The South African medical schemes market reflects, more than any other market, one of the realities of our age: government intervention into private markets. There is probably no market which is subject to more government intervention than the healthcare market, including the medical schemes market.
Two similar questions about this reality spring to mind. Firstly, why should governments intervene in private markets? And then secondly, why do governments intervene? Although on the face of it the two questions are very similar, the answers to the questions are vastly different. Taking a cue from Sir Lionel, economic science should be able to provide answers to these questions, the first question is now answered; why should government intervene?
The point of departure to this explanation is free, competitive markets. Free markets do not imply no government intervention. Indeed, the truth is the very opposite. John Locke argued that governments are formed to protect life, liberty and property. To this, the Americans added ...and the pursuit of happiness.
Insofar as free competitive markets are concerned, after a very long struggle by the mid-1800s, it was understood that free competitive markets produce optimum outcomes. So as far back as 1859, John Stuart Mill could proclaim: “But it is now recognised, though not until after a long struggle, that both the cheapness and the good quality of commodities are most effectually provided for by leaving the producers and sellers perfectly free, under the sole check of equal freedom to the buyers for supplying themselves elsewhere.”
This became the generally accepted position which existed long before 1947, when Paul Samuelson, the future Nobel Laureate, articulated that “…there has never been absent from the main body of economic literature the feeling that in some sense perfect competition represented an optimal position.”
An answer springs to mind from the question itself; government intervention is justified where the specific market is clearly not producing the optimum outcomes obtainable from the free, competitive market. Should a market produce sub-optimal outcomes that market can be said to be subject to market failure, a notion made popular by Francis Bator (1958).
For example, in cases where monopolies exist it could be argued that the government should intervene to eliminate monopolies. Alfred Marshall, England’s most famous academic economist had argued free competitive markets provide goods at the lowest price giving to consumers what he termed a consumer’s surplus. Free competitive markets eliminate monopoly profits. Thus, if monopolies exist then the optimum market does not.
Against the background of this view, America introduced the first modern government intervention with the passing of the Sherman-Anti-Trust Act of 1890, ostensibly to combat monopolies. In addition, back in England, Marshall’s protégé and successor Pigou argued the economic system should produce to society the maximum total economic welfare. This was a vague concept.
Pareto, an Italian engineer put some flesh on those bones by pointing out that the actions of some may impose involuntary costs on others; or as is usually said by economists, impose externalities on others.
For example, producers may impose pollution on society. Government intervention in the form or regulations requiring polluters to clean-up the pollution they create would be justified intervention; the ‘Pareto optimal standard’ became accepted. If a market imposes externalities, government intervention could be justified to deal with the externality.
In the free, competitive market insurers determine the premium using easily, inexpensively determined, risk factors, as for example, age. These factors have a direct bearing on the cost of claims. Thus, for example, taking age as a risk factor, typically the average healthcare spending on persons over 65 is about six times that of the spending on children and three times of that on a person of working age. Age would be a costlessly determined risk factor, to be taken into consideration when setting the premium.
In medical schemes, because of the intervention, high and low-risk members are pooled. This market is not Pareto-optimal since high-risk members impose externalities on low-risk members. The medical schemes market is thus subject to extensive market failure. In this case, the government intervention has created this market failure. More importantly, government intervention was not introduced to eliminate market failure. Economically speaking this intervention is not justified.
In fact, economists could go further and state that government intervention into the South African medical market creates market failure. The medical schemes market, economically speaking, is a sub-optimum market. This then leads to the second question, why does government intervene? This question is answered knowing the government intervention has caused market failure.
This second question is more difficult to answer but we can be guided to an answer relying on the view of John Stuart Mill (1863) when he wrote that all actions are undertaken to achieve some end and the rules which govern those actions must take their whole character and colour from the end to which they are subservient. The answer to the second question comes from answering two other questions. Firstly, what was the end, or purpose of the intervention, and secondly has that end in fact been achieved?
