Abstract: Health care is a highly complex, dynamic, and creative sector of the economy. While health economics has to continue its efforts to improve its methods and tools to better inform decisions, the application needs to be aligned with the insights and models of other social sciences disciplines. Decisions may be guided by four concept models based on ethical and distributive justice: libertarian, communitarian, egalitarian, and utilitarian. The societal agreement on one model or a defined mix of models is critical to avoid inequity and unfair decisions in a public and/or private insurance-based health care system. The excess use of methods and tools without fully defining the basic goals and philosophical principles of the health care system and without evaluating the fitness of these measures to reaching these goals may not contribute to an efficient improvement of population health.

Health care is a highly complex, dynamic, and creative sector of the economy. It “sells” hope, beyond health, in an environment of different parties, interests, and incentives. It deals with uncertainties and preferences in a context of asymmetry of knowledge, information, and power to make decisions (Ferraz, unpublished data, 2015).1 Due to its model structure (insurance), complexity, and the evolving nature of science and human expectations, health care should be planned for the long term and be based on solid ethical and distributive justice principles.
The model currently in place in most countries (public, private, or mixed health care system) is based on sharing the financial risk through an insurance system. The high degree of innovation in the sector in an environment of limited resources creates the need for timely and continuing appraisal of evidence and for understanding and integrating individual and societal sets of values and preferences when making choices.
Many health economic tools and methods have been developed and used to inform decisions. Sometimes we are somewhat distracted by the passion with some sophisticated methods and forget that the real world health care system problems and choices are much simpler (although tougher) than we expect. We are definitely not doing all we can in terms of improving population quality and quantity of life and, unfortunately, we are far from overcoming the challenge of optimizing allocative efficiency. In some specific cases, we may have improved technical and productive efficiency; however, as Peter Drucker well describes, “There is nothing quite so useless, as doing with great efficiency, something that should not be done at all”.2
While health economics has to continue its efforts to improve its methods and tools to better inform decisions, the application needs to be aligned with the insights and models of other social sciences disciplines. To improve health care in our society, we will have to consider implications beyond health care.
Recently, the label “value-based decision making” has become popular to characterize what in our belief should justify our choices. However, at least two basic (but often ignored) aspects of a health care system need to be defined: 1) the economic framework in which it operates and 2) the underlying priority setting models based on ethical agreements and distributive justice.
It is important to note that health care systems built on a societal insurance model should prioritize need (demand) and not supply of products and services. Systems based on supply are much more prone to be influenced by specific interests over and above societal interests, and they usually favor abuse and waste and, consequently, increase health care inflation and disparities. Supply induces demand, which frequently may not be driven by need.3–5
Hope-driven systems, aligned with supply-driven systems, encourage premature introduction of new technologies that are not fully critically evaluated. We should aim toward systems anchored in priority setting agreements with a high preference for scientific evidence and fulfillment of health care needs, in short, value-driven systems. Concurrently, scientific progress and innovation should not be inhibited, but its uptake should be driven by market needs and be aligned to the economic perspectives. Where restrictions or barriers to the development of innovative technologies for priority areas become necessary, appropriate compensation should stimulate ongoing innovation.
In a value-driven system, decisions should be guided by transparent criteria and definitions, without prejudice for winners and losers. Faced with difficult decisions in health care, arguments of groups with particular interests – based on religious, philosophical, moral, individual, or political beliefs – often win over scientific evidence or societal priority setting conventions, and any decision has the potential to be dramatically questioned by individuals and interest groups despite any strong health economics evidence.
Decisions may be guided by four concept models based on ethical and distributive justice (Figure 1):libertarian, communitarian, egalitarian, and utilitarian.6–10 Societal agreement on one model or a defined mix of models is critical to avoid inequity and unfair decisions in an insurance-based health care system.

Health care systems in many developing countries, such as Brazil, currently face major challenges: how to meet the demand for 21st century standards of health care and technology with funds that remain lower than what developed nations invested 30 years ago.11,12 Currently, Brazil invests only US$1,043 per capita annually on health, which equals only 31% of the Organisation for Economic Co-operation and Development (OECD) average.13 Moving from a supply-based to a demand-based system and anchoring the prioritization process in a model that respects the ethical principles and favors distributive justice in health care will be essential. Right now, it is possible to identify different Brazilian health care policies that follow one of all four concept models, and we are still far from achieving any desired equity and efficiency in health care.
In conclusion, health economics should not be used as “l’art pour l’art”. The excess use of methods and tools without fully defining the basic goals and philosophical principles of the health care system and without evaluating the fitness of these measures to reaching these goals may not contribute to an efficient improvement of population health.
According to Frederic Bastiat, a French political economist, an act gives birth not only to an effect, but to a series of effects. The first effect is immediate. Others may unfold in succession and often are not seen. He also defined the difference between a good and a bad economist – the one takes account of the visible effect; the other accounts for the visible effects and the ones to be foreseen. The bad economist pursues a small present good, which may be followed by a great evil to come, while the true economist pursues a great good to come, at the risk of a small present evil.14
Jorge Mautner, a Brazilian composer and singer stated in a song that “Liberty is beautiful, but it is not infinite. I do want you to believe, liberty is the consciousness of the limit!”15
To enhance the chance of achieving an equitable and efficient health care system, we have to acknowledge: 1) the need to discuss the economic model of health care systems with all ethical and distributive justice consequences; 2) the need to pursue a great good to come, at the risk of a small present evil; and 3) society has to be conscious that liberty is beautiful, but has a limit!
