of this research and some of the results with respect to Switzerland. <...> For a country like Switzerland where this financing relies, either directly or indirectly through other economic agents, primarily on households, it is important to know if these expenditures are supported by the households proportionally to their financial capacities or not. <...> In Switzerland the expenditures on health per head are very high, but the health situation of the population is yet very satisfactory. <...> Thus, the question is whether there is inequality between the distribution of the state of health of the population and the income of the households. <...> This second dimension of equity in health raises the problem of the measurement of the state of health, as the results of this measurement are necessary to build a concentration curve to evaluate if the good health is more concentrated in the upper classes of the population. <...> Finally, the third dimension of equity concerns the access to health care. <...> Health Expenditures in Switzerland and its Financing from a Macro-Economic Point of View In 2005, the total cost of the Swiss health system was 53 billion of Swiss francs; this amount corresponds to 7,059 Swiss francs per head. <...> The cost of health represented 11.6% of Gross 1 This research is part of the IRIS (Integration, Re´gulation et Innovation Sociales) program which joins together the Universities of Geneva and Lausanne and the Polytechnic School of Lausanne. <...> The program is funded by the «Confe´rence Universitaire Suisse» and by the already quoted institutions. 67 Российскошвейцарский семинар по эконометрике и статистике he specific theme of «Equity and Health» was examined by the Laboratory of Applied Economics and the Department of Econometrics of the Geneva University as part of a research program called «Sciences, Life, and Society»1 , launched in collaboration with Domestic <...>
