The redistributive effect of health care finance in twelve OECD countries.

The OECD countries finance their health care through a mixture of taxes, social insurance contributions, private insurance premiums and out-of-pocket payments. The various payment sources have very different implications for both vertical and horizontal equity and on redistributive effect which is a function of both. This paper presents results on the income redistribution consequences of the health care financing mixes adopted in twelve OECD countries by decomposing the overall income redistributive effect into a progressivity, horizontal inequity and reranking component. The general finding of this study is that the vertical effect is much more important than horizontal inequity and reranking in determining the overall redistributive effect but that their relative importance varies by source of payment. Public finance sources tend to have small positive redistributive effects and less differential treatment while private financing sources generally have (larger) negative redistributive effects which are to a substantial degree caused by differential treatment.

Equity in the finance of health care: some further international comparisons.

This paper presents further international comparisons of progressivity of health care financing systems. The paper builds on the work of Wagstaff et al. [Wagstaff, A., van Doorslaer E., et al., 1992. Equity in the finance of health care: some international comparisons, Journal of Health Economics 11, pp. 361-387] but extends it in a number of directions: we modify the methodology used there and achieve a higher degree of cross-country comparability in variable definitions; we update and extend the cross-section of countries; and we present evidence on trends in financing mixes and progressivity.

Formation of a tablet: a site and bond percolation phenomenon.

The concepts of percolation theory are used to elucidate the formation of a tablet by compression of particulate matter. The process of compaction can be considered as a combination of site and bond percolation phenomena. Because of effects of different particle size and shape of the particles in a powder bed and effects of brittle fracture and plastic flow, moisture content of the powder, and finite size of the tablet, no sharp percolation thresholds are expected. Thus, it is interesting to test the validity of the fundamental equation of percolation theory: the power law X = S(p - pc)q, where X is the system property, S is the scaling factor, p is the site occupation or bond formation probability, and q is the critical exponent. This model is, in certain cases, only rigorously valid close to the percolation threshold (range, [+/- 0.1 pc]). Combination of the Heckel equation with an equation derived earlier for the properties (X) of tensile strength (sigma t) and deformation hardness (P) yields a power law with q = 1, S'(sigma t) = sigma tmax/(1 - pc), and S(P) = Pmax/(1 - pc). With respect to the simplifying assumptions made, the power law agrees well with the experimental results obtained. Substantial improvements in the interpretation of the compression-compaction process are possible with these findings, and some interpretations differ from previous ones in earlier publications.

[Evaluation of measures to reduce cigarette consumption in Switzerland].

Policy instruments were examined to reduce cigarette consumption in Switzerland. The results can be summarised in two points: a) Tax increases and anti-smoking publicity (health education) are effective measures to reduce cigarette smoking. The effect is especially pronounced when both instruments are combined. b) The effect of a ban on advertising could not be examined for Switzerland due to lack of data. Results of studies abroad lead to the assumption that cigarette consumption can be influenced more by the tobacco tax and anti-smoking publicity than by a ban on advertising. This is by no means to say that such a ban would have no effect.

[Economic aspects of prevention. Efficiency and structure of the health care system].

The structure of the health care system has been examined, the health care sector being defined as all measures taken to promote and preserve good health. A review of the international literature came to the following conclusions:--The correlation between medical care and health status is at most very limited.--The empirical evidence suggests that efficient preventive programs--both for primary and for secondary prevention--would be possible.--We therefore come to the conclusion that the division between medical care and prevention is not optimal and that furthering prevention at the cost of medical care would increase the efficiency of the health care sector. Conclusive statements concerning the efficiency of additional preventive measures are not possible with the research undertaken to date.

[Economic instruments for promotion of prevention].

The classical economic instruments for influencing individual behaviour are regulatory and sumptuary taxes as well as subsidies. Regulatory taxes are forced payments, which are fixed exclusively to influence a group of individuals in the manner required by the government. Sumptuary taxes are levied in order to eliminate differences between private and societal costs (e.g. with smoking). Here the externality tax takes first place. Subsidies, finally, are a special aid, which should motivate the recipient to behave in a certain way. They can--in the same way as regulatory and sumptuary taxes--, by influencing the price structure, be employed in various ways to partronize preventative behaviour.
